P -Strength – similar findings have been found in recent years.
E - Burger (2009) – Found levels of obedience almost identical to those found by Milgram some 46 years earlier. Additionally, other researchers have found no correlation between each study’s year of publication and amount of obedience found in it.
E -This matters because similar results have been found regardless of the period in time. This means that these high levels of obedience did not just occur due to a specific situation or event.
L -This suggests that Milgram’s study is high in temporal validity
