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.

Types and Explanations of Conformity
There are three distinct types of conformity that explain different ways people change their behaviour. Internalisation is the deepest form—you genuinely adopt both public and private views of the group, making it the most permanent. Identification is moderate—you adopt group views because you value being part of that group, but abandon them when you leave. Compliance is superficial—you publicly agree while privately maintaining your original views.
Conformity is explained primarily through two processes. Informational social influence (ISI) happens when you're uncertain and assume others know better, typically leading to internalisation. Normative social influence (NSI) occurs when you want to be accepted by the group, usually resulting in compliance. Asch's research supports both explanations—participants conformed either because they doubted their own perception or feared ridicule.
These explanations have limitations. Some psychologists argue that ISI and NSI work together rather than separately. Individual differences also matter—Asch found students were less conformist (28%) than other participants (37%). The dual-process model also fails to explain why people conform even when the group isn't present.
Try this: Think about a time you went along with friends despite privately disagreeing. Which type of conformity were you displaying, and was it driven by informational or normative influence?
Social identity theory offers another explanation for conformity. This suggests we conform to groups we identify with because they form part of our social identity. The meta-contrast principle explains why we see strong similarities between ourselves and our group members while exaggerating differences with other groups—which is why football supporters might conform to team norms even when no other supporters are present.
