Over at Freakonomics, Dan Ariely agrees with us that default rules can have a powerful effect on decision making. He points to a 2003 Science paper that has some nice graphs of organ donation rates in Europe for those readers who are curious about exactly how much of an effect opt-out rules have. The first graph shows organ donor rates across countries; the second one estimates the increase in donor rates from switching to an opt-out rule from an opt-in one.
