Maybe there was an edit but it's the opposite, 66% disobeyed.
So of the entire populace of Milligram participants, 16.5% believed and obeyed.
That's a much, much smaller claim than the popular belief of what Milligram presented.
However, it's still possible that you only need ~16.5% to believe & obey authority for things like the Nazi death camps to occur.
Even if we take the 16% though, that's one in six people willing to deliver very obvious direct harm and/or kill another human from exceptionally mild coercion with zero personal benefit attached other than the benefit of not having to say "no". That is a lot.
