Why is Myers Briggs being referenced when it has zero substance to back it up? I thought it was common knowledge that pop psychology stuff was garbage, at least amongst this website’s readers.
Not quite zero substance, the four dimensions are reasonable close to some of the five leading components of personality.
The problem is that each letter comes from splitting a normal distribution in half right at the middle where maximum likelihood is. So most people won't be very strongly attached to most of their letters.
That "common knowledge" is wrong. Myers briggs is not great for scientific studies since it splits people into 16 buckets instead of sliding scales (like the Big 5, which is used in research). But MB is an incredible mental toolkit to have.
