Beliefs about sources of the socioeconomic disadvantage suffered by blacks
have been investigated by major continuing surveys since the 1970s. Results
indicate that most whites tend to place responsibility mainly on blacks th
emselves, with the primary emphasis on a presumed lack of motivation on the
part of blacks. Drawing on two survey questions used by the Gallup organiz
ation, we show that at the height of the civil rights movement in 1963, whi
te respondents tended to blame whites and blacks equally for racial disadva
ntages, but that this changed sharply in the late 1960s. The change, which
may well have been a reversion to pre-1960s beliefs, was probably a result
of both the enactment of civil rights legislation, which supposedly ended r
acial discrimination, and the eruption of riots in Detroit, Newark, and oth
er cities, which differed drastically from the earlier nonviolent protests
in the South. This shift in public beliefs indicates that attributions of b
lame for socioeconomic disadvantage are not as fixed as later data suggest.
Our analysis makes strategic use of a split-sample experiment to distingui
sh substantive change over time from change resulting from variations in th
e wording of survey questions.
