Strength of resistance for obedience?

Research support that social support can reduce pressure to obey when there is a larger group of dissenter. Gamson asked ppts to produce evidence to help an oil company run a smear campagin. 22 out of 33 reblled against these orders, which is a higher level of obedience than Milgram. Possible reason when ppts were in groups they were able to discuss waht they wanted to do, thus garnering allies in favour of their dissenting stance.
