rhyme as reason

Your brain prefers information that sounds like music.

Statements that rhyme are judged as more accurate than the same statements written without rhymes.

In a 2000 study, participants consistently rated aphorisms like 'woes unite foes' as more truthful than 'woes unite enemies.' The brain processes rhymes with higher fluency, and people mistakenly attribute this ease of processing to the statement’s factual correctness.

Your mind uses ease of thought as a proxy for truth.
