Individual consistency and flexibility in human social information use

Area of Science:

• Cognitive Psychology
• Evolutionary Anthropology
• Behavioral Economics

Background:

• Social information (information from others) is crucial for adaptive learning.
• Individual differences in social information use exist, potentially limiting flexibility.
• Theoretical models of cultural transmission assume flexible social learning strategies.

Purpose of the Study:

• To investigate if individuals flexibly adjust social information use based on current conditions.
• To determine if social information valuation is consistent across different decision-making contexts.
• To explore the relationship between individual differences in social information use and personality traits.

Main Methods:

• Participants played two distinct computer games requiring decision-making.
• Social information use was measured in relation to personal information gathering.
• Personality questionnaires, including collectivism scales, were administered.

Main Results:

• Individuals demonstrated flexibility, employing a 'copy-when-uncertain' social learning strategy.
• Decision investment was adjusted based on the combined reliability of personal and social information.
• Consistent individual differences in social information use were observed, correlating with collectivism.

Conclusions:

• Human social information use is strategically flexible, adapting to uncertainty.
• Stable individual differences in social learning tendencies coexist with strategic flexibility.
• Cultural transmission models are supported by the observed 'copy-when-uncertain' strategy.
