Final answer:
Internalization is a profound form of conformity because it involves changing internal beliefs to align with a group's norms, leading individuals to agree with untruths and resulting in ethically questionable actions due to group pressure and obedience to authority.
Step-by-step explanation:
Internalization is considered the most profound way of conformity because it involves changing one's internal beliefs and values, not just outward behaviors, to align with a group's norms. Solomon Asch's experiments showed that people conformed for two main reasons: to be liked by the group and because they believed the group was better informed.
This level of conformity indicates a deep-seated need for acceptance and accuracy, potentially leading individuals to agree with an untruth with little persuasion. Conformity can lead to ethically and morally questionable acts due to the pressure of group norms, as well as obedience to authority figures, as demonstrated by Stanley Milgram's experiment. The drive to conform varies depending on whether responses are public or private; with public responses tending to result in higher levels of conformity to avoid social disapproval.
