Broken escalator phenomenon

Broken escalator phenomenon is when a group of people all stand still on an escalator that is still moving instead of walking up the stairs like they're supposed to. It's like if everyone got stuck in one spot and nobody was moving up the stairs. The reason this happens is because people are used to seeing escalators stay still and when they see one that's moving, it kind of throws them off because it looks like it's broken. So instead of walking up the stairs, people stand still because they don't know what to do - kind of like if you can't figure out a puzzle, you just stay still. That's why it's called the broken escalator phenomenon.
