Introduction: Why This Isn’t A Poker Book
A Bet is really a decision about an uncertain future. (pg 3)
Thinking in bets starts with recognizing that there are exactly two things that determine how our lives turn out: the quality of our decisions and luck. (pg 4)
Learning to recognize the difference between decision quality and luck is what thinking in bets is all about. (pg 4)
Chapter 1: Life is Poker, Not Chess
Hindsight bias is the tendency, after an outcome is known, to see the outcome as having been inevitable. (pg 10)
If we aren’t wrong just because things didn’t work out, then we aren’t right just because things turned out well. (pg 35)
A great decision is the result of a good process, and that process must include an attempt to accurately represent our own state of knowledge. (pg 27)
“I’m not sure” does not mean there is no objective truth. It means that we treat our beliefs as works in progress, as under construction. (pg 27)
Chapter 2: Wanna Bet?
Every decision commits us to some course of action that, by definition, eliminates acting on other alternatives. (pg 44)
In most of our decisions, we are not betting against another person. Rather, we are betting against all the future versions of ourselves that we are not choosing. (pg 45-46)
“Wanna bet?” triggers us to engage in a vetting process for our beliefs, reminding us that our beliefs are works in progress. (pg 66)
Incorporating uncertainty into the way we think about our beliefs is the first step in measuring and narrowing it. (pg 70)
There is no sin in finding out there is evidence that contradicts what we believe. The only sin is in not using that evidence to refine our beliefs. (pg 71)
Chapter 3: Bet to Learn: Fielding the Unfolding Future
The more evidence we get from experience, the less uncertainty we have about our beliefs and choices. (pg 80)
Our lives turn out as a result of two things: the influence of skill and the influence of luck. (pg 82)
Self-serving bias makes us take credit for good outcomes and blame bad outcomes on luck. (pg 89)
Most of the variance in happiness comes from how we compare ourselves with others, not objective circumstances. (pg 104)
Treating outcomes as bets makes us more compassionate toward others and encourages learning. (pg 114)
Chapter 4: The Buddy System
Groups improve thinking when members are accountable to a collective interest in accuracy. (pg 129)
Accuracy, accountability, and diversity wrapped into a group’s charter contribute to better decision-making. (pg 151)
Chapter 5: Dissent to Win
Outcome-blind analysis reduces bias by hiding results until all decisions are made. (pg 166)
Skepticism is about asking why things might not be true rather than why they are true. (pg 169)
Expressing uncertainty invites helpful information and dissenting opinions. (pg 172-175)
Chapter 6: Adventures in Mental Time Travel
Improving decision quality is about increasing our chances of good outcomes, not guaranteeing them. (pg 180)
Our vision of the future is a creative reassembling of our past experiences. (pg 183)
Moving regret in front of a decision influences better choices and helps us treat ourselves compassionately. (pg 189)
Premortems - imagining failure before it happens-help uncover potential risks and reduce hindsight bias. (pg 222-224)
Extra Notes
We win bets by striving to calibrate our beliefs and predictions about the future to more accurately represent the world.
Declaring uncertainty makes us more credible communicators.
Outcomes are feedback: “Experience is not what happens to a man; it is what a man does with what happens to him.”
Self-serving bias and binary thinking are natural cognitive traps; thinking in bets helps us mitigate them.
The Rashomon Effect reminds us that different interpretations of the same event are normal and shape beliefs.
