A decision under pressure has three moments: before you commit, while pressure is actively bending your judgment, and after it's over, when you decide what to learn. Most people only ever manage the first, and half the time not even that. Here's the full system, in order.

The mechanism at a glance. Judge the decision at the fork, by the process. The outcome at the end has luck in it.
The losing player and the winning player look identical in any single hand. The difference is invisible: one of them ran a system before, during, and after the decision. The other just decided.

SHORT ANSWER
The Decision-Making OS is five free tools on this wiki, used in order across the three moments of any high-stakes choice. Before you commit: the 5-Question Pre-Bet Audit, which folds in expected-value thinking to check whether the bet is worth making at all. While pressure is live: the Tendler 7-Tilt taxonomy, to catch the emotional state distorting your judgment before it decides for you. After it's over: the Mental Hand History to structure what you learn, judged by process, not outcome, because a good decision can still lose, and a bad one can still win. This is poker's decision discipline, generalized to any choice made under pressure, not poker advice.

The problem
You're about to make a real decision: the job, the investment, the confrontation, the trade. You already want to decide well. What you need is help with the three specific places good intentions fail: you commit without checking whether the bet is actually worth it, something rattles you mid-decision and you don't notice, and afterward you grade the whole thing by how it turned out instead of whether the process was sound.
Each of those failure points already has its own page on this wiki, built from the same decision discipline professional poker players use to separate a winning career from a losing one. What's been missing is the map showing they're one system, not five unrelated tricks. This page is that map.
The mechanism
Every high-stakes decision has three moments, and each one fails a different way.
Before you commit, the failure is skipping the math. Intuition grabs the most vivid possible outcome, usually the scariest one, and reacts to it as if it were the only branch. The correction is the 5-Question Pre-Bet Audit, which forces the slow, deliberate brain online for 30 seconds before you commit, and folds in expected-value thinking, weighing each outcome by how likely and how valuable it is, instead of fixating on one.
While pressure is live, the failure is not noticing your own state. Something just went badly (a loss, a rejection, a mistake), and the next stretch of decisions gets made from a different, worse-informed state than the one before it. The Tendler 7-Tilt taxonomy diagnoses which of seven distinct emotional states is actually firing, because the generic advice to "calm down" fails when the correction doesn't match the specific belief underneath the tilt.
After it's over, the failure is grading the result instead of the decision. A sound choice can still lose; a reckless one can still win. That's resulting, and it quietly trains you toward worse decisions while feeling like learning. The Mental Hand History is the structured five-step debrief that catches what free-form reflection skips, precisely so the lesson you take away is about the process, not the scoreboard.
THE THREE MOMENTS
Before → During → After
Pre-Bet Audit + EV thinking, then Tilt diagnosis, then Mental Hand History judged by process over outcome. Each stage has its own free page below; this page is the map between them.
The operating system
STEP 01
Before: run the pre-bet audit
Thirty seconds, five questions, before you commit to anything with real stakes: your range of possibilities, the expected value, whether you're tilted, your best alternative, and the worst case you can live with. It's the checkpoint that catches a decision made on pattern-match instead of math.
If you only ever adopt one piece of this system, make it this one. It's the highest-yield 30 seconds in the whole OS.
STEP 02
Before: weigh it by expected value, not the scariest outcome
Inside the audit, question two is doing the real work: list the realistic outcomes, estimate how likely and how costly each one is, and pick the best weighted average, not the option that avoids the worst case, and not the one with the flashiest upside.
If you catch yourself treating a 5% outcome like a 90% one, that's the exact bias this step corrects.
STEP 03
During: name the tilt, don't just try to calm down
If something has already gone sideways and you're mid-decision, generic calm-down advice will fail if it doesn't match the specific belief driving the state. Diagnose which of the seven tilts is firing (Running-Bad, Injustice, Hate-Losing, Entitlement, Revenge, Desperation, or Mistake) and apply its specific correction, not a generic one.
Naming the type correctly is what tells you which fix to reach for. Get that right before you try to fix anything.
STEP 04
After: write the mental hand history
Ten to fifteen minutes, five fixed steps: the facts, the emotion, the tilt type, the flawed belief underneath, and the corrected belief in your own words. The fixed format is what makes the hard step (naming the flawed belief honestly) mandatory instead of optional, which free-form journaling always skips.
A single entry helps. A weekly review of several entries is where the real pattern recognition shows up.
STEP 05
After: judge the process, not the result
Once the debrief is written, grade it honestly: given what you knew at the time, was the call sound? That's a different question from whether it worked out, and conflating the two is resulting, the trap that teaches you to abandon good decisions because a good decision can still lose.
Ask "would I make the same call again with the same information?" If yes, it was a good decision, whatever the scoreboard says.
The five tools, in order
Each one is a full free page with its own printable card. This page is the index; they're where the actual protocol lives.
Two more pages apply this same discipline to a specific high-stakes decision rather than the general case: the Medication Decision Framework for a prescriber conversation, and salary negotiation for a comp conversation. Same OS, narrower input.
It's the map showing how five existing tools on this wiki fit together as one system, not a sixth tool. They go in the order you'd actually use them: an audit before you commit, a tilt check while pressure is live, and a structured debrief after, judged by process rather than result.
Where does this come from if I'm not a poker player?
The discipline comes from professional poker, but the mechanics have nothing to do with cards. Every high-stakes decision under pressure has the same three moments: a bet you're about to make, a nervous system that might be lying to you mid-decision, and a result you'll be tempted to over-learn from. The framework transfers; only the inputs change.
Do I need to use all five tools every time?
No. The Pre-Bet Audit is the one to run before any real decision. It takes 30 seconds. Tilt diagnosis only matters when you notice you're rattled. The Mental Hand History is worth the 10-15 minutes after anything that went badly enough to teach you something. Use the size of the decision to size the response.
How is this different from just trusting your gut?
Your gut is fast and usually fine for small decisions. It fails in three specific, predictable spots on big ones: it skips expected value in favor of the most vivid outcome, it can't tell you when it's compromised by tilt, and it grades itself by results instead of by whether the process was sound. The OS is built to catch exactly those three failure points, nothing else.

Where we get our research:
We cite peer-reviewed work by its DOI, so each reference above opens the article itself.
Where a framework's owner published a book rather than a paper, we name the author, year
and publisher and link the publisher's page. The most common are the
Gottman Institute's research,
Stephen Porges's The Polyvagal Theory (Norton, 2011)
and his 2023 reply to its critics,
and Fisher and Ury's Getting to Yes (Penguin).
Where we have no peer-reviewed article, we name the framework's author and say so.
