ELI5: Why do we laugh at things when with a peer that we would not even find amusing alone?

It's a bonding mechanism. A lot of laughter can be attributed to bonding with others:

- when people are in a group and laugh, they tend to look at the person they feel closest to or would like to feel close to

- in dating, humor is big factor for how well 2 people connect.


You tend to feel close to those who laugh with you for the same reasons.
