ABSTRACT

Donald Trump once claimed that he could murder someone in broad daylight and still not lose support, implying an extreme loyalty on the part of his supporters. The psychological foundation of this purported commitment is far from obvious in that many aspects of Trump’s lifestyle, personality, policies, and values are antithetical to those cherished by large segments of his base (e.g., Evangelical Christians, free-trade advocates). Political scholars, pundits, and the media have offered a number of explanations for the support for Trump that exists within his base. In this chapter, we review three of the more common media explanations, which include tribal loyalties, selective media exposure, and material self-interest, and find some support for each in the scientific literature, with support generally being weaker for the more nefarious explanations (e.g., tribal racism, bloodlust) and stronger for more banal explanations (e.g., information bubbles, perceived self-interest). We also find that many of these tendencies generalize to extreme Trump opposition, meaning that Trump support is in many ways an extrapolation of a long-standing and escalating culture war.
