Increasingly, scientific consensus is failing to influence public policy. Facts, statistics and data appear insufficient to change highly politicized minds... and science has started scrutinizing why.
Alas now, this topic inevitably devolves down to our screwy American politics. And while (as I avow repeatedly) every political wing has its anti-science flakes, growing mountains of evidence suggest that one wing has gone especially frenzied in an anti-scientific snit. Or else (as that wing contends) science itself has become corrupted, top to bottom, rendering "evidence" suspect or moot. Let's examine both possibilities.
Chris Mooney, author of Unscientific America: How Scientific Illiteracy Threatens our Future, has a new book, The Republican Brain: The Science of Why They Don't Believe in Science, in which he describes how firmly some of our neighbors - even moderately well-educated ones - now cling to aphorisms, assertions and just-so stories in order to clutch a politically motivated view - or mis-view - of scientific data. Misinformation persists – and propagates – about the dangers of vaccinations, the hazards of nuclear energy, the credibility of creation vs. evolution, and the preponderance of data supporting global warming. In case after politically-redolent case, we find that evidence has a limited power to persuade on hot button issues where deep emotions are involved.
