Stop Being “Right”, Start Being Accurate: The Mindset Shift That Changes Everything
A deep dive into Thinking in Bets by Annie Duke
If you’ve ever looked back at a choice you made and thought “well, that worked out, so I guess I made the right call,” you’ve fallen into one of the most common thinking traps there is. Annie Duke, a former professional poker player with a PhD in cognitive psychology, spent years watching people (herself included) confuse good outcomes with good decisions. Her book, Thinking in Bets: Making Smarter Decisions When You Don’t Have All the Facts, is built around one simple but genuinely life-changing idea: every decision you make is a bet on an uncertain future, whether you realise it or not.
This isn’t a book about poker, even though poker is where Duke learned most of her lessons. It’s a book about how to think more clearly when you don’t have perfect information, which, if we’re honest, is nearly always. Whether you’re deciding on a career move, choosing a partner, negotiating a deal, or figuring out whether to trust a friend’s advice, you’re placing a bet. The question is whether you’re placing it wisely.
Below is a full breakdown of the book’s core ideas, plus ten practical tips you can start using this week, each with a real-world example so you’re not just nodding along and forgetting it by Friday.
Who Is Annie Duke, and Why Should You Listen to Her?
Annie Duke wasn’t always a poker player. She was on track to become an academic, studying cognitive psychology at the University of Pennsylvania under a renowned memory researcher, when a combination of health issues and financial pressure pushed her towards the poker table instead. What started as a way to pay bills turned into a two-decade career, including a World Series of Poker bracelet and millions of dollars in winnings.
What makes her perspective valuable isn’t the poker success itself. It’s that she approached the game as a scientist studying decision-making under uncertainty, using real money as the ultimate feedback mechanism. Poker, more than almost any other activity, punishes fuzzy thinking and rewards honest self-assessment. You can’t blame the dealer, the cards, or bad luck forever and still win money over the long run. Eventually, your decision-making has to improve, or you go broke.
That’s the lens she brings to everyday life: strip away the excuses, admit what you don’t know, and get comfortable making the best possible decision with incomplete information.
The Core Idea: Life Is Poker, Not Chess
Duke draws a distinction that sits at the heart of the entire book. Chess is a game of complete information. Both players can see the whole board, and if you lose, it’s almost entirely down to your own mistakes. Poker is different. You can play a hand perfectly and still lose, because you can’t see your opponent’s cards and you can’t control which cards come next.
Most of life looks a lot more like poker than chess. You rarely have all the information you need, and outcomes are shaped by a mix of the choices you make and pure chance. The problem is that our brains aren’t wired to separate the two. We tend to look at a good result and assume it proves we made a smart choice, and look at a bad result and assume we messed up, even when the opposite might be true.
Duke calls this tendency “resulting,” and unpacking it is where the real value of this book begins.
Why We Get This So Wrong: The Trap of Resulting
Imagine two people. One drives home after a few drinks and arrives safely. The other does the exact same thing and gets into a serious accident. Was the first person’s decision better than the second’s? Of course not. They made the same bet. One got lucky, the other didn’t.
Now scale that down to less dramatic, everyday choices. You take a job at a fast-growing startup that later folds. Does that mean taking the job was a bad decision? Not necessarily. It might have been an excellent decision with a poor outcome, because you couldn’t have known in advance that the company would run into trouble. Conversely, you might invest in a friend’s business on a hunch, it happens to succeed, and you walk away thinking your gut instinct is infallible, when really you got lucky.
Resulting is dangerous because it teaches us the wrong lessons. If we only judge decisions by how they turn out, we end up repeating bad decision-making processes that happened to produce good results, and abandoning good processes that happened to produce bad ones. Over time, this quietly makes us worse decision-makers while convincing us we’re getting better.
The fix isn’t to ignore outcomes altogether. Outcomes matter, and they’re useful data. The fix is to separate the quality of the decision from the quality of the result, and to judge each on its own terms.
10 Practical Tips From Thinking in Bets (With Real Examples)
1. Treat Every Decision Like a Bet
Start reframing your choices in the language of betting. Instead of asking “should I do this?”, ask “what am I betting will happen if I do this, and how confident am I really?” This small shift forces you to acknowledge uncertainty instead of pretending you know how things will turn out.
Example: Say you’re thinking about switching careers into a field you find exciting but have no experience in. Instead of framing it as “this is definitely the right move” or “this is definitely too risky,” frame it as a bet: “I’m betting that within two years, I’ll be earning comparable money and enjoying the work more, and I’d put that at roughly 60% likely.” Suddenly you’re thinking in terms of probability rather than certainty, which is a much more honest starting point.
Try this: Next time you’re facing a decision, write down the bet you’re actually making and assign it a rough percentage of confidence. Even a clumsy guess is more useful than false certainty.
2. Stop “Resulting”, Judge the Process, Not Just the Outcome
After you make a decision, resist the urge to grade it purely on how things turned out. Ask instead: given what I knew at the time, was this a reasonable bet to make?
Example: A manager promotes an employee based on strong performance and interview signals, and the employee later struggles in the new role. Bad decision? Maybe, maybe not. If the information available at the time genuinely pointed towards a good fit, the decision-making process might have been sound even though the outcome wasn’t. The manager should review what information was available, not just the fact that it didn’t work out, before overhauling their entire promotion process.
Try this: After any decision that goes badly, write down what you knew beforehand versus what you only found out afterwards. If the bad outcome came from information you couldn’t have had, that’s not a decision-making failure, it’s bad luck. Learn the difference.
3. Use the “Wanna Bet?” Test
Duke suggests a brilliantly simple trick for checking how much you actually believe something. Before stating an opinion with total confidence, ask yourself: would I bet money on this? If the answer is “actually, no, I wouldn’t risk £50 on that,” you’ve just discovered your real level of confidence, which is usually a lot lower than your tone of voice suggested.
Example: You tell a colleague “that project is definitely going to fail.” Before you say it, run the wanna-bet test. Would you put £100 on it? If you’d hesitate, your actual belief is more like “I think it’s fairly likely to struggle,” which is a very different, more honest statement.
Try this: For one week, mentally apply the wanna-bet test to any strong claim you’re about to make, especially in arguments. You’ll notice how often your confidence drops the moment real stakes are involved.
4. Build a Truthseeking Pod
Duke played poker with a tight-knit group who held each other accountable for sloppy thinking, rather than just cheering each other on. She calls this a “truthseeking pod”: a small group of people who genuinely want to help you see things clearly, even when that means telling you something you don’t want to hear.
Example: Instead of only running your business idea past friends who’ll say “sounds amazing!”, find two or three people who’ll ask hard questions: what happens if your main assumption is wrong? What are you not considering? A good pod member isn’t there to be negative, they’re there to pressure-test your thinking before reality does it for you.
Try this: Identify one or two people in your life who are willing to disagree with you constructively. Explicitly ask them to challenge your reasoning next time you’re making a big decision, rather than just offering support.
5. Run a Premortem Before Big Decisions
A premortem flips the usual review process on its head. Instead of waiting until after something fails to ask what went wrong, you imagine the failure in advance and work backwards from there.
Example: Before launching a new product, imagine it’s a year later and the launch has flopped. Write down every plausible reason why: poor timing, unclear messaging, wrong audience, underpriced, overpriced, and so on. This exercise often surfaces risks that pure forward-looking optimism tends to hide.
Try this: Before your next significant decision, spend fifteen minutes imagining it’s already failed, and list the most likely causes. Then decide whether any of those risks are worth addressing now.
6. Use Ulysses Contracts to Protect Future You
Named after Ulysses tying himself to the mast so he couldn’t be lured by the sirens, a Ulysses contract is a commitment you make now to stop your future self from making a poor decision under pressure or temptation.
Example: If you know you tend to panic-sell investments whenever the market dips, set a rule in advance (ideally with someone else holding you to it) that you won’t sell anything without waiting 48 hours and discussing it with a trusted friend first. You’re not trusting future-you to be rational in the moment, you’re building a structure that protects you from your own predictable weaknesses.
Try this: Think of one situation where you consistently make poor snap decisions (spending, arguments, quitting things too early) and design a simple rule or barrier that slows you down before you act.
7. Separate Luck From Skill, Honestly
Some outcomes are mostly skill, some are mostly luck, and most sit somewhere in between. Getting better at estimating where a given result falls on that spectrum is one of the most valuable skills Duke’s book teaches.
Example: A salesperson closes a huge deal. Was it their pitch, or was the client already leaning towards buying before the meeting even started? A salesperson who assumes it was all skill will repeat behaviours that might not actually work next time. One who honestly considers the role of luck will keep testing and refining, rather than getting complacent.
Try this: After your next win, genuinely ask what portion of that result came from factors outside your control. It’s not about being falsely modest, it’s about getting an accurate read so you can actually improve.
8. Practice Calibrated Confidence
Instead of speaking in absolutes (“I know”, “definitely”, “no way”), get in the habit of expressing your confidence as a rough percentage or range. This forces more honest thinking and makes it much easier to update your views when new information shows up.
Example: Rather than telling your partner “this restaurant will definitely be great,” say “I’d say there’s about an 80% chance we’ll enjoy it based on the reviews.” It sounds a little odd at first, but it keeps you honest, and if it turns out to be a disaster, you haven’t staked your entire credibility on being “right.”
Try this: For a few days, try attaching a rough confidence percentage to predictions you make out loud, even small ones. You’ll likely notice you’re less certain about more things than you assumed.
9. Seek Out Disconfirming Evidence on Purpose
Our natural instinct is to look for information that confirms what we already believe, and to dismiss or downplay anything that contradicts it. Duke calls this motivated reasoning, and it’s one of the biggest silent killers of good decision-making. The antidote is to deliberately go looking for evidence that you might be wrong.
Example: If you’re convinced a certain investment is a sure thing, don’t just read articles that support that view. Actively search for the strongest arguments against it. If you can’t find any credible counterarguments, your confidence is better earned. If you find several compelling ones, you’ve just saved yourself from a costly mistake.
Try this: Next time you hold a strong opinion, spend ten minutes specifically searching for the best case against it, not the weakest strawman version, the strongest one you can find.
10. Review Decisions on a Schedule, Not Just After Failures
Most people only sit down and analyse a decision when it goes badly. Duke recommends reviewing decisions regularly, regardless of outcome, so you’re learning from your wins as carefully as your losses.
Example: A poker player doesn’t just review the hands they lost. They review winning hands too, because sometimes a win comes from a genuinely poor decision that happened to get lucky, and if they don’t catch that, they’ll keep making the same mistake until the luck runs out.
Try this: Pick one area of your life (work decisions, financial choices, even relationship conversations) and set a monthly reminder to review two or three recent decisions, good and bad outcomes alike, purely on the quality of your thinking at the time.
Bringing It All Together
The single biggest shift Thinking in Bets asks you to make is this: stop chasing certainty you don’t have, and start getting comfortable making the best possible decision with the information available, while staying genuinely open to being wrong. That’s uncomfortable at first. Most of us like feeling certain, and admitting “I’m 65% confident” feels weaker than declaring “I know I’m right.” But Duke’s argument, backed by years at the poker table and in academic research, is that this discomfort is exactly where better thinking begins.
None of this means becoming a walking spreadsheet of probabilities, second-guessing every choice you make. It means building a handful of habits, checking your confidence honestly, resisting the urge to judge decisions purely by outcomes, surrounding yourself with people who’ll challenge your thinking, and treating being wrong as useful information rather than a personal failure. Do that consistently, and your decisions, in work, money, relationships, and everything in between, start to get noticeably sharper.
