Mind Cafe is a Medium publication of self-improvement pieces on habits, stress, books, productivity and psychology.
HN links it rarely; the one comment shares its essay on the laws of human stupidity without giving an opinion of the blog.
The probability that a certain person is stupid is independent of any other characteristic of that person.
