The casino's practice of displaying the latest spins of the roulette wheel serves a psychological purpose rather than a practical one. By providing this information, they enable gamblers to create a false sense of control over their chances, as it leads them to believe they can predict future outcomes based on past results. This clever tactic plays into the human tendency to find patterns in random events, ultimately benefiting the house.

In essence, the observation highlights how casinos manipulate information to influence gambler behavior. It underscores the broader theme of the book, which discusses how perceptions of risk and chance can be distorted, leading individuals to make decisions based on misguided assumptions, especially in high-stakes environments like financial markets and gambling.
