How does the number of people in a group impact social influence?

The impact of the number of people in a group on social influence is nuanced, as it can indeed either increase or decrease conformity depending on various situational factors. When the size of the group increases, typically, conformity tends to increase because individuals may feel more pressure to align their behaviors and opinions with those of a larger group. This phenomenon is often tied to social norms and the desire to be accepted.

However, there are instances when a larger group might also lead to decreased conformity. For example, if the size of the group becomes too large, individuals may feel a sense of anonymity or a diffusion of responsibility, making them less likely to conform to the group's influence. Additionally, if a party within the group holds a contrary opinion, this can empower others to also express dissent, leading to a decrease in overall conformity.

Thus, the relationship between group size and conformity is not straightforward and can vary based on the specific context and dynamics of the group, justifying why the correct answer reflects that it can both increase or decrease conformity.
