The phenomena are real. Sunk cost fallacy, feedback loops, compounding — these operate on you whether you know about them or not. The question is whether you can see them.
What it is
Essential Concepts is a static knowledge base of named cognitive phenomena: mental models, thinking frameworks, and cognitive patterns. Each concept article covers one named pattern — the story, a precise definition, and where it breaks. A cross-domain alias layer connects the same pattern under the different names it carries across disciplines. And a handful of nexus articles argue how a cluster of concepts operates as a single unified mechanism.
The central thesis is that naming precedes mastery. You cannot reliably apply a pattern you have not named. The moment a concept gets a label — "anchoring bias," "Goodhart's Law," "somatic marker" — it becomes recognizable across domains. Without the name, you encounter the pattern but do not see it. With the name, you see it everywhere.
The project is built around three transitions. The first: unknown unknown to known unknown. You get the name. The ecosystem opens. The second: known unknown to known known — structured understanding, through cross-domain aliases, nexus articles, and worked examples. The third: known known to internalized intuition. That last transition is the user's own work; the site scaffolds the path to it.
The cross-domain alias layer
The primary structural differentiator is the alias layer. "OODA loop," "build-measure-learn," "PDCA cycle," and "hypothesis testing" are the same underlying pattern expressed in four domain vocabularies — military doctrine, startup methodology, manufacturing quality, and scientific method. The alias layer maps these connections explicitly. Someone searching from military doctrine discovers it connects to startup thinking and to scientific method. The concept is the node; the domain-specific names are the edges connecting it to existing knowledge.
This is also why the site works for the specific reader it was built for: the smart autodidact who has already read widely and keeps encountering the same pattern under different names without anyone connecting the dots.
Current state and what's next
Essential Concepts is live at concepts.battle-of-ideas.com. The original site at essentialconcepts.fun is retired — that domain wasn't renewed — but the project didn't end there; it was rebuilt. The current version is the same concept graph, re-authored and served as fast static pages: cross-linked, domain-aliased, and built so you can land on a pattern from whatever your own field calls it.
The live site is the full reference — the whole graph, browsable. A book is still a natural next form: the highest-leverage concepts arranged as a linear curriculum a reader can move through once and carry away a working framework. But that book would be a distillation of the live site, not a replacement for a retired one — the web version and a book are different products, and both are worth having.
The single highest-leverage action available right now is audience-building: the site has no email list, no publishing cadence, and no public knowledge that any of this exists beyond people I have personally directed there. The work is genuinely ready for audience. That asymmetry — strong asset, absent distribution — is the gap to close.
The twelve-essay book
The consolidation target is a twelve-essay book built around the highest-leverage concepts in the graph — the nine force multipliers (iterative processes, emotional-executive integration, assumption archaeology, systems thinking, and their kin) plus the three or four structural concepts that explain how the graph itself is organized. Short, dense, and designed for the reader who wants a working curriculum rather than a reference library.
Each essay in the book is drawn from an existing article. The material is already written; the book is a curation and sequencing problem. The live site stays as the full reference — the whole graph is a different product from a focused book, and both are worth having.
