This paper employs a field experiment to assess whether interpersonal contact changes domiciled individuals' attitudes of the homeless. Volunteers for Project Homeless Connect-a one-day event that provides social services to the homeless-were asked to complete a pre- and post-survey. The results provide mixed support for the contact hypothesis. After volunteering, respondents were far less likely to see homelessness as the result of individual characteristics, such as substance abuse or work aversion. However, opinion was remarkably stable when it came to policy preferences. The results cast doubt on the conventional wisdom that individuals' perceptions of the causes of homelessness track closely with their preferences for governmental policy.
