How Studies of Obedience Have Been Shown to Lack Validity

To a certain extent studies of obedience have been shown to lack experimental validity, ecological validity and mundane realism.

Experimental validity is: the validity of the experiment I the context in which it was carried out. If a study lacks experimental validity, the participants do not believe in the set-up. Ecological Validity is whether or not the research is valid outside of the experimental situations- real life. Mundane realism is: the use of an artificial situation that resembles a natural situation e.g. a lab experiment set up as a classroom.

Milgram's study of obedience is a classic example of a study that lacked in experimental validity and also in mundane realism. Milgram's study consisted of a confederate having to answer questions, which if they got wrong they would fake being given an electric shock by the machine they were attached to. The participant's role was to give these electric shocks to the confederate every time a question was answered wrong, and also the voltage would be turned up with every answer wrong. Along with this Milgram took part as a confederate who would encourage the participant to give the shocks by saying things such as, "This has to be done."

Milgram aimed to discover how many of the participants would give electric shocks of such high voltage that they would have killed the confederate had they actually been receiving them.

Milgram's study lacked experimental realism because the participants could not have believed in the setup. Orme and Holland said that surely Milgram should have been the confederate receiving the shocks, since this would have made it far easier to believe in the setup. However Rosenhan said that 70% of the participants did believe in the whole setup, but there is 30% who did not. Orme and Holland also said that, obedience is a demand characteristic since the participants are required to obey experimental orders. Therefore it made it difficult for the participants to believe in the setup of the experiment.

Milgram's study however did not entirely lack in validity since it had good ecological validity. This is because Milgram created several variations for the experiment. For example he created situations where the victim (confederate) could not be seen or heard, or when the victim could be heard, or also when the victim could be both seen and heard. These variations were also carried out in a run-down office instead of a laboratory, therefore changing the results they got dramatically.
