Predictably Irrational: The Hidden Forces That Shape Our Decisions

by Dan Ariely

That’s a lesson we can all learn: the more we have, the more we want. And the only cure is to break the cycle of relativity.

Or, as Mark Twain once noted about Tom Sawyer, “Tom had discovered a great law of human action, namely, that in order to make a man covet a thing, it is only necessary to make the thing difficult to attain.”

We call this type of behavior herding. It happens when we assume that something is good (or bad) on the basis of other people’s previous behavior, and our own actions follow suit.

If you stopped to think about this, it would not be clear whether you should be spending all this money on coffee at Starbucks instead of getting cheaper coffee at Dunkin’ Donuts or even free coffee at the office. But you don’t think about these trade-offs anymore. You’ve already made this decision many times in the past, so you now assume that this is the way you want to spend your money. You’ve herded yourself—lining up behind your initial experience at Starbucks—and now you’re part of the crowd.

Descartes said, Cogito ergo sum—“I think, therefore I am.”

Socrates said that the unexamined life is not worth living. Perhaps it’s time to inventory the imprints and anchors in our own life. Even if they once were completely reasonable, are they still reasonable? Once the old choices are reconsidered, we can open ourselves to new decisions—and the new opportunities of a new day. That seems to make sense.

FREE! gives us such an emotional charge that we perceive what is being offered as immensely more valuable than it really is. Why? I think it’s because humans are intrinsically afraid of loss. The real allure of FREE! is tied to this fear. There’s no visible possibility of loss when we choose a FREE! item (it’s free).
