CORE DEFINITION

The ease with which the brain processes information. People tend to perceive information that is 'easy to read' as more true, credible, and beautiful. Using simple vocabulary, clear fonts, and short sentences can enhance the credibility of content. Scaffolding role: trust optimization. Do not try to appear smart by using complex vocabulary (which reduces fluency). The simpler you write, the more honest readers perceive you to be.

Anchor fast decisions

Processing ease is misused as a heuristic cue for 'true/beautiful/credible' (fluent is true). Fonts, sentence structure, and familiar words all affect fluency, which in turn affects judgment, constituting a metacognitive illusion.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

First, use simple vocabulary and short sentences in writing to enhance fluency and perceived credibility. Second, be wary of trusting information too readily because it 'reads smoothly'. Third, deliberately slow down reading for important information to counteract the fluency illusion.
