I wonder if it has to do with extreme introversion.
For example, I think my mother doesn't understand the dynamics of some shows. There's a show in here, where there are people collaborating and speaking, and sometimes, the host tells them to do something crazy, like singing, for example, or those things. My mother says that's derogatory and laughing to people. I can't understand it, because I see they work there, and they are there doing this because they want, and they are not poor people that will sell their lives for a cent, you know? And even although they sing bad and everyone laughs, I don't see it derogatory; it's like when you go to a karaoke.
Is my mother simply moronic and uptight or this has a justification in MBTI?
