peer pressure
The influence friends your age have on your choices.
Peer pressure is the influence you feel from people your own age to act, dress, or think a certain way. When your classmates all wear a particular style of shoes and you feel like you should too, that's peer pressure. When friends encourage you to try something you're not sure about, whether it's joining a sport or doing something you know is wrong, you're experiencing peer pressure.
The pressure can be direct, like when someone says, “Come on, everyone's doing it!” or subtle, like noticing that all your friends have the same hobby and feeling left out. Sometimes peer pressure pushes you toward good things: your study group might inspire you to work harder, or your soccer teammates might motivate you to practice more. But it can also push you toward choices you'd normally avoid, like being mean to someone just because your friends are, or pretending to like something you actually don't.
What makes peer pressure tricky is that it often doesn't feel like pressure at all. You might genuinely want to fit in and be part of the group, so you change your behavior without anyone directly telling you to. Recognizing when you're making a choice because you truly want to, versus when you're making it just to match what others are doing, can help you make decisions that feel right to you.
