Why do people sometimes conform to group opinions they disagree with?

People sometimes agree with what most people think even if they don't really like it, kind of like when you're at a party and everyone is cheering for the same team, but you secretly want the other one to win.

Groups can feel powerful. When a lot of people are shouting or laughing about something, it's hard not to join in. It’s like being on a playground swing, if your friends all jump off at once, you might feel like you should too, even if you're not sure you want to.

Your brain likes things to be simple. If everyone around you thinks something is fun or right, it can feel easier just to go along than to stand out and think for yourself. It’s a little bit like when you’re playing tag, sometimes it's more fun to be “it” if all your friends are in on the game.

Sometimes people even change their mind because they want to fit in better with others, kind of like how you might wear your favorite shirt to school just so everyone knows you're part of the group.
