> Yet only about 200 people (0.0001%) donate kidneys to strangers per year. Why the gap between 25-50% and 0.0001%? Scott is right to point out the gap, but I don't expect him to donate another kidney next year. Even for those who follow through on their good intentions, kidney donation is a one-time event not an annual event, so it shouldn't be compared to an annual rate. Assuming that would-be kidney donors have a window about 50 years to follow through on their good intentions, the gap should be between 25-50% and 50 x 0.0001% = 0.005%.
