- Getting something extra “for free” feels better than getting the same for less.
- We’re heavily influenced by the first number.
- We’re terrified of extremes.
- We’re in love with stories.
- We do what we’re told.
- We let our emotions get the best of us.
- We’re easily made dumber by alcohol, time, decisions.
- We’re pained by transaction costs…

- We’re obsessed with the number 9.
- We’re compelled by a strong sense of fairness.
What’s a poetry recital by a behavioral economist worth? The students had no idea. That’s the point. I don’t know, either. That’s also the point. What’s a button-up shirt “worth”? What’s a cup of coffee “worth”? What’s a life insurance policy “worth”? Who knows! Most of us don’t. As a result, the shopping brain uses only what is knowable: visual clues, triggered emotions, comparisons, ratios, and a sense of bargain vs. rip-off. We’re not stupid. Just susceptible.
