Counterpoint However, Charles Sheridan and Richard King (1972) conducted a study
using a procedure like Milgram's. Participants (all students) gave real shocks to a puppy
in response to orders from an experimenter. Despite the real distress of the animal,
54% of the men and 100% of the women gave what they thought was a fatal shock.
This suggests that the effects in Milgram's study were genuine because people behaved
obediently even when the shocks were real.
Alternative interpretations of finding:
Another limitation is that Milgram's conclusions about blind obedience may not be
justified. Alex Haslam et al. (2014) showed that Milgram's participants obeyed when
the Experimenter delivered the first three verbal prods (see facing page). However,
every participant who was given the fourth prod ('You have no other choice, you must
go on') without exception disobeyed. According to social identity theory (SIT),
participants in Milgram's study only obeyed when they identified with the scientific
aims of the research (The experiment requires that you continue).
When they were ordered to blindly obey an authority figure, they refused.
This shows that SIT may provide a more valid interpretation of Milgram's findings,
especially as Milgram himself suggested that 'identifying with the science' is a reason
for obedience.
