Conflict and bias in heuristic judgment.

Area of Science:

• Cognitive Psychology
• Decision-Making Science
• Behavioral Economics

Background:

• Conflict is theorized to engage deliberative processing in reasoning and judgment.
• Increasing conflict may reduce reliance on heuristic responses and improve accuracy.

Purpose of the Study:

• To investigate if adding conflicting heuristic response options enhances deliberative processing and accuracy.
• To test the hypothesis that increased cognitive conflict improves judgment and reasoning outcomes.

Main Methods:

• Experimental manipulation of the number of incorrect heuristic response options in judgment tasks.
• Assessment of participant responses in argument strength and word frequency judgments.
• Comparison of accuracy and heuristic bias across different conflict conditions.

Main Results:

• Participants showed reduced heuristic bias and increased accuracy with two incorrect heuristic options compared to one.
• The presence of greater conflict reliably promoted more accurate judgments.
• Findings support the role of conflict in modulating heuristic and deliberative thought.

Conclusions:

• Cognitive conflict is a key mechanism for recruiting deliberative processing.
• Accuracy in reasoning and judgment can be enhanced by strategically increasing response set conflict.
• Simple modifications to task design can significantly improve decision-making outcomes.
