Psychologist who writes for fox news blames feminism for Weiner’s sexting scandal.

So this article was published a couple of months ago but I just ran into it a few days ago and it was just too ridiculous to pass up commenting on.

What Weiner’s sexting scandal tells us about young women today

Dr. Keith Ablow, a psychologist who is part of the fox news medical team, writes this article. He seems to think the feminist ideal of sexual liberation is what’s really to blame for this scandal by teaching women to enjoy sex outside of marriage. Dr. Ablow seems to think this is a “man’s job.”

The sexual liberation of women has liberated them to be just like men—who, whether anyone likes it or not, often enjoy sex outside of emotionally-connected, longstanding relationships.

Unfortunately for Ablow he gets a number of facts wrong in this article. First he seems to think that feminists seem to have no issues with Weiner’s actions. To be clear we tend to have different problems with it than Ablow has, I don’t think there is anything inherently immoral with premarital sex. However, Weiner was clearly in the wrong, he was lying to his wife. Further suggesting that the women Weiner sent these photo’s too are somehow responsible for his behavior is more than a little sexist, and suggesting that men never had affairs before feminism is more than a little bizarre. Clearly such affairs have been common throughout history even in cultures without all of those “evil” feminists.

However, he clearly thinks his arguments have scientific merit and the feminists are just being political when they suggest that there is no psychological difference between men and women; so let’s look at his actual argument:

From my perch as a psychiatrist talking to thousands of people a year, I can tell you that the average young woman no longer balks at sexting, watching pornography or being the aggressor sexually in a relationship.

But I will tell you that, from what I hear in my office, the girls actually feel a whole lot worse about it, in their hearts, than the boys.  Because, you see, girls and boys, are not the same.

In this argument we actually get a picture of the scientific methodology he employed to come to this conclusion. My conclusion is that his methodology is dangerously sloppy. You will noticed he, at no point, mentions any studies that demonstrate that the average women feels psychologically traumatized by unmarried consensual sex. I can only assume that he quotes no studies because he is unaware of any.

So what is the evidence he brings to the table? His brings up his work with his patients and says that women feel worse in their hearts than men do. Now some people wanting to defend him might at this point say that this guy has a degree in his field and has practiced psychology for years, and don’t I believe in trusting scientists? Who am I to question his authority in this field, since I clearly have no degree in psychology. Well, it’s true I have no degree, but I actually trust the scientific method much more than I trust individual scientists. This is important because Ablow clearly fails to follow scientific principals in his analysis.

You see Ablow uses a flawed sample set. In this case he is making generalizations about a whole population based upon a small self selected sample set. In general if you want your figures to be representative of the whole population then a self selected set is a bad way to do it. This problem is further complicated by the way in which the group self selects itself. In this case all of his patients come to him with some kind of psychological issues, so to assume that facts about the sexual neuroses of his patients can be used to generalize about about all women is very sloppy science indeed.

Further, his statements are vague and metaphorical (they feel worse in their hearts) which makes it impossible to tell if his opinions about the sexual neurosis of even the small sample set he worked from are reliable. It is entirely possible that his biases about sexual behaviors have colored his perception of his clients feelings on the matter.

The sad thing is that if he actually went looking for it there is a lot of studies out there on gender psychology, like this one:

Men and Women May Not Be So Different After All

So a further problem for Ablow is that there are good studies that actually run contrary to Ablow’s claim.

…Statistically, men and women definitely fall into distinct groups, or taxons, based on anthropometric measurements such as height, shoulder breadth, arm circumference, and waist-to-hip ratio. And gender can be a reliable predictor for interest in very stereotypic activities, such as scrapbooking and cosmetics (women) and boxing and watching pornography (men). But for the vast majority of psychological traits, including the fear of success, mate selection criteria, and empathy, men and women are definitely from the same planet.

I suggest reading the whole study, as it demonstrates a much more careful and thoughtful methodology than Ablow does, which is why I find it ironic that he ends with this:

Some gender roles developed because of psychological facts, not in spite of them.  And when feminists urged and urge that we throw out all of them, they do a disservice to females and to the truth.

Ablow’s willingness to use his flawed data, in place of the good data which contradicts his desired conclusion, makes it painfully obvious that his reasoning is motivated by his political and religious ideals, not a desire for truth. It does not qualify as good science. Further, he subtly engages in victim blaming and sexism throughout his article, which makes it difficult to believe he is overly concerned about women’s rights.

The Blaze talks about evolution, also never read the comments on a Blaze article.

I ran across an article about creationism and evolution over at the Blaze today.

Evolution vs. Creationism: Did God create humans in our current form?

The article starts out by referencing an article on Yahoo news that Virginia Heffernan wrote announcing she is a creationist. Their treatment of her article is incredibly biased. They talk about her making a “slew of ideological enemies” implying that the disagreement with her was ideological and not because of legitimate factual problems in her argument, and calls her case “compelling.”

They don’t even really seem to understand her case very well because if you read her article she seems to call herself a creationist only because she has no idea what that word actually means. She is clearly not promoting the type of creationist thinking that is common to Ken Ham and other typical fundamentalist creationists. She doesn’t claim the earth was created in a few days, and she admits the bible is contradictory. The only problems with evolution she talks about come from evo-psych, a field that is regularly criticized by fellow skeptics for it’s just so stories, which is the same thing she criticizes it for.  

She also seems to drift into some relativist philosophy at the end of the article, which is also quite in incombatable with the positions of most creationists. Essentially, believe in god even if it isn’t true because it’s a better story than the one science sells. Now, not only do I think this is a bad approach to truth, I happen to disagree with the notion that the bible spins a better tale than science.

As to whether she accepts evolution in general or she is just somewhat ignorant and wrongly conflates evo-psych with all of evolution, I honestly don’t have enough information to say one way or the other. What I can say is that Heffernan is not a typical creationist, and in fact she seems to not even know what the term means when it comes to most of the blaze’s readers.

The article itself is full of plenty of bad science, most notably the assumption the notion that the results of the necessarily self selected poll they ran on their website is at all useful.

A much more specific and pointed question asked respondents if man evolved “with no involvement from a higher power.” There was a clear consensus among the 4,008 Blaze readers who responded. While six percent answered affirmatively, an overwhelming 94 percent of the readers who took the poll rejected this notion.

This is particularly interesting due to the fact that the Pew Research Center estimates that about six percent of the nation considers itself secular and unaffiliated with a faith — a prime group that would embrace the idea that mankind evolved without God’s hand guiding the process. Of course, the Blaze poll on this subject was not a scientific one, but the proportional similarities are still worth noting.

In the last line here they acknowledge that the poll was not scientific but then go on to act as if the study was actually valid anyway since the figures happen to coincide with figures for a completely different question in a population based poll done by Pew. (which is not exactly the gold standard for science anyway) They also, at certain points, imply that most of their readers disbelieving in evolution amounts to evidence that there is good reason to doubt evolution.

As bad as the article was, the comments were fare worse, of the kind that makes me question humanities ability to think rationally about anything. One commenter claims to be a young earth creationist physics teacher, which just makes me sad. or this one:

Well, since naturalism requires a scientific explanation OR an eyewitness account, and evolutionists don’t have an eyewitness account to corroborate their position, nor a scientifically defensible explanation, (speculation and wild assumption is not scientific), and Judeo/Chrsitianity actually has an EYEWITNESS account of what occurred at the beginning, I’m going with the BEST evidence which is that God created the heavens and the earth and mankind and the animals and all that was created.

Yes, this person just argued that believing the bible is the more scientific option because there were eyewitnesses to the events in the bible and evolution has no eyewitnesses. What I find so ridiculous about this argument is that, even by fundamentalist Christian standards, it isn’t true. By those standards Genesis was written by Moses around 2,000 B.C. several thousand years after creation. If people can’t even keep their arguments internally consistent with their own world view how can they hope to understand complex scientific principals?

Math….pffft why would we need that to understand global warming?

I’ve been reading different arguments about global warming lately and I ran across a claim on the sites of several people arguing against global warming.

Man-made carbon dioxide emissions throughout human history constitute less than 0.00022 percent of the total naturally emitted from the mantle of the earth during geological history.

I’ll admit when I first read this I thought, is this really true? Doesn’t this hurt man made global warming arguments? Then I took a moment and considered the statement more carefully. the 0.00022 number provided is based upon a comparison of carbon dioxide for the entire geological history of the earth, which if you remember is 4.3 billion years. However, human cased global warming is a recent issue caused by high CO2 output by humans. Almost all of this CO2 output has happened in the last two to three hundred years, which means the real question is how much extra CO2 have we added to environment recently not in all of earths history.

Let’s not stop here though. Assuming this number is correct (I couldn’t verify anywhere) then lets calculate what percentage of of the earth’s CO2 has come from humans in the past couple of hundred years. Fair warning I have never considered math to be my strongest subject so feel free to point it out to me if I make a mistake in my calculations.

First we will base the calculations on the last 300 years.  So to find out what percentage of 4.3 billion 300 is we divide them.

300

divided by 4,300,000,000

= 6.9-8  or 0.000000069

 
So 300 is only 6.9-8 of 4.3 billion, but man made carbon dioxide, most of which was caused in the last 300 years amounts to 2.2-4 which is a much larger number. How much larger?
 

2.2-4

divided by 6.9-8

roughly 3,188.4

That’s right, the amount of CO2 produced by humans is almost thirty-two hundred times more than the amount of CO2 naturally produced by the earth in the same time frame, even based on the number provided by those arguing against man made global warming. So, this number, is actually strong support for man made global warming instead of evidence against it. Making the argument that it is a very small percentage of the CO2 produced through all of human history is like claiming a flood doesn’t exist because the amount the amount of rain that caused it is a very small percentage of the overall rain fall in that area in the last hundred years.

Another blogger who thinks evolution is an atheist conspiracy…

Recently the Kentucky Board of Education updated their science standards, and surprisingly enough I don’t have much of a complaint about that. Usually when when I pickup a story about science standards being changed, particularly in highly religious states like Kentucky, it’s because some creationist group is trying to insert creationist propaganda into the science curriculum. Surprisingly, this time the Kentucky board actually backed reasonable standards. On evolution the board stated

the fundamental, unifying theory that underlies all the life sciences…“there is no significant ongoing debate within the scientific community regarding the legitimacy of evolution as a scientific idea.

They also rejected the idea of pulling information about climate change out of science text books. They point out that the standards do not advocate for a particular political response, but do present climate change scientifically supported which seems to be exactly the way a science class should handle the issue.

Unsurprisingly many creationists and unhappy with these standards. While looking up information on this story I ran across a particularly irrational screed on The Matt Walsh Blog.

Christianity has done more for science than atheism ever could

Of course he makes an error right in the title of the post by assuming that evolution and atheism are synonymous. Considering Kentucky's religious background is is quite likely that that the school board is made up mostly of Christians. They are promoting evolution in the science curriculum because it is good science not because they are secretly atheist agitators as Matt seems to think. He gives two reasons that he thinks “progressives” are celebrating this decision.

1) It will put us in line with many other states, which is great because we all know a diverse and enriching education must be in utter uniformity with the national collective and in compliance with the federal agenda.

I always find it funny that a group of people who believe that everyone who doesn’t believe in their religion will suffer eternally in hell start criticizing atheists for our lack of “diversity,” but in the end they don’t actually understand what diversity is all about. I’m all in favor of diversity in regards to individuals personalities, likes and dislikes, etc. However, facts are still facts and to promote a version of diversity that allows people to have their own facts is to promote a relativist notion of truth. The odd thing is that I know for a fact that most Christians would regard this notion as false. Even Matt here wants Christianity taught in science class, not other religious beliefs just Christianity. How positively uniform of him.

2) The criteria calls for a renewed emphasis on man-caused climate change and, of course, evolution. Evolution — atheistic, nihilistic, materialistic, mindless evolution — must be taught as fact, without other ideas presented to compete with the theory.

All good science is technically materialistic because science is involved in measuring things it can actually measure. As soon as Matt, or anyone else, can propose a way for science to empirically measure supernatural entities and events then the supernatural can qualify as science. The thing is most Christians reject the notion that one can empirically measure such things. Christians often don’t want their beliefs to be potentially falsifiable the way scientific claims are so they reject the standards of science from the start and then demand that science respect their beliefs. It is not unreasonable to suggest that people like Matt pick one or the other. Evolution, on the other hand, is falsifiable and does meet scientific standards. If Matt thinks that those standards should be changed that is another discussion, but it is a philosophical one not a scientific one.

He then goes on to say that “members of the church of atheism” are the one really hostile to science, history, and philosophy. While I will admit that there are plenty of atheists out there who are ignorant on those topics, this is really entirely irrelevant to science standards since ideally those setting such standards should be knowledgeable about science regardless of their beliefs. The real irony, however, is that one sentence after he extols the Christians ability to properly value philosophy he uses the following quote from the apologist G.K. Chesterton

a multiplicity and subtlety and imagination about the varieties of life which is far beyond the bald or breezy platitudes of most ancient or modern philosophy

So he claims Christians are better and philosophy while simultaneously saying that philosophy is nothing but breezy platitudes?

He then tries answer the question of how science and religion are compatible with a litany of completely irrational arguments and biased ethnocentrism. He claims that Christians have the scientific high ground because:

As a Christian, you aren’t just a member of a religion — you’re a member of a rich intellectual tradition unmatched by any group, anywhere in the world.

It’s like he is just completely unaware of all of the rich intellectual traditions around the world that are unrelated to Christianity. He continues in this vein later on in his post so I’ll comment further there.

He then claims that an atheist recently told him that “Christians have always hated science.” I’ll actually agree with him that this is a rather bizarre thing to say. However, he metaphorically shoots himself in the foot when he calls atheists “historically illiterate fools,” and then later on in the post he complains that atheists are mean and insulting to Christians. He also claims that Modern science wouldn’t exist without religion which to me seems like an equally bizarre statement, as well as un-provable,

He claims that Christianity is the major driving force for science and he tries to demonstrate it by listing scientists who are Christian. In this he subtlety engages in a correlation vs. causation fallacy. He assumes that because these scientists were Christian that Christianity was the cause of their scientific achievements. However the pertinent question in the evolution vs. creationism debate is not whether or not Christians can be good scientists, I will happily acknowledge that they can.

The question is whether or not modern Christian fundamentalism is philosophically compatible with science. Anyone who knows history well, as Matt claims he does, would know that Christian fundamentalism is a movement that started in the 19th century in part as a reaction to what some people viewed as an encroachment into religious questions by science. This is important because beliefs like the scientific inerrancy of scripture, which are common to modern evangelical Christians in the U.S., were popularized if not outright developed by fundamentalism.  This is why it is particularly interesting that all of the scientists that Matt lists, Copernicus, Kepler, Galileo, Pascal, Descartes, Newton, Kelvin, Mendel, Boyle, lived before the 19th century. It is undeniable that their version of Christianity differed from the modern fundamentalism that informs Matt’s views is some significant ways.

He devotes a great deal of his article to just repeating the claim that Christianity is responsible for science because by listing a number of Christians who influenced western scientific development while simultaneously ignoring the fact that many of the Christians were maligned by other Christians from their time for undermining religious beliefs. I suppose Matt thinks those people weren’t real Christians like the scientists were.

He then criticizes an atheist who sent him an email full of personal attacks and insults. As I have said before I actually agree that this is a bad way for atheists to present themselves in these debates, but no one can prove their own position correct by simply pointing out that some people who disagree with them are doing so in an insulting manner. Further Matt made a point of being insulting towards atheists at multiple points in this post so all I have to say is this:

pot-kettle-black

He does expand on his earlier ethnocentric statements with this gem.

When western scientific knowledge came to places like China and India in the 1600′s, it came by way of Christians and their science-hating Christianity

I’m not sure what to make of this. If I take this statement at face value he sounds like an 18th century imperialist who thinks the only good ideas come from western civilization. Perhaps he only said this because wrote himself into a corner by trying to claim that science owes Christianity everything.

Just so we know this is not true, other civilizations have invented great pieces of technology and advanced science in myriads of ways. China invented gun powder. The first blood transfusions were done by the Incas. The list could go on for days. However, it’s even a mistake to think that Christianity was around for all of the scientific developments even in the western world. Galileo may have proved the heliocentric universe, but Greek Mathematicians proved the earth was round using geometry (which they also invented) hundreds of years before Christianity existed. Last I checked both of these discoveries were instrumental in the development of western science, so by Matt’s logic we should still be worshiping Greek god’s for teaching us Geometry.

At this point he makes the most bizarre statement this entire post.

But are we Christians all “idiots”? Well, I don’t mind if you say that about me, but was Da Vinci an idiot? Aquinas? Shakespeare? Mozart? Washington? Locke? Martin Luther King Jr? Edison? Tesla? Alexandar Graham Bell? Adam Smith? Marconi? Chesterton? Lewis? MacDonald? Dickens? Faulkner? Tolkein? Marco Polo? Neil Armstrong? Magellan? Columbus? Henry Ford? All of these guys are idiots, along with the scientific pioneers I mentioned earlier?

His statement here clearly implies that everyone he just listed here is Christian, but this is untrue, at least by the these people’s accounts of themselves.. Edison was a deist. Tesla’s views are debated by historians, but he seemed to be some kind of universalist or possibly deist. Neil Armstrong was, again, a Deist. Adam Smith was at most a deist, and may have been an agnostic or an atheist. He was certainly close friends with David Hume who many consider an atheist, and smith never evokes god as an explanation in his any of his philosophy. Alexander Graham Bell considered himself agnostic.

Columbus I will give him, but also point out that Columbus was kind of an awful human being. Columbus wrote in his log when he first met the Arawak Indians that, “They would make fine servants,” and “With fifty men we could subjugate them all and make them do whatever we want.” Also, he discovered America, not because he was brilliant, but because he reached a foolish conclusion and got lucky. That is he badly underestimated the size of our planet. The only reason he and his crew didn’t die in on a boat in the middle of the ocean due to his miscalculation was because there was a giant undiscovered continent half way between Europe and India.

Certainly, while most of the others were likely Christian the fact that he clearly got so many wrong makes me wonder how much he actually knows about history. He claims atheists are rewriting history to suit their narrative, but given his lack of knowledge about these well known historical figures how would he know?

Towards the end he says we should not teach atheism in school, which is one of the few things he says which I actually agree with. I don’t want public schools teachers telling students god doesn’t exist anymore than I want them telling students he does. Where he gets it wrong is assuming that teaching evolution is equal to teaching atheism. This should be obviously wrong given that fully half of the U.S. believes in evolution while less than 10% of us are atheists.

His last paragraph really wraps all of his biases about atheists up into a nice package.

Really, we must get atheism away from education before we all end up like the modern atheist’s greatest prophet, Nietchsze, who died insane and naked, eating his own feces in a mental institution. This is not the sort of fate we should wish upon our children.

Think of the children, for goodness sake.

First of all Nietzsche (he misspelled his name) went insane because he had syphilis. Matt’s blasé dismissal of a serious illness which would cause insanity in anyone regardless of their religious predilections is both offensive and scientifically duplicitous. To assert that being an atheist will cause people to eat their own feces is not only factually inaccurate, it is blatant fear mongering. This is not the scientific and rational thought he claims to be arguing for. Earlier in the article he claimed that atheists have to twist facts to justify their position but what is he doing here if not blatantly twisting facts?

So Matt Walsh I assert that I am thinking of the children. I will be a father soon my self, and it is my devotion to objective moral ideals, scientific curiosity, and intellectual honesty that leads me to my atheism, my skepticism, and notions of social justice. I feel strongly about these things precisely because I want to leave this world a better place than I found it…you know, for the kids.

Kentucky’s school prayer petition makes blatantly false claims

3185-Lack-of-School-Prayer-Opened-Door-to-AIDSThe American Family Association of Kentucky has put up a petition to put prayer back in Kentucky schools. They claim that the law is ok because Florida and Mississippi have passed similar laws, though I suspect it is just a matter of time before the laws a struck down for church state separation violations. The AFA doesn’t even try to disguise their intent, they say outright the goal of putting prayer in school is to convert students. In their own words:
STUDENTS PRAYING AGAIN WILL EVENTUALLY TURN OUR COUNTRY BACK TO GOD!
Now, I suspect that even if Kentucky passes such a law it will, within a few years, end up on the docket for judicial review and the law will be shot down amidst cries from the AFA that the liberal elite are destroying this country. So while I am concerned that there is a trend of states passing laws which have already been deemed unconstitutional, what I’m really concerned about is the blatantly false scientific claims they make as part of the petition. Claims that apparently no one bats an eye at, perhaps because they fit a narrative that this petitions audience already wants to believe. The narrative being that American society is failing because it doesn’t trust in god. So let’s take a look at the scientific claims which the petition makes:
Prayer was in our schools for over 200 years before the anti-God forces took it out in 1962. After prayer was removed from our schools, teen pregnancy went up 500%, STD’s went up 226%, violent crime went up 500% and SAT scores went down for 18 years in a row, opening the door for the AIDS epidemic and the drug culture.
Of course the notion that before the supreme court ruled on school prayer in 1962 and 1963 school prayer was common in all 50 states and totally uncontroversial is simply historically inaccurate.  But lets look at the four main scientific claims made here.
First, they claim that teen pregnancy has climbed 500% since 1962. This one is easy because I actually wrote a post about this claim last year which you can read here. In this article I point to a set of statistics found here which show that far from a 500% increase, since 1962 the teen pregnancy rate has fallen by almost 100%, in 2008 and more recent figures show even further decline. This claim is not only poorly supported, it seems to be an outright fabrication. Of course if they have alternate figures I can’t judge them since they fail to provide references for their claims.
image
The next claim is that STD’s have gone up 226% since 1962. Like the first one I seem to be unable to find any reports with this claim. Further, the claim is more difficult to judge than the one about pregnancy because while pregnancy is binary (you either are or you aren’t) STD’s come in many different kinds, some of which are very dangerous and some of which are fairly harmless, particularly if treated quickly. Though, in part, it is the very fact that STD rates are difficult to judge that make this figure so suspect. For instance, the infection rates of specific STD’s rise and fall at different rates as well, sometimes one will go up while another will go down in the same year. So if the figures for a less harmful one went up while one that was more harmful went down by a similar amount is the STD problem unchanged or is it improved? Further, if the figures go up for a particular STD, depending on how the figures are gathered, this might only indicate that more people are seeking medical treatment, not that infection rates have increased. For these, and other, reasons generalized rates like the one given in this petition are practically useless. They tell us less than nothing.
So how did this number hold up to the figures I was able to gather? I did find a paper here through the CDC which gives rates of infections for various STD’s. The rates fro Chlamydia only went back to 1990 so I can’t judge that one entirely, the rates have climbed since 1990 with women suffering from the majority of the cases but at a rate of about 375 per 100,000 it isn’t like there is an epidemic or anything.
I was, however, able to get graphs stretching back to 1941 for both Gonorrhea and Syphilis. Gonorrhea infections seem to have been on the rise in the early 1960’s all the way until the mid 1970’s. It was at about 150 out of 100,000 in 62 and climbed sharply to almost 500 by 1975. However, that trend was reversed in the 1980’s and by 1995 the rate was down to around 100, lower than it was even in the 1950’s. Syphilis, meanwhile, was at it’s highest rate of nearly 600 out of 100,000 in 1945. This was probably due to soldiers returning from WWII. The modern figures barely register on the graph with numbers under 50.
image image
Of course there are other STD’s we could look at. I imagine the rate of increase for AIDS between 1962 and now is off the charts since it didn’t exist then, but in general without some rather startling figures coming from some other form of STD it is pretty clear that the claim of a 226% increase in STD’s came from the same place their claims about teen pregnancy came from.
The third claim was that crime has gone up 500% since 1962. I found numbers for this here. This one could actually have some teeth if you measure the the straight numbers of crime without regard to the increase in population we have seen since 1962. For instance the number of Robberies in 1962 was about 110,000, and in 2011 they were about 354,000. That is an increase of well over 300%. However, when you note that the population of the U.S. has increased by nearly 1.7 times that increase falls to only about 190%.
However these numbers are not consistent. The murder rate, for example was around 8500 in 1962 and are around 14,600 in 2011. That increase is actually consistent with the increase in population, leaving the per capita murder rate relatively unchanged since the 1960’s. In fact, Murder numbers actually peaked in the 90’s and have been falling for nearly 20 years now. In fact pretty much every crime rate has been falling since the mid 1990’s so the only way you could get anywhere near this 500% figure is by looking at 20 year old data.
The last claim made is that SAT scores fell 18 years in a row. Once again I was able to find actual figures for this quite easily. This one has a grain of truth in it since the average score in 1980 was 424 compared to the 473 that was the average in 1962. However a new scale was introduced in 1967 which may muck up the comparison. If you only look at the averages from the new scale from 67 onward there was a downward shift in the 60’s and 70’s, but that trend reversed in the mid 80’s and has been climbing. Interestingly, numbers in the math section have been rising more than numbers in reading. Further the downward trend could have been due to increased college attendance or the fact that test standards were changed several times which could have made the test more difficult.
Of course the biggest problem with this argument is that even if their numbers were correct, and I have shown that they are not, they have done nothing to show any causal relationships between these figures. They assume, for no reason whatsoever, that these figures changed because of a change in school prayer, when it should be obvious that things like teen pregnancy and STD’s are affected by thousands of different factors. Of course acknowledging that there might not be an easy fix for our problems is usually a hard thing to do. We want our fixes to come easy, and to the unskeptical it is comforting to think that if they can just get society to change one thing everything will fall into place and be great. Seldom is this tendency seen in more prevalence than with the religious right.

Ken Ham waxing about how atheists are persecuting Christians.

A story has been floating around the blogosphere about a man who was upset to find his child was being taught nonsense science claims at a private school he was sending his child to.

Children are being taught in the classroom that brontosaurs were refereed to as a behemoth in the the book of Job and are encouraged to answer the question "The next time someone says the earth is billions (or millions) of years old, what can you say?" with the answer "Were you there?"


Picture of the offending quiz.

Of course Ken Ham could not put up with the affront to justice that this father, who expected this school to teach science in the science classroom, represented and Ham fired back with a response.  


Now mind you, nothing in the published story even states the religious beliefs of the father in this story so there is no reason to assume he is an atheist, but this doesn't stop Ham from going off into conspiratorial ramblings about how atheists are out to get Christians. He really seems to believe that Christians are all some poor belabored minority.  

He even presents some "examples" in a box to the side of the article of persecution they face:
Billboards promoting atheism and attacking Christianity have popped up across the country.
Because apparently free speech is now persecution.
The American Humanist Association has launched a special website for children to indoctrinate them in atheism.
The site he is referring to is this one kidswithoutgod.com. It isn't aimed at converting children but giving resources to children who already don't believe.  However, even if it were aimed at conversion so what? Christians spend millions if not billions of dollars a year on hundreds of thousands of programs aimed at converting children to their religion. This website is totally passive, you have to go to it to see the content, yet many of the aforementioned Christian programs actively seek out children even when doing so violates church state separation. Why is it totally fine for them to put their ideas out there for others to consider but when we do it it's "indoctrination?"
An atheist rally in Washington DC last year had a special promotion to encourage kids to attend their atheist camps.
The program his talking about is Camp Quest. It is not an "atheist" camp, it's a secular came for children that focuses on teaching kids about science and critical thinking. It's a good program and I plan on sending my kids to it once they get old enough. I have good memories of some of the camps I went to when I was younger (minus the religious teachings of course) and I want my kids to have such memories too.

In any case, this is typical damned if you do damned if you don't criticism. Christians criticize atheists for doing nothing but attacking Christianity but offering no replacements for the "helpful social programs" that churches offer such as summer camps for kids.  Now that our movement has had a chance to establish itself we start putting together such programs and now we are accused of "indoctrinating" kids.
Atheists have been increasingly using terms like “child abuse” to describe the efforts of Christians who seek to teach their children about creation, heaven, and hell.
Several prominent skeptics including Lawrence Krauss have claimed that teaching creationism or teaching them that god sends unbelievers to hell are mild forms of child abuse, in much the same way that teaching your child that the earth is flat would be a mild form of child abuse. I happen to agree with the sentiment, however no one is suggesting that this is the same as physical abuse or that the state should necessarily take a child away from a parent for this sort of thing, though clearly we hope the children will manage to learn better than their parents and try to provide the facts to make that happen.
Many atheists claim that children belong to the community, not to their parents.
I don't know any atheists who think this. However, I do think that, though a parent has quite a bit of leeway to parent as they wish, children are still individuals separate from their parents who have rights and deserve a modicum of protection by the state from certain kinds of parental actions. I don't believe, for instance, that Christan Scientists have a right to allow their children to die from lack of medical treatment because of their belief that modern medicine is immoral.
Atheists have actively opposed any effort in public schools to even question a belief of evolution or suggest there are any problems with it.
And now we get to the dead horse Ham likes to beat, evolution. It should be noted that it is not only atheists that oppose the teaching of creationism or intelligent design in classrooms. There are theistic scientists who promote evolution like Catholic Ken Miller, so Ham's claim is not even accurate, but there are good reasons to promote good science in science classrooms, and evolution is good science.  It's nothing but Ham's biases and lack of understanding of science that leads him to believe that evolution is untenable.

Christians are not being persecuted when they aren't allowed to promote odd pseudo-science in the classroom anymore than a crypto-zoologist is being persecuted when the biology class won't let him share his evidence for Bigfoot and the Loch Ness monster.

If Ken Ham spent as much time actually learning something about science as he did complaining about how atheists are persecuting him he would realize how silly all this actually sounds.

Science reporting on evolution still bad

Ran across this article last night.


The article is about evidence that dust mites who are currently parasites may be evolving into a free living organisms. The reason it is talked about as reverse evolution is because dust mites used to be free living organisms before they became parasitic. The article is written as if the author is presenting a startling new find that is over turning scientists previous belief that evolution does not work in reverse. The idea that evolution is working towards some sort of goal is inaccurate

The main problem here is that the author seems to confuse the evolutionary process which is basically genetic variances, with the taxonomical or behavioral changes that are sometimes produced. That is, in order for evolution to reverse the species would have to follow the exact same genetic changes one step back at at time, considering all of the possible variances it is easy to imagine that, while this is technically possible, it is not very likely. This is actually a concept called Dollo's law of irreversibility.

However, it is entirely possible for a species to follow an evolutionary pathway that leads something very similar behavior or taxonomy to an earlier or separate species. It's called Convergent evolution and we have know about it for a long time because there are already examples of it everywhere. For instance, most birds, many insects, and bats all use wings to achieve flight but the genetics that created those wings are each completely different, and we can see this in taxonomical differences in these wings. Another good example is whales who, despite their earlier ancestors moving out of the water, moved back into it. They did not stop being mammals but they did evolve many traits to deal with aquatic living that are very similar to fish. Again whales did not go backwards, they did not use the same genes as fish, they evolved a new set of genes that created similar taxonomy.

There is nothing to suggest that dust mites have followed some path backwards to an earlier form, but why should the facts get in the way of science reporters making up attention grabbing headlines on their articles to increase their readers? People will know what they really mean right? It's not like there are systematic misunderstandings of evolution in this country or anything.

Science and Religion compatible? Not exactly.

I ran across an interview yesterday on Discover between Keith Kloor and Daniel Sarewitz.


I actually agreed with most of it but Keith asks a question about whether religion and science are compatible and I took some issue with the answer.
DS: There are lots of scientists who are also religious, so as an empirical matter science and religion are apparently not incompatible. ... We have binary arguments because they are easy and mindless and comforting–no one has to acknowledge ambiguity or complexity; everyone gets to be right. Binary arguments are a refuge for orthodoxies, and atheism can be as much an orthodoxy as religion. I say this as an atheist. I am not an agnostic. I don’t believe in god(s) and I think those that do are incorrect. But I think humans have lots of different ways of making sense of their experience of the world, and my way happens to be atheism.
Now, honestly I agree that many people engage in binary arguments to comfort themselves but ironically I think this is exactly what Sarewitz is doing. When someone asks the question "are religion and science compatible?" there are several potential meanings to this question.  One possible meaning, the one Sarewitz assumes, is to ask if religious people are capable of being scientists.  If that is what is being asked then I agree with him.  It is obvious that religious people can be scientists.  Ken Miller, for instance, is a Catholic but is a also a good biologist who has strongly advocated for science standards and stood up against creationism being taught in schools.

The problem I see is that when people ask "are religion and science compatible?" they are rarely asking if religious people are capable of being scientists.  They are often asking if religion and science are philosophically compatible or they are asking if various religious claims match with the findings of science.  These are very different, and much more interesting, questions.

To examine this let me ask a question that I think is analogous.  Is homeopathy and science compatible? If by this question we are asking if homeopaths can be scientists then I would also answer yes.  A person might be a homeopath and work in a field like electrical engineering or theoretical physics and do quite well with their work in that field.  Of course if they were to speak about or try to work in the fields of medicine, biology, and perhaps chemistry it is likely that their belief in homeopathy would be a hindrance, but there are still many areas where they could produce good science.  This is because many scientists work in very narrow fields and are not necessarily any more knowledgeable about fields outside their purview than the average person.

However, if by "is homeopathy and science compatible we mean to ask if the findings of homeopathy fit with findings of science the answer is a resounding "no." Further, to believe in homeopathy is to necessarily claim things about chemistry and biology that we have good reason to think are false.

Now, granted to be "religious" is a lot more vague than to be a homeopath.  There are hundreds of religions and thousands of interpretations of each one of them.  However, many religious people do make claims that do not fit with science or at the very least have not been proven using science.  If a person claims to believe prayer can heal, he does so in direct opposition to the available evidence. (anecdotes don't count) If a person claims to believe in a god, well his claim may not be contradicted by known evidence, (depending on their definition of god) but neither is it supported by any.  This does not mean the person is a terrible scientist in the area of their expertise but it does mean they have accepted as true claims which have not been demonstrated with evidence.

Ironically I will quote Jesus here when he pointed out it was impossible to have two masters.  A religious person may practice science for years without any of their findings contradicting their religious beliefs, but the question is what will that person do if they run into something that does contradict their religion?  Are they willing to accept that their beliefs are wrong in favor of the science or will they deny the new findings to hold onto their beliefs?  Of course this is not just a problem specific with religion, anyone can choose to hold onto their beliefs in contradiction to the currently observable facts, but to do so is always counter to the scientific method.

Some good news out of New Orleans.

I've written about several of Louisiana's weird attempts to push creationism in the last year so I suppose it's nice that I can write something positive about the state in what will probably be my last post of the year.


In a unanimous vote the Orleans Parish school board voted to give creationism the boot.  It even went as far as to specifically name books written to fit the atrocious Texas science and history standards.
No history textbook shall be approved which has been adjusted in accordance with the state of Texas revisionist guidelines nor shall any science textbook be approved which presents creationism or intelligent design as science or scientific theories.
I was also particularly impressed with this part of the ruling.
No teacher of any discipline of science shall teach any aspect of religious faith as science or in a science class. No teacher of any discipline of science shall teach creationism or intelligent design in classes designated as science classes.
With all of the nonsense currently going on in that state it is nice to know some people there still care about education.

The "evils" of porn

I occasionally read articles on lifesitenews.com, If you have never read it, it's pretty much a mill for conspiracy theories and rants against "liberal plots" like science and measurable data. 

I don't often write criticism of things I find there, but this series of articles caught my attention.


He is writing about the "evils" of porn, but his argument ends up sounding strange, creepy and anti-sex.  Now before I get into the criticisms let me say a few things about my own view so there is no confusion.  I do, in fact, watch porn on occasion.  I say this without the slightest bit of shame, sexuality is an important part of our nature and I think it is unrealistic to expect people to simply turn this part of themselves off until they get married.  Even most Fundamentalists admit this, since they are well aware of how many people watch porn and have premarital sex despite the general injunctions against both.  Think about it for a second, the church forbids both murder and premarital sex.  However, few people have a problem resisting the urge to murder but almost everyone has a problem resisting the urge to have sex.  This should tell us right away that these are very different things.

Now, to be clear I am not saying that the use of porn is a totally great thing without any potential negative consequences.  STD risks, and abuse are both potential risk for people who work in porn.  And there are studies that connect high amounts of porn use to erectile dysfunction, which, from what I've read seems to be caused by an over stimulation of the dopamine receptors, causing them to loose sensitivity.  However, risk is in everything we do.  Many people join the military even though that job carries with the potential risk of being dead or permanently maimed yet people do it proudly.

This brings me to the articles in question.  I'm going to be criticizing parts 2 and 3 primarily.   In the second part of his article he seems to want to discuss the topic reasonably, and shows that he has at least a passing familiarity the way pornography is dealt with in modern psychology.  However, like most apologists his reasonableness does not last, he quickly descends into pseudo-science and preachy claims, even ones that are a detriment to his article.

Ran across this very interesting video by Neil deGrasse Tyson today.  Thought I'd share.

Dr. Oz and Raspberry Ketone

Occasionally I get spam emails, and by occasionally I mean very very often.  I usually ignore them, most of them get caught by my spam filter but occasionally one gets through like the email that sent me this link:




This page is talking about the fat loss effects of raspberry ketone.  It is full of grandiose claims and comments by "users" which sound exactly like the way people in an infomercial are paid to talk about a product.  The link to the video of Dr. Oz speaking about it on the page is broken but I did manage to find a link to the same spot on his show from YouTube.  I suggest watching it.  

Dr. Oz, despite his credentials, has a habit of promoting quack medicine, and I'm hardly the first to speak about it.  A lot of people watch him and trust his advice so it is disappointing that he promotes unproven treatments without really any reservations.  He gives everyone a neat little demonstration where he puts some balloons in liquid nitrogen and they shrivel up while he tells us that raspberry ketone does the same thing to fat cells, because apparently an analogy equals proof in T.V. world.

To be fair, he does let his viewers know that they should not use this by itself and should instead use it only as part of a larger weight loss treatment plan, but he is totally positive in his review of effectiveness of the pill.  He never once mentions that there have been no medical trials done with humans showing positive effects for raspberry ketone.  Even his own site says ketone works best "when paired with regular exercise and a well-balanced diet of healthy and whole foods."  You know, those things that have a proven effect on weight loss all by themselves.

I did manage to find one study done with rats published back in May.  It seemed to have some promise, but unless I am misunderstanding the study it only showed promise in preventing weight gain.  The study was not designed to test ketone as a treatment to undo past weight gain.  Further, there are no studies done on humans that I found, nor did he mention any.  So to state without the slightest reservation that this product works is a huge stretch.  This is further compounded by the fact that weight loss supplements come out all the time and they never deliver on their claims.  This is not to say they are all useless, some do have limited effects, but they have never lived up to the hype.  What are the chances that this will be the one that does?

Louisiana is in a worse state than I imagined.

I wrote a while back about Louisiana passing a voucher program that was likely to push creationism onto students by sending them to Christian private schools.  Well the bill passed and has been put into effect this year.  Thanks to a friend I got a link to a website which had scanned three pages from a 5th grade text book currently being used in in Louisiana voucher schools and being paid for by tax dollars.  Anyway, here is the link.


The book is not teaching "strengths and weaknesses" or "Intelligent design" it is overtly and explicitly teaching science from the perspective of Christian religious bias.  It goes as far as quoting bible verses as evidence that dinosaurs lived with humans and claiming that the flood is responsible for the geological column.

Here is a couple of gems from the book.  A table that explains the big bang as a "sudden explosion" and describes humans as the "highest level of animal" according to evolution.

One thing that struck me was there insistence that the findings of science are nothing more than the results of the biases injected by the people doing the science.

They say:
Man makes judgments about the evidence of fossils based up his beliefs. A man who believes God's record of creation and history will look at fossils in one way.  A man who believes in evolution will view fossils in a different way.
They then go on to give the student an activity to read several articles written by "creationists" and "evolutionists"  to try to determine what the writers bias is.  This is such an absurd and jumbled approach to science it is difficult imagining children getting anything out of it.  It is bad enough they are teaching these kids bad biology, but they are teaching them a horrible approach to science in general.  It is, of course, obvious that everyone has a bias, but the whole point of the scientific method is to attempt to eliminate those biases.  A person can start from any hypothesis they want and no matter how biased it is the predictions it makes will either turn out to be true or false.  If the predictions are false then the hypothesis fails.

The main thing they fail to mention is that the reason creationism doesn't count as science is because it makes no meaningful predictions about the world.  Take big bang which they inaccurately describe as a "sudden explosion," when it was first proposed the calculations predicted certain types of radiation should still be present in the universe as a result.  Measurements were taken and the radiation was found, thus there was evidence that it happened. (though not definitive proof)

Now take the creationists view point, "God created the heavens and the earth" by their own description.  What predictions can one make from that?  To ask the question differently what differences would we expect to see between a universe that God created and one that he didn't?  The fact is we don't know, we have no idea what differences there would be between those two things if any.  So with no predictions there is no way to test, or falsify as Karl Popper would have put it, the hypothesis that "God created the heavens and the earth."  Thus this is not a mere matter of competing beliefs as this text book wants to present it as.

The science in this book is so bad it should be criminal to lie to students this badly.  Late elementary school is a great time to cultivate students interest in science and instead they choose to squash it with ludicrous pseudo-science.  Now thanks to Louisiana they are using tax money to promote this stuff to students who may not even share their religion, because their parents have been told that sending their child to a private school is a guaranteed way to get a better education.  The evidence in this book says differently.

Revolution...worst sci-fi ever.

I've been watching a few episodes of a new science fiction series that has come out this year called Revolution.  Now, I am used to a certain amount of difficult to believe stuff in science fiction.  We all suspend disbelief to a certain extent when we watch it, but I have rarely run into anything in sci-fi so completely contrary to basic science as the plot of this show.

For those who have not watched here is the basic premise of the show.  "Something" happened one night and caused all electrical devices to stop working permanently at the same time.  The show then flashes forward about twenty years or so and the power is still off and people are living at a technological level similar to the early 19th century.  Nothing that requires electrical power works at all.

Now, ignoring anything else in the show this is the most nonsensical plot device I have ever seen, the person that wrote this could really have benefited from setting in on a physics class for jr. high children.

Alternator.
To explain, lets start with some basic education on how electricity is produced, for those who might not know. Let's start with this item on the right.  This is an alternator for a car. (cars also stop working in the show) Alternator's produce electricity to power your car and charge the battery so that the battery can be used to start your car.  How exactly do these work?  They aren't magic, hell they aren't even very complicated.  If you look at this one you will see copper wires bunched together on the outer edge of the device.  This bunch of wires runs around the outer edge of the alternator in a circle. A fan belt runs around the pulley on the end and down to another pulley attached to the drive shaft.  This causes the pulley on the alternator to turn while the engine is on, which in turn causes a magnet located in the middle of the wires to spin.  And....that's it.  It's called a dynamo and this is the primary way we have been producing electricity since the principal was discovered in the early 19th century.

But surely this is a simple device right?  Power plants produce electricity using a far more complex system right?  Nope, power plants use dynamos too, the only real differences are the size of the dynamo and what they use to power it's rotation.  Power plans typicality use steam instead of a drive shaft.  That's right steam, perhaps our world is closer to steam punk that any of us realized.  The steam is of course created by heating water with a variety of fuel sources oil/coal/nuclear/solar etc. but the technology of the dynamo has changed very little in nearly two centuries.

Batteries work a bit differently since they effectively store electricity using chemicals, it is still being produced using the same basic fundamental force.

What causes this to function is a force in physics called electromagnetism.   The magnetic field causes the electrons in the copper atoms to excite and move between atoms, and this is what generates the electricity.  The important thing here is that electromagnetism is one of the four fundamental forces in physics that make our universe work.  These are strong and weak nuclear forces, gravity and electromagnetism.

So here is where we get to what makes the plot of this show horrible.  What killed the electricity?  It couldn't have been some form of EMP, because that would only kill electrical devices that are on at the moment of the EMP, and would have no permanent effect on older cars or machinery that were not dependent on computer systems to work.  Also even if it killed all power plants people still know how to build a dynamo.  A twelve year old could build one out of some copper wire and a magnet in his dad's garage, so it would be bad, but in a few years people would rebuild power plants and move on.  In the show, however, everything stops working all at once, even battery powered devices all within seconds of each other.  No one rebuilt anything because, the show tells us, electricity simply doesn't work anymore.

In order for this plot to work the "something" that caused all electrical devices to stop working would have to interrupt electromagnetism at a fundamental level to prevent dynamo's from producing electricity.  Electromagnetism is not just some neat trick that lets us power computers, it is one of the most fundamental forces in nature, and without we could not continue to live, even our bodies depend on it, it turns out that there are lots of electrical reactions in our body.  Ever heard of a neuron?  These are the cells in the brain that produce thought, and they do so through an electro-chemical reaction.  So if a device that could interrupt electromagnetic force were turned on we would all die almost instantly, since your brain would no longer be able to tell you to breath, your heart would stop beating, etc etc.  It makes the entire plot one of the most laughably unbelievable things I've ever seen.

For this reason alone Revolution gets my vote as one of the worst pieces of sci-fi to come out since Plan 9 from outer space.

So THAT'S who wrote the pilot for revolution.

I don't even know what to say.

Recently U.S. Representative Paul Broun, a republican from Georgia and who, unfortunately for the U.S., is a physician and sits on the House Science, Space and Technology Committee had this to say:
“God’s word is true. I’ve come to understand that. All that stuff I was taught about evolution, embryology, Big Bang theory, all that is lies straight from the pit of hell. It’s lies to try to keep me and all the folks who are taught that from understanding that they need a savior. There’s a lot of scientific data that I found out as a scientist that actually show that this is really a young Earth. I believe that the Earth is about 9,000 years old. I believe that it was created in six days as we know them. That’s what the Bible says. And what I’ve come to learn is that it’s the manufacturer’s handbook, is what I call it. It teaches us how to run our lives individually. How to run our families, how to run our churches. But it teaches us how to run all our public policy and everything in society. And that’s the reason, as your congressman, I hold the Holy Bible as being the major directions to me of how I vote in Washington, D.C., and I’ll continue to do that.”

His beliefs are strange enough, the fact that this guy is on a committee that decides how to spend government funds on science and technology is downright disturbing.  He calls him self a scientist, but last I checked calling oneself a scientist requires that one actually does science.  Has Broun published in any peer reviewed journals?  Particularly on these young earth claims he is making?  He seems to think they are obvious but can't really offer anything of substance. He just says, "That's what the Bible says."

Of course the scariest thing about his statements is that he is basically openly admitting his dominionist leanings by stating his intent to use the Bible to decide how he will vote.  How do people come to wield so much political power in this country when they are so painfully ignorant, openly anti-science, and driven to use their religious beliefs as the basis for law?  

If you think that guy is bad, then this guy will really break your brain.  


Charlie Fuqua, is a Republican candidate for the Arkansas House of Representatives and thinks the U.S. government should reinstate the Old Testament law that made being an unruly child a capital offense.
Even though this procedure would rarely be used, if it were the law of land, it would give parents authority. Children would know that their parents had authority and it would be a tremendous incentive for children to give proper respect to their parents.
I am going to humbly suggest that parents willing to use this sort of thing as a threat to garner obedience from their child shouldn't be parents in the first place.

Who votes for these loons?

How to say something about your product without saying anything.

There is a commercial 5 hour energy has been playing on my Hulu account quite a bit lately and I found it pretty funny. They asked 3,000 doctors (though didn't say how many actually answered) and the response?
Over 73% of doctors would recommend a low calorie energy supplement to their healthy patients who use energy supplements.
The way this is worded they basically said nothing of value.  The doctors say they would recommend a low calorie supplement to people who are already using one to begin with, so there is no way to determine if these doctors would recommend it to people using nothing at all.  Perhaps they only recommend it because it is better than using high calorie supplements that also do nothing, if the patient is going to use energy supplements anyway might as well turn them onto something low calorie right?

In addition they don't mention the 27% (a still pretty significant number) who didn't recommend it even within the very limited confines of the statements phrasing.  What were their reasons?

Unfortunately shady advertising techniques like this one are used precisely because they work on enough people enough of the time to make it profitable.  Laws can be useful to limit what advertisers claim to a certain extent, but as with this example it is often easy to come up with ways to say things that, while not outright lies, are intentionally misleading, thus circumventing the laws.  This is one of the reasons that education in skeptical thinking is so important.

Meat does not work that way.


I was on Google+ earlier today and this photo was posted under the Did you Know page:

With it was the following statement:
The watermelon is easily digestible, and will be excavated much faster than the burger and fries below. If the burger and fries remain in tact for 180 days, imagine how it must look inside your intestines! That stuff clogs you up, prevents the villi in the intestine from functioning properly, and results in malabsorption issues and GI tract problems. Not to mention a variety of other bodily effects that I could list for days on end.
The suggestion seems to be that because the burger did not decay in the same way it is unsafe to eat, they also seem to suggest that the burger will still remain in a persons intestines for 180 days.   Neither claim is accurate.  Now, I'm not suggesting that everyone should eat a huge pile of fast food burgers.  The stuff tends to be too salty and high in fat so there are health problems that can result from eating too much, I'm not debating that point.  However fruit and meat both decay very differently.  Bacteria need water to grow in, a watermelon, just as the name suggests, is mostly water, giving it a perfect place to grow a bacteria culture.  Any cooked meat, even not bought at a fast food restaurant, will not decay or mold if stored in a dry area, bread also drys quickly and fries would have most of the water cooked out of it.

Believe it or not this has been tested already.  Why Those Burgers Don't Rot, Decompose, or Molder Away.

Vouchers and schools and creationists, oh my!

I wrote last weekend about a school voucher program going on in Louisiana.  While I am against vouchers for several different reasons this is understandably a complicated issue with a lot of competing issues to consider.  NCSE published an article about it and I decided to revisit it in a bit detail.

Many people favor vouchers based upon an argument that says that people should have a right too choose.  I don't really see this as a solution to our problems in this area.  I think what I notice is that in politics there are two sides, one that argues that more government control will fix our issues and one that argues that less control will fix our problems.  Politics seems bereft of people, like myself, who wish that policies were made rationally instead of ideologically.  Sometimes more government control is good, sometimes less is, on a lot of issues the amount of government control seems to have nothing to do with the problem at all. 

In the school voucher debate, this seems to be much the same quandary, some people think by getting government out of education the problems we have will simply disappear.  I remain unconvinced of this.  It seems that our problems with education are more complex and require more thoughtful solutions than simply throwing up our hands and privatizing the whole thing.  After all, many other countries with public education seem to be doing just fine.  Further, I think that many politicians in favor of vouchers are simply using it as a smoke screen to promote their personal religion in schools.  Rep. Valarie Hodges that I wrote about in my earlier post basically admitted it was her goal when she backed out upon realizing that Muslim schools would receive money as well.  

Clear evidence that evolution is false...I guess.
For one thing, when the state starts giving money to the private schools now the state starts enforcing more limits and controls on those private schools, so it ends up in many ways not really different than the current system.  There are a few questions that are not answered though.  For instance, under the current law, teachers are unable to lead students in prayer in a public school, but they can in a private school, and the majority of private schools are religious.  Does the government step in and say no school organized prayers?  This would not go over well with the religious right, but if the state is providing funds to these schools allows these school organized prayers to continue are they not allowing states funds to be used to promote religion?  Do we want to allow that? What about creationists text books that teach the Loch Ness monster disproves evolution?  Yes, those books from ACE are, in fact, in use in some of the private schools in Louisiana.


However, some may say, what about the standardized test scores.  It is true that scores on standardized tests are usually higher in private schools, doesn't that prove that moving kids to the voucher system will improve their grades too?  Well, maybe, but then again maybe not.  Let's examine this a bit more closely.

I found a good break down of various statistics about private schools here: 


The statistics for their breakdown comes from the national center for education statistics so I think we can assume they are pretty reliable, a read though the statistics reveals that scores in private schools are indeed better, but this does not automatically mean that the voucher system will improve education.  There are a few things that need to be considered.  The question to be asking is why exactly do people in private schools do better.  I know people of the libertarian mind set seem to believe that the explanation lies in the natural checks and balances that exist in private enterprise which have no analog in government.  Lets just say I do not find that explanation very satisfying.  They may turn out to be right, but both government and private enterprise are run by humans, I have seen no evidence to convince me that private enterprise is less prone to corruption than government or that the reality checks in it are more effective.

First, I am going to point out something obvious.  Correlation does not equal causation.  I know we have all heard that before, but it is an important concept, there are other possible explanations for private school students doing better on tests than private schools are all better and education.  Don't misunderstand, many private schools probably are better in certain respects, but consider a few other hypothetical causes for this.  
  1. There is also evidence that students do better when their parents take an interest in their education.  Statistically speaking I would bet that parents willing to spend money educating their children take a more active role in it.  
  2. Another observation is that children who eat better diets growing up tend to have higher IQ's.  People who can afford private school are going to be more wealthy and therefore more likely to eat better. 
I could probably think of others if I tried but I came up with these two just setting around between calls at work.  Do they totally account for the difference? Probably not, but they do need to be considered before just assuming that vouchers will fix the problems facing education in this country.

There is one other thing I think needs to be considered.  Near the top of CAPE's page they give a breakdown of the tuition costs of private schools.  The numbers are from 2007-2008, but that is the most recent numbers I found online.  

The big thing I noticed here was that religious ($7,073) schools are much cheaper to attend than the non-sectarian variety ($16,247).  Cheaper by more than half in every case.  They give no reason for this, but I suspect that they are cheaper due to being supported in part by churches or other religious organizations.  The reason this is important is because of a piece of information I only discovered a few weeks ago in a conversation I had at TAM.  The amount that the state will pay in your voucher will not exceed the amount that the state spends per student in the public school.  In my state of Arizona this is 7,608 dollars, in Louisiana it is 10,684 dollars per student.  (Yes, Louisiana outspends my state)  

Combining these two figures together should paint an interesting picture.  If you are poor, having 10k of your child's tuition paid is still not likely to get them into a non-religious private school, instead you are left with the religious schools, some of which are (at least in Louisiana) painfully bad.  On top of that, the statistics gathered on this topic may mislead people into thinking that by merely moving their child to a private school they will fix their performance problems and increase their grades.  Which, as I pointed out earlier, may not be the case.

I am sure that there are solutions to the current education woes in our country, but they will not be as simple as moving students to private schools.  Doubly so when you consider that the voucher programs are often a thinly veiled way for fundamentalist Christians violate church state separation, by pushing inaccurate and biased versions of science, and history on U.S. children.  Thanks to people like Don McLeroy we already have enough of that to fight in the public school system, but at least we have the ability to fight it there.
