Would you keep harming a stranger just because someone in charge told you to?
Two out of three ordinary people will push a button they think is killing someone, as long as a calm authority says to keep going.
In Stanley Milgram's experiment, volunteers were told by an experimenter to give a stranger stronger and stronger electric shocks for wrong answers. The shocks were fake, but the volunteers did not know that. Even as the stranger screamed and then went silent, 65% obeyed all the way to the final 450-volt switch - not because they were cruel, but because a credible authority kept calmly saying the experiment must continue.
A new staff member keeps charging a customer a fee they suspect is wrong, because the manager said do it and the manager is the one who answers for it.
An authority that takes the blame can pull normal people into harm they would never choose alone.
When an order feels wrong, the safe move is to ask who is responsible and to make the harm to a real person visible again.
Milgram = the calm voice says continue, and the finger keeps pressing.
