Yeah, I strongly disagree. It’s a genuinely valid way to figure out someone better. While the tests and all that aren’t really standardized, the idea is quite clear, and the idea works. Just because it was made mainstream, does not mean it’s suddenly bad. Just because the origins are sketchy, does not mean the theory is invalid. It just essentially means one’s ability to objectively assess your own and other’s emotions, feel empathy (not just understand it, but feel it), low emotional intelligence people would be less rational about their own and everyone’s else’s emotions. You simply cannot argue against this. It’s a skill/mechanism that makes society function better.
