Erroneous gambling-related beliefs emerge from broader beliefs during problem-solving: a critical review and classification scheme

Abstract Erroneous gambling-related beliefs (EGRBs) can be defined as beliefs that imply a failure to recognise how commercial gambling activities are designed to generate a guaranteed loss to players. In theorising about how EGRBs develop, previous reviews have proposed that EGRBs are extensions of decision-making heuristics and associated biases. We propose an alternative generative mechanism: one in which gambling games make substantial wins seem possible through problem-solving and eventual correct strategic action. EGRBs are then beliefs in the possibility of correct strategic action (illusions of control) that develop as players trial candidate strategies—strategies selected based on various broader beliefs. We further propose that EGRBs can be classified based on what is theorised in cognitive science about categories of general human beliefs about the world. For example, it has been theorised that human beliefs about supernatural forces and randomness have certain similarities across cultures, and so we propose that there exists a category of supernatural EGRBs, as well as a category of EGRBs based on broader beliefs about the nature of randomness. We review evidence for this classification scheme and discuss how it can be applied in researching and treating gambling disorder.
