The Grue Divide: When Cognitive Accuracy Doesn’t Predict Affective Alignment

Kai Park


Abstract
This study presents a large-scale, exploratory investigation (9,534 trials from 1,159 participants) of color perception, cognition, and emotion in the Korean "Grue" spectrum, finding results consistent with a cognitive advantage for Korean speakers over English-speaking cohorts, particularly in Grue transitions. One illustrative case—the "Australia Divergence"—shows comparable cognitive accuracy between Korean and Australian cohorts in a preliminary, small-sample comparison (132 trials) that nonetheless appears to diverge affectively under the Sentiment-Formality-Friendliness (SFF) framework, consistent with a cognitive-affective decoupling in which perceptual precision may be shared across cultures while affective mapping remains culturally distinct. As a correlational, hypothesis-generating study, we offer these findings as a basis for future confirmatory research rather than as definitive claims, positioning SFF as a promising exploratory tool for capturing culturally mediated "emotional fingerprints" that traditional cognitive metrics may miss, though further validation against human ratings remains needed.
