So, it sounds like they proved that, if given absolutely no other information by which to judge others, and needing to join up in a group with absolutely nothing at stake, they join up with people of similar attractiveness. Which, you know, sure, but that doesn't really seem like it tells us much. If they had to join together in small groups to perform some task together, it might have been a little more interesting. It also would have been more interesting if we had been given some measure of the correlation between the rated attractiveness and the propensity to join the same group. I mean, for all we know, this could just mean that the people doing the attractiveness ratings gave anyone non-Anglo a low score, and that the students tended to join up more often than not with members of the same race. Or, they tended to rate women as more attractive than men, and the students tended to clump up in same-sex groups. I'm not saying that's what actually happened, but you can't tell from this article.
