“…It has been demonstrated that the more prosocially oriented people are, the more time they spend on others' requests (McClintock & Allison, 1989), the more they donate money for charity (Van Lange et al, 2007), the more socially mindful they select preferable objects (Van Doesum, Van Lange, & Van Lange, 2013), the more often they interpret situations as a cooperative endeavor (Yamagishi et al, 2013), and the more they value moral behavior, including fairness, honesty and equality (Liebrand, Jansen, Rijken, & Suhre, 1986;Sattler & Kerr, 1991;Joireman et al, 2003). Prosocials and proselfs differ in their world views resulting in different expectations of others' behavior (see also generalized expectations in Pletzer et al, 2018;Bogaert, Boone & Declerck, 2008;Van Lange, 1992;Kelley & Stahelsky, 1970): Proselfs think that others would act in a selfish way when given the option to cooperate, whereas prosocials have a stronger initial expectation that others will cooperate in such situations.…”
