That line doesn't really match with men being asked to try equally hard.
It seems to me that academic and professional societies are desparate to hit a 50/50 balance in new inductees, but they are finding that there is a paucity of qualified candidates due to upstream issues. (Remember that the current crop of peak career researchers started their training in the 80s and 90s, when the gender split among new trainees in the sciences skewed heavily male and when DEI programs for early career researchers did not exist nearly to the extent that they do now.)
But if you admit a class of inductees that's 80% men and 20% women in this day and age, it's very difficult to explain in a way that doesn't put you in a hot seat. It's much easier to apply asymmetric standards until you get a neat 50/50 split (or at least something close) because this is less likely to raise questions. So that's what the societies do.
