Decision Time
by Laurence Alison
A Summary by StoryShots
Your brain rewrites decisions in real time to avoid the pain of being wrong.
Introduction
That's the thesis of Decision Time by Laurence Alison and Neil Shortland. Two psychologists who spent decades advising police negotiators, military commanders, and corporate leaders discovered something counterintuitive: the decisions that go catastrophically wrong rarely involve bad information. They involve good people trapped in situations designed to break their judgment.
Stop Gathering More Information
When a decision feels impossible, your instinct is to hunt for more data. One more report. One more expert opinion. High-stakes decision-makers fall into this trap constantly because gathering information feels responsible, while making a call with incomplete data feels reckless. The quality of your decision rarely improves after you have 40% of the available information. Research on military commanders, ER doctors, and crisis negotiators shows the same pattern. Beyond that threshold, more data creates noise, conflicting interpretations, and more reasons to delay. The best decisions come from people who recognize when they've crossed the 40% line and commit. "Certainty is the enemy of good decisions. Clarity about your priorities is the foundation." If you've been delaying a decision until you know more, the real question is whether you're missing critical information or avoiding the discomfort of choice.
Cognitive Drift Changes Your Goals Without Permission
You think you make a decision, then act on it. But under stress, people unconsciously reframe their goals mid-decision to justify actions they've already started taking. A negotiator who initially prioritized saving a hostage's life will, after an hour of frustration, convince themselves the real goal was establishing authority. Your brain hates the tension of a plan not working, so it quietly edits your objectives to match what you're doing. By the time you notice, you're three moves deep into a strategy you never consciously chose. "We don't fail because we chose the wrong path. We fail because we forgot which destination we were aiming for." You've likely started a project with one clear purpose, then midway through, the purpose shifted to match the work you'd already invested in.
The Four-Question Filter for Every Decision
High-stakes decisions distill into four questions that stop cognitive drift before it starts. What am I trying to achieve. What will success look like one hour from now. What am I willing to sacrifice to get there. What would make me stop and reverse course. The first question anchors your real objective before pressure distorts it. The second forces you to define winning with brutal specificity. Not vague outcomes like "resolve the situation" but concrete markers like "hostage walks out unharmed." The third question is where most people lie to themselves. If you're not willing to sacrifice anything, you're not making a decision. The fourth question is your escape hatch. Decide now what evidence would prove you wrong, so you can exit before catastrophe. "Decisions made under pressure aren't about having the right answer. They're about knowing when to change your mind." When someone you know keeps second-guessing important decisions after they're made, send them this summary.
Final Summary
But the psychological trap called "horizon creep" will change how you see every negotiation, project, and conflict you've ever abandoned halfway through. Your brain slowly shifts what "good enough" means until you accept outcomes you'd have rejected at the start. We are putting together the full summary of Decision Time by Laurence Alison right now, with a visual infographic and animated video. The complete four-question framework, real scripts from hostage negotiations, and the premortem technique that identifies failure points before you commit will all be inside. This book is for leaders who make calls with incomplete information, parents navigating high-emotion conflicts, and anyone tired of regretting choices they made under pressure.
