INTRODUCTION

English translation pending.

CORE DEFINITION

The knowledge gap hypothesis holds that as mass media flood society with information, people of higher socioeconomic status acquire it faster than those of lower status, so the gap between them widens rather than shrinks. The reason is that information use depends on prior background knowledge and skill. The key condition is that the internet lowered the cost of access without lowering the cost of processing, so distribution alone cannot close the divide.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Processing focus: build real skill in critical reading and searching rather than piling up more information. - Background repair: supply the background context and tools that the disadvantaged lack. - Cocoon guard: watch algorithmic filter bubbles that keep widening the gap.

Anchor fast decisions

Information intake depends on the background knowledge and literacy a person already holds, so the better-educated absorb each new wave faster and the gap widens as information volume grows. Lowering access costs without lowering processing costs leaves the underlying inequality intact.
