“…People are usually more familiar with incumbents (Erikson, 1971); exposure and familiarity increase liking generally (Festinger, Schachter, & Back, 1950;Zajonc, 1968) and vote-getting in particular (Grush, 1980;Grush, McKeough, & Ahlering, 1978;Schaffner & Wandersman, 1974). People are motivated to rationalize existing social arrangements ( Jost et al, 2004), of which winning candidates are an example (Beasley & Josslyn, 2001;Kay et al, 2002). And because people tend to be sensitive to losses (Tversky & Kahneman, 1991), and incumbents represent what is already established, incumbency effects may be driven by concerns associated with change, loss, and risk (Quattrone & Tversky, 1988).…”
