Wishful Thinking Revision

摘要

Wishful thinking is an affective bias towards more pleasant interpretations/beliefs. We model wishful thinking effects, to some extent, with a belief revision theory: Wishful Thinking Revision. By modeling tendencies to believe in goals, "disliked situations" appear as "contradicting beliefs" (the target of belief revision). Furthermore, the current set of beliefs is selected according to an assessment of preference that accounts for rational factors, as well as an affective factor: "likeability".
