Stumbling and Mumbling: Choosing charlatans

Why are charlatans listened to, even when they obviously don’t know what they’re talking about? How do bogus ideas spread? Chris Dillow looks at some recent psychological studies and draws a damning conclusion:

“One implication of all this is that a public service broadcaster as the BBC purports to be cannot be impartial. If you offer people two sides of a story or two talking heads, many will choose the charlatan or false story over the true one. And we’ll get increased polarization – which might make for good TV but not necessarily for good politics or a good society.

“But I think the implication is more devastating. All this undermines the conventional liberal faith in the marketplace of ideas. John Stuart Mill thought that ‘wrong opinions and practices gradually yield to fact and argument.’ Experiments, however, confirm our real world experience that in fact the opposite can happen. And this isn’t simply because of our biased and dysfunctional media.”
