“Small talk” is culturally designed to weed out 70-80% of those people who are likely to be dangerous, unstable, or unreliable, allowing us to know who we need to pay close attention to in our environment and who we probably don’t. It’s not a question of “lying” or “telling the truth”, it’s a question of “can you perform your socially expected role in this cultural ritual?”.
I find that the best and worst people are really good at small tall. The best people use small talk to establish relationships and ease into more personal topics that they honestly care about. The worst people use small talk to establish a connection that they can abuse later on.
It doesn’t weed out anything but honest people.
The ability to follow social rituals like small talk, handshakes, bowing, making small offerings, etc. doesn’t screen anything for the people in the middle of the bell curve other than the knowledge of and conformity to social rituals.
What is the benefit of screening people through social rituals?
