Normative and informational confidence matching

Area of Science:

• Cognitive psychology
• Social neuroscience
• Metacognition

Background:

• Individuals' confidence judgments align with others over time in social tasks.
• The underlying mechanisms of this 'confidence matching' phenomenon require further investigation.

Purpose of the Study:

• To differentiate between informational and normative drivers of confidence matching.
• To investigate how social context influences private confidence recalibration versus public expression adaptation.

Main Methods:

• Two experiments were designed to isolate informational and normative influences on confidence.
• Participants' private confidence (via information-seeking behavior) and public confidence (reports) were measured.

Main Results:

• Both informational and normative factors were found to drive confidence matching.
• Informational factors led to genuine recalibration of private confidence, evident in information-seeking behavior.
• Normative factors influenced public confidence reports without altering private confidence assessments when feedback and joint decisions were involved.

Conclusions:

• Confidence is flexible and context-dependent, influenced by both genuine belief updates and social signaling.
• Understanding metacognitive processes requires consideration of social dynamics and adaptive confidence expression.
