Herd Mentality

Behavioral Discipline

Following the crowd instead of thinking for yourself. The tendency for people to follow and copy what others are doing. In markets, this creates bubbles (everyone buying) and crashes (everyone selling) as people abandon individual analysis for 'safety in numbers.' Example: Everyone on Twitter is buying a meme stock. You buy too, not because of your analysis, but because 'everyone else is doing it.' That's herd mentality - and it usually ends badly for latecomers.
