- Feb 26, 2026ConceptsWhat Does "Framework" Actually Mean?A framework is a flexible scaffold that orients attention and organizes information without dictating the answer, which separates it from a model that explains, a method that prescribes steps, and a theory tested for truth rather than usefulness. The article sorts frameworks into conceptual, analytical, decision and process types, lists five design pitfalls, and names the anti-patterns: framework worship, theater and rigidity.
- Feb 20, 2026Concepts4 Moral Frameworks That Explain Every Ethical DilemmaGreene's functional MRI work compared the lever trolley case with the footbridge variant, where you push a man to stop the trolley. Outcomes are structurally identical, but the personal version activated emotion-associated regions far more strongly and subjects refused it. Impersonal dilemmas pull toward consequentialism, personal ones toward deontology. This compares consequentialism, deontology, virtue ethics and care ethics, then tests them on Milgram and Nuremberg.
- Feb 18, 2026ConceptsFramework Overload: Managing Mental Models EffectivelyMichael Porter complained in a 1996 Harvard Business Review essay that executives were filling in his own templates and calling the result strategy, with the tools replacing the thinking they were meant to support. Collecting frameworks costs almost nothing and feels like insight each time, so libraries grow past the point of use. The three traps: collection without depth, retrieval failure under pressure, and paralysis when frameworks contradict.
- Feb 17, 2026ConceptsStrategic Frameworks That Actually WorkSix strategic frameworks, with the question each one answers and the conditions under which it misleads: Five Forces struggles with platforms, SWOT collapses into list-making, value chain analysis breaks down for software. McGahan and Porter's 1997 study of Compustat segment data found business-unit factors explained about 32 percent of profitability variance against roughly 19 percent for industry effects, which argues for starting with your own capabilities.
- Feb 17, 2026ConceptsProblem-Solving Frameworks Used by ExpertsEight frameworks with the problem type each one fits, plus where each breaks: 5 Whys, Ishikawa fishbone, MECE, issue trees, hypothesis-driven investigation, first principles, pre-mortem and 80/20. The research behind the structure-first habit is De Groot's 1965 chess study, which found grandmasters searched fewer moves than weaker players, not more. Their edge was scoping to a few promising candidates and going deep on those.
- Feb 17, 2026ConceptsWhat Are Mental Models and Why They MatterA mental model is a simplified representation of how something works, and it decides what you notice before reasoning begins. The clearest evidence that model quality beats raw memory comes from Chase and Simon's chess research: shown real positions for five seconds, masters reproduced about 16 pieces to a novice's four, but on randomly arranged boards managed only about 3-4. Also traces model failures at NASA, in 2008 risk models, and at Toyota.
- Feb 16, 2026ConceptsWhen Frameworks FailFrameworks fail in patterns you can spot in advance, among them context mismatch, rigidity bias, static models in changing markets, and mistaking the map for the territory. The Gaussian copula is the sharpest case: David Li's correlation formula was calibrated on corporate bond defaults in stable credit conditions, then applied to mortgages in a housing market that had never fallen nationwide, with his own warning left out.
- Feb 15, 2026ConceptsFrameworks and Complexity: Simplifying Decision-MakingHerbert Simon won the 1978 Nobel Prize in Economics for showing that real decision-makers cannot optimize and must satisfice, and his point was not that this is a flaw to overcome. Because working memory holds roughly four items, complex problems exceed capacity unless structured. Frameworks chunk information so a physician reads fever, white cell count and localized pain as one concept. The six mechanisms that do the simplifying, each paired with how it fails.
- Feb 1, 2026ConceptsUniversal Principles That Apply Across DomainsWest, Brown and Enquist showed mammalian metabolic rate scales as body mass to the 3/4 power, and West later found city productivity and innovation scale superlinearly with population, at roughly the 1.15 power. The same fractal branching logic governs trees, circulatory systems and river basins. Ten principles covered: compound effects, leverage, feedback loops, diminishing returns, opportunity cost, inertia, path dependence, scale effects, conservation and thresholds.

- Nov 30, 2024ConceptsWhat Is the Pareto Principle: The 80/20 Rule ExplainedPareto observed in 1896 that roughly 80% of Italian land was held by 20% of the population; Joseph Juran generalized it into the vital few and the trivial many for manufacturing quality in the 1940s. Fenton and Ohlsson, in IEEE Transactions on Software Engineering, found about 20% of code modules held roughly 80% of defects, and that those modules could be flagged in advance by complexity metrics. The article is equally clear on why the low-value 80% is rarely separable.
- Nov 18, 2024ConceptsWhat Is a Framework: Principles for Structured ThinkingDemographic segmentation and asking customers what they wanted produced nothing useful. Reframing the question to what job the customer hires a milkshake to do revealed morning commuters buying something to last a long drive, competing against bananas and bagels rather than other milkshakes. The page separates frameworks from models, methodologies and processes, and is blunt that domain mismatch, like applying Five Forces to a platform business, is the common failure.
