Correct behavior should be the path of least resistance.

A design methodology for relocating resistance, so correct behavior becomes the easiest available behavior.

Correct behavior requires deliberate effort to overcome cognitive resistance.

System structure creates a net force toward the correct result.

The incline is a system metaphor, not a complete free-body diagram. Here, μ⁻¹ is conceptual notation. Inversion does not reverse a physical coefficient. It relocates resistance away from the correct path.

The principle

Every system has friction. The question is where it sits. Put it in front of the correct action and people route around it, quietly, at scale, and you get drift, rework, and a standards document nobody reads.

Cognitive friction behaves like static friction. The greatest resistance often appears before the correct action begins: remembering a rule, interpreting a standard, choosing a name, or deciding what comes next.

Poor workflows add kinetic friction too. They make people repeatedly reconstruct decisions the system already knows. Friction Inversion reduces both the effort required to begin and the drag required to continue.

Friction Inversion moves the resistance to the wrong side. The correct action becomes the default, the cheap one, the one that takes no thought. The incorrect action becomes the one that costs something: an extra step, a blocked export, a name the grammar cannot produce.

This is not automation and it is not enforcement. It is a decision about where difficulty belongs. Enforcement punishes people after the fact. Inversion makes the failure hard to reach in the first place.

I have been applying it since 2005 across DoD training systems, 3D production pipelines, design systems, and accessibility compliance. The essays below work it out in public.

Naming as Architecture IN REVIEW
Names emitted from tree position, not typed by hand. Under consideration at A List Apart.

Where it is applied

CourseForge

An AI-native LCMS. Names are emitted from position in the course tree, so a wrong name is not something you have to remember not to type. It is something the system will not produce.
