CORE DEFINITION

Proposed by McCombs and Shaw. The media may not be able to tell people what to think, but they can tell people what to think about. By adjusting the frequency and prominence of coverage, the media tell the public which issues are important.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Information immunity: When you notice that the whole internet is discussing something, realize that this may be a "set" agenda. Reflect: What important things have I ignored because they lack popularity?

anchor

Anchor fast decisions

The media allocate "cognitive salience" through the frequency and prominence of coverage, and the public judges the importance of issues accordingly (priming effect); the media do not tell you what to think, but frame what you think about.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

First, be aware that "whole-internet buzz" may be a set agenda. Second, actively check for "important matters ignored due to lack of popularity." Third, remain critical of the source of salience and set your own issue priorities.
