Laughter Is Contagious — Literally, and Your Brain Reacts Before You've Decided It's Funny
Hearing laughter activates the smiling regions of your brain before you've consciously judged whether anything is actually funny.
Just hearing a recording of someone laughing is enough to make your facial muscles start arranging themselves into a smile — even if nothing funny actually happened.
It's a result of so-called emotional contagion: the brain has circuits that automatically "try on" someone else's emotional expression before the conscious mind has even had a chance to evaluate the situation.
That's why TV shows have used canned laugh tracks for decades — it's not a naive gimmick, it's exploiting a real neurological mechanism that makes people laugh more often and more loudly.
One more thing: group laughter is contagious even when nobody understands what's actually funny — the sound alone is enough to trigger the reaction.
