That's pretty much what this recent study found: "In a series of studies in 2005 and 2006, researchers at the University of Michigan found that when misinformed people, particularly political partisans, were exposed to corrected facts in news stories, they rarely changed their minds. In fact, they often became even more strongly set in their beliefs. Facts, they found, were not curing misinformation. Like an underpowered antibiotic, facts could actually make misinformation even stronger." (italics mine)
This is apparently why the Right continues to trumpet the everlasting salvation that they believe lay in tax cuts for all and especially for the wealthy...never mind that Reagan Fed Chief Paul Volcker, Reagan Economic Advisor David Stockman, and Alan Greenspan ALL have said how disastrous the Bush tax cuts were for the American economy. But you know how it goes - now that the financial world's two most powerful men of the last half century have come out against extending Bush's tax cuts, well, that means they're socialist communist nazis...and they might even be French! Horrors!
So that's why they ignore the past ninety years of American history and pretend that the Republicans are truly the party of economic sanity. That's why they ignore 97% of the world's climatologists and the Mount Everest of evidence pointing to the reality of global warming caused by humanity (which now includes a 40% decrease of ALL the oceans' phytoplankton since the 1950s - and the decrease is greatest in the parts of the ocean that have warmed the most). That's why they ignored the war crimes committed by Bush/Cheney even when it included torture (which even George Washington and Abraham Lincoln refused to do when our nation was in far worse straits). That's why they're sure that racism plays little or no part in the Republican and Tea parties.
What's the answer? How do we get them to listen to fact? I honestly don't know...but here's an observation: every time there's an unseasonably cold day, my neo-con friend tends to point out about how it's proof that there's no such thing as global warming, and said exchange has become a bit of a standing joke between us. You see, he doesn't care that the rest of the planet is so much warmer than normal - it's what he physically sees and feels that matters. So is this the answer? Must those on the Right physically see and feel how bad the economy's going to get under the GOP, how bad the weather's going to get if we ignore the climatologists before Joe Republican starts to think, "well, just maybe those Democrats were right about something"? Is there a point where obvious facts will finally overcome their political dogma?
