🧠Researchers formalize 'affective meaning divergence' (AMD)—the divergence in emotional interpretation of shared words between conversation partners—and demonstrate that it undergoes a critical phase transition before conversational breakdown. Using game-theoretic modeling and empirical analysis of 652 conversations, they show that AMD exhibits critical-slowing-down signatures predictive of relationship rupture, outperforming toxicity and sentiment baselines.
