Most people are unable to laugh on command.

Laughter is an interesting thing—it’s part of a universal human language that all people understand. It’s such a natural response that we often don’t even realize we’re doing it. People have many different types of chuckles and many different reasons for their laughter.

One thing is common though—most people cannot laugh on command. If they do laugh, it is forced and often inauthentic. It will take a few minutes to come up with an actual laugh. This suggests that we can’t deliberately activate the brain’s mechanisms for affective expression.
