How much longer before we hit a tipping point?

The article could be paywalled so here's the important part:

In the last several months alone, multiple controversies involving academic censorship have emerged. Earlier this year, a paper by Theodore Hill, a professor emeritus of mathematics at the Georgia Institute of Technology, wrote about the “greater male variability hypothesis,” which posits that men are more variable than women along a number of traits, including intelligence, translating to a greater number of men at the high and low extremes.

After the paper was accepted in one journal and subsequently rescinded due to feminist scholars’ fears that it would be used to justify sexism, Dr. Hill got the paper published in another journal online, only to have it disappear from its website shortly thereafter. He was told the decision was not due to the paper’s scientific methods but its political implications.

In August, another controversy erupted when PLOS ONE published a study by physician Lisa Littman. She wrote about rapid-onset gender dysphoria, a growing phenomenon of girls who, out of the blue, announce they are transgender. Due to backlash from transgender activists, Brown University pulled the study’s corresponding press release, and PLOS ONE said the study had been placed under review. Considering that it underwent peer review prior to being published and other experts in the field would have scrutinized it for its methodology and content, the decision was unheard of.

With academics avoiding entire areas of research as a result, knowledge currently being produced is constrained, replaced by beliefs that are pleasant-sounding but biased, or downright nonsensical. The recent “grievance studies” investigation, led by academics Peter Boghossian, James Lindsay and Helen Pluckrose, laid bare how bad the problem has become. The trio managed to get seven fake papers – ranging from topics like rape culture in dog parks to straight men using phallic sex toys to increase their feminist attitudes – accepted in high-ranking humanities journals.
