People experiencing homelessness (PEH) are stigmatized. Their dehumanization contributes to their social exclusion. While previous research underscores the role of intergroup contact in reducing homelessness stigma, this paper is concerned with the precursor step of fostering contact intentions. Therefore, we tested the effectiveness of a psychosocial strategy based on the induced-hypocrisy paradigm for promoting contact intentions with PEH through humanness attribution enhancement. Induced hypocrisy is an effective way to encourage prosocial behaviors. In this two-step procedure, people are asked to promote a social norm (i.e., the normative salience step) and then recall their own past failures to comply with it (i.e., the transgressive salience step). In this preregistered study (N = 207), we randomly assigned participants into three conditions, namely, control, norm-alone, and induced-hypocrisy. We then measured participants’ humanness attributions to PEH and their contact intentions with them. The findings revealed that the induced-hypocrisy condition surpassed the two control conditions in fostering higher contact intentions, indicating the need for interventions fostering social connection by priming both values and past behaviors. In addition, exploratory results showed that the induced-hypocrisy strategy reinforces some humanness attributions toward PEH, leading to greater contact intentions. Discussion focuses on the role of humanness attributions in preventing PEH stigma with the induced-hypocrisy strategy and highlights the implications of the results for both the prevention of PEH stigmatization and for the induced-hypocrisy paradigm.
