Among Republicans, it has become politically correct to be politically incorrect. Actually that’s the most politically correct thing that you can possibly be. As soon as you announce that you’re politically incorrect, you’re guaranteed smiles and laughter, and probably thunderous applause. Proudly proclaiming your bravery, you’re pandering to the crowd.A math-filled new paper, by economists Chia-Hui Chen at Kyoto University and Junichiro Ishida at Osaka University, helps to explain what’s going on. With a careful analysis of incentive structures, they show that if self-interested people want to show that they are independent, their best strategy is to be politically incorrect, and to proclaim loudly that’s what they are being. The trick is that this strategy has nothing at all to do with genuine independence; it’s just a matter of salesmanship, a way to get more popular.
