When you share a joke with someone, there is a sense of connectedness.
This was called joke intimacy by Professor Ted Cohen.
This type of intimacy can be shared with someone you know or with a stranger.
For instance, if you see something funny, you might look around to see if anyone else noticed—you might lock eyes with a stranger, and you both giggle.
You’ve developed joke intimacy through a shared experience of laughter.” Dr. Gimbel
explained, “There is a sort of bond there, that happens with humor, which builds a sense of human community.”
