Coyote Blog looks at the flourishing “nudge” sector of government activity and points out one of the biggest flaws:
The theory behind the idea that government should nudge (or coerce, as the case may be) us into “better” behavior is based on the idea that many people are bad at delay discounting. In other words, we tend to apply huge discount rates to pain in the future, such that we will sometimes make decisions to avoid small costs today even if that causes us to incur huge costs in the future (e.g. we refuse to walk away from the McDonalds french fries today which may cause us to die of obesity later).
There are many problems with this theory, not the least of which is that many decisions that may appear to be based on bad delay discounting are actually based on logical and rational premises that outsiders are unaware of.
But the most obvious problem is that people in government, who will supposedly save us from this poor decision-making, are human beings as well and should therefore have the exact same cognitive weaknesses. No one has ever managed to suggest a plausible theory as to how our methods of choosing politicians or staffing government jobs somehow selects for people who have better decision-making abilities.
