Do African Americans, Hispanics, and non-Hispanic whites differ in their explanations of the socioeconomic divide separating blacks and whites in the United States? Have such explanations changed over time? To answer these questions, I use data from the 1977 to 2004 General Social Surveys (GSS) to map race/ethnic differences in support for trends in, and the determinants of seven "modes of explanation "for blacks' disadvantage. Trends over time indicate the continuation of a long-standing decline in non-Hispanic whites' use of an ability-based (innate inferiority) explanation. Non-Hispanic whites' beliefs in a purely motivational and a purely educational explanation are increasing, however along with the view that none of the explanations offered in the GSS explain blacks' disadvantage. African Americans and Hispanics also evidence increases in a purely motivational explanation, but they differ from non-Hispanic whites in demonstrating clear declines in structural beliefs-especially the perception that discrimination explains blacks' lower socioeconomic status. These conservative shifts in blacks' and Hispanics' beliefs result in greater similarity with non-Hispanic whites over time. Notably, however significant "static" race/ethnic group differences remain: non-Hispanic whites score highest, and blacks lowest, on a purely motivational explanation, while African Americans are more likely than both non-Hispanic whites and Hispanics to endorse a discrimination-based explanation. I conclude by discussing the implications of these findings for racial policy support.
