Molding the Past: Biased Assimilation of Historical Information1

Abstract

The present study examined whether individuals' current political worldviews would bias perceptions of historical information gathered over the course of their lifetime. Kent State University students from 1995 and 2000 reported their political ideologies (e.g., conservative, liberal) and responded to items assessing their culpability and global attributions about the shooting of demonstrators by the National Guard at Kent State in 1970. The 1995 data revealed consistent support for biased responding to culpability and global attribution items. The 2000 data replicated the political ideology differences of the 1995 data. However, by including knowledge of the incident as an independent variable, the 2000 data revealed that the political ideology bias was strongest among people reporting high knowledge about the event.
