Why do people subscribe into the idea that there are these temperaments of personality types. The temperaments, (NT;NF;ST;SF) and (EP;EJ;IP;IJ) are just dumb. Take an ENTj and INTj for instance. These two types are going to be extremely different, hell, they are completely the opposite. The only similarity is they both favor the judging-perceiving ordering of functions. Now take ESFps and ENTps; there is very little(if any) similarity between the two types besides that they both use perceiving dominant functions. There are very few trait similarities that you can find besides the two types. I just don't understand why everyone subscribes to the temperament theory.
