    The scarcity loop

    Can Las Vegas casinos teach us something about life in the modern age?

    In the 1970s, slot machines were seen as a boring novelty and rarely played. But today, slot machines are a multi-billion dollar industry, bringing in 30 billion dollars per year in the United States alone. They’re found in casinos, bars, restaurants, and even grocery stores. 

    What happened? How did slot machines evolve from a lackluster amusement to such a popular mainstay? 

    In the 1980s, an entrepreneur named Si Redd revolutionized slot design. Redd replaced the physical reels and mechanisms with digital machines and screens.  Moreover, he began redesigning the machines to take advantage of some quirks in the human brain – what the author calls the scarcity loop.

    The scarcity loop refers to a cycle of behavior that can compel people in a near-addictive manner. It has three key components – opportunity, unpredictable rewards, and quick repeatability.

    First, there needs to be an opportunity to obtain something valuable – something that could improve one’s life, like money or status. Second, the rewards offered must be delivered unpredictably, creating a sense of anticipation and suspense that pulls us in. Finally, there must be the ability to quickly repeat the behavior – this greatly strengthens the effect. 

    When all three elements are present, the scarcity loop creates an obsessive behavior cycle that’s tough to break. We keep chasing the opportunity for more unpredictable rewards by repeating the behavior again and again.

    To see how this works in practice, let’s look at how Redd – and the game engineers that followed him – transformed slot machines.

    The old mechanical slot machines only allowed betting on a single row of symbols per spin, so the odds of winning anything were slim. With such visibly poor odds, players quickly lost interest.

    With Redd’s new slot machines, players could bet on multiple lines per spin, creating both less predictability and potentially bigger rewards. Redd programmed rare but alluring jackpots that enticed players with the possibility of a huge windfall, or opportunity. Unpredictable rewards come from engineering frequent near misses and “losses disguised as wins.” Here, a player wins something – but they win back less than they originally wagered. For example, betting $1 and then winning 50 cents. Redd’s machines also added features like flashing lights, upbeat sounds, and exciting graphics to make playing more fun. This unpredictability of small wins and losses keeps people emotionally invested. Quick repeatability is built in by allowing rapid continuous play and instant spinning at the press of a button.

    Though a net loss occurred, these small wins, presented vividly, trigger the brain’s reward system in a way similar to how a genuinely significant win would. The excitement of seeming to win keeps players motivated despite the poor overall odds. Redd leveraged this psychological trick to entice continued gambling. 

    And game engineers today use math and psychology to further refine the art. By tapping into these powerful features of human behavior, Redd and his successors have turned slots into the massively popular and addictive experiences they are today.

    But of course, these innovations have hardly been contained to the casinos and slot machines. Today, scarcity psychology is embedded in many of our most addictive everyday technologies and activities. Social media notifications, online shopping, smartphone apps, video games – they all employ the same trio of opportunity, variable rewards, and speedy repetition. The algorithms of tech giants like Facebook learn exactly what content keeps us staring at screens, ceaselessly scrolling for that next enticing piece of information or entertainment.

    These experiences prey on our innate craving to maximize our opportunity, yet leave us unsatisfied, always wanting the next hit. They override our rationality and fuel obsessive repetition. Understanding how the scarcity loop works offers insight into how experiences become habit-forming and difficult to resist.
