The significance of the Milgram obedience experiments resides inevitab
ly in the constructions of these studies-in the meaning and interpreta
tions that this research holds for students and researchers. This pape
r reviews these constructions, with an emphasis upon the domains of re
levance that have been associated with the obedience experiments. Cons
idered first are issues bearing on the internal validity of the obedie
nce paradigm. A brief historical excursion then examines Hannah Arendt
's thesis of the ''banality of evil,'' a thesis with a powerful and co
ntroversial legacy of its own. To understand what those who are encoun
tering the Milgram experiments for the first time are learning, I cons
ider next the manner in which the ecological validity of the obedience
research is discussed in contemporary texts. The paper concludes with
a review of recent conceptual analyses of evil from the perspective o
f the obedience experiments.
