Friction: any force that makes an action harder, slower, or less likely to occur, operating on a spectrum from micro-friction (one additional click, a slightly longer reach, a moment of hesitation) to macro-friction (filling out a form, driving across town, waiting in a queue)
Why This Is a Definition
This definition precisely establishes the semantic boundary of 'friction' within the behavioral science context, naming the term, stating its genus (force affecting action), and its differentia (making actions harder/slower/less likely). It distinguishes it from other concepts like cost or effort while providing clear examples across a spectrum.
