The social sciences, "science" only in that way that something like military science is, a proper name, are instead in the humanities camp, and overwhelmingly biased against non-progressives, so it is no surprise that censorship, self-censorship, deplatforming, and suppression of anyone who deviates from the majority is common.

Psychology is driven by surveys, most often undergraduates at their school, commonly undergraduates in psychology classes, and if there is budget including people who get paid to take surveys. To the real world the results are 'a social science of undergraduates' and nothing more, so no one takes it too seriously. Except other psychologists.

That self-importance may be why they will call you for to be fired if you deviate from cultural agendas, like that there are fewer women in some fields of science due to anything except sexism. I have written about this a lot. Women are paid as much as men in engineering, within the statistical noise range, while it is actually environmentalism and government (both over 90 percent Democrats) that has the largest pay gaps between women and men. Yes, there are more men than women in engineering and math, just like there are far more women than men in education and psychology.

If you think political conservatives might not be 'self-selecting' out of high-paying jobs for life, you are likely to keep it to yourself.

This is where it gets weird. Men are "self-selecting" out, just like Republicans weirdly are said to not want six-figure jobs where you can never be fired when hiring committees have to account for their prejudice, but women are being blocked. 

It makes no sense, and never did, but what does make sense is that the perception doesn't change. Because asking awkward questions will ruin your chance at tenure, if you are trying to stay at a university, or get you deplatformed by a cabal of social justice warriors who are vigilant against toxic masculinity claims like that differences between men and women involve more than a state of mind.

Barely half of psychologists believe that you should be able to conduct research on social topics without fear of institutional punishment. That means 48 percent of those in psychology think if a psychologist wants to see if there is any truth to the idea that bias may be why there are almost no "conservatives" in psychology, well "it's complicated", which means they may face consequences.

Ten percent said anything they disagree with shouldn't be allowed into publication. What is the crossover number for how many people it takes to create an "icy chill" in any endeavor? Ten percent.

Ross Pomeroy at Real Clear Science and Dr. Jerry Coyne at Why Evolution Is True have the details.
