When you play rock-paper-scissors, you might think your choices are completely random. However, groundbreaking research suggests there's more strategy involved than meets the eye, according to CTV's science and technology expert Dan Riskin.
The Science Behind the Game
In a recent segment that aired on November 18, 2025, Riskin discussed compelling evidence that challenges our understanding of this seemingly simple hand game. The study indicates that human players don't make truly random choices when selecting between rock, paper, or scissors.
While many Canadians view the game as a quick way to make decisions or settle disputes, the research reveals predictable patterns in how people play. These patterns could be influenced by various psychological factors, including previous moves, opponent behavior, and even unconscious biases.
What This Means for Game Theory
The findings have implications beyond casual playground games. Understanding the non-random nature of human decision-making in rock-paper-scissors could influence how researchers study game theory and behavioral psychology.
Dan Riskin, CTV's respected science communicator, highlighted how this research builds on previous studies about human pattern recognition and decision-making processes. The timing of this revelation comes as Canadians continue to embrace both traditional games and digital entertainment.
Broader Implications for Understanding Human Behavior
This research extends beyond the game itself, offering insights into how humans make quick decisions under pressure. The patterns observed in rock-paper-scissors choices might reflect broader cognitive processes that affect everything from consumer behavior to social interactions.
As Riskin explained during the November 18 broadcast, recognizing these patterns could help psychologists and researchers better understand human decision-making in various contexts. The study adds to growing evidence that what we perceive as random choice often follows predictable patterns once researchers identify the underlying factors.
The next time you find yourself in a game of rock-paper-scissors, remember that science suggests your opponent's moves might be more predictable than you think. This research continues to evolve as scientists explore the complex interplay between chance, strategy, and human psychology in even our simplest games.
