Tie to the Boy, Lose the Man

CORE DEFINITION

The line xi xiaozi, shi zhangfu, tie to the boy and lose the man, comes from the Sui hexagram of the Yijing and describes holding on to something minor while letting the significant attachment slip away. The core proposition is that attention and resources are strictly limited, so every commitment to a low-value object is simultaneously a decision to forgo a higher-value one, even when no explicit choice was made. The key qualification is that the loss is invisible at the moment of choice, since the small gain is present and concrete while the forfeited alternative is only potential, which is why the error repeats so easily.
