cognitive fluency

You mistake easy thinking for the truth.

Cognitive fluency is the phenomenon where you evaluate information as more truthful if it is easy to process.

Information that is presented in a clear font, rhythmically spoken, or simply repeated feels more accurate to the brain than complex data. Your mind uses the 'effort' required for processing as a shortcut for validity. If it feels simple to understand, you assume it must be reliable.

You are judging the truth of the message by its polish.
