What are people’s opinions on socionics?

No, I don't have a very positive attitude towards socionics. Although its predictions are often accurate, I don't like the idea of classifying people based on their psychological traits. I feel the same way about horoscopes. Of course, every person is unique, but I'm also not a fervent advocate for individuality. But choosing friends and loved ones based on questionnaires – like, according to this test, this person is like this, so I'll be friends with him, but that person has a different trait, so I won't be friends with him because he's incompatible with my character – isn't particularly appealing. This is my subjective opinion, i.e., my personal opinion, i.e., IMHO.
