Previous psychological studies have found that conservatives tend to be more structured and persistent in their judgments whereas liberals are more open to new experiences. The latest study found those traits are not confined to political situations but also influence everyday decisions.

This phenomenon may help explain why large numbers of Americans incorrectly think that Saddam Hussein was directly involved in planning the Sept 11, 2001, terrorist attacks, and that most of the Sept. 11 hijackers were Iraqi. While these beliefs likely arose because Bush administration officials have repeatedly tried to connect Iraq with Sept. 11, the experiments suggest that intelligence reports and other efforts to debunk this account may in fact help keep it alive.
