STUDIES Of SCIENTISTS
1. William S. Ament, 1927C. C. Little, president of the University of Michigan, checked persons listed in Who's Who in America: "Unitarians, Episcopalians, Congregationalists, Universalists, and Presbyterians [who are less religious] are¡¦ far more numerous in Who's Who than would be expected on the basis of the population which they form. Baptists, Methodists, and Catholics are distinctly less numerous."
Ament confirmed Little's conclusion. He noted that Unitarians, the least religious, were more than 40 times as numerous in Who's Who as in the U.S. population.
2. Lehman and Witty, 1931Identified 1189 scientists found in both Who's Who (1927) and American Men of Science (1927). Only 25 percent of those listed in the latter and 50 percent of those in the former reported their religious denomination, despite the specific request to do so, under the heading of "religious denomination (if any)." Well over 90 percent of the general population claims religious affiliation. The figure of 25 percent suggests far less religiosity among scientists.
Unitarians were 81.4 times as numerous among eminent scientists as non-Unitarians.
3. Kelley and Fisk, 1951Found a negative (-.39) correlation between the strength of religious values and research competence. [How these were measured is unknown.]
4. Ann Roe, 1953Interviewed 64 "eminent scientists, nearly all members of the prestigious National Academy of Sciences or the American Philosophical Society. She reported that, while nearly all of them had religious parents and had attended Sunday school, 'now only three of these men are seriously active in church. A few others attend upon occasion, or even give some financial support to a church which they do not attend¡¦ All the others have long since dismissed religion as any guide to them, and the church plays no part in their lives¡¦ A few are militantly atheistic, but most are just not interested.'"
5. Francis Bello, 1954Interviewed or questionnaired 107 nonindustrial scientists under the age of 40 judged by senior colleagues to be outstanding. Of the 87 responses, 45 percent claimed to be "agnostic or atheistic" and an additional 22 percent claimed no religious affiliation. For 20 most eminent, "the proportion who are now a-religious is considerably higher than in the entire survey group."
6. Jack Chambers, 1964Questionnaired 740 US psychologists and chemists. He reported, "The highly creative men¡¦ significantly more often show either no preference for a particular religion or little or no interest in religion." Found that the most eminent psychologists showed 40 percent no preference, 16 percent for the most eminent chemists.
7. Vaughan, Smith, and Sjoberg, 1965Polled 850 US physicists, zoologists, chemical engineers, and geologists listed in American Men of Science (1955) on church membership, and attendance patterns, and belief in afterlife. Of the 642 replies, 38.5 percent did not believe in an afterlife, whereas 31.8 percent did. Belief in immortality was less common among major university staff than among those employed by business, government, or minor universities. The Gallup poll taken about this time showed that two-thirds of the U.S. population believed in an afterlife, so scientists were far less religious than the typical adult.

According to the studies above, yes. I have yet to find a study that indicates otherwise. The higher your IQ the less likely you are to be a believer.
