FT.com / Weekend columnists / Tim Harford - Given the choice, how much choice would you like?

  • lots of choice makes people less likely to choose anything, and less happy when they do choose
  • The bigger display attracted more customers but very few of them actually bought jam. The display that offered less choice made many more sales – in fact, only 3 per cent of jam tasters at the 24-flavour stand used their discount voucher, versus 30 per cent at the six-flavour stand. This is an astonishingly strong effect – and utterly counter to mainstream economic theory.

  • Fortunately, human forgetting follows a pattern. We forget exponentially. A graph of our likelihood of getting the correct answer on a quiz sweeps quickly downward over time and then levels off.

SSRN-The Empty Idea of Authority by Laurence Claus

This article presents an evolutionary account of law and government. The law of a human community is a self-generating, self-recognizing system of human communications that signals likely action within that community.
