What percentage of scientists don't believe in God... and why?

Answer 1

I don't know how accurate the statistical research is, but my own impression (NOT scientific) is that the percentage is quite high. And that makes sense, because belief in God requires "faith," a concept which is anathema to scientific thinking. Faith is basically belief in the absence of evidence, or even in the face of evidence to the contrary. Such a style simply will not work for scientists.

Answer 2

A study has shown atheism to be particularly prevalent among scientists, a tendency already quite marked at the beginning of the 20th century, developing into a dominant one during the course of the century. In 1914, James H. Leuba found that 58% of 1,000 randomly selected U.S. natural scientists expressed "disbelief or doubt in the existence of God" (defined as a personal God which interacts directly with human beings). The same study, repeated in 1996, gave a similar percentage of 60.7%; this number is 93% among the members of the National Academy of Sciences. Expressions of positive disbelief rose from 52% to 72%.

This is either because scientists have pulled back the curtains where God used to hide, or inquisitive minds, who are unsatisfied with "God did it" answers, are more likely to become scientists.

Answer 3

According to the National Academy of Sciences, 91% of their members do not believe in God. Why? Because they are scientists.
