This study comes to a happy conclusion, and then wrecks it all with EP bullshit. What the researchers did was to email requests for either a pdf of a paper or copies of the raw data to researchers, and what they found was a high degree of cooperativity: 80% were willing to send a pdf, 60% were willing to send data. They seem to think this is surprisingly prosocial, but actually, I was a little surprised the numbers were so low. I was brought up to consider this to be expected — back in my old-timey days, when you published a paper, you also ordered a great big box of reprints, because people would send you postcards asking for a copy, and you’d mail it to them. Now you just push a button on a computer, and only 80% oblige? OK, I guess that’s an alright result.
They analyzed further, though, and also found a sex difference. If you were a man requesting a paper from a man, you were 15% more likely to get a positive response. That’s troubling. I’d say that that could be interpreted as indicating a continuing sexism in science. But that’s not enough for these authors.
There is no evolutionary analysis involved in this study, but of course, the reason for their result is…evolution.
Massen and his colleagues say that one possible explanation for their results “may be that among male academics there is a network at play, in which they favor each other much like ‘Old Boy’ networks”. They also suggest that this imbalance might have evolutionary roots and point to an idea called the male-warrior hypothesis, which states that men have evolved to form strong bonds with other males in their group because in the past this enabled them to defend territory from hostile attackers.
“Men are more ready to cooperate with genetic-stranger males to form these fighting coalitions,” says Mark van Vugt, an evolutionary psychologist at the Free University of Amsterdam who first suggested the theory in 2007. Some of the evidence for this idea comes from lab-based tasks such as public-goods games (in which volunteers choose how many tokens to keep or share), but there are some real-world hints too, he says. Boys tend to play in larger groups than girls, van Vugt says, and in sports such as tennis and boxing, men make more effort to bond with their opponent after a match or fight than women do. However cultural factors are also thought to be at work.
Jebus. Can I just say the words “US Women’s Soccer Team” and see this whole bogus line of reasoning vanish in a spray of flop sweat and tears from the men’s team?
