Understanding Conformity and Asch's Research
Conformity occurs when an individual's attitudes, opinions or behaviour change to match the majority group. This social influence happens because of pressure to follow group norms, regardless of whether they're right.
Solomon Asch's famous 1955 experiment revealed fascinating insights about conformity. Using a simple line-comparison task, he found that 75% of participants conformed at least once to obviously incorrect answers when surrounded by confederates (actors) giving wrong answers. Across all trials, the conformity rate averaged 37%.
Asch also investigated key variables affecting conformity. He discovered that group size influenced conformity (32% with just 3 confederates), but adding more people didn't significantly increase this effect. When he broke unanimity by having one confederate give the correct answer, conformity plummeted to just 5.5%. Increasing task difficulty by making lines more similar raised conformity rates substantially.
Did you know? When Asch's experiment was replicated decades later by Perrin and Spencer, they found much lower conformity rates, suggesting conformity levels may be influenced by the cultural and political climate of the time.
The experiment has limitations—it used only male American students in an artificial lab setting, making it gender-biased and potentially not representative of real-world conformity. Despite these criticisms, Asch's method became the accepted paradigm for studying conformity in psychology.
