That's not a very good reason

这可不是一个好的学习动机
and I certainly don't want you to jump to the conclusion

而且我可不想让大家觉得
that now we've got to Nash Equilibrium

我们花了这么多时间学纳什均衡
everything we've done up to now is in some sense irrelevant.

学到的却都是脱离实际的知识
That's not the case.

绝对不是这样的
It's not always going to be the case that people always play a Nash Equilibrium.

实际上并非所有情况都能达成纳什均衡
For example, when we played the numbers game,

比如说在我们之前玩的数字游戏中
the game when you chose a number,

每个人都选择一个数字
we've already discussed last week or last time,

我们之前讲解过的
that the equilibrium in that game is for everyone to choose one,

这个游戏的均衡就是每个参与人都选1
but when we actually played the game,

但实际操作下来
the average was much higher than that: the average was about 13.

平均数远高于1 在13左右
