Like-mindedness. Like. :)
I found this article's bias interesting. Can 'signalling' not be the same as, 'Hey, buddy this is what I am up to', for the same reasons one might do it in real life? I know why I do things, to attract like-minded people - who might hear of a nice project and know they should include me so that I can find more like-minded people. I know I let people know about nice opportunities, and they let me know. The circles grow. And non-like-minded people would wonder, in their silence, if we were taking over the world. When people say the k-word, they're signaling. I know what to do with that signalling. In the age of communication, this kind of bias about signalling is a signal. I know what to do with that signalling. Aeon: https://aeon.co/ideas/is-virtue-signalling-a-perversion-of-morality
