Steven Levitt and Stephen Dubner return to their favorite question: what really drives people to do what they do? Using data and economic reasoning, they reveal how incentives—often hidden or misaligned—shape behaviour in ways that defy common sense.

From the economics of prostitution to the misjudged risks of “drunk walking,” they show how intuition often clashes with evidence. Even terrorism and climate change get the Freakonomics treatment: stripped of ideology, examined through costs, trade-offs, and unintended consequences. Along the way, they expose how small tweaks or overlooked variables can flip outcomes entirely.

Levitt and Dubner’s message is refreshingly unsentimental: incentives rule, moralizing misleads, and clever measurement can outthink conventional wisdom. SuperFreakonomics isn’t just about odd statistics—it’s about cultivating a clearer lens on how the world actually works, and spotting the quiet levers that turn small insights into big results.
