Small sample size (92 participants), not replicated, and full of potential confounds (maybe the research assistant was extra enthusiastic when handing out envelopes, or maybe the person soliciting noticed who had what and also varied their reaction). That there was an effect at all was dubious, and privileging this hypothesis seems unwarranted. It’s plausible, but this study is very, very weak evidence.
