What is wrong and right in economics?

Dani Rodrik

"Either you come up with a new technique or piece of evidence to shore up conventional wisdom. Or you challenge the conventional wisdom. The latter is a high risk, high return strategy. It is high risk for all the reasons I have mentioned previously. But it is high return because anything that has turned into conventional wisdom is almost by definition wrong, or at least, overstated. So done right, challenging conventional wisdom is a successful research strategy that is bound to pay off.

 In my own case, every piece of conventional wisdom I challenged had already become a caricature of what sounds economics teaches us."
