I'm stuck. Like, I can't get a read on much of him. J-wise, he seems quite on-beat and engaged emotionally with his audience, showing concern that they're engaging with his points. But he also seems nasal and snippy. At one point I was sure he's Fe/Ti, but then I switched to Te/Fi. I think I'd go with Te/Fi, and I think he's just a 'good' communicator. I also can't tell his P. Ni maybe? TeNi?
I suppose there are a few things I could say he's not (I think). He's probably not Ji or Pe lead. I think. He's not extremely introverted, I think it's safe to say.
Yeah, I'm definitely thinking Te-lead now. I think I was initially thrown by his pinching and on-beat concern, but underlyingly he's snippy and avalanching, and nasal. I think 'on-beat' isn't totally natural for him, he'd like to get his thoughts out quicker than his body articulations allow, but he's a teacher and communicator. I'm still open to other thoughts though. And I still think Ni is his secondary, but less sure. I think it's just that his eyes have a 'happy-hypnotic' effect, and not Si concern or slanting edges.
He actually really reminds me of Melinda Myers, which is probably seems like a random association, but anyway, I'd kinda typed her a while ago as probably TeNi, and only realised after watching a few Sean Carroll videos that he was reminding me of someone and it was Myers.
