@nikipedia Are you saying the total study had only 197 subjects? Or, did I misunderstand? That is not a very big sampling of people.
Were you able to see the questionaire that was used? I would be curious to see it. In college I participated in a study. About 10 of us at a time showed up and took a questionaire asking questions about religious beliefs, study habits, performance in school, and happiness if I remember correctly. During the exam I asked what we should do if none of the multiple choice answers fit what I would answer. He said to just pick the one that best fit, not to skip a question.
When I stood up to give my paper to the person overseeing the group, he was busy with something so I waited a minute; by the time he was free for me to tell him something another student, who was in my group, was waiting with me. I handed him the paper I had filled out, one of those number two pencil bubble things, and said, “I really don’t know if my answers will be helpful or valid, it was very difficult for me to answer the questions, many times there was no answer that fit me. It seemed to me it was written by and for Christians, and I am Jewish and not religious. The girl next to me said, “I am Jewish also and I had the same problem.” Seems she had been waiting to tell him the same thing. He said it shouldn’t matter what religion we are because they are only trying to draw conclusions measuring if people who have a strong belief structure do better academically and some otehr measures. I still hold that the questions they asked do not give the correct conclusions.
I know I was not represented correctly on the bubble sheet, I think the majority of Jews are similar to me in my beliefs, and we know statistically Jews do well in education, a significant percentage of Jews are Atheists, but I think that questionaire would conclude a different story.
I am not quarreling with your conclusions, or even the study we are talking about, because maybe the questions were done very well. Just making a point about studies. I also lean towards believing atheists probably do score a little higher on IQ as a whole, but I figure it is probably insignificant.
I also, have no idea what types of percentages of people from lower socio-economic situations are atheists compared to higher income? That would be interesting to me. Economics has some bearing on IQ I would think. I do not mean that people with low IQ’s are more likely to be lower class, I mean if you grow up and live in the lower classes you might have less exposure to education and other things that can give opportunity for natural IQ to reach its potential.
