Group size - Asch conducted variations of his conformity experiment with different numbers of confederates as the majority.
Group size- He found that when there were only 2 confederates, conformity dropped from 37% to 14%, this suggests that small majorities are easier to resist than large ones. However, influence does not continue to increase if the number of members in the majority is increased
Social support - In another variation, Asch asked one confederate to give the correct answer rather than the rest who had given the incorrect answer
Social support- The participant having an ally broke the unanimity of the group, which in turn made conformity rates drop from 37% to 5.5%.
Task difficulty 1 - When the task is made more difficult by making the lines more similar in length, the levels of conformity increase.
Task difficulty 2- This is because people are more likely to conform if they are less confident that they are correct - due to the task being more ambiguous
