Goal
Make better decisions with a method, not a gut feeling
You make better decisions by changing the process, not the analysis. Widen the options past whether-or-not, and test the assumption you are betting on with a disconfirming question or a small experiment. State your confidence as a number, get distance from the emotion of the week, and write how the decision failed before it does. Then judge the decision separately from the outcome. Six books supply the steps; a decision journal makes them stick.
What is really going on
You face a job, a flat, a hire or a treatment this year and you will decide the way you always have: a gut feeling, a pros-and-cons list, and a story afterwards about why it was right.
The same mistake keeps arriving in new clothes, because you review decisions by whether they worked rather than by how they were made.
Your decisions land on other people, and 'I had a good feeling' is not something you can defend to them or to yourself.
Five ideas from five books
- 1
Name the villain before you make the list
Chip and Dan Heath argue that most decisions go wrong before any analysis starts, because of four villains. Narrow framing shrinks the choice to whether-or-not. Confirmation bias turns research into a search for support. Short-term emotion lets the feeling of the week decide. Overconfidence makes you sure you know how the future will unfold. A pros-and-cons list defends against none of them: it accepts the options as given and is filled in by the person already leaning. The Heaths' WRAP process answers each villain in turn: widen your options, reality-test your assumptions, attain distance before deciding, and prepare to be wrong.

What you have spent has no vote
Rolf Dobelli describes the sunk cost fallacy: you stay in the project, the course or the investment because of what it has already cost. That money and time are gone whatever you decide, so they should have no vote. They vote anyway, because stopping turns a hoped-for recovery into a confirmed loss. The defence is one question: if you were starting today, knowing what you know and with nothing invested, would you choose this? If the answer is yes, continue. If it is no, the only reason you are still there is the cost, and the cost is not coming back.

Judge the decision, not the card
Annie Duke, a former professional poker player, argues that every decision is a bet: you choose with some information hidden, and then luck plays its part. A good decision can therefore lose and a bad one can win. Judging a decision by its outcome, which she calls resulting, teaches you to repeat lucky mistakes and abandon sound choices. Her alternative is four boxes instead of two: a good or bad decision, crossed with a good or bad outcome. Review a past decision by what you knew at the time, and change your process only when the decision itself was poor.

Say a number and check it later
In a forecasting tournament funded by the US intelligence community, Philip Tetlock found volunteers who outperformed professional analysts. They started from the base rate for cases like theirs, said 63 percent instead of 'probably', and later marked each number against what happened. That last habit builds calibration: when you say 70 percent, you are right about 70 percent of the time. Most people are overconfident, so their 90 percents come true noticeably less often than nine times in ten. Only a written, dated record shows you which way your own numbers run, and lets you correct them.

Write your own number first and reframe both ways
Daniel Kahneman and Amos Tversky documented two pulls on judgement. The first number you hear becomes an anchor, and later estimates adjust from it but not far enough, even when the number is plainly irrelevant. The wording of a fact changes the choice: a treatment with a 90 percent survival rate is accepted more readily than one with a 10 percent mortality rate. The defence is a step in the process. Write your own estimate before you hear anyone else's, then write the key fact once as a gain and once as a loss. If your choice flips, the frame was deciding.

Questions people ask
- How do I make better decisions?
- Change the process: widen the options, test the assumption, state a probability, get distance from the emotion, prepare to be wrong, and review the decision separately from the outcome.
- What is the best book on decision-making?
- Decisive by Chip and Dan Heath for the process, Thinking in Bets for the stance toward uncertainty, and Thinking, Fast and Slow for the psychology underneath.
- Is a pros-and-cons list a good way to decide?
- It describes your lean; it does not defend against any of the four errors the Heaths call villains (narrow framing, confirmation bias, short-term emotion and overconfidence). Keep it if you like, but add options, test assumptions and get distance first.
- How do I know if a past decision was good?
- Ask what you knew at the time, not what you know now. A good decision with a bad outcome is bad luck, not a mistake, and the process should not change.
