Evaluating decisions based on their outcomes rather than the quality of the process leads to poor judgment and superstitious thinking.

“If you judge decisions only by outcomes, you learn the wrong lessons from your own life. You abandon good strategies because they had bad results. You double down on bad strategies because they happen to work. You become superstitious instead of strategic.”

The quality of decision-making is more critical for great investors than technical skills, and they should use probabilistic tools like base rates, pre-mortems, and decision logs.

“what i came to realize no probably 15 or 20 years ago was what differentiates good to great investors has little to do with their sort of technical skills like their ability to build spreadsheets or whatever and much more about their temperament and in particular their ability to make decisions”

One should separate the quality of a decision from its outcome, as good decisions are based on available data rather than the unpredictability of results.

“Good decisions are simply based on the data that's in front of us. Would a good decision-maker choose what I chose? If the answer is yes, then you made a good decision. So, suddenly we're not paralyzed anymore.”

The quality of a decision should be evaluated based on the process and available information, rather than the final outcome.

“The simple reality is that Pete Carol got unlucky he had control over the quality of the play called decision but not over how it turned out he called a play that had a high probability of ending with either a game-winning touchdown or an incomplete pass but sometimes good decisions can lead to bad ”

Effective decision-making requires separating one's internal process from the external outcomes, especially in high-uncertainty environments.

“you can actually start to figure out okay how do i look at my decision process and how do i separate it completely from the outcome because there are elements i control right i control how i play”

Waiting for 100% certainty is unnecessary; decisions should be made once 51% certainty is reached.

“you have to get to 51% certainty or as close as you can to 51 50% certainty and make the decision with the peace of mind that you made that decision in that moment with all of the available evidence and you have to let it go”

Individuals should take action once they are 70% ready, as aiming for 100% readiness often leads to missing key opportunities.

“It said if you're 70% ready you should take action. If you're a hundred percent ready you've already missed the opportunity.”

Relying too heavily on mentors can lead to decision paralysis, making it better to trust one's gut and act.

“I think that ambitious people have this mindset like I want to learn from the smartest people because that makes sense, right? So they gather all the mentors that they have possible and then they enter paralysis when it comes to decision-m so they ask all the mentors around them um instead of listen”

People should avoid being indecisive and instead take action, as most decisions are reversible and acting leads to greater happiness.

“Happy people take more action while other miserable people wait for the right decision.”

Clarity is achieved through action rather than excessive deliberation.

“Clarity comes from action, not thought. So, when you're sitting around, you got a decision making, like I got to think about it more, think about it more, think about it more. Actually, that's not where clarity comes from. Clarity comes from taking an action.”

She argues that in order to improve decision quality, people must make implicit intuitions explicit so they can identify when those intuitions are wrong.

“it's so incredibly necessary in improving decision quality to take what's implicit and make it explicit it's not that intuition is crap your intuition is sometimes right if you don't make it explicit then you don't get to find out when it's wrong”

People can improve their decision-making by recognizing cognitive biases and implementing systematic routines to analyze their intuitions.

“we need to recognize our intuitions but then we need to analyze them in a logical manner rather than just kind of going with them”

Big life decisions should not be made impulsively, but through a deliberate, research-backed framework that encourages thinking beyond the short term and avoids common human biases.

“when it comes to bigger decisions, decisions where money and love are on the line, which is most of the big ones that we make in life in terms of, you know, do I marry this person? Do we want kids? Where should we live? You know, is this still the right person for me, right? many years into a marria”

Effective decision-making requires Bayesian reasoning, which allows for the integration of prior knowledge and expert judgment with new data to handle uncertainty.

“what you did have was judgment so that took us back to probabilistic reasoning rather than statistical of course we reduce statistics and use numbers but within that context so it was it was much much more”

Bayesian modeling provides a necessary framework for making reliable decisions in complex, real-world systems where traditional statistical data is insufficient or absent.

“so you needed some way of combining the little bit of data that you do have with sort of expert judgment about the sort of the process of design and stuff like that and that's where kind of like the B start come comes in”
