We all suffer from numptyism to some degree or another. We've been given an environment in which we are presented with problems/solutions to sort out together. In an environment where anonymity gives us a freedom to exercise our higher thought processes without peripheral judgements that tend to shape our opinions to a degree. That environment also tends to lower the volume in an emotionally charged exchange, in a way that allows private contemplation of others opinions and perspectives. In short,...Iron sharpens Iron.
