Ja. Krosnick et La. Brannon, THE MEDIA AND THE FOUNDATIONS OF PRESIDENTIAL SUPPORT - BUSH,GEORGE AND THE PERSIAN-GULF CONFLICT, Journal of social issues, 49(4), 1993, pp. 167-182
When the United States began its overt military conflict with Iraq in
January 1991, the American news media focused attention powerfully and
seemingly unceasingly on the Gulf crisis for a period of almost three
months. Through analysis of data collected in a panel survey conducte
d before and after the war, we found that paralleling this surge in me
dia coverage were significant alterations in the ingredients of Americ
ans' assessments of George Bush's job performance. After the war, thes
e assessments were based much more on citizens' beliefs about his effe
ctiveness in managing the conflict, and much less on their confidence
in his handling of other foreign relations matters or the domestic eco
nomy. We found as well that these shifts were regulated by citizens' l
evels of political knowledge, exposure to political news, and interest
in the war. Greater shifts were associated with higher levels of know
ledge and lower levels of exposure and interest. These findings challe
nge traditional views of these dimensions of political involvement and
support an alternative view derived from contemporary psychological t
heories of information processing.
