HT: Arnold Kling

Complex control of a complex system is a recipe for confusion at best, catastrophe at worst. Complex control adds, not subtracts, from the Knightian uncertainty problem. The US constitution is four pages long. The recently-tabled Dodd Bill on US financial sector reform is 1,336 pages long. Which do you imagine will have the more lasting impact on behaviour.

Both Kling's comment and the paper are well worth a read -
