I noticed on Saturday while talking with a good teacher, that I play something like Devil's Advocate pretty often. This happens specifically when discussing about things I have given a good enough thought but I have still been unable to form confident conclusion about any particular side.
I think this practice is helpful in the sense that it allows one to explore various points in the explanation-space of a specific problem or phenomenon in order to ultimately find out which point in that complex space is closer to the truth.
