The Dark Side of Valuing the Instrumentality of Diversity - Outgroup Devaluation as a Reaction on Non-Useful Intergroup Contact in Persons Holding Pro-Diversity Beliefs

本研究旨在填补群体间接触与多样性信念心理学研究的中心空白。虽然以往关于群体间接触的研究可以表明，不同社会群体成员之间的私人积极接触可以改善群体间关系，但它在很大程度上忽略了消极群体间接触的后果。目前的研究项目结合了对负面接触和批评对多样性商业案例的影响的研究，到目前为止，这些研究只在理论上进行。假设持有支持多样性信念的人（即出于工具原因重视多样性的人）对不同群体中无益的互动的反应是增加偏见，并降低与相关外群体进行未来接触的意愿。为了验证这一假设，在五个实验研究中系统地操纵了不同群体的合作结果。此外，还应进行具有代表性样本的纵向研究。这个项目的结果可能会提供第一个经验证据，证明以有用为中心的多样性信念的潜在负面影响。

The present research project aims at closing a central gap in the psychological research on intergroup contact and diversity beliefs. Although previous research on intergroup contact could show that private positive contact between members of different social groups improves intergroup relations, it has largely ignored the consequences of negative intergroup contact. The present research project combines research on the effects of negative contact with criticism on the business case of diversity that has until now only been approached theoretically.It is assumed that persons holding pro-diversity beliefs (i.e. persons valuing diversity for instrumental reasons) react to non-useful interactions in diverse groups with increased prejudice and decreased willingness to engage in future contact towards involved outgroups. To test this assumption, the results of cooperation in diverse groups are systematically manipulated in five experimental studies. In addition, a longitudinal study with a representative sample shall be carried out. Results of this project will potentially offer first empirical evidence for a potential negative effect of usefulness-focused beliefs in diversity.
