odd
Odd conclusions (although not unexpected from the psychological establishment)
two points:
1. IQ is probably the worst method of measuring intelligence given the majority of questions are not based around learning aptitude or reasoning, but already learned knowledge.
2. In my experience of the scientific community in general, (not just academics) my friends cover quantum physics, biology, chemistry, Rural science, Entomology, computer science, mathematics, . These range from full-blown PHD's down to Masters levels, most are published. Amongst these people, the proportion of people who believe in a God or something of that nature, is substationally higher than the rest of the population.
In fact if you look at major innovators and scientists of times past, you will find the majority who made major breakthroughs actually believed (or at least stated they did) in a god.
3. A problem with surveys is that often only those who feel strongly about something will fill them out. if a survey system was used here the results are already skewed.
