People judge a brand new game's fairness or fun by imagining just a few likely moves ahead.
Katherine M. Collins, Cedegao E. Zhang et al., People use fast and flat simulation to reason about new games, Nature.
People can guess how fun or fair a brand new board game will be, even before they play it once. More than 1,000 people tried 121 different two-player strategy games. Almost all of these games were new to them. They still played smartly from the very first try. They could also judge a game's fairness or fun level before making a single move. Scientists explain this skill with a new brain model. They call it the "Intuitive Gamer." This model imagines just a few likely next moves. It does not calculate every possible outcome, like a computer would. This quick, shallow kind of thinking seems to match how people naturally reason.
