People may have biases when making decisions, which can affect their gambling behaviours. For example, they might rely on mental shortcuts to make quick decisions and over-estimate rare events (e.g., the chance of winning a jackpot). People with gambling problems often have faulty beliefs about gambling. For example, the illusion of control is a belief that one can control gambling outcomes. Gamblers’ Fallacy is the belief that past events can predict a future event even though they are random occurrences (e.g., a win is due to happen after a losing streak). These faulty beliefs can be encouraged by certain game features; for example, a stop button on a slot machine can cause people to believe that using it will change the outcome of the game.
