The present research examined the influence of improved knowledge of odds and mathematical expectation on the gambling behavior of university students. A group of 198 Introductory Statistics students received instruction on probability theory using examples from gambling.One comparison group of 134 students received generic instruction on probability and a second group of 138 non-Statistics students received no mathematical instruction. Six months after the intervention, students receiving the intervention demonstrated superior ability to calculate gambling odds as well as resistance to gambling fallacies. Unexpectedly, this improved knowledge and skill was not associated with any decreases in actual gambling behavior. The implication of this research is that enhanced mathematical knowledge on its own may be insufficient to change gambling behavior.
Mathematics of gambling 3Does learning about the mathematics of gambling change gambling behavior?The current generation of youth are the first to have been raised in an environment of extensive legalized and government-sanctioned gambling. Perhaps as a consequence, several surveys have found the prevalence of gambling to be higher in young adults. The lifetime rate of gambling in North American college and university students typically ranges from 70% to 94% (Adebayo, 1998;Devlin & Peppard, 1996;Engwall, Hunter, & Steinberg, 2002;Kang & Hsu, 2001;Ladouceur, Dube, & Bujold, 1994;Lesieur et al., 1991;Oster & Knapp, 1998). A recent nationally representative study of college students in the United States (LaBrie et al., 2003) found a lower prevalence, but this study was limited by low response rates and not asking about all forms of gambling. The rates of problem and pathological gambling are also high among young people. National surveys in the United States (Gerstein et al., 1999), Australia (Productivity Commission, 1999), and Sweden (Volberg et al., 2001) have found the rate of problem and pathological gambling to peak in ages 18 to 24. Similarly, a meta-analysis of all North American prevalence studies found that the 19 study samples of college students appear to have higher overall lifetime rates of problem and pathological gambling (16.4%) than either adolescents (11.8%) or adults (6.1%) (Shaffer & Hall, 2001).Educational initiatives to prevent problem gambling have recently been undertaken.These efforts have largely been spearheaded by government agencies that provide treatment for substance abuse and problem gambling. Many of these agencies have developed ongoing 'awareness campaigns' consisting of 24 hour counselling hotlines; media promotion of responsible gambling; posters/pamphlets in gaming establishments letting people know about the signs of problem gambling and where to go for help; videos on problem gambling; etc. (e.g., AADAC, 2001;Murray, 2003;Jackson et al., 2002). Some jurisdictions (e.g., Australia, Canada,
