Economists have allowed themselves to walk into a trap where we say we can forecast, but no serious economist thinks we can. You don't expect dentists to be able to forecast how many teeth you'll have when you're 80. You expect them to give good advice and fix problems.
Tim HarfordI see the God complex around me all the time in my fellow economists. I see it in our business leaders. I see it in the politicians we vote for - people who, in the face of an incredibly complicated world, are nevertheless absolutely convinced that they understand the way that the world works.
Tim HarfordYou show me a successful complex system, and I will show you a system that has evolved through trial and error.
