The Face of Justice: How Face Perception Shapes Law and Public Policy

Human face perception plays a central role in visual and cognitive processing, guiding how people interpret, evaluate, and respond to one another in social settings. In the legal and public policy arenas, these perceptual processes influence memory, judgment, and decision-making, shaping outcomes ranging from the reliability of eyewitness testimony to the perceived legitimacy of authorities such as judges, politicians, and law enforcement. Recent studies highlight how cognitive processes such as ensemble coding, holistic and featural facial recognition, and phenomena like the cross-race effect can systematically shape crucial legal outcomes and public perceptions. Technological advances in facial recognition and machine learning have introduced new dimensions to ongoing debates about fairness, accuracy, and privacy in justice systems worldwide. Yet significant gaps remain in understanding how the perceptual, cognitive, and social mechanisms underlying face processing intersect with legal and political institutions, and how these mechanisms influence judgment and decision-making across different levels of governance.

This Research Topic aims to bring together foundational and applied research that illuminates the mechanisms by which face perception shapes justice, law, and public policy. We invite contributions that address theoretical and empirical questions such as: How do perceptual and cognitive factors in face recognition affect eyewitness identifications, courtroom decisions, and sentencing? In what ways does the facial appearance of legal professionals, public officials, and political leaders influence trust, credibility, and perceived legitimacy? By integrating perspectives from cognitive and social psychology, computational modeling, and applied legal research, our goal is to advance understanding of the theoretical mechanisms that link basic face perception processes to real-world outcomes in justice and governance.

The scope of this Research Topic focuses on cognitive, social, and computational mechanisms of face perception as they relate to law and policy. Research from developmental or lifespan perspectives is welcome when it contributes to understanding how perceptual and cognitive processes relevant to justice emerge or change across experience. To foster comprehensive exploration, we welcome articles addressing, but not limited to, the following themes:

• Cognitive and neural mechanisms underlying face processing and recognition
• The impact of face perception on eyewitness identification and its reliability
• Judicial and jury decision-making influenced by facial appearance and evaluative judgments
• The use and implications of facial recognition technology and computational models in law enforcement
• Social and psychological factors in public perception of authorities and leaders based on facial appearance
• Methods to detect and mitigate perceptual or cognitive distortions affecting legal and policy contexts
• Ethical, legal, and policy-related concerns surrounding facial data and its use in governance

By bridging fundamental cognitive science with applied legal and policy research, this collection seeks to promote dialogue between theoretical and empirical work and to deepen understanding of how face perception shapes justice at every level.
