His life's mission as a psychologist has not been merely to discover imperfect correlations; he has sought to actively transform the lives of the powerless.
Many were due to things that are open to non-behavioural economics, "like better risk analysis, how we identify hidden correlations".
Once these correlations are good enough, the machine will be able, reliably, to tell faces from not-faces in its training set.
There's plenty such evidence, and, before half the people who read this blog go ballistic, it really shouldn't be considered offensive to point out the correlations between character types and political affiliation.
This in turn has long-lasting effects on the economy.Uncertain, with a chance of sub-optimal equilibriumAlmost all these correlations derive from weather data from the past five or ten years.
As experience shows, correlations can change suddenly.Financial economists also need better theories of why liquid markets suddenly become illiquid and of how to manage the risk of "moral hazard"—the danger that the existence of government regulation and safety nets encourages market participants to take bigger risks than they might otherwise have done.
These models mistakenly assume that the volatility of asset prices and the correlations between prices are constant, says Mr Scholes.
Such spurious correlations are often recorded in journals eager for startling papers.
Using the same assumptions as for their equity home-bias calculations, the authors find correlations in consumption growth very similar to those actually observed among the G7 countries.All four puzzles are, in fact, interlinked.
Giving the NSA a vast database of phone calls, and inviting them to search for correlations that might be predictive of terrorist activity, is likely to generate a massive number of false positives.It's not just the government that we need to watch here; the phone companies themselves routinely store call and location data from your phone, aggregate it, and sell it to third parties.
"Curiosity about neuroscience among economists has outstripped what we have to say, for now," admits Mr Camerer.A standard MRI identifies activity in too large a section of the brain to support much more than loose correlations.
