Abstract
This review introduces the quantum Zeno effect in the context of belief updating, with a focus on cognitive biases related to delusions. It introduces two primary biases found in psychiatric disorders, particularly schizophrenia : the jumping to conclusions bias and the bias against disconfirmatory evidence (BADE) . While both biases are discussed, the review specifically emphasizes the relevance of BADE within the framework of quantum cognitive models. It provides an overview of these models, recent trends, and the theoretical underpinnings of the quantum Zeno effect, along with empirical studies. The review aims to deepen the understanding of how BADE contributes to the persistence of delusions and to propose future research directions in this area.
