The News Interest Index supplied 369 unaffiliated White respondents for the experiment
Evidence
Data were obtained from the News Interest Index (N = 1,202; Pew Research Center for the People & the Press, 2001). Our focal analyses were limited to White respondents who identified themselves as unaffiliated with either of the two major U.S. political parties (n = 369; 183 men, 186 women; mean age = 45.12 years, SD = 17.35). Respondents were randomly assigned to one of two survey forms that asked slightly different questions, providing an experimental manipulation of racial-shift salience. One survey form asked participants if they had heard that California had become a majority-minority state (racialshift condition); the other asked participants if they had heard that Hispanics had become roughly equal in number to Blacks nationally (control condition). Finally, respondents were asked which party they leaned more toward (1 = Republican, 0 = Democrat), indicated their general political ideology (1 = very liberal, 5 = very conservative), and reported their demographic information (e.g., gender, age). — Maureen A.
