Practitioners of MBTI and Socionics can spend as much time as they like "describing" their systems, but my view is that they likely have at least a moderately high level of correlation with each other, as commonly perceived by users. I also think they likely have at least a moderately high level of correlation with the Big Five (aside from Neuroticism). Too little time here is spent on making observations, and too much time on trying to explain anecdotes.
