Analytical Models vs Intuition
Analytical models excel in stable, data-rich environments. Intuition wins in complex, ambiguous situations with time pressure. Use both strategically.
All Frameworks Models Articles
Welcome to the complete index of every article in our Frameworks Models collection on When Notes Fly. This page lists all 28 articles in the section, organized alphabetically for easy reference. Each piece is researched, written by hand, and grounded in academic sources, professional practice, or empirical data. Whether you are diving into Frameworks Models for the first time or returning to find a specific article, the index below gives you direct access to the full collection within Concepts.
If you are new to Frameworks Models, we recommend starting with the foundational explainers and definitions before moving on to specific case studies, applied frameworks, and deeper analytical pieces. Articles are written for thoughtful readers who want substance over summary, with clear explanations of how ideas connect, where they come from, and why they matter. Use this index as a navigational map: skim the titles, read the short summaries, and click through to the pieces that draw your interest. Each article also links to related material so you can follow a thread of ideas across our entire Concepts library.

First Principles Thinking Explained
First principles thinking means breaking problems to fundamental truths, then building solutions from scratch. Reason from physics and logic, not analogy.
First Principles Thinking Explained
First principles thinking breaks problems down to fundamental truths, then reasons up from there. Instead of copying, ask 'what must be true?' first.
Framework Overload Explained
Framework overload happens when collecting mental models faster than applying them. Too many frameworks create decision paralysis, not better thinking.
How to Choose the Right Mental Model
Choose mental models by matching problem type: first principles for novelty, probabilistic thinking for uncertainty, systems thinking for complexity.
How to Think Like a Scientist in Everyday Life
Scientific thinking isn't just for labs. Learn how falsifiability, null hypothesis thinking, base rates, and pre-mortems can sharpen your decisions every day.
Inversion Thinking: Solving Problems by Reasoning Backwards
Inversion thinking: solve problems by asking what causes failure instead of how to succeed. The mental model used by Charlie Munger, Jacobi, and top decision-makers.
Problem-Solving Frameworks Used by Experts
Experts use frameworks like 5 Whys to find root causes, hypothesis-driven thinking to test assumptions, and issue trees to break problems into parts.
Strategic Frameworks That Actually Work
Strategic frameworks: SWOT analysis assesses internal and external factors, Porter's Five Forces analyzes competition, Blue Ocean creates new markets.
Systems Thinking Models Explained
Feedback loops connect outputs to inputs. Stocks accumulate; flows change them. Leverage points enable big impact from small changes. Delays create lag.
What Are Mental Models and Why They Matter
Mental models are thinking frameworks shaping perception and decisions. They create shortcuts but can blind you to alternatives. Update through feedback.
What Is Bounded Rationality
Herbert Simon's bounded rationality explains why humans satisfice rather than optimize. Learn about cognitive limits, heuristics as rational shortcuts, ecological rationality, and design implications.
What Is Deductive vs Inductive Reasoning
Deductive reasoning moves from general principles to specific conclusions. Inductive reasoning moves from specific observations to general principles. Learn the difference, how each is used, and where both fail.
What Is Design Thinking and How Does It Work
Design thinking explained: the Stanford d.school 5-stage process, IDEO's approach, real-world examples, how it compares to Agile, and when it fails.
What Is Fermi Estimation: How to Estimate Anything
Fermi estimation is the skill of making reasonable approximations from first principles, even with little data. Learn how it works, famous examples, and how to practice it.
What Is Game Theory: How Strategic Thinking Works
Game theory explains strategic decision-making when outcomes depend on others' choices. Learn Nash equilibrium, prisoner's dilemma, and real-world applications.
What Is Gamification: When Points and Badges Change Behavior
Gamification applies game mechanics to non-game contexts to drive behavior. Learn when it works, when it fails, and how to design it ethically and effectively.
What Is Lateral Thinking and How to Use It
Lateral thinking, coined by Edward de Bono, is a deliberate technique for solving problems from unexpected angles. Learn the key methods: Six Thinking Hats, random entry, and PO.
What Is Radical Transparency
Radical transparency at Bridgewater means recording all meetings and rating everyone publicly. Learn what works, what fails, and what other organizations can borrow.
What Is Strategic Thinking and How to Develop It
Strategic thinking is the ability to analyze complex situations, anticipate the future, and make decisions that create long-term advantage. Learn how to develop it.
What Is a Framework: How Structured Thinking Solves Problems
A framework is a structured set of principles that organizes thinking and guides decisions. Learn what frameworks are, famous examples, and how to choose and apply them.
What Is a Framework: When to Use One and When to Ignore It
Frameworks structure thinking and action, but they can also constrain it. Learn what frameworks are, how to evaluate them, and when to use them vs when to think from first principles.
What Is a Mental Model and How to Build a Better Toolkit
Mental models are thinking frameworks that help you reason clearly and make better decisions. Learn the most useful models and how to build your own toolkit.
What Is the Ikigai Framework
Ikigai is a Japanese concept for life purpose. Learn the real meaning vs the Western Venn diagram version, what longevity research shows, and how to find yours.
What Is the Monte Carlo Method
The Monte Carlo method uses random sampling to solve problems too complex for direct calculation. Learn its origins, how it works, and its applications in business and science.
What Is the Pareto Principle: The 80/20 Rule Explained
The Pareto Principle states that roughly 80% of outcomes come from 20% of causes, a pattern that appears across business, productivity, and nature.
When Frameworks Fail
Frameworks fail when context changes, oversimplification hides critical nuance, rigidity prevents adaptation, or wrong model is applied to problem.
Why Frameworks Simplify Complexity
Frameworks simplify complexity by reducing cognitive load, enabling pattern recognition across domains, and creating shared language for solving problems.
