One problem with this question that that although we have a
cliched mental picture of the job description "scientist", the
actual real world spectrum is rather wide. Many people can
fairly be called "scientists" who work in very narrow fields,
and are never come across any issues in their field that are
really relevant at all to the question of god, or religious
belief.
Now, in theory, all scientists should know how to think
critically, and in fact must do so at very least on the subjects
they work with, otherwise they wouldn't be very good at their
job. However, just because someone is capable of thinking
critically about one subject does not translate into thinking
critically about other things, especially when those things
are insulated by tradition and emotion and family, AND don't
have a relevant negitive effect on thier actual work.
Also, something interesting happens when you break up
the polling to look at "eminent" or "leading" scientist.
(i.e., scientists that are most productive and prolific and
published)
from: Leading scientists still reject God
the question of religious belief among US scientists has been debated since early in the century. Our latest survey finds that, among the top natural scientists, disbelief is greater than ever — almost total.
In 1996, we repeated Leuba's 1914 survey and reported our results in Nature [3] . We found little change from 1914 for American scientists generally, with 60.7% expressing disbelief or doubt. This year, we closely imitated the second phase of Leuba's 1914 survey to gauge belief among "greater" scientists, and find the rate of belief lower than ever — a mere 7% of respondents.
Leuba attributed the higher level of disbelief and doubt among "greater" scientists to their "superior knowledge, understanding, and experience" [3] . Similarly, Oxford University scientist Peter Atkins commented on our 1996 survey, "You clearly can be a scientist and have religious beliefs. But I don't think you can be a real scientist in the deepest sense of the word because they are such alien categories of knowledge." [4] Such comments led us to repeat the second phase of Leuba's study for an up-to-date comparison of the religious beliefs of "greater" and "lesser" scientists.
Our chosen group of "greater" scientists were members of the National Academy of Sciences (NAS). Our survey found near universal rejection of the transcendent by NAS natural scientists. Disbelief in God and immortality among NAS biological scientists was 65.2% and 69.0%, respectively, and among NAS physical scientists it was 79.0% and 76.3%. Most of the rest were agnostics on both issues, with few believers.
Feel free to take issue with their definition of "greater" scientists, and I suppose all this shows
is that the more "successful" and prominent you are in the science world, the less likely you are
to believe in god, and I suppose you could argue that this is because the leading scientific
establishment has a bias toward atheism, thus giving preferential treatment to such scientists,
but that is a moot point considering that the opinion of the scientific community is exactly what
we are talking about here, for whatever that it worth.
The point is, the deeper and higher you get into the sciences, the less likely you are to believe
in god and the supernatural.
