Special Report: The Poker Corner

Poker is, in many ways, a psychological laboratory of human behavior and a real-life metaphor for lie detection tactics. Even if you're unfamiliar with the game, I think you'll enjoy these six poker insights from my new book MINDREADER: The New Science of Deciphering What People Really Think, What They Really Want, and Who They Really Are.

The gambler's fallacy is the mistaken belief that if an event occurs more frequently than normal during a given period, it will occur less frequently in the future. In other words, random events are believed to be influenced by past occurrences. For example, if you flip a coin five times and it lands on heads each time, the erroneous belief is that tails are "due." However, since each flip is independent, the odds remain 50/50. In poker, this manifests when a player avoids bluffing after winning a large pot, assuming that their opponents won’t believe in their continued luck and are more likely to call a bluff.

A player who meticulously stacks their chips after placing a bet might be bluffing. By keeping the pot neat, they’re trying to avoid triggering their opponent’s calling reflex—the poker equivalent of road rage—where any perceived disrespect can cause impulsive, aggressive behavior. This neatness signals a desire to avoid confrontation, suggesting the player may be hiding a weak hand.

Amateur players often reveal themselves through two key behaviors. First, when they have a strong hand, they might perform an exaggerated display of disappointment—sighing, shrugging, or tsking—to project weakness. Second, when holding a weak hand, they’ll intensely study the flop (in Texas Hold ’em) as if searching for hope, whereas, with a strong hand, they’ll act disinterested and glance casually around the room to mask their excitement.

When a player bets heavily, it can be difficult to tell if they have strong cards or just courage. A bluffer often bets quickly to show confidence, while a player with a good hand may deliberately place their bets more slowly, feigning uncertainty. Professional poker players understand that bluffers try to appear strong, while those with strong hands may pretend to be weak.

Research has found that people subconsciously associate their dominant hand with positivity and their non-dominant hand with negative emotions. In poker, this translates into bluffers frequently using their non-dominant hand to place bets. While this isn’t a hard-and-fast rule, it serves as a reliable tell when combined with other indicators.

Nervous betting often signals a strong hand. The player feels the weight of the situation and the pressure to capitalize on it. Paradoxically, a bluffer tends to appear more relaxed because they’re in control—they can choose to bet, raise, or fold. The player with a strong hand, however, has no real choice but to stay in the game, which intensifies the pressure. As a result, bluffers often come across as more casual and confident than players with strong hands.
