INTRODUCTION

English translation pending.

CORE DEFINITION

Selective exposure describes the tendency to select, read and remember information consistent with one's existing beliefs while avoiding inconsistent information. The behavior reinforces prior positions and contributes to the formation of echo chambers, since the information environment is filtered by preference before it is filtered by argument. Because the filter operates ahead of any evaluation, the resulting confidence rests on a censored sample rather than on evidence.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Subscribe to the other side: deliberately read sources that argue against your current position. - Assign the search: make someone responsible for finding the strongest counterargument. - Check the diet: audit where your information actually comes from in a normal week.

Anchor fast decisions

Reading information that challenges a belief produces discomfort, while confirming information produces agreement and reassurance. Choosing what to read therefore favours comfort, and over time the available evidence appears overwhelmingly one-sided. Because the filtering happens before any evaluation, the confidence that results is not evidence-based.
