INTRODUCTION

English translation pending.

CORE DEFINITION

From the Lu hexagram of the I Ching, which describes a person with one eye who can see, and a lame person who can walk, both proceeding despite insufficient capacity and needing caution against danger. The image identifies a specific failure mode: partial knowledge produces more confidence than complete ignorance, because it supplies enough competence to act without supplying enough to recognize the limits. The qualification is that the remedy is not abstention but caution and support. Its use is calibrating confidence to actual capacity.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Capacity audit: state explicitly what you can and cannot perceive about this situation. - Confidence calibration: check whether your certainty exceeds what your information supports. - Support sourcing: bring in the missing perspective rather than proceeding alone.

Anchor fast decisions

Complete ignorance produces caution, but partial knowledge produces a feeling of understanding, because the information available feels sufficient to form a judgment. The person therefore acts with confidence appropriate to full knowledge while holding only partial knowledge, and the gap between confidence and capacity is what converts a manageable situation into a damaging one.
