It's amazing that something so sexist could have been suggested without backlash. Imagine if studies indicated that low testosterone limited or in some way hindered another desirable human capability. People have been fired for it and reputations ruined. Suggesting men are emotionally stunted. Oh that's fine.
I mean, you should be able to claim either if you have evidence. We should be looking for truth, not virtue signalling by withholding findings because it might hurt some people's feelings.
An observed fact and problem with behavior science is that they tend to align based on the culture of where the research is taking place. In Germany around 1940 you got very distinct results in behavior science compared to modern views. Behavior research made during the cold war looks very different depending which side of the Berlin wall it came from, even when accounting for sample size and scientific methods.
There are theories that tries to explain this, like for example that researchers tend to focus narrowly on questions that feel relevant in their personal culture, and then drawing larger conclusions.
