Consistency - Moscovici et al
conducted a lab experiment with female pps, put into 1 of 2 groups their task was to decide whether slides shown were green or blue. In 1 group the confederates were consistent with giving the incorrect answer - 8% agreed with the confederates. In the other groups were inconsistent - 1% agreed.
AO3 - lab study, low ecological validity, beta bias as only women were used, high control but the task was artificial & lacks mundane realism.
