We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
"Cooperation" has been the mantra of the Kindergarten-minded in our midst for years. "Competition" is supposedly male, leads to Capitalism and war and other not-nice things, and is thus evil and a human trait which must be eliminated.
Of course, I have never noticed women to be any less competitive than men. Everybody enjoys a bit of the spice of competition in life, even when you lose.
Interesting article. Given that I have a natural bent towards math and stats I'm probably not the best person to comment, but I can't help but wonder at the educational levels of the test subjects. As soon as I saw the experiment parameters, the solution to "win" the most coins immediately became apparent. Anybody who had taken a basic logic course or game/set theory course would have seen the advantages quickly.
With respect to men being competitive, I can state, merely by observation having raised two daughters and watching my lovely bride work within the largely female world of elementary school education, that women compete just as intensely as men only they compete in a constantly changing landscape of defensive and offensive personal and political alignments of "us" against "them". A very different kind of competition, but competition none-the-less.
