Practices that may help
- The Availability Heuristic: Why Memorable Feels Probable
The availability heuristic is the mental shortcut of judging how common or likely something is by how easily examples come to mind. Tversky and Kahneman identified it in 1973. It is adaptive in many everyday situations but systematically misfires for dramatic, recent, or emotionally vivid events — causing consistent over- and underestimation of real-world probabilities. - Check the actual base rate before trusting your intuitive estimate
When an event feels common or rare, look up how often it actually happens.
The Availability Heuristic: Why Memorable Feels Probable - Estimate conservatively and act on the conservative number
When uncertain, use a pessimistic estimate as your working assumption — not your best guess.
Margin of Safety - Build in slack — time, money, and energy buffers
Never plan to use 100% of your resources; leave a buffer for what you did not anticipate.
Margin of Safety - Availability Cascades: How Fears Spread and Inflate
An availability cascade, described by Timur Kuran and Cass Sunstein, is a self-reinforcing cycle in which a risk or concern becomes cognitively prominent not because it is objectively more likely but because it is repeatedly mentioned in social discourse — each mention making it more available, which prompts more mentions. The concept is analytically compelling and well-illustrated, though empirical isolation of the mechanism is limited. - Actively search for what you are not thinking about
The risks and options you cannot easily recall are at least as real as the ones you can.
The Availability Heuristic: Why Memorable Feels Probable - Build plans with slack for outcomes outside your model
Reserve capacity for events that are not in your risk model — because the most damaging events usually aren’t.
The Ludic Fallacy: When You Mistake Real Life for a Game - Ambiguity Aversion — Why Unknown Odds Feel Worse Than Bad Odds
Ambiguity aversion, demonstrated by Daniel Ellsberg's 1961 paradox, is the tendency to prefer bets with known probabilities over bets with unknown probabilities — even when expected value is identical or the unknown option may be better. It is driven by discomfort with Knightian uncertainty and systematically steers people away from unfamiliar but potentially high-value opportunities. - Correct for the recency amplification of availability
Recent events feel more probable than they are — apply an explicit recency discount.
The Availability Heuristic: Why Memorable Feels Probable - Check whether you’re demanding an unfair ambiguity premium
Estimate what you’d accept under comparable known-odds risk — if your bar is much higher for unknown odds, that gap is the bias.
Ambiguity Aversion — Why Unknown Odds Feel Worse Than Bad Odds
Does this sound like the set of challenges you might be facing?
- I’m about to make a real decision based on a gut sense that this kind of thing happens "all the time," and I’ve just realized I have no idea how often it actually happens
- I always tell myself it’ll take this long or cost this much, and somehow it always runs over and I’m scrambling
- Every hour of my day and every dollar of my budget is already spoken for, so the moment one small thing goes sideways the whole thing topples
- I’ve weighed all the options and risks I could think of, but I have this nagging worry that the thing that actually trips me up will be something that never even crossed my mind
- I’ve got a contingency plan for every risk I could name, and yet every time it’s the thing I never listed that actually knocks me over
