Natives with a need for cognitive closure can approve of immigrants' economic effect when they trust pro-immigrant epistemic authorities.

Previous research on the need for cognitive closure (NFC), or the desire for epistemic certainty, has consistently found that it is associated with negative attitudes toward immigrants, among other outgroups, potentially because they represent agents of change and/or due to a general preference for perceived stability and certainty associated with right-wing politics. However, as individuals with this need theoretically prefer stable and certain knowledge, independent of the specific content, it is also possible that these individuals could have positive attitudes toward immigrants when they are provided with a positive source of information to which they can metaphorically "close" upon. In two studies (n = 397), controlling for participants' political orientation, we found that individuals with an NFC were more likely to accept immigrants when their positive effect was endorsed by an epistemic authority (Study 1), but only when they trusted this source (Study 2).
