[quote name='camoor']The scientific truth is often complex and counter-intuitive. All too often, politics are about selling a simple story to simple people.[/QUOTE]
Right. Which is precisely why the GOP still likes to peddle the "cut your taxes means all good things will happen for everyone" fairy tale, even though people paying attention to all major economic indicators the last 11 years (or also the last 31) recognize that it's as close to reality as Rapunzel.
Similarly, we all know that the political narrative of "kill the teacher's unions!" is more effective than its dual counterparts:
1) regulate the

out of Wall Street (w/r/t state and federal revenues)
2) stop being shitty parents (w/r/t the poor quality of education)
But it's more effective to be romantic and charismatic, no matter how far from the truth, than close to the truth and pointing to the flaws of the American people.
Think of how it applies to us and our lives. Anytime a study is released that shows that video games have some risk factor associated (say, obesity) we demonize the hell out of the author, dismiss the results of the study, or acknowledge the results of the study but don't think it applies to us at all. We don't want to believe that our actions and interests contribute to negative consequences in the world.
Look at the divide in claims for austerity: both parties are pandering to their bases and calling it "class warfare." Republicans are brazen in making austerity only apply to all but the top; the Paul Ryan plan begins the dismantling of social programs we've relied on and that most people love; GOP-led states want to annihilate unions and so on, and they all want to lower the income tax rate for the wealthy, reduce or eliminate the capital gains tax, and bring the corporate tax rate to its lowest level since the Great Depression. Deprivation for some, a smorgasbord of benefits for another. Democrats, meanwhile, cite Pew Research data that show the majority of Americans want to see the current tax cuts (the Bush Tax Cuts, renewed by Obama in November) expire for the top 2% of income earners. But it's mathematically neceessary that the bulk of those wanting to see those tax hikes are not those in the 2% of the wealthiest.
The story is clear: austerity for thee, not for me. Republicans and Democrats will continue this insane, inconsistent joust through 2012 and the rest of our lives. You know, in the meantime, who won't be getting elected AT ALL? The person who stands no chance in hell of getting a plurality of the votes?
The sensible candidate who says "

IT, ALL Y'ALL TAXES SHOULD BE GOING UP! AND LET'S CUT SOME SHIT, TOO, STARTING WITH THE MILITARY AND CORRECTIONS SYSTEMS."
S/he won't be getting many votes at all. Look, we may love Warren "Take my taxes, please!" Buffett right now, but he's anomalous in terms of both his wealth and his willingness to provide more himself. Most people want to solve the problem without disrupting or putting at risk their own standard of living. Therefore, we prefer to be baffled with bullshit instead of dazzled by brilliance.
