CORE DEFINITION

The massive amount of data generated by the Internet permeates life like smog, and due to lack of context, fragmentation, and difficulty in distinguishing truth from falsehood, it actually hinders our ability to see facts clearly and impairs thinking ability.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Cognitive air pollution. Don't think that reading more news means caring about the world. Most instant news is Data Smog (toxic particulate matter). For health, you need to wear a 'cognitive mask': only read long articles and classic books, and block fragmented pushes.

anchor

Anchor fast decisions

David Shenk proposed that information overload obscures judgment like smog, and excessive low-quality information reduces rather than improves decision quality. It is analogous to air pollution.
