      I think that's very true. Of course, I'm not sure that we have a good
      solution for dealing with that at a higher level. Promiscuous pairing
      helps me past problems of irrationally liking my module better than my
      colleague's. But once a group has reached convergence, I think we're
      still prone to the kind of effects that the study demonstrate.

      In some ways, I think it's less of a problem, as hopping around to
      different parts of the code base means we can often come to things with
      fresh perspectives. But in another aspect, I think it's more: if it's my
      whole team that has converged on a solution we like, I will have a lot
      more confidence in it and fondness for it than when I'm working alone.
      In some ways it feels a little tribal to me. Which is good, but not an
      unmixed good.
