ETYMOLOGY

COINED BY
Don Norman / Richard Sennett / Formalized by Chromologium
Calibrated physical or procedural resistance intentionally engineered into an interface to induce mindful evaluation, craft agency, and error prevention.
Knurled dial drag thresholds, multi-axis spring gates on critical exports, and rotary selectors that demand deliberate operator intention.
“Friction is not an obstacle to action; it is the physical medium through which human intention is calibrated into mastery.”
