Predictably Irrational

Do you know why we so often promise ourselves to diet and exercise, only to have the thought vanish when the dessert cart rolls by?

Do you know why we sometimes find ourselves excitedly buying things we don’t really need?

Do you know why we still have a headache after taking a five-cent aspirin, but why that same headache vanishes when the aspirin costs 50 cents?

Do you know why people who have been asked to recall the Ten Commandments tend to be more honest (at least immediately afterward) than those who haven’t? Or why honor codes actually do reduce dishonesty in the workplace?
