All right. New here, so bear with me if I breech some kind of protocol or etiquette.

So adding some sciencytechy stuff which is also moderately politically uncorrect: I hear much complaining about gender bias in medicine, and in particular in how medical research overwhelmingly is directed at men and typically male diseases.

Then I find this claiming the exact opposite:

And even this, from 1994:

Assuming these are correct (and they look thorough and easily verified to me), why does everybody have the wrong impression? Is it just because there are strong communities which push the opposite view for ideological reasons? And are people reluctant to contradict them out of fear of shaming, or perhaps out of a sense of chivalry?
