With the gambling market continuously shifting and evolving, one form of gambling has uninterruptedly remained a staple in most cultures. Sports wagering has been and remains one of the most popular forms of gambling, especially among males. With the increase in the gambling market, sports wagering has also grown into the online gambling and fantasy sports wagering markets. These escalations in popularity have brought substantial revenue to sports wagering operators and have influenced government officials, policymakers, legislation researchers, the media, and the general public. There are two major groups of issues that surround sports wagering: sports wagering as an economic and tax-generating entity and the integrity of the game. More recently, a concern over problem gambling from a public health perspective has evolved. It is equally important that these issues be considered when creating or changing legislation around sports wagering.

Scarcity is the condition of having insufficient resources to cope with demands. This condition presents significant challenges to the human cognitive system. For example, having limited financial resources requires the meticulous calculation of expenses with respect to a budget. Likewise, having limited time requires the stringent management of schedules with respect to a deadline. As such, scarcity consumes cognitive resources such as attention, working memory, and executive control and elicits a range of systematic and even counter-productive cognitive and behavioral responses as a result. Specifically, scarcity induces an attentional focus on the problem at hand, which facilitates performance by enhancing cognitive processing of information relevant to the problem, increasing the efficiency of resource use, and stabilizing the perception of value. Such prioritization of the problem at hand may seem advantageous, but it can produce undesirable consequences. For example, scarcity causes myopic and impulsive behavior, prioritizing short-term gains over long-term gains. Ironically, scarcity can also result in a failure to notice beneficial information in the environment that alleviates the condition of scarcity. More detrimentally, scarcity directly impairs cognitive function, which can lead to suboptimal decisions and choices that exacerbate the condition of scarcity. Thus, scarcity means not only a shortage of physical resources (e.g., money or time) but also a deficit of cognitive resources (e.g., attention, executive control). The cognitive deficits under scarcity are particularly problematic because they impair performance and lead to counter-productive behaviors that deepen the cycle of scarcity. In addition, people under financial scarcity suffer from stigmas and stereotypes associated with poverty. These social perceptions of poverty further burden the mind by consuming cognitive resources, weakening performance in the poor. Understanding the cognitive and behavioral responses to scarcity provides new insights into why the poor remain poor, identifying the psychological causes of scarcity, and illuminating potential interventions to stop the cycle of scarcity. These insights have important implications for the design and the implementation of policies and services targeting the populations under scarcity.

People’s behavior influences health, for example, in the prevention, early detection, and treatment of disease, the management of illness, and the optimization of healthcare professionals’ behaviors. Behaviors are part of a system of behaviors within and between people in that any one behavior is influenced by others. Methods for changing behavior may be aimed at individuals, organizations, communities, and/or populations and at changing different influences on behavior, e.g., motivation, capability, and the environment. A framework that encapsulates these influences is the Behavior Change Wheel, which links an understanding of behavior in its context with methods to change behavior. Within this framework, methods are conceptualized at three levels: policies that represent high-level societal and organizational decisions, interventions that are more direct methods to change behavior, and behavior change techniques that are the smallest components that on their own have the potential to change behavior. In order to provide intervention designers with a systematic method to select the policies, interventions, and/or techniques relevant for their context, a set of criteria can be used to help select intervention methods that are likely to be implemented and effective. One such set is the “APEASE” criteria: affordability, practicability, effectiveness, acceptability, safety, and equity.
