Gambling involves betting something of value on an event that is primarily dependent on chance. This activity has existed in virtually every society since prerecorded history and is incorporated into many local customs and rites of passage. Despite its widespread acceptance, gambling is often associated with negative social and economic impacts. Specifically, it has been associated with increased crime, family dysfunction, poor health and mental illness, substance abuse, and suicide.

Gamblers may exhibit a variety of cognitive and motivational biases that distort the odds of events. These biases can lead them to make irrational decisions and overestimate the probability of a win or loss. In addition, gamblers are often influenced by their mood and a tendency to seek out excitement. These factors contribute to the high prevalence of problem gambling.

An estimated 2.5 million adults in the United States (1%) meet the diagnostic criteria for a gambling disorder. This figure is in addition to the 5-8 million who would be considered having mild or moderate gambling problems. The vast majority of those who gamble do so responsibly and are able to control their gambling habits.

Approximately 10% of gambling revenue is used to support programs for people with problem gambling. Despite this, the problem is growing and many states are struggling to adequately fund these programs. In addition, the stigma associated with seeking treatment for a gambling disorder makes it difficult for gamblers to admit they have a problem and seek help.

Studies have shown that some people are genetically predisposed to gambling problems. Research has also indicated that a person’s brain reward system can affect how they process risk information and regulate impulses. It is also possible that some individuals are more prone to gambling problems due to their culture or upbringing. Many cultures consider gambling to be a fun pastime, making it difficult for them to recognize when gambling has become a problem.

Problem gambling has a direct impact on the economy. Indirectly, it can create more jobs and generate more income in a community, while directly, it can cause more economic harm by increasing expenditures and taxes. The most effective way to examine these effects is through a “benefit-versus-cost” analysis, which attempts to identify the tangible and intangible benefits and costs of gambling. In addition to identifying the direct economic benefits and costs, these analyses should also consider real versus economic transfer costs, indirect effects, and expenditure substitution (Fahrenkopf & Meyer-Arendt, 1995). Unfortunately, these analytical methods are not always available in the field of gambling studies. This is an important gap that needs to be addressed. In addition, gambling-related benefits and costs should be measured across different regions to ensure a holistic view of the industry’s impacts. To this end, the development of new methodologies is crucial.
