I asked because I am INTP (not sure if -A or -T, only one online test I took went to those alternatives and I just don't recall) and the way you described G's attributes about BS detection and problem solving reminded me of myself.

I am a big believer in MB because my results describe me very well. I am aware that the psychiatric and psychology professions frown on it because it is not based on science, but that doesn't make it any less accurate. They like the "Big 5." My Big 5 results are very congruous with my MB results, except I score as extrovert on the Big 5, but I think that's because I am a not shy introvert and also my MB results of I on the I/E pole are towards the middle of the spectrum.
