Black and White Lies: Race-Based Biases in Deception Judgments

Area of Science:

• Social Psychology
• Cognitive Psychology
• Racial Bias Studies

Background:

• Deception detection accuracy is crucial in various social contexts.
• Racial biases can influence interpersonal judgments, including perceptions of honesty.
• Previous research suggests implicit biases can affect decision-making.

Purpose of the Study:

• To investigate race-based differences in deception judgments.
• To explore the role of motivation to respond without prejudice in these judgments.
• To examine the cognitive mechanisms underlying race-based deception biases.

Main Methods:

• Six studies (N=605) involving deception judgments of Black and White targets.
• Participants judged truthfulness of targets in videos discussing relationships.
• Eye-tracking technology was used in one study to monitor cognitive processes.

Main Results:

• White participants exhibited a truth bias, judging Black targets as more truthful than White targets.
• This bias was moderated by White participants' motivation to respond without prejudice.
• Black participants did not show similar race-based moderation effects.
• Eye-tracking indicated late-stage cognitive correction processes in White participants' judgments.

Conclusions:

• Systematic race-based biases exist in deception detection.
• These findings have implications for intergroup communication, lie detection accuracy, and reducing racial bias in law enforcement.
• Understanding cognitive mechanisms is key to mitigating these biases.
