Great Mental Models Vol 1 Flashcards
(96 cards)
What is the core idea of the mental model ‘The Map is Not the Territory’?
Models are simplified abstractions of reality. They are useful but not perfectly accurate. Don’t confuse the representation with the real thing.
What tool helps apply the model ‘The Map is Not the Territory’ effectively?
Continuously compare the model to real-world feedback. Ask: ‘Does this still reflect reality?’
What defines your Circle of Competence?
It’s the domain where you have deep experience and sound understanding—where your decisions consistently yield reliable results.
How do you identify and stay within your Circle of Competence?
Track your decisions, reflect on outcomes, and seek candid feedback. Be honest about what you don’t know.
What tool can grow your Circle of Competence?
Use a decision journal to record assumptions, results, and lessons learned.
What is First Principles Thinking and why is it powerful?
It breaks problems down to their foundational truths and builds solutions from scratch—removing assumptions and analogies.
What tools help apply First Principles Thinking?
Use the Socratic Method to question deeply, and the Five Whys to identify root causes.
What is Second-Order Thinking?
It’s the discipline of considering the ripple effects and long-term consequences of your actions.
What’s a tool for using Second-Order Thinking?
Ask repeatedly: ‘And then what?’ to map out consequences beyond the first outcome.
What is Probabilistic Thinking?
Making decisions based on the likelihood of various outcomes—not assuming certainty.
How do you practice Probabilistic Thinking?
Use base rates, expected value, and scenario planning to assign and act on probabilities.
What is the mental model of Inversion?
Solving problems by asking the reverse: ‘What would guarantee failure?’ and avoiding those actions.
How can Inversion be applied?
Use prompts like: ‘What could cause this to go terribly wrong?’
What does Occam’s Razor suggest?
Prefer the simplest explanation that accounts for the facts. Avoid unnecessary complexity.
How do you apply Occam’s Razor in practice?
Eliminate over-engineered theories unless strong evidence supports them.
What does Hanlon’s Razor warn us against?
Don’t assume malice when a simpler explanation (like ignorance or error) will do.
What’s a key insight from using Hanlon’s Razor?
Reserve judgment. Ask: ‘Could this be a mistake rather than an attack?’
What is falsifiability in thinking and science?
A claim is only scientific if it can be proven false. If it can’t be tested, it’s not useful for understanding reality.
What tool does falsifiability give us?
Ask: “What evidence would prove this wrong?” If no such evidence exists, be skeptical of the claim.
What is the difference between necessity and sufficiency?
A necessary condition must be true for something to occur. A sufficient condition guarantees it will occur.
What thinking error does this model help avoid?
Confusing “must be” with “is enough.”
Example: Fire needs oxygen (necessary), but oxygen alone isn’t enough to cause fire (not sufficient).
What’s the difference between causation and correlation?
Correlation is when two things happen together. Causation is when one thing causes the other to happen.
What’s a tool for distinguishing the two?
Use experiments, controls, or time sequencing to test if one variable directly affects the other.
What is the “latticework of mental models” and why is it important?
It’s a network of core ideas from different disciplines that interact to provide multiple perspectives. Thinking in a multidisciplinary way reduces blind spots and enhances decision-making.
