Is There a Better Diagnosis for Politicians?

i've been talking about it a few times since, as people have said to me, how could we get a better diagnosis for politicians? How could we actually figure this out? And there's been some efforts to sort of diagnose it through observational data o how they how they talk. But what i suggest is that the new york times are one of these outlets that does a interviews for presidential candidates. If you don't take it, we'll just let the voters know that you didn't take it. Cause i like the idea of a norm being established,. It's not required, but if you're not willing to submit yourself to a psychopath test, that's sort of a worrying thing
