If someone told you to act in a way that you knew would hurt another person, would you do it? No? Absolutely sure about that, are you? Th ink about it. If a recognised authority figure told you to push a button, which you knew would deliver a mild electric shock to another person every time they made a mistake, would you? You might do that, right? I know I probably would. But, if that same authority figure told you to push a diff erent button which they said would severely shock – and perhaps even kill – the person, would you do it then? Absolutely not, you say? Me neither. No one would ever knowingly do something as perverse as that, would they?
