Rosenblum, M., Schroeder, J., & Gino, F. (in press). Tell is like it is: When politically incorrect language promotes authenticity. Journal of Personality and Social Psychology.
Short Summary: This paper tests how political language influences impressions of a communicator. Using more politically incorrect (vs. correct) language made a communicator appear more authentic but less warm, and these impressions were moderated by both the political ideology of the perceiver and of the target group to whom the language was applied. (9 experiments).
