Earlier this week, he chanced upon the trailer of an up-coming film, Experimenter, that is based on the experiment.
Referred by Munger as one of the most famous social/ psychology experiments, he stated that many researchers had later referred to the result of the experiment to conclude that a voice of authority could alone be the domineering factor over an individual's decision-making process.
Their conclusions are, at one level, ironical (as they relied on or obey the authority of the Milgram Experiment in reaching their conclusions).
On another level, they are overly simplified. As the trailer touched on briefly when the Milgram character retorted that "no one was forced... the person has a choice", obedience to authority cannot be the only factor in one's thought process. Only by approaching the question with a multiple-model approach (Munger calls it the Lollapalooza Effect) can one be arriving at a decision more accurately.
