Misperceptions about Iraq war contribute to support for it

A majority of Americans have held at least one of three mistaken impressions about the U.S.-led war in Iraq, according to a new study released Thursday, and those misperceptions contributed to much of the popular support for the war.

The three common mistaken impressions are that:

-U.S. forces found weapons of mass destruction in Iraq.
-There's clear evidence that Iraqi President Saddam Hussein worked closely with the Sept. 11 terrorists.
-People in foreign countries generally either backed the U.S.-led war or were evenly split between supporting and opposing it.

Overall, 60 percent of Americans held at least one of those views in polls reported between January and September by the Program on International Policy Attitudes, based at the University of Maryland in College Park, and the polling firm, Knowledge Networks based in Menlo Park, Calif.

In fact, no weapons of mass destruction have been found in Iraq. U.S. intelligence has found no clear evidence that Saddam was working closely with al-Qaida or was involved in the Sept. 11, 2001, attacks. Gallup polls found large majorities opposed to the war in most countries.

PIPA's seven polls, which included 9,611 respondents, had a margin of error from 2 to 3.5 percent.

Among those with one of the three misconceptions, 53 percent supported the war. Among those with two, 78 percent supported it. Among those with three, 86 percent backed it. By contrast, less than a quarter of those polled who had none of the misconceptions backed the war.

The analysis released Thursday also correlated the misperceptions with the primary news source of the mistaken respondents. For example, 80 percent of those who said they relied on Fox News and 71 percent of those who said they relied on CBS believed at least one of the three misperceptions.

The comparable figures were 47 percent for those who said they relied most on newspapers and magazines and 23 percent for those who said they relied on PBS or National Public Radio.
