i think the Stanford prison experiment violated ethical concerns
because, like what other have said, the prison guards didn't actually
be themselves, they pretended to be the prison guards. they behaved
in a way that would give the psychologists data that they wanted to
see. i bet none of the people playing the role of the prison guards
would of acted in that way, within the first few days if they were
actually being themselves. i think the psychologists should have
stopped the guards before it got too out of control.
