Oh my bad, I must've misread it (thought you wanted the definition), and no I can't explain that phenomena you were feeling, I think some users could pitch in and as some of them may have a better grasp of it than me.
This happened to me also when I took the test. It must be because we don't think about these things until we're asked directly, and once we're asked, we don't know the answer. Just a lack of knowledge of oneself.
Connection between being blackpilled (not necessarily incel) and INTP (logician). The blackpill is about objectively looking at society, and INTPs are all about objective fact. I got INTP like other board members.
