What percentage of participants in Asch's study conformed at least once during the critical trials?

In Asch's famous study on conformity, results indicated that a significant portion of participants changed their answers to align with the group's incorrect consensus at least once during the critical trials. Specifically, 75% of participants conformed at least once throughout the course of the study. This figure is telling because it highlights the influence of group pressure on individual judgment, demonstrating that social dynamics can lead individuals to conform even when they are certain of their answers. This finding is critical in understanding the mechanisms of conformity and social influence in psychology.

Other options, while reflecting different aspects of the study's outcomes, do not accurately convey the level of conformity observed. For instance, although some participants did not conform at all, making the option of 100% incorrect, the essence of Asch's research lies in showcasing the power of social influence, which is encapsulated well by the 75% figure.
