Loneliness is often viewed as an individual issue stemming from personal shortcomings, but this narrative is incomplete and harmful. It overlooks the role of social and structural factors that contribute to unequal distribution of loneliness, framing it as a social justice issue. The dominant narrative emphasizes individual deficits, leading to interventions that focus on personal change rather than addressing systemic causes. This approach fails to recognize that loneliness is influenced by social inequalities, marginalization, and structural stigma, which are often overlooked in psychological research. The narrative also contributes to stigmatizing loneliness, reinforcing social exclusion and making individuals feel isolated. Research shows that loneliness is more prevalent among marginalized groups, including migrants, racial and ethnic minorities, LGBTQ+ individuals, people with disabilities, and those with low socioeconomic status. Social exclusion, discrimination, and cultural hegemony play significant roles in perpetuating loneliness. Addressing loneliness requires a shift in perspective, emphasizing structural change and social justice rather than individual solutions. Policies and practices that promote inclusion, reduce discrimination, and support marginalized groups are essential to tackling the root causes of loneliness. Recognizing loneliness as a social justice issue is crucial for developing effective, sustainable interventions that address the broader societal impacts of isolation.Loneliness is often viewed as an individual issue stemming from personal shortcomings, but this narrative is incomplete and harmful.
