Model dependence, spread and protective action

Use Defense and Transmission Modeling when a practice or variant keeps spreading, changes the conditions of its own continuation, or provokes a response whose consequences are unclear. Begin with the affected work and participants. A biological analogy does not establish the mechanism of an engineering or cultural case.

Working questionOpenResult
Does continued use help the work, and what would be lost if the support disappeared?DTM.1 - Distinguish Dependence, Cooperation and Parasitic UseA comparison of continuation, dependence and consequences for the named participants, with unresolved effects retained.
Why does a practice spread, stall or return after suppression?DTM.2, DTM.3 and DTM.4A law distinguishing exposure, uptake and reconstruction, connected to participant change and the conditions for continuation or return.
Does a changing aggregate reflect selection, interaction or diversion of a shared mechanism?DTM.5, DTM.6 or DTM.7The applicable decomposition or causal construction; a statistical contribution is kept separate from its explanation.
Which protective action changes the needed result, including harm or lost capability caused by the response?DTM.8 and DTM.9A comparison of action targets and response feedback, preserving residual activity, capacity, memory and effects on other participants.

Use the connected DTM entries when several of these results are needed together. The review-capacity example shows why a modeled protective effect still needs an operating contribution.
