The aim of this experiment is to see if people will conform to social influences and give incorrect answers in cases where the correct answers are always obvious.
In the experiment there are 3 confederates and 1 participant. the confederates are all under instruction to give the incorrect answer to an easy question where the answer is obvious.
The professor will ask which of the three lines to the right of the dotted line matches the line on the left side of the dotted line. The three confederates will all give the same wrong answer.
the researchers and people doing the experiment will watch to see if the participant agrees with the three confederates on the obvious wrong answer or if he will stray from the group and answer the obvious correct answer
the researchers found that even with this easy question, people were likely to conform to the group to avoid disapproval. they found that participants conformed to 36.8% of critical trials, 74% of participants conformed at least once and 26% never conformed.
some participants revealed that they felt doubt about the accuracy of their judgement for this reason. post experiment interviews reveal that they conformed due to compliance, they changed their public behaviour but not their private thought (disagreed privately) to avoid disapproval
