Of course I was oversimplifying :) In any case, that study removes many of the reasons that groups of humans make bad decisions - which is unfortunately impossible to do in most real-world contexts. If you want to be more precise, we often make assumptions of people belonging to a group that is not our own. The safest assumption to make is that all other groups are dumb. Ironically, this likely reinforces the problem: Why is this other group assuming our application doesn't have feature XYZ? Of course it does, because we're good at what we do. But obviously they must not be very bright to make such an assumption...
