Ah, the guy behind less wrong. In order of certainty. Te/Fi Oscillation
Perception I'm torn.
Wanting to say (PiTe)
On the topics of morality this was one of the first guys I ran into that really reflected a lot of what I thought. I remember reading the Harry Potter fanfiction he wrote. Also, I don't remember where, he talked a lot about this worldview where he promises himself that he would never , look away, from the horrors of the world. He seemed very determined in that aspect.
Yudkowsky is definitely Delta. Reminds me a lot of my brother-in-law, actually, who is either FiNe-Te or SiTe. FiNe seems right. Besides the vultology, his speech is really affected (though not airy), and in the second video especially he shows how his thought process is geared toward making Fi ethics judgments.
I'm listening to Sam Harris' podcast with Eliezer (I didn't know who he was before). His voice struck me as very Te/Fi - nasal, staccato (in contrast with Sam's slow, 'kneading out thoughts' cadence), matter of fact. Just thought I'd throw that in there. No idea what his P is from his voice/thoughts, but he hasn't lost me like some heavy Ni types do.
