In one of Milgram's variations, the genuine participant was joined by a disobedient confederate who also played the role of teacher. The disobedient confederate refused to go on with giving shocks to the learner, Mr Wallace, and withdrew from the experiment early. This variation caused obedience levels to drop to 10% from its original 65%. This supports the idea that pressure to obey can be resisted if there is another person who is seen to disobey as it can help others to do the same, increasing the validity of social support as an explanation for resistance to social influence.
