I have a feeling we by now have way too much "tell something about the mentality" things. People seek most minute and irrelevant details about somebody's life and blow them up into the whole narrative about how it reveals the darkest depths of somebody's psychology, all while ignoring the open history of behavior, speech, accomplishments and so on. The idea that all the observable behavior is just a facade and only this one or two particular details about something that was said or done once 20 years ago reveals somebody's "true character" is bewildering in its irrationality, and still seems to be widely popular.
