Cross-Cultural Examination of the False Consensus Effect

Area of Science:

• Social Psychology
• Cross-Cultural Psychology
• Cognitive Bias

Background:

• The false consensus effect (FCE) is the tendency to overestimate the extent to which others share one's beliefs and behaviors.
• Understanding cultural variations in cognitive biases like FCE is crucial for cross-cultural psychology.
• Previous research has not extensively compared FCE magnitude across distinct cultural groups like Koreans and European Americans.

Purpose of the Study:

• To investigate and compare the magnitude of the false consensus effect (FCE) between Koreans and European Americans.
• To examine how cultural differences influence FCE across different categories of personal and behavioral choices.
• To explore the cultural implications of observed differences in the FCE.

Main Methods:

• Two studies employed a traditional false consensus paradigm.
• Study 1 assessed FCE across three categories of personal choices.
• Study 2 investigated FCE in behavioral choices within hypothetical conflict scenarios.

Main Results:

• The false consensus effect was evident in both Korean and European American samples.
• The FCE tended to be significantly stronger among Koreans compared to European Americans.
• Cultural differences in FCE magnitude were dependent on the specific domain of choices, as shown in Study 1.

Conclusions:

• The false consensus effect is a cross-culturally present phenomenon but its strength varies.
• Koreans demonstrate a more pronounced FCE than European Americans, particularly in certain choice domains.
• Findings highlight the importance of considering cultural context when examining social cognitive biases.
