Final answer:
Participants in Asch's conformity experiment were most likely to conform in the presence of a group with at least three people and a unanimous group consensus. Conformity was influenced by the desire to fit in or the belief that the group was better informed, but could be resisted with the presence of an ally or private responses.
Step-by-step explanation:
In Solomon Asch's conformity experiment, participants were most likely to conform when they were in a situation where B. they are in a group with at least three people and C. they are in a group in which everyone else agrees. According to Asch, the pressure to conform arises because individuals want to fit in with the group or believe the group is better informed. Asch's experiments showed that well-educated people would often agree with an obviously erroneous group consensus, suggesting a strong influence of group pressure on individual judgment. Factors such as group size, unanimity of the group, and the public or private nature of responses affected the likelihood of conformity. Additionally, Asch discovered that resistance to conformity was facilitated by b. the presence of an ally and c. the ability to keep one's answer private.
