I'm looking forward to when the behavioral science people actually implement all their policies based on individuals "biases" that make them make "bad" decisions and discovering that all the biases update when someone tries to take systematic advantage of them1, just like we discovered about unemployment and inflation in the 70s.
1: Note: You probably can take systematic advantage of biases if the cost of analyzing those biases is low. Marketing that places the more expensive item prominently is an obvious example. So long as the difference in price is still fairly low, people will often choose convenience rather than making cost comparisons. Of course, then your are left wondering if it is a bias towards prominent products or towards convenience of shopping and convenience of not needing to spend energy on price comparisons.
For an example where it doesn't work as well because of price differences, see how well "product location" makes a difference at car dealerships.
