We examined knowledge about the role of randomness in gambling and the principle of independence of events, in a community sample. We also investigated whether this knowledge varies according to gender and age. A convenience sample of 1257 residents in French-speaking Switzerland, aged 18-88 years (28.5% of women) completed a short online questionnaire. This assessed the perceived role of human skills in four different games as well as beliefs relating to the principle of independence of events. The results show that 19.5% of the respondents perceived Roulette as a game for which the outcome is determined by skill. They also showed that 15.1% of the respondents did not hold beliefs about the independence of events principle. Gender and age differences were also observed: Men were proportionally more likely to hold erroneous beliefs about gambling skills and the independence of events, compared to women. The 18-25 year-old age group attributed Roulette outcomes to the gambler's skill more frequently than the older categories. The implications of these findings for prevention and social support are discussed.
我们在一个社区样本中研究了人们对赌博中随机性的作用和事件独立性原则的认识，还调查了这种知识是否因性别和年龄而异。在瑞士法语区，我们使用方便样本对 1257 名年龄在 18-88 岁的居民（其中 28.5%为女性）进行了一项简短的在线问卷调查。该问卷评估了人们对四种不同游戏中人的技能所起作用的看法，以及对事件独立性原则的信念。结果表明，19.5%的受访者认为轮盘赌的结果是由技能决定的。研究还表明，15.1%的受访者不相信事件独立性原则。我们还观察到了性别和年龄差异：与女性相比，男性更倾向于持有关于赌博技能和事件独立性的错误信念。与年龄较大的组别相比，18-25 岁年龄组更频繁地将轮盘赌的结果归因于赌徒的技能。我们讨论了这些发现对预防和社会支持的意义。
