Christian no more: Christian Americans are threatened by their impending minority status

Abstract Christian Americans are on track to become a minority of the U.S. population by mid-century. Research on racial demographic shifts shows majority-group members experience status threat when reminded of similar demographic changes. Public debate about religious freedom and the role of Christianity in America suggest that fast-changing religious demographics similarly elicit threat, and trigger defensive political stances, among Christian Americans. In two preregistered experiments (total N = 766 Christian Americans), reminders of religious demographic shifts evoked perceived threat to religious rights and freedoms, which in turn accounted for increases in Christian nationalism, conservative political ideology, and support for Donald Trump in the 2020 presidential election. Results illustrate how America's fast-changing religious landscape can evoke threat for Christians and how this threat may influence political reasoning.
