Final answer:
Having self-confidence typically leads to less susceptibility to peer pressure, not more, and enables individuals to be more relaxed in social situations. Studies like Asch's illustrate factors that help individuals resist conformity, such as the presence of allies and privacy. Peer pressure in small groups can be more effective, and conformity can often be explained by the desire to fit in with social norms.
Step-by-step explanation:
The benefit of having self-confidence is not being more likely to give in to peer pressure. Self-confidence typically helps individuals resist peer pressure, leading to more independent decision-making. When an individual has self-confidence, they tend to be more relaxed when meeting new people because they feel secure in themselves and their abilities.
Regarding informational social influence, this is more likely to occur when the answer is unclear, and when the group has expertise (d. both b and c). Collective action problems are indeed less severe in small groups because it is harder for individuals to free-ride, easier to monitor individual behavior, and peer pressure tends to be stronger (d. All of the above). In Asch's study on conformity, the ability to resist conforming was aided by the presence of an ally and the ability to keep one's answer private (d. All of the above).
Conformity, such as teenagers buying clothes to follow social norms, is frequently motivated by the desire to fit in with peers; it is not necessarily motivated by following parents' rules or saving money.
