手表定理是指一个人有一只表时,可以知道现在是几点钟,而当他同时拥有两只表时却无法确定。两只表并不能告诉一个人更准确的时间,反而会让看表的人失去对准确时间的信心。你要做的就是选择其中较信赖的一只,尽力校准它,并以此作为你的标准,听从它的指引行事。手表定理所指的另一层含义在于每个人都不能同时挑选两种不同的行为准 Watch theorem refers to a person has a watch, you can know what time it is, but when he has two tables at the same time but not sure. Two tables can not tell a person more accurate time, but will make the watch people lose the confidence of accurate time. All you have to do is choose the one you trust, try to calibrate it and use it as your standard, follow its guidelines. Another meaning of the watch theorem is that everyone can not pick two different behaviors simultaneously
