Informational Social Influence Psychology Definition
What Does Informational Social Influence Mean in Psychology?
Informational social influence occurs when individuals conform because they believe others have more accurate knowledge about a situation. This type of social influence is particularly common in ambiguous situations where people seek guidance from those they perceive as experts.
Informational Social Influence Psychology Definition (AQA & Authors)
According to Deutsch and Gerard (1955), informational social influence is a psychological process where people conform due to a desire to be correct in uncertain situations. The AQA A-Level Psychology definition aligns with this, stating that it occurs when individuals accept information from others as evidence about reality.
