Lars Peter Hansen: So that’s a fascinating question. And this shows up not only in connections to economics and the climate, it also shows up in financial oversight and regulation. Early on, in discussions of financial oversight, people would say, ‘Well, this is a very complicated problem, therefore it requires a complicated solution.’ And at that step, I would say, ‘Well, wait a minute. Just because it’s a complicated problem doesn’t mean the best course of action immediately is one that’s complicated.’ Because, you know, behind complexity you can slip indiscretion, you can slip in counterproductive measures that overstate our knowledge and the like. And an advantage of a more simpler approach is transparency as well…
