White and minority demographic shifts, intergroup threat, and right-wing extremism*

We present four studies (one correlational and three experimental) of American Whites that examine relationships between White and minority demographic shifts, intergroup threat, and support for extreme-right groups and actions. We focus in particular on the role of collective existential threat (i.e., a perception that the ingroup will cease to exist), along with three alternative/competing intergroup threats: status threat, symbolic threat, and prototypicality threat. Though no zero-order relationship was found between perceived White population decline and far-right variables, we find evidence that (1) perceived White population decline leads to collective existential threat net of other perceived demographic shifts, (2) collective existential threat is related to far-right support net of other threats, and (3) perceived White decline has a robust indirect relationship with measures of far-right support via collective existential threat.
