Origin
The rhyme-as-reason effect was studied by researchers Matthew S. McGlone and Jessica Tofighbakhsh in their 2000 paper "Birds of a Feather Flock Conjointly(?): Rhyme as Reason in Aphorisms". Importantly, the term "Eaton-Rosen phenomenon" appears to be incorrect—it originated from an uncited 2013 Wikipedia edit and no researchers by those names published on this topic. McGlone and Tofighbakhsh demonstrated that rhyming aphorisms are perceived as more accurate than non-rhyming equivalents, establishing the cognitive basis for this persuasive effect.
