Social Exclusion and Psychological Outcomes

Social exclusion denotes the experience of being ignored, rejected or ostracised by one’s social group and poses a fundamental threat to human well-being. Drawing on evolutionary and sociocognitive frameworks, exclusion undermines basic needs for belonging, self-esteem, control and meaningful existence. Neuroimaging and electrophysiological studies point to engagement of brain regions implicated in physical pain and threat detection, notably the dorsal anterior cingulate cortex and insula, alongside heightened event-related potentials when exclusionary cues are processed. Psychologically, exclusion triggers negative affect, elevated stress responses and, over time, can foster anxiety, depression, aggression or maladaptive coping such as withdrawal or radicalisation. Individual differences in rejection sensitivity, cultural norms and pre-existing mental health conditions moderate these effects. Interpersonal and intrapersonal processes interact in a cyclical fashion: exclusion may precipitate emotional dysregulation and social withdrawal, which in turn increases the risk of further ostracism. Recent translational research has explored interventions ranging from mindfulness-based resilience training to digitally mediated inclusion cues, underscoring the global importance of understanding and mitigating the adverse outcomes of social exclusion across educational, occupational and online contexts.

Social Exclusion and Psychological Outcomes publication trend

The graph below shows the total number of articles in social exclusion and psychological outcomes across all publications each year (not limited to Nature Index journals).

Technical terms

Ostracism: The act of ignoring or excluding an individual from a social interaction or group, often experimentally induced via virtual paradigms.

Fundamental social needs: Core psychological requirements—belonging, self-esteem, control and meaningful existence—threatened by exclusion.

Event-related potential (ERP): Time-locked brain responses measured via EEG that reflect the neural processing of stimuli, including P2 and P3 components linked to social reward and expectancy.

Temporal need-threat model: A theoretical framework describing stages of exclusion—immediate reflexive reaction, reflective coping and resignation outcomes.

Rejection sensitivity: Individual predisposition to anxiously expect, perceive and overreact to potential exclusionary cues.
