What does it mean to say that people like to ‘‘play with the house’s money’’?

Prospect theory, developed by Daniel Kahneman and Amos Tversky, is a behavioral economic theory that describes how people choose between probabilistic alternatives that involve risk, where the probabilities of outcomes are known. The theory posits that people make decisions based on the potential value of losses and gains rather than the final outcome, and that people evaluate these losses and gains using certain heuristics.

One of the key concepts of prospect theory is the 'value function', which is steeper for losses than gains, indicating that losses are felt more intensely than gains. This is known as loss aversion. In the context of gambling, this can lead to surprising behaviors. For instance, when a person wins money, they might feel emboldened to gamble with their winnings—the 'house's money'—as they perceive this money to be a gain from the casino. Prospect theory suggests that this perceived gain can result in riskier behavior because the individual is not as afraid of losing these earnings as they would be their own initial stake.

The psychological aspects of gambling are complex and can explain why individuals exhibit certain behaviors in a gambling setting. Gambling can be thrilling because it involves risk and the prospect of gaining money quickly. It taps into various psychological triggers such as the 'near-miss' phenomenon, where individuals feel they were close to winning, which can increase the temptation to try again.

The concept of 'playing with the house’s money' also illustrates a cognitive bias known as mental accounting. Gamblers categorize their winnings as separate from their own money, which leads them to treat it differently. Additionally, gamblers may experience an illusion of control, believing their skills or strategies have a direct impact on the outcome of a game of chance, further fueling their confidence to take more significant risks. The thrill of the potential reward often overshadows the rational assessment of the risks involved, leading people to gamble more than they can afford to lose.

Risk-taking is a fundamental element of gambling and can be influenced by various factors, including the psychological concept of 'chasing losses,' where individuals continue to gamble in an attempt to recover their losses. The illusion that one is due for a win can provoke taking higher risks, which is particularly true when playing with what is perceived as 'the house’s money'.

Individuals tend to be more willing to risk these winnings because they categorize them differently from their initial bankroll. This disconnection from the real value of money can result in gambling behaviors that would be untenable with their own hard-earned cash. The escalation of bets using winnings can quickly lead to the gambler losing not only the 'house money' but also their initial investment. Understanding the risk-taking behavior in gambling is critical for developing responsible gambling habits and can also lead to better strategies for managing gambling-related problems.
