Note: Entries are unstandardized coefficients, standard errors, and standardized coefficients from least squares regression based on unweighted data. Dependent variable in first equation is overall opinion toward Blacks. Responses range from 1 (“very unfavorable”) to 4 (“very favorable”). Dependent variable in second equation is views concerning the main reason “many black people can’t get ahead these days” — a forced choice between “racial discrimination” or blacks themselves are “mostly responsible for their own condition”. Responses range from 1 (believe “very strongly” that blacks themselves are responsible) to 4 (believe “very strongly” that racial discrimination is to blame). Full question wording is in Appendix 2.
