Analytical Models vs Intuition
Analytical models excel in stable, data-rich environments. Intuition wins in complex, ambiguous situations with time pressure. Use both strategically.
Welcome to the complete index of every article in our Frameworks Models collection on When Notes Fly. This page lists every article 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.
Most articles in this collection run between 1,500 and 3,000 words. We aim for the kind of explainer that holds up six months later: enough mechanism to be useful, enough nuance to be honest, and enough citation that you can verify the claims yourself. Where the research disagrees or the evidence is thin, we say so. Where a claim is well-established, we say that too. The goal is for you to leave with a working model you can apply, not a vibe you'll forget by Tuesday.
Bookmark this index — it gets fresh entries weekly. New articles are added at the top of the chronological feed and integrated into this alphabetical archive.

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...
Choose mental models by matching problem type: first principles for novelty, probabilistic thinking for uncertainty, systems thinking for complexity.
Scientific thinking isn't just for labs. Learn how falsifiability, null hypothesis thinking, base rates, and pre-mortems can sharpen your decisions...

The Monte Carlo method uses random sampling to solve problems too complex for direct calculation.
Experts use frameworks like 5 Whys to find root causes, hypothesis-driven thinking to test assumptions, and issue trees to break problems into parts.
Radical transparency at Bridgewater means recording all meetings and rating everyone publicly. Learn what works, what fails, and what other...
Strategic frameworks: SWOT analysis assesses internal and external factors, Porter's Five Forces analyzes competition, Blue Ocean creates new markets.
Feedback loops connect outputs to inputs. Stocks accumulate; flows change them. Leverage points enable big impact from small changes.

Herbert Simon's bounded rationality explains why humans satisfice rather than optimize. Learn about cognitive limits, heuristics as rational...
Mental models are thinking frameworks shaping perception and decisions. They create shortcuts but can blind you to alternatives.
Deductive reasoning moves from general principles to specific conclusions. Inductive reasoning moves from specific observations to general principles.
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.
Fermi estimation is the skill of making reasonable approximations from first principles, even with little data.
Lateral thinking, coined by Edward de Bono, is a deliberate technique for solving problems from unexpected angles.
Strategic thinking is the ability to analyze complex situations, anticipate the future, and make decisions that create long-term advantage.
A framework is a structured set of principles that organizes thinking and guides decisions. Learn what frameworks are, famous examples, and how to...
Mental models are thinking frameworks that help you reason clearly and make better decisions.
The Pareto Principle states that roughly 80% of outcomes come from 20% of causes, a pattern that appears across business, productivity, and nature.
Frameworks fail when context changes, oversimplification hides critical nuance, rigidity prevents adaptation, or wrong model is applied to problem.
