Rhyme as Reason Effect
We perceive rhyming statements as more accurate and truthful than non-rhyming ones.
The rhyme-as-reason effect (or Eaton–Rosen phenomenon) is a cognitive bias in which a saying or aphorism is judged as more accurate or truthful when it rhymes than when it does not. 'Woes unite foes' is rated as more insightful than 'woes unite enemies,' despite identical meaning. This effect contributes to the persuasive power of advertising slogans, legal catchphrases, and political mantras.
