I find four faults in what a study like this sets to achieve.
1 - It is an
Appeal to Authority. This is because it tries to show that the position of the more intelligent person (since they are reckoned to have greater knowledge) is more accurate or true. The source of a claim such as the disbelief in God has no bearing on it's accuracy.
Not true. Did you even read the article you linked?
Wikipedia said:
argument by authority is a type of argument in logic, consisting on basing the truth value of an assertion on the authority, knowledge or position of the person asserting
The truth value of the conclusion of said study is presumably on data gleaned from application of the scientific method (e.g. the use of IQ testing, which, for all its flaws, is not sentient with its own agenda),
not an authority, entity or person.
The study likely elucidates patterns in IQ scores among social groups. It is no more or less inherently biased than any other scientific study, and it is fully possible for one to strictly and unbiasedly follow the scientific method and
still arrive at the conclusion that those who are a religious have, on average, lower IQ scores.
I am not defending said conclusion, because I haven't seen the study. But your attempt to discredit the study off-hand because it offends your sensibilities is rather cheap.
2 - It is an
Ad hominem argument in that it discredits a claim by attacking it's source. Again this is similar to the above in that it has no bearing on the accuracy of the claim. The intelligence of a person (or lack thereof) has no bearing upon any claim they make about the existence of God.
Again, I highly doubt the study in question makes any such judgement or attack on people of faith. Stating a statistical fact is not an implication of judgement.
There's plenty enough evidence out there of the non-existence of god, without recourse the need to resort to attacks on one's nature, in my opinion.
And that's all assuming that its worth arguing about. It might not have occured to you, but it's generally the religious who feel the need to prove/enforce the existence of God. The casual atheist may certainly find entertainment from trolling a person of faith, but questions about the existence of god actually occupy so little of their time (once they've gotten over the initial depression/glee of this finding); among atheists it is generally accepted that religion and god are silly social notions that for some reason just refuse to die, on par with things like ghosts, and with just as much evidence and logic.
3 - Studies such as these usually only asses forms of knowledge such as IQ which can be easily tested for. It does nothing to address other forms of knowledge such as social interaction, psychology etc.
Is it a problem that something is easy to test? And since when were IQ, psychology and "social interaction" forms of knowledge?
The IQ test is nothing to do with knowledge.
I think I get what you're saying, and I agree to a point. IQ is somewhat one-dimensional in its assessment (it only tests communication skills, spatial skills, abstract thinking skills). Iit fails to consider 'emotional intelligence' (as much as it annoys me to use that phrase), among other things.
Still, as far as aptitude tests go, the IQ test is somewhat useful. For example, if this study is correct, it clearly demonstrates some inherent problems with religious indoctrination (most likely in the home environment); likely sacrificing a child's abstract thinking and capability to adapt to new ideas, in favour of strict adherence to rigid dogma (which I often find to be the case when I am talking to the devout religious).
4 - The area's in which people are educated would also have bearing upon their beliefs. ie those going to university are more likely to have non-religious or skeptical views since there is a culture that promotes such a mindset - regardless or not whether this is because of intelligence. So currently it would seem that the further you delve into eduction the less you will find religious culture. Any attempt to assert that this is because of higher intelligence should be guided back to points (1) and (2) because even if that were true the study would still hold no relevance to the argument against or for the existence of God.
Come again? Sorry, why was it that those going to university are more likely not to be religious?
Still, I highly doubt that if you applied the methodology of such a study to the Australian population that you'd come to such a conclusion. Australian religious adherence is marked by overall apathy and laziness, which to me doesn't seem like an ideal environment for an IQ gap to grow. To me, it'd require religious fundamentalism, such as in any Muslim country, or in the Bible Belt of America.
You're somewhat correct in saying that this has no bearing on the existence of God. But then, at some point we do need to say "that idea is fundamentally just silly" and give up on it. The fact that the group of people who don't believe in an idea are extremely smart and knowledgeable may not be proof of the incorrectness of the idea, but it sure should start to ring alarm bells when mass independent peer review by such people doesn't paint it in a positive light.
