Social closeness can help, harm and be irrelevant in solving pure coordination problems
通过比较社会亲近与疏远玩家在两人协调游戏中的表现，发现社会亲近对协调概率的影响取决于游戏结构，有时有益、有时有害、有时无影响。
Experimental research has shown that ordinary people often perform remarkably well in solving coordination games that involve no conflicts of interest. While most experiments in the past studied such coordination games among socially distant anonymous players, here we study behaviour in a set of two player coordination games and compare the outcomes depending on whether the players are socially close or socially distant. We find that social closeness influences prospects for coordination, but whether it helps, harms, or has no impact on coordination probabilities, depends on the structure of the game.
