Peak–end rule

Okay kiddo, so have you ever been to a really fun party or played a really cool game and even though some parts were kind of boring or not so great, you still had a good time overall? That's kind of what the peak-end rule is all about!

The peak-end rule is a way that our brains remember experiences, like going somewhere or doing something. It says that we tend to remember the high points (the "peaks") and the end of the experience more than anything else.

So let's say you go to a theme park for the day. You might go on a few rides that are just okay, but then you go on one that's super exciting and you feel like you're flying through the air. That part would be a "peak." Then at the end of the day, maybe you get a really yummy ice cream cone or see an amazing fireworks show. That's the "end." Your brain is more likely to remember those things than the parts that were just okay or sort of forgettable.

The peak-end rule can apply to all kinds of experiences, not just fun things like theme parks. Even if you go to the dentist and it's a little bit scary or uncomfortable, if the dentist is really nice to you at the end and gives you a sticker or a toy or something, your brain will remember that part more than the scary parts!

So basically, the peak-end rule says that the things we remember most from an experience are the best part ("peak") and how it ended ("end"). It's like a highlight reel of our memories!
