The experiment was repeated recently, but the volunteers weren't kinder, they were actually more ruthless. This time 75 per cent gave the maximum shock - three times.
What this extraordinary experiment shows is that when it comes to the crunch, people are more likely to be obedient and conformist than to challenge authority and help someone in distress.
However guilty and nasty they felt about being cruel, they were scared to simply refuse and walk out. They somehow justified the instructions, repressed their finer feelings and did what they were told.
Even knowing how mindlessly callous some people can be, I still find this level of submission incredible. Are so many people capable of ignoring heart-wrenching, insistent cries of pain and misery? It seems they are.
I'm totally sure I would be one of the refuseniks. Apart from my ingrained rebelliousness and suspicion of experts and authority figures, there's no way I could willingly inflict pain on an innocent person for no good reason. And a so-called scientific experiment with no clear purpose is not a good reason. I would be out of the door like a shot.
We like to pride ourselves on being questioning and independent, looking carefully at a situation and doing the right thing. But it seems that in practice this can prove to be a fragile self-delusion.
Our cherished principles can all too easily be undermined by our human weakness for less moral considerations - wanting to please, not wanting to be awkward, or just following procedures. We're not always as strong-minded as we like to think.
