Decision strategist, ex-pro poker player
Annie Duke wrote Thinking in Bets and Quit, is a special partner at First Round Capital, and won over $4 million in tournaments as a professional poker player. Her refrain is to take what's implicit and make it explicit. If you don't make it explicit, she says, you never find out when it's wrong. At First Round that meant turning the partners' intuitions into a rubric.

Name the signals that mean stop before you launch, and attach an action to each one while you still have no stake in the answer.
things go on way too long even like they're over budget and you've blown the timeline and when you finally shut it down you realize you should have done it a lot earlier
Decision Making
A good result is not evidence of a good decision. State the bet, put a number on your confidence, and record it before you know.
we don't actually know what the decision quality was, right, like all we know is that you had a good result
Monkeys and Pedestals
Originated by Astro Teller at Google X, Duke applies this model to quitting decisions. The metaphor: if your goal is to train a monkey to juggle flaming torches while…

If you are even considering quitting, you are likely already past the optimal quitting point.

Quitting on time will almost always feel like quitting too early.

Tackle the hardest, most uncertain part of the problem first before investing in the easy, known parts.
Project planning and resource allocation. Avoid building 'pedestals' (easy, comfortable work) when the 'monkey' (the hard, uncertain part) has not been validated.
Ask 'Would I start this today, knowing what I now know?' If the answer is no, that is a strong signal to quit.

Thinking in Bets: Making Smarter Decisions When You Don't Have All the Facts
Knowing about cognitive biases does not protect you from them. You need structural interventions (Ulysses contracts, kill criteria, truthseeking groups) to overcome biases in practice.
Duke emphasizes that the sunk cost fallacy is like a visual illusion: you can explain it, demonstrate it, and understand it intellectually, and you will still fall for…
Incorporating negative visualization alongside positive visualization makes you more likely to achieve your goals, not less.
Based on Gabriele Oettingen's 20+ years of research on mental contrasting, imagining obstacles alongside desired outcomes produces higher goal achievement than positive…
Idea validation
Never share your opinion first when soliciting feedback from others; let them answer independently before revealing your view.
Any situation where you are seeking outside perspectives on a decision. Sharing your opinion first contaminates others' views and produces false consensus.
How to Decide / Lenny's Podcast
You will always be better off seeking outside perspectives, but you must protect the independence of those perspectives by not sharing your own opinion first.
Outside views correct for the biases and blind spots inherent in any single perspective. However, sharing your opinion first creates anchoring effects and social…

locates the problem in the individual: resulting, motivated reasoning and hindsight bias drive decision errors, so you fix decisions by fixing personal process.
Donella Meadows and Peter Senge
argue behavior is produced by structure, feedback loops, incentives and delays, so blaming individual judgment misses the cause.
From Kill Criteria
Annie Duke
put a number on confidence. Hubbard pushes it further: anything that matters is observable and therefore measurable, and calibrated probability estimation makes even intangibles quantifiable.
Nassim Taleb
draws the opposite line. We systematically overestimate our ability to predict in complex domains, and a precise-looking model there is more dangerous than admitted ignorance because it manufactures false confidence.
