Maybe decision makers are too data driven? Whatever they do has to be justifiable and most people don't argue against numbers. So trying to optimize aggregated or averaged numbers looks like a sensible approach. The problem, however, is that aggregated numbers don't tell much about the gap between rich and poor and averages don't describe individuals. As a result, there is a gap between reality and what people believe the data tells us.
