We awarded funding to Dr. Roos Vonk (Radboud University) and Dr. Thijs Verwijmeren (Radboud University) for this study. Moral refusers, such as vegetarians, are often derogated and their messages meet resistance, due to self-defence and self-justification. The purpose of this research is to find ways to overcome this defence, so that meat eaters become more open-minded towards persuasive messages.
