Coaching practices for Expected Value of Information
Describe almost anything you are working through and IX Coach finds the practices whose real-world fit is closest. For Expected Value of Information, these are the strongest matches in the current practice library.
Does this sound like the set of challenges you might be facing?
- I keep telling myself I just need to research a little more before I decide
- The math says this bet is worth taking, but if it goes wrong the loss would genuinely wreck me
- I make these probability guesses in my head
- This is a one-way door
- I keep playing out this decision in my head as if there’s just one way it goes
Practices that may help
- Calculate the expected value of gathering more information
Before researching further, ask whether the additional information is actually worth the cost to obtain.
Expected Value Thinking: Deciding Under Uncertainty - Expected Value Thinking: Deciding Under Uncertainty
Expected value thinking multiplies each possible outcome by its probability and sums the results, giving a single number that represents the average payoff of a decision. It is the mathematical foundation of rational decision-making under uncertainty — well grounded in decision theory — but it has real limits: probabilities are often uncertain, outcomes are not always quantifiable, and raw expected value ignores risk aversion that can be legitimate. - Adjust raw expected value for risk aversion on large stakes
A 50% chance of losing everything is not equivalent to a certain 50% loss — adjust for your actual risk tolerance.
Expected Value Thinking: Deciding Under Uncertainty - Keep a decision journal to score your EV estimates
Log your probability estimates and payoff predictions, then compare them to what happened.
Expected Value Thinking: Deciding Under Uncertainty - Use maximin reasoning for high-stakes, irreversible decisions under ambiguity
Choose the option whose worst plausible outcome is most survivable — when you can’t compute expected value, optimize the floor.
Ambiguity Aversion — Why Unknown Odds Feel Worse Than Bad Odds - Enumerate scenarios and their probabilities before deciding
Write down each meaningful outcome, assign a probability, and compute the weighted total.
Expected Value Thinking: Deciding Under Uncertainty - Estimate in ranges, not point estimates
Instead of "my estimate is 500," say "I think it is between 200 and 2000."
Fermi Estimation - Track your information exposure and adjust for its biases
What you see most is not what happens most — audit your information diet.
The Availability Heuristic: Why Memorable Feels Probable - Track your estimates and calibrate
Compare your Fermi estimates to actual figures when you can, and use the gap to improve future estimates.
Fermi Estimation - Update beliefs by degrees, not wholesale
Treat new information as evidence that shifts probabilities, not as proof that changes everything.
