Brendan Nyhan, assistant professor of government at Dartmouth College, found that when voters are misinformed, factual information only makes them become more rigid in their point of view! Nyhan found these instances of facts making people more rigid:
-People who thought weapons of mass destruction were found in Iraq believed that misinformation even more strongly when they were shown a news story correcting that belief.
-People who thought George W. Bush banned all stem cell research kept thinking he did that even after they were shown an article saying that only some federally funded stem cell work was stopped.
-People who said the economy was the most important issue to them, and who disapproved of Barack Obama’s economic record, were shown a graph of nonfarm employment over the prior year. It included a rising line that indicated about one million jobs were added. They were asked whether the number of people with jobs had gone up, down, or stayed about the same. Many, looking straight at the graph, said down.
