Unseasonably pleasant weather inspires people to pay at a higher rate. Unseasonably cold weather, meanwhile, makes people cheat prolifically; so do heavy rain and wind.

Economics is, at root, the study of incentives: how people get what they want, or need, especially when other people want or need the same thing. Economists love incentives.

Incentives are the cornerstone of modern life.And understanding them – or, often, deciphering them – is the key to understanding a problem, and how it might be solved.

Knowing what to measure, and how to measure it, can make a complicated world less so.There is nothing like the sheer power of numbers to scrub away layers of confusion and contradiction, especially with emotional, hot-button topics.

The conventional wisdom is often wrong.And a blithe acceptance of it can lead to sloppy, wasteful, or even dangerous outcomes.

Correlation does not equal causality.When two things travel together, it is tempting to assume that one causes the other. Married people, for instance, are demonstrably happier than single people; does this mean that marriage causes happiness? The data suggests otherwise – that happy people are more likely to get married in the first place. As one researcher puts it, “if you’re grumpy, who the hell wants to marry you?”

Cocaine had never been a big seller in the ghetto: it was too expensive. But that was before the invention of crack. This new product was ideal for a low-income, street-level customer. Because it required such a tiny amount of pure cocaine, one hit of crack cost only a few dollars. Its powerful high reached the brain in just a few seconds—and then faded fast, sending the user back for more. From the outset, crack was bound to be a huge success.

when there are a lot of people willing and able to do a job, that job generally doesn’t pay well. This is one of four meaningful factors that determine a wage. The others are the specialized skills a job requires, the unpleasantness of a job, and the demand for services that the job fulfills.

Another barrier to thinking like a Freak is that most people are too busy to rethink the way they think – or to even spend much time thinking at all. When was the last time you sat for an hour of pure, unadulterated thinking?

Easy enough—as long as there are only a couple of variables. But with a couple of hundred variables, things get harder. Regression analysis is the tool that enables an economist to sort out these huge piles of data. It does so by artificially holding constant every variable except the two he wishes to focus on, and then showing how those two co-vary.

We have evolved with a tendency to link causality to things we can touch or feel, not to some distant or difficult phenomenon. We believe especially in near-term causes: a snake bites your friend, he screams with pain, and he dies. The snakebite, you conclude, must have killed him. Most of the time, such a reckoning is correct. But when it comes to cause and effect, there is often a trap in such open-and-shut thinking. We smirk now when we think of ancient cultures that embraced faulty causes—the warriors who believed, for instance, that it was their raping of a virgin that brought them victory on the battlefield. But we too embrace faulty causes, usually at the urging of an expert proclaiming a truth in which he has a vested interest.

There was perhaps no more attractive theory than the belief that smart policing stops crime. It offered a set of bona fide heroes rather than simply a dearth of villains. This theory rapidly became an article of faith because it appealed to the factors that, according to John Kenneth Galbraith, most contribute to the formation of conventional wisdom: the ease with which an idea may be understood and the degree to which it affects our personal well-being.
