People use fast and flat simulation to reason about new games
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 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.
