Humour Effect
We remember things better when they make us laugh.
What it means
The humour effect is the finding that humorous information is more easily remembered and recalled than non-humorous information. A joke, a funny example, or an unexpected punchline in the middle of otherwise dry material acts like a memory bookmark - your brain flags it as worth keeping.
This works because humour triggers emotional arousal and engagement. When something makes you laugh, it activates reward centres in the brain and increases dopamine - the same neurotransmitter involved in motivation and memory formation. The emotional charge gives the information extra sticking power, similar to how you remember emotionally intense experiences more vividly than mundane ones.
The humour effect has obvious implications for teaching, public speaking, and communication. The best educators and presenters have always known this instinctively: if you can make someone laugh while you're making a point, they'll remember the point long after they've forgotten the joke. The challenge is that forced or irrelevant humour can backfire, distracting from the message rather than reinforcing it.
In the real world
A health and safety trainer has to explain the importance of wearing hard hats on building sites - a message everyone has heard a hundred times. One trainer delivers the standard facts and statistics. Another opens with a genuinely funny story about a near-miss involving a sandwich dropped from the third floor. A month later, the second group remembers the session - and the message - far better than the first. The humour made the information stick.
The thought to hold onto
Laughter isn't the enemy of learning - it's one of its best allies. The things that make you smile are often the things your brain decides to keep.
