Truly eye-opening... There is almost no situation that Harford cannot dissect with his sharp economist's tools... economics has never been this cool' NEW STATESMAN

If humans are so clever, why do we smoke and gamble, or take drugs, or fall in love? Is this really rational behaviour? And how come your idiot boss is so overpaid?

We are rational beings after all.
