A viral hypothetical widely shared online asks people to imagine a game in which everyone submits a private choice between pressing a “red” or “blue” button. The scenario states that if more than 50% of participants press the blue button, all players survive. If fewer than half press blue, only those who pressed red survive. The prompt is presented as a test of individual incentives under uncertainty and strategic thinking, commonly associated with classic game-theory problems such as coordination and equilibrium selection. One outlet uses the question to highlight how people evaluate moral and strategic risks when outcomes depend on what others do, noting the scenario’s appeal as a rapid, engaging thought experiment. Another outlet describes the rules of the hypothetical and frames it as an invitation to consider what players would do when they cannot observe others’ choices and must decide in isolation. Across sources, the emphasis stays on the structure of the game—private voting, a 50% threshold, and different survival outcomes—rather than reporting real-world events.
