aim- to see if a consistent minority could influence a majority to give an incorrect answer in a colour perception task.
Procedure- Female participants were shown 36 blue slides of different intensity and asked to report if they were green or blue. There were 2 confederates (minority) and 4 participants (majority).
in the first part of experiment the confederates answered green for all 36 slides, in the second part they answered green 24 times and blue 12 times. There was also a control group with participants only.
Findings- when the confederates were consistent, 8% of participants said the slides were green. When they were inconsistent, 1% said they were green.
Evaluation- biased sample of 172 females from the US. Unable to generalise findings to other populations.
criticised for deceiving the participants as they were told they were taking part in a colour perception test so didn’t fully gain consent, which is seen as unethical.
