"Maupin and her colleagues focused on a cohort of MBA students to conduct their study." I don't know how much this group tells us. When I was in business school most of the group projects were things I could do on my own if I had to. So compatibility was an absolute gating requirement, you didn't want anybody who could screw up the whole thing. And business school competence was mostly a matter of applying yourself, it wasn't as if there were wide differences in basic ability. I would probably weight compatibility differently if I was truly dependent on their input, and if that input varied a lot among possible members.
