Abstract

In the domain of scratch card gambling, "pushes" refer to outcomes in which a prize is won that is equal to the cost of a scratch card game. Despite resulting in no net monetary gain, these outcomes are categorized as wins by lottery operators, effectively inflating published scratch card information (e.g., posted odds of winning). Additionally, the experience of obtaining a push shares similarities (e.g., the revealing of matching symbols) with the experience of obtaining a win and thus may be experienced similarly to wins by gamblers. Across four studies (N = 1502), we examined the impact of push outcomes on participants' perceptions of scratch card games. In Studies 1 and 2, participants reported feeling more likely to win, more excitement to play, and a stronger urge to gamble when presented with a scratch card that categorized push outcomes as wins compared to when presented a scratch card that did not categorize these outcomes as wins. In Study 3, participants experiencing a push outcome prior to a loss reported feeling more likely to win compared to those not experiencing a push outcome yet experiencing the same net monetary loss. In Study 4, push outcomes were found to elicit more excitement and a stronger urge to gamble compared to losses but less excitement and a weaker urge to gamble compared to wins. Overall, the present investigation suggests that push outcomes, a prevalent feature of scratch card games, can bias gambling-related judgments and increase the appeal of scratch card games.
