You didn't even provide an example. I'd imagine it's mostly nervous laughter when you say something completely retarded as you did just now, and they have no other response.

over exuberance is selected for socially.

Nervous laughter is annoying

Also, I am an American. I've seen a million examples.

I know in California tech industry, we laugh to the bank because you buy our shit.

Because they think it fools people into thinking they're outgoing and vivacious and not secretly miserable inside. The problem is that since most people do this same thing for these same reasons, absolutely no one buys it. The only thing keeping this charade from falling apart is that it's impolite to point out to people how plainly insincere and full of shit they are.

To get attention.

Good answer
