Let’s frame this sort of difference more mechanically. Suppose you have an electrical cord that plugs into a socket; when it’s plugged in, you don’t steal. The socket is made of an imaginary protein that comes in two variants, which determine how wide the slots are that the plug plugs into. In a silent, hermetically sealed room, a plug remains in the socket, regardless of variant. But if a group of taunting, peer-pressuring elephants thunders past, the plug is ten times more likely to vibrate out of the loose-slot socket than the tight one.
