The GPA vs Income thing is not really the interesting thing in this article. The REALLY interesting thing was that there was no corresponding benefit for women who joined sororities. The author kind of hand-waved over this with statements such as: > One reason for this may be that women are more likely to form social bonds with other women outside of these structures. Which honestly doesn't make a ton of sense. If they're saying that the bonds formed in sororities are less intense than those of fraternities b/c women socialize outside them, they really need something to back that claim up. The few women I know who did join sororities were very much dedicated to their "sisters" and it pretty much controlled their social life. If they're saying that men need same-sex friendships to get positive career effects, and that women are more likely to already get those with or without a sorority, that's also not logical. Especially if you consider they studied the impact of fraternities over a time that includes dates from when the college was men-only and claim the fraternity effect was consistent. If "same sex social bonds" was really the driving factor, then men from non-fraternities should have seen the same effect back when the school was single-sex, since all of them would have more (and nearly exclusively) same-sex friendships. Their other reasoning is: > sororities hadn’t been around for long enough to provide the same networking opportunities as the more established fraternities at the former men's college he and his co-authors studied. This one seems easy to falsify as well. Simply compare the salary outcomes from men in newer / less-established fraternities (I assume those pop up from time to time?) to those in older ones, and compare both of those to sororities with age of organization considered to see the difference. If age of fraternity is irrelevant, then it should be irrelevant to sororities as well. I'm of the opinion that fraternities are a good way to make connections with people who don't mind doing favors for other fraternity members, including hiring/promoting/vouching for them over non-members for jobs. Since women are less likely to be in positions of power where they can do "favors' like that in the first place, and because studies show that women are judged more harshly for promoting diversity (aka hiring other women - see: https://hbr.org/2016/03/women-and-minorities-are-penalized-for-promoting-diversity https://hbr.org/2016/03/women-and-minorities-are-penalized-f...) there is less opportunity or incentive to use those connections to give career favors to sorority sisters.
