Public knowledge is undergoing a structural transformation.
A claim begins inside a serious discipline-medicine, economics, public policy-bounded by evidence, scope, and caveats. As it moves into public circulation, its form changes. It becomes simpler, louder, and more certain. Constraints fall away. The versions that travel farthest are shaped for ease of repetition, defense, and group alignment.
The Drift Model provides a clear, usable framework for seeing that transformation as a selection process-not a mystery, and not a personality diagnosis. It explains how claims lose their original structure under transmission pressure, why the same pattern repeats across domains, and where intervention still has leverage.
What this book gives youA five-stage model for how claims change function as they move: Serious Traditions → Meme Extracts → Folk Theories → Status Engines → Identity Systems.
A practical way to track what actually drifts: the claim bundle (proposition + scope + substrate + falsifiers), and how those constraints get shed over time.
A map of the selection environment that shapes modern knowledge: attention markets, algorithmic routing, context collapse, and governance pressures.
Four forensic case studies that make the mechanism visible across domains:
Health & wellness pipelines
Psychology & therapy pipelines
Politics & moral psychology pipelines
Organizations & KPI pipelines
A constrained toolkit for real work: stage-location guides, diagnostic checks, and writing/decision methods designed for high-pressure environments where revision has a cost.
You'll get the most value from this book if your work requires judgment under pressure-often before full clarity is available:
Researchers, analysts, and journalists working with contested claims where scope, updateability, and calibration matter.
Institutional stewards in policy, education, public health, governance, trust & safety, or communications who need decisions that hold up under scrutiny.
Organizational leaders operating inside KPI and incentive systems where measurement gradually substitutes for intent.
Writers, editors, and educators translating complex material into public-facing forms while preserving constraints.
This book supports two complementary uses:
Read for understanding: Parts I-III build the model and the selection environment.
Use under constraint: Part V functions as an operational reference with checklists and tools for rapid audits.
The Drift Model is descriptive rather than tactical. It supports diagnosis rather than optimization. It makes structural transformation visible-so you can locate where a claim's constraints were lost, what pressures selected the cheaper variant, and what it would take to make revision feasible again.
If you work in environments where claims must survive selection pressure, institutional scrutiny, and machine-legible retrieval, this book gives you a durable instrument for seeing clearly-before debates become identity infrastructure.
