Utilizing a Mixture-of-Thought (MoT) approach, we deploy six cognitive personas (e.g., The Absurdist, The Cynic) to synthesize diverse comedic perspectives for a given prompt.

These results suggest that cognitively driven data curation is more critical than alignment algorithms or model scale for humor generation."
