Cognitive Factors that Predict Gambling Fallacy Endorsement.

Gambling fallacies are a collection of error-stricken beliefs about gambling and how gambling works. Gambling fallacies, while common in the general public, appear to increase as a function of gambling severity. This being the case, many interventions have focused on reducing gambling fallacies as a means of treating problem-gambling. Less research, however, has investigated what factors contributes to gambling fallacy susceptibility in the first place. Available studies have identified associations between gambling fallacy susceptibility and isolated individual differences in, for example, statistical reasoning/understanding, intelligence, or cognitive ability. The current study aimed to assess these cognitive factors in conjunction, and their relative predictive potential for gambling fallacy susceptibility. In an Australian university student sample (n = 90) it was found that there were moderate to strong association between gambling fallacy endorsement and general intelligence, probabilistic reasoning ability, rational cognitive style and the ability to suppress intuitive thought, however, only probabilistic reasoning, rational cognitive style and the ability to suppress intuitive thinking contributed to the prediction of fallacy endorsement. Importantly, each of these factors are malleable. Interventions for the correction of gambling-specific fallacious beliefs should focus on these factors.
