In the United States, the phrase “nation of immigrants” is used to both promote and restrict immigration. Those who use the phrase to promote immigration point to the similarities between current and previous generations of immigrants, whereas those who use it to restrict immigration emphasize the differences between the two generations. The present study examined the effects of the different versions of this historical narrative (similarity‐focused vs. difference‐focused) on 210 U.S. residents’ attitudes toward immigrants during the recent debate about immigration reform. Exposure to the similarity‐focused nation of immigrants reduced perceptions of threat from Mexican immigrants but did not affect the already low level of perceived threat from Russian immigrants. The similarity‐focused version of nation of immigrants exerted an indirect effect on perceived threat from both groups by inducing a sense of identity continuity, which reduced collective angst about the future of the people of the United States. The findings suggest that pro‐immigration policy makers clearly articulate the meaning of nation of immigrants rather than use it as a cliché as the phrase has the potential to induce inclusive attitudes.
