Decisive — How to Make Better Choices in Life and Work

Chip Heath and Dan Heath — the authors of Switch and Made to Stick — bring their characteristic formula to decision-making: identify the core cognitive errors, name them memorably, and offer a practical framework for overcoming them. Decisive is structured around four “villains” of good decision-making and a four-step antidote called WRAP: Widen your options, Reality-test your assumptions, Attain distance before deciding, and Prepare to be wrong. The framework is deliberately simplified, designed to be remembered and used under pressure rather than consulted in a textbook, and it succeeds on those terms.

The first villain — narrow framing — is the most common and perhaps the most damaging. Most decisions arrive pre-packaged as binary choices: stay or go, hire or don’t, invest or pass. The Heath brothers argue that this framing is rarely imposed by circumstances; it is usually a failure of imagination. The solution they propose is the “vanishing options test”: ask yourself what you would do if your current options were both off the table. The question reliably surfaces alternatives that were invisible within the original frame. A manager deciding whether to fire an underperforming employee who imagines that firing and not firing are both impossible suddenly discovers the option of a performance improvement plan, a role change, or a structured conversation that hadn’t been considered.

The second villain, confirmation bias, is addressed through the technique of “reality-testing assumptions” — specifically through deliberate efforts to seek disconfirming evidence. The Heath brothers borrow the concept of the “pre-mortem” from Gary Klein and the idea of seeking out someone who has already solved your problem from various management traditions. Most useful is their emphasis on asking “what would have to be true for the opposing view to be correct?” — which forces you to genuinely engage with counter-evidence rather than merely acknowledging its existence.

The third and fourth steps — attaining emotional distance and preparing to be wrong — are less original but well-executed. The 10-10-10 technique (how will I feel about this in 10 minutes, 10 months, 10 years?) is a simple and effective way of breaking the grip of short-term emotion on consequential decisions. The preparation for failure section draws on pre-commitment devices and the creation of what the Heath brothers call “tripwires” — predetermined conditions under which you will reassess rather than simply continuing. Decisive is less intellectually ambitious than Kahneman’s Thinking, Fast and Slow, but it is more immediately teachable, and the WRAP framework is the kind of simple, memorable structure that actually changes behaviour in organisations.
