The Secret Social Power of Small Talk
Many conversations are not about sharing information at all. We use phatic expressions like how are you to build social bonds, signaling that we are friendly and willing to communicate rather than exchanging facts.
When someone asks how you are, they usually do not expect a detailed medical report. These phrases act as social glue that keeps relationships smooth and predictable. By following these polite scripts, we confirm our membership in a community without needing to say anything deep. It is a brilliant way to maintain human connections with almost zero mental effort.
