Here it is. Use it well.
12 mental models for people who make decisions that matter. Yours to keep, share, or mark up until the margins run out.
I built this because most mental model lists are just… lists. Twelve words per model, a fancy diagram, and you’re left wondering how any of it applies to the actual meeting you have in forty minutes.
This Toolkit is different. Each model is paired with the specific situation it was built for — the kind of decision where thinking clearly is the only advantage you have.
Read it once for the overview. Then keep it nearby for the hard calls. That’s what it’s for.

01
First Principles Thinking
Strip away assumption until you hit bedrock. The only model that actually produces new ideas.
02
Second-Order Thinking
The obvious consequence is already priced in. It’s the consequence of the consequence that matters.
03
Inversion
Don’t ask how to succeed. Ask how to guarantee failure — then don’t do that.
04
The Pareto Principle (80/20)
Roughly 80% of your outcomes come from 20% of your inputs.
05
Opportunity Cost
Every choice you make costs you the value of the next best alternative you didn’t choose
06
Margin of Safety
Always build a buffer into your plans, timelines, and budgets to absorb the inevitable shocks, errors, and bad luck.
07
Occam’s Razor
Among competing explanations or solutions, the simplest one with the fewest assumptions is usually the correct one.
08
Hanlon’s Razor
Never attribute to malice that which is adequately explained by stupidity, incompetence, or oversight.
09
Confirmation Bias Avoidance
Actively seek out information that contradicts your existing beliefs, rather than selectively hunting for data that proves you right.
10
Circle of Competence
Know exactly what you understand, know exactly what you don’t, and ruthlessly avoid playing games outside your boundaries.
11
The Map is Not the Territory
The models, metrics, and dashboards we use to understand reality are just abstractions; they are never perfectly accurate reflections of reality itself.
12
Systems Thinking (Feedback Loops)
View your product or business not as isolated parts, but as an interconnected web where every action generates a feedback loop that either stabilizes or accelerates the system.
