INTRODUCTION

English translation pending.

CORE DEFINITION

The well-traveled road effect is the finding that people systematically underestimate the distance and time of routes they travel often, and overestimate those they rarely take, even when the physical measurements are equal. The distortion comes from familiarity rather than from measurement: known routes are processed with less attention and remembered as fewer, smoother chunks. In decision making it means that comfort is routinely mistaken for efficiency, so the incumbent option looks cheaper than it really is.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Cost audit: ask whether the old option is genuinely cheaper or merely better known. - Novelty penalty: check whether a new approach is judged harshly only because it is unfamiliar. - Baseline test: ask how you would choose if you had never done either before.

Anchor fast decisions

Familiar processing is cheaper for the brain, so known routes are encoded as fewer and coarser chunks and feel brief. That reduced effort is then misread as reduced duration, which is why the same distance feels much longer the first time you travel it.
