Homelessness in Virtual Reality: Experiencing Social Exclusion Improves Attitudes and Behaviors Toward Unhoused People.

Virtual reality (VR) interventions are receiving increasing attention from research seeking to promote harmonious intergroup relations. Despite this, the effectiveness of VR methods and the underlying mechanisms for enhancing intergroup relations yield mixed findings. The current research examined if a 360° immersive video where participants embodied an unhoused person could improve attitudes and behavioral intentions toward unhoused people by making participants experience social exclusion and its psychological repercussions. The study (N = 210) adopted a 2 × 2 between-subject design where participants were assigned to embody an unhoused or housed person either watching the video in VR (in 3D using head-mounted devices) or in 2D (on a monitor). The study included a followup after 9 days. Results revealed that embodying the unhoused person (vs. housed control) led to increased experiences of social exclusion, need-threat, and negative emotions. These experiences, in turn, were associated with reduced negative attitudes toward unhoused individuals and heightened intentions to engage in charitable behaviors. Notably, the effects on attitudes and behavioral intentions persisted at the followup, with a stronger impact observed for participants who embodied the unhoused person in 3D compared to 2D. The findings suggest that tailoring VR video interventions to elicit social exclusion by embodying the perspective of marginalized social groups can enhance intergroup attitudes and intentions over time. Overall, this research underscores the prominence of VR-based interventions in improving intergroup harmony compared to less-immersive paradigms.
