Asch’s conformity study was a laboratory experiment, which allowed control of potential confounding variables. Therefore, it has high internal validity
The study has been criticised for low ecological validity. the task used is artificial and quite different from how we experience conformity in our daily lives
There is a lack of generalisability to a wider population as the sample consisted of only male, American students
The findings may not reflect conformity across cultures as the US is an individualistic culture. The degree of conformity would be high in collectivist cultures that have a greater emphasis on the group.
The findings of the study was not the same when replicated. Perrin and Spencer replicated the study on a sample of UK Engineering students. Across 396 trials. only one participant conformed. It suggests that engineering students felt more confident about their abilities and therefore were less conformist
Asch carried out his study in the 1950s which was an especially conformist time in America. Therefore it made sense to conform to establish social norms. However, society has changed a great deal since them and it doesn’t apply to the context now.
What were some ethical issues of Asch’s study?
The use of deception: thought they were taking part in a visual test experiment
Lack of protection from harm: participants reported experiencing a fear of rejection or anxiety related to the pressure to conform
