Fitting in

From Ars Technica:

Fitting in to a group without helping the group: We've all met the sorts of people who adjust their behavior to fit in better with a group. And now a study has come along that confirms our worst suspicions about them: they don't actually care about the wellbeing of the group they're trying to fit in to. Some researchers from the University of East Anglia set up a public goods game, where participants could contribute some resources so that the entire group would benefit. Those that valued being accepted by the group the most were less likely to share resources for said group's benefit. The highest contributions came from those who had the lowest interest in being socially desirable, but only under specific circumstances: the experimenter had to praise their previous contributions to get them to cough up more.

Interesting. I don't think it's related to introversion. It seems that people who are less interested in fitting in would be willing to contribute more if they were praised compared to people who aren't that interested in the well-being of the group in the first place.
