A limitation of Asch’s study is that it lacks mundane realism, meaning it doesn't reflect real-life situations where people conform. In the study, participants were asked to complete a simple task of identifying which line matched the length of another, which is not something people typically encounter in everyday life. The artificial nature of this task makes it unlikely that the results accurately represent how people conform in more natural settings. In real-life situations, people often conform for social or emotional reasons, not just because of an obvious, simple task like in Asch’s study. This lack of realism means that the findings may not be applicable to real-world scenarios, reducing the ecological validity of the study. Therefore, while the study shows how people might conform in a lab setting, it doesn't necessarily tell us much about conformity in everyday life.
