Quotes from Annie Duke

If you put individuals together in the right way, such that some individuals can use their reasoning powers to disconfirm the claims of others, and all individuals feel some common bond or shared fate that allows them to interact civilly, you can create a group that ends up producing good reasoning as an emergent property of the social system. This is why it's so important to have intellectual and ideological diversity within any group or institution whose goal is to find truth.

When we work toward belief calibration, we become less judgmental of ourselves.

There are many reasons why wrapping our arms around uncertainty and giving it a big hug will help us become better decision-makers. Here are two of them. First, "I'm not sure" is simply a more accurate representation of the world. Second, and related, when we accept that we can't be sure, we are less likely to fall into the trap of black-and-white thinking.

Certainly, in exchange for losing the fear of taking blame for bad outcomes, you also lose the unadulterated high of claiming good outcomes were 100% skill. That's a trade you should take. Remember, losing feels about twice as bad as winning feels good; being wrong feels about twice as bad as being right feels good. We are in a better place when we don't have to live at the edges. Euphoria or misery, with no choices in between, is not a very self-compassionate way to live.

Contrary to popular belief, winners quit a lot. That's how they win.

Experience can be an effective teacher. But, clearly, only some students listen to their teachers.

Making better decisions starts with understanding this: uncertainty can work a lot of mischief.

Optimism makes you less likely to walk away while not actually increasing your chances of success. That means that being overly optimistic will make you stick to things longer that aren't worthwhile. Better to be well calibrated. Life's too short to spend your time on opportunities that are no longer worthwhile.

The promise of this book is that if we follow the example of poker players by making explicit that our decisions are bets, we can make better decisions and anticipate (and take protective measures) when irrationality is likely to keep us from acting in our best interest.

Self-serving bias has immediate and obvious consequences for our ability to learn from experience.

Why might my belief not be true? What other evidence might be out there bearing on my belief? Are there similar areas I can look toward to gauge whether similar beliefs to mine are true? What sources of information could I have missed or minimized on the way to reaching my belief? What are the reasons someone else could have a different belief, what's their support, and why might they be right instead of me? What other perspectives are there as to why things turned out the way they did?

And this feeling that the result of the decision tells you something significant about the quality of the decision process is so powerful that even when the description of the decision is identical (you quit your job and take a new position), your view of that decision changes as the quality of the result changes.

When you are weighing whether to quit something or stick with it, you can't know for sure whether you can succeed at what you're doing because that's probabilistic. But there is a crucial difference between the two choices. Only one choice—the choice to persevere—lets you eventually find out the answer.

Incorporating uncertainty into the way we think about our beliefs comes with many benefits. By expressing our level of confidence in what we believe, we are shifting our approach to how we view the world. Acknowledging uncertainty is the first step in measuring and narrowing it. Incorporating uncertainty in the way we think about what we believe creates open-mindedness, moving us closer to a more objective stance toward information that disagrees with us.

At the moment that quitting becomes the objectively best choice, in practice things generally won't look particularly grim, even though the present does contain clues that can help you figure out how the future might unfold. The problem is, perhaps because of our aversion to quitting, we tend to rationalize away the clues contained in the present that would allow us to see how bad things really are.

By not quitting, you are missing out on the opportunity to switch to something that will create more progress toward your goals. Anytime you stay mired in a losing endeavor, that is when you are slowing your progress. Anytime you stick to something when there are better opportunities out there, that is when you are slowing your progress.

this idea of casting yourself into the future, imagining a failure, and then looking back to try to figure out why is called a premortem. Using a premortem is a great tool to help develop high-quality kill criteria.

what you value and what someone else values will be different. And your goals and values will inform your preferences for various outcomes. That means that how much you prefer a particular outcome relative to other possibilities will naturally be different from another person's preference for the same outcome relative to other possibilities.

If you're like most people, you were pretty surprised by these results. Most of us aren't aware of the wide range of what these words mean to different people. We assume that when we use a term, other people use it in the same way we do and mean the same thing we do.

When people result, they look at whether the result was good or bad to figure out if the decision was good or bad.

RESULTING A mental shortcut in which we use the quality of an outcome to figure out the quality of a decision.

What is true for grit is true for optimism. Optimism gets you to stick to things that are worthwhile. But optimism also gets you to stick to things that are no longer worthwhile. And life's too short to do that.

A necessary part of becoming a better decision-maker is learning from experience. Experience contains the lessons for improving future decisions. Resulting causes you to learn the wrong lessons.

Experience is supposed to be our best teacher, but sometimes we draw a connection between outcome quality and decision quality that is too tight.
