Strength1- There is research to support in reducing the pressure to conform through having an ally.
Asch(1951): In Asch's unanimity of majority variation, Asch had one confederate give the correct answer throughout. Conformity dropped considerably to 5%. Showing breaking group consensus was the main influence.
This suggests that having social support helps a person to remain independent and resist conforming to the group.(Only for NSI.)
Strength 2: There is research to support for resistance to the pressure to obey through an ally.
Milgram: In one of Milgram's variations, the ppt was paired with two more confederates, pretending to be teachers with them. These confederates 'withdrew' from experiment early and it dropped from 65% to 10%.
This suggests that with support from others, confidence in increased and it reduces the likelihood of people obeying orders from an authority figure.
