In the original experiment, confederates all gave the same incorrect answer.
1 confederate was instructed to give the correct answer throughout - When participants were given the support of either another participant or a confederate (who had been instructed to give the correct answers), conformity dropped to 5.5%.
2) 1 confederate gave a different incorrect answer to the majority
When a ‘rogue' confederate gave the third answer (i.e.: not correct but not majority), conformity dropped to 9%
*The likelihood of a person conforming increases when there is unanimity in the group
