Sportwetten Expertise oder Glück? Ein systematischer Review über Tippstudien

One essential element of gambling refers to its outcome that is mainly or completely based on chance. This systematic review focuses on the question of whether sports betting should be classified as a game of chance or alternatively as a game of skill, in which certain competencies of the players play a decisive role in predicting sporting events. A systematic literature search revealed a total of 9 betting studies meeting our inclusion criteria, where different groups of persons bet on the outcomes of real sporting events, either against each other or against chance. Nearly all studies show that knowledge or other skills do not play a significant role in sports betting. This fact applies regardless of the type of sport, the specific sporting event or certain study parameters. Accordingly, sports betting should belong to the category of gambling in both a legal and political sense, and the corresponding measures from the gambling field for player protection and the protection of youth should be implemented. A central aim here is to prevent the development of cognitive biases such as the illusion of control, or the misconception that one's own expertise may help to make money in sports betting.
