The first question is about religion in general. “There is little truth in any religion — there are basic truths in all religions — there is most truth in only one religion” For physics the number was 33/64/3. Chemistry 23/74/3. Biology 28/69/3. Sociology 22/26/2. Economics 30/67/3. Political science 15/77/9. Psychology 25/75/1. (Note I rounded to the nearest percent. The number of significant digits used in the paper seems non-sensical)

The next question was about God. There were lots of answers. I’ll just list the numbers for atheism, belief in God with doubts, and knowing there is a God. The agnostic numbers as one might expect are higher. Physics 41/13/6. Chemistry 27/18/11. Biology 41/10/7. Sociology 34/12/9. Economics 32/15/10. Political science 27/22/9. Psychology 33/13/11.

I think this shows that in the hard sciences while there’s some loose religious belief at higher numbers than one might suspect a strong commitment to a particular religion is uncommon. You can see this in the religious attendance figures for instance. You have around 15% who regularly attend services (once a month or more) Again this isn’t representative of PhDs but professors.

According to 2015 Gallup data, Hong Kong’s population was 34% atheist. I’m not sure how many are agnostic or non-practicing.

The Hong Kong Government Affairs Bureau claims that there is over 1 million Buddhists, over 1 million Daoists, 500K Protestants, 400K Catholics, and 300K Muslims. Additionally many follow Confucian traditions. Right there that is over half the population of Hong Kong. Demographers sometimes group practitioners Chinese traditional religion with irreligious, which is highly misleading. The fact of the matter is that many of the Asian religions are not focused around belief in specific deities, but are more about being in tune with the cosmos and leading a balanced lifestyle. One who deeply reveres the philosophies of Confucius could be considered both atheist and religious at the same time.

I am just disappointed that notwithstanding scientifically informed folks who are religious (and find that there is nothing that conflicts between the two), there are strains of religions that eschew scientific understanding due to the perception of that conflict.

“• Belief in a Higher Power is especially high among scientists in Turkey, India and Taiwan. (The category “at least some belief in a Higher Power” combines several groups, including those with and without doubt about the existence of God, those who believe in one or many gods, and belief in a Higher Power.)
• A majority of scientists in Turkey, India, Taiwan, Italy, and Hong Kong believe in one God, many gods, or a Higher Power.
• Only in France do a majority of scientists identify as atheist.
• Agnosticism among scientists is highest in the U.S. at 29 percent, followed by the U.K. at 25 percent.
• A majority of scientists consider themselves either religious or spiritual, or both, in all regions except the U.S., U.K., and France.
• More than 50 percent of scientists in the U.S., U.K., and France consider themselves neither religious nor spiritual, with French scientists scoring highest on this measure.
• India and Turkey show the highest prevalence of scientists who consider themselves “religious, but not spiritual.” Follow-up interviews revealed that discourse surrounding the term “spirituality” is less elaborate and not always tied to religion among scientists in India and Turkey, relative to other regional contexts. Taiwan is the only country in which the most common identification among scientists was “spiritual, but not religious.” ”

There is also data on attendance at religious services, and prayer practices.

From the conclusions of that report:
“In the United States—which has a high level of Christian faith as well as religious diversity—we find more conflict between science and religion than in the other countries studied because there is a culture of passive secularism and greater leeway for the display of religion (particularly among evangelicals and Catholics). Some groups of evangelical Christians, in particular, have been vocal in their opposition of human embryonic stem cell research and the teaching of evolution in public schools. U.S. scientists are much less religious than the general population, and the difference in religiosity is more pronounced here than in other countries, such as the U.K. and India, leading potentially to more of a conflict framing for the relationship between religion and science.”
As I recall this was the point I was trying to make to another commenter on a post here a few years back just as this study was in it’s infancy. It’s nice to see the data back up my anecdotal experience.

“The study’s results challenge longstanding assumptions about the science-faith interface. …. The researchers did find that scientists are generally less religious than a given general population. However, there were exceptions to this: 39 percent of scientists in Hong Kong identify as religious compared with 20 percent of the general population of Hong Kong, and 54 percent of scientists in Taiwan identify as religious compared with 44 percent of the general population of Taiwan. Ecklund noted that such patterns challenge longstanding assumptions about the irreligious character of scientists around the world. …. “Science is a global endeavor,” Ecklund said. “And as long as science is global, then we need to recognize that the borders between science and religion are more permeable than most people think.” ” https://phys.org/news/2015-12-worldwide-survey-religion-science-scientists.html
