pretty simple, look how they behave towards others and how they treat their other friends, ever notice someone who tries really hard to put on a show of being nice but then gets grumpy when people don't show them small talk tier politeness back? there's a good chance that person is a skin deep persona who thinks acting like a serial killer still wearing the victims skin in a interrogation is being nice
just observe people and see what makes them tick, what are their carrots, what are they doing, how are they doing it, who are they doing it with, paint a picture of what they are in your head and avoid confirmation bias, only paint what is real and tangible about them, innocent until proven guilty and all that
it's a process where you observe them until you start to see a picture form and the patterns that make that picture are the patterns of them as a being or persona, some people are skin deep persona's those are the easiest to paint
