INTRODUCTION

English translation pending.

CORE DEFINITION

A Chinese idiom whose original scene is a court where sable tails used to ornament official caps ran short and dog tails were substituted. It now describes any continuation, sequel, or addition markedly inferior to what it extends. The qualification is that the judgment concerns the pairing rather than the addition alone: a modest addition is no problem until it is attached to something excellent, where it drags down the perceived quality of the whole. Its practical use is as a warning about feature padding and diluted sequels.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Quality gap check: compare each added piece against the standard set by the original. - Padding filter: cut additions made only to appear complete rather than to improve the whole. - Precedent risk: ask whether a weak sequel damages the standing of the original work.

Anchor fast decisions

Quality is judged against a reference point, and once an audience holds a high standard, anything attached to it is compared against that standard rather than against alternatives. A weaker addition therefore transfers negative evaluation to the whole, because the contrast is immediate and the original cannot be separated from its continuation.

Sherlocking

Sherlocking refers to the phenomenon where a platform owner copies the features of a third-party developer's app and integrates them into the platform, thereby rendering the third-party app obsolete. The term originates from Apple's Sherlock search tool, which was introduced in Mac OS 8.5 and later incorporated features similar to those of third-party search utilities like Watson, leading to the coining of the term.

Beat Frequency

The term "beat note" or "beat frequency" originates from acoustics, referring to the interference of two sound waves with similar but different frequencies. The resulting interference signal has a frequency equal to the absolute difference between the two original frequencies, hence the name. This concept is also applied in optics and electronics, where combining two signals of different frequencies yields a new signal with a frequency equal to their difference. For example, consider two sine waves with equal amplitude, no phase difference, but slightly different frequencies.
