20 proven mental models for better decision-making
Evaluate decisions by considering how you'll feel about them at three time horizons: 10 minutes, 10 months, and 10 years from now. Created by Suzy Welch, this framework fights short-term emotional bias.
Jeff Bezos's framework: Project yourself to age 80 and look back on your life. Which choice would you regret NOT making? This framework is especially powerful for decisions involving risk and opportunity.
Go beyond first-order consequences ("And then what?"). Most people stop at the immediate effect of a decision. Second-order thinkers consider the cascading chain of consequences.
Instead of asking "How do I succeed?", ask "How would I guarantee failure?" Then avoid those things. Charlie Munger's favorite mental model — solving problems backwards often reveals hidden risks.
An enhanced version of the classic pros/cons list where each factor is weighted by importance (1-10). This forces you to prioritize what actually matters rather than counting items.
Categorize tasks/decisions by urgency and importance into four quadrants: Do First (urgent + important), Schedule (important, not urgent), Delegate (urgent, not important), Eliminate (neither).
Ask: "Knowing what I now know, would I get into this situation again?" If no, the next question is "How do I get out, and how fast?" This fights sunk cost fallacy directly.
Amazon's framework: Is this decision reversible (two-way door) or irreversible (one-way door)? Two-way doors should be made quickly by individuals. One-way doors deserve careful, slow analysis.
Imagine a smart, objective outsider — someone with no emotional stake — looking at your situation. What would they advise? This depersonalizes the decision and reduces emotional bias.
Every choice has a hidden cost: what you give up by not choosing the alternative. This framework forces you to explicitly identify and weigh what you're sacrificing with each option.
Before you start, imagine the project has already failed spectacularly. Now work backwards: what went wrong? Developed by psychologist Gary Klein, this surfaces risks that optimism hides.
Chip & Dan Heath's 4-step process to counter the four villains of decision-making: narrow framing, confirmation bias, short-term emotion, and overconfidence. WRAP = Widen, Reality-test, Attain distance, Prepare.
Break a problem down to its most fundamental truths and build up from there, rather than reasoning by analogy. Used by Elon Musk to rethink everything from rocket costs to battery prices.
80% of outcomes come from 20% of causes. Instead of trying to optimize everything, identify and focus on the vital few inputs that drive most of the results.
Deliberately assign someone (or yourself) to argue against the preferred decision. This structured dissent prevents groupthink and surfaces weaknesses before they become real problems.
Observe, Orient, Decide, Act — then loop. Developed by military strategist John Boyd, this framework prioritizes speed of iteration over perfection. The faster your OODA loop, the more adaptive you become.
John Rawls's thought experiment: Make the decision as if you didn't know which position you'd hold in the outcome. This removes self-interest and reveals the fairest choice.
Choose the first option that meets your minimum criteria rather than exhaustively searching for the "best" option. Herbert Simon's concept: "good enough" often beats "optimal" when search costs are high.
Edward de Bono's parallel thinking method: examine a decision from six distinct angles (facts, emotions, caution, benefits, creativity, process) one at a time. Prevents mixed-mode thinking chaos.
Score each option on Impact (1-10), Confidence (1-10), and Ease (1-10), then average. A quick, quantitative way to rank competing ideas or features when you need to prioritize a backlog.
