Decisive

Introduction

Chip and Dan Heath, authors of Made to Stick and Switch, turn to decision-making in Decisive, published in 2013. Drawing on psychology research, they identify four 'villains' of decision-making and offer a process to counter them.

Their framework is called WRAP.

Who should read this book?

Anyone making important decisions, from career choices to business strategy.

Helps with: Lead and grow at work, Think and decide more clearly

The central message

Use the WRAP process: Widen your options, Reality-test your assumptions, Attain distance before deciding, and Prepare to be wrong.

Key ideas and concepts

1. Widen your options

   Narrow framing, seeing a choice as 'this or not this', is a common trap. Ask what else you could do, and imagine your current options disappeared.

2. Reality-test your assumptions

   Counter confirmation bias by asking what would have to be true for each option, seeking disconfirming evidence and 'ooching': running small experiments.

3. Attain distance before deciding

   Short-term emotion clouds judgement. Ask how you'll feel in 10 minutes, 10 months and 10 years, or what you'd advise a friend.

4. Prepare to be wrong

   Overconfidence about the future is common. Plan for a range of outcomes and set 'tripwires' that prompt you to reconsider.

5. The four villains

   Narrow framing, confirmation bias, short-term emotion and overconfidence are the main enemies of good decisions.

Deeper analysis

Decisive is clear, practical and memorable. The Heaths take decades of research on decision-making and organize it into a simple process, WRAP, that readers can actually remember and use for career moves, business strategy or personal choices. Tools like the 10/10/10 test and tripwires are especially easy to apply.

Like their other books, it relies heavily on stories, some of which simplify the research behind them, and readers familiar with behavioural economics will recognize many ideas. A process can't remove uncertainty, and some decisions are too urgent for a full WRAP. Still, it's one of the most usable guides to deciding well.

Practical applications

• List more options for a decision.
• Seek disconfirming evidence.
• Use 10/10/10.
• Set a tripwire.
• Test small.
