This study comes in a series in which Piff tries to iso­late the ways that wealth­ier peo­ple dif­fer socially.  Last year, Piff pub­lished a paper show­ing that wealthy indi­vid­u­als are more likely to exhibit a num­ber of uneth­i­cal behav­iors.   As Piff told New York Mag­a­zine last year, “While hav­ing money doesn’t nec­es­sar­ily make any­body any­thing,” Piff says, “the rich are way more likely to pri­or­i­tize their own self-interests above the inter­ests of other peo­ple.  It makes them more likely to exhibit char­ac­ter­is­tics that we would stereo­typ­i­cally asso­ciate with, say, assholes.”
