...would you do so?
Cliche question but that's what Si is for, asking questions everyone else has already asked and two steps behind.
Personally I would, with the only large downside being that I would not have known some of the people I've met here who I have found enjoyable and who have taught me some interesting perspectives and insights.
However given my MBTI cognitive bent, I generally find the theory unhelpful for my own purposes, that of understanding myself better. Although perhaps that is a bad motive for engaging in typology theories. As for understanding others, I truly doubt it can be achieved, we can only slide ever so slightly closer to the truth trammeled at the heart of that individual, but we will never be them and they never us.
And typology only confounds this in my mind, a nonsense of information with grounds in nothing but experiential observation, which has validity, but not much.
It has taught me new angles of hate and lying and the admiration of a mirror; which in it's insubstantial nature beckons, but without promise of answer....only blind hope and wishful thinking.
I want to believe, but that requires faith and I have none, instead I want proof but proof denies faith and so the theory is useless.
