Disasters are chains of small bad decisions; eat the sunk cost to break the chain and start a chain of good ones

Failure rarely comes from one catastrophic mistake. It is a sequence of individually-minor bad decisions, each one flowing from the last, that only look catastrophic when summed. The escape is psychological: accept the sunk cost so you stop protecting past choices, then make one small hard-but-good decision and trust it to lead to the next one. Success works the same way in reverse.
Origin
Horowitz learned this from a pilot he questioned about the JFK Jr. plane crash, who explained all crashes as ~17 sequential bad decisions. Horowitz mapped it onto both CEO failure and, inversely, onto how success actually accumulates.
Core principles
- 01No single decision in a disaster is that bad; the damage is in how they compound
- 02Each decision biases the next one, so a bad path self-perpetuates unless deliberately broken
- 03Sunk cost is the psychological hook that keeps you on the bad path
- 04Success is symmetric: a series of small, hard, low-impact-looking good decisions that eventually produce an outcome
How to run it
- 1
Locate the chain, not the single mistake
When something is going wrong, stop hunting for the one fatal error and instead trace the sequence of small decisions that led here. Each looked defensible in isolation.
Pro tip The narrative version people tell later ('then he did this smart thing') is almost never how it actually happened; ignore the clean story.

Take the sunk cost
Consciously write off what you've already invested in the current path. Refusing to abandon prior decisions is what keeps you sliding down the chain of bad ones.
Pro tip Ask 'if I were arriving fresh right now, would I choose this path?' rather than 'how much have I already put in?'
Watch out The first bad decision is often just prioritizing arrival over safety ('I need to get where I'm going'); watch for that pressure overriding conditions.

Make one small good decision and trust it forward
Do the next small, hard, seemingly-low-impact right thing, believing it will lead to the next one. Don't wait for a single heroic move.
Pro tip The hard part isn't complexity; it's that the good next step is small, difficult, and doesn't feel like it matters yet.
Watch out Expecting one big smart move to fix everything keeps you passive; the outcome is built from a chain of tiny wins.
In the wild
A pilot told Horowitz that plane crashes are a series of bad decisions, none bad alone: the pilot made arrival the priority, mistimed sunset so he flew in the dark, then pulled up while inverted. Roughly 17 sequential errors compounded into disaster.
→ Horowitz adopted 'take the sunk cost to get out of bad paths' as a core mental model for both avoiding CEO failure and building success incrementally.
Common mistakes
Protecting the sunk cost
Staying on a losing path to justify prior investment is precisely how one minor bad decision links to the next until the sum is fatal.
Waiting for the one big move
Believing success comes from a single genius decision makes you undervalue the small, hard, unglamorous next step that actually compounds into an outcome.
Is it for you?
Best for
Founders and operators stuck on a deteriorating path (wrong architecture, wrong strategy) who keep doubling down to justify past choices
Not ideal for
Situations where the current path is working and 'breaking the chain' would just be destructive novelty-seeking
From the transcript
“all plane crashes are a series of bad decisions and none of the decisions by themselves is that bad but when you add them up…”
“if psychologically you can take the sunk cost um then that gets you out of a lot of bad paths”
“a little good decision may be difficult but you have to believe it's going to lead to the next one”
