I can’t even see the title of the original paper since this one is paywalled. I was going to go try to quantify this “absence of backlash” you mentioned.
¹ It is sort of an interesting question, which majority of feminists that is. Some liberal, trans-inclusive, biological-constructivist feminists who believe in a notion of a “female brain” would potentially see no problem with the study. That is quite a minority though. The vast majority of liberal feminists would be “social constructivist” feminists who believe male/female brain differences are overblown and would view the study incredulously. Similarly, some biological-essentialist radical feminists do believe in comprehensive sex differences, and would be amenable to the finding. These would be your typical “man haters”, who are vocal online because their ideas are not welcome hardly anywhere. However, the vast majority of radical feminists believe the male/female sex differences have primarily to do with reproductive organs and, again, brain differences are overblown. And therefore would also be incredulous of the result. So all-in-all the vast majority of feminists would by default object to the study. But there is a sex-essentialist slice that cuts across the liberal/radical divide who would entertain the ideas.
On the MRA side too I believe there are sex essentialists who would be fine with the study, although many more liberal MRAs would object to it purely on the grounds of it portraying men in a negative light. I’m less familiar with the ideological divisions in that group though.
As a side note, this is part of why liberal and radical feminists are able to hate each other and talk past each other: both sides can credibly accuse the other of harboring biological essentialists.
