"This past year, I was a visiting scholar for the Phi Beta Kappa Society and went to small liberal arts colleges in the United States, and not only gave public lectures about science, but also research lectures, and then also spoke with women about the importance of bringing their intellectual force, which is formidable, to the scientific arena in the future."

And they said, suppose we know we're going to be paired together, I'll choose Beta if you choose Beta. Would that work?
他俩这么商量的,咱俩会被分到一组,你要是选β我也选β,这会成功吗
-
So I got into Pi Beta Phi which is fairly new here.
所以我进了Pi Beta Phi,一个挺新的联谊会。
-
Can I get the Beta in here? Who was the Beta in here?
这边有人选β的吗
-
The way I've written it, the beta of Shiller, Inc.
希勒公司.的beta值
-
The reason I chose Alpha, regardless of what my partner chose, I think there would be better outcomes than choosing Beta.
我选α是因为不管我对手选什么,我选α得到的成绩总会比选β的要好
-
Who would choose Beta? Very few Beta's, but mostly Alpha's. Alpha, I think, is the right answer here but why?
好,谁会选β,很少有选β的,基本都选的是α,α应该是正确答案
-
If my opponent chooses Beta and I choose Alpha, I get 3; Beta, I get 1. Once again Alpha is better.
如果我对手选β,我选α我得3,选β我得1,也是选α好
-
So if I did reason that way, and chose Beta, I'm not going to affect your choice one way or the other.
所以就算我这么推理了我选了β,但这些不会影响你的选择和你的推理
-
So I should choose Beta: 1 is bigger than 0, i should choose Beta.
因此我该选β,1比0大,我应该选β
-
So how can I get a mike into a Beta?
能不能把麦克风给一位选了β的同学
-
So certainly part of the problem here, with the reasoning I just gave you-- the reasoning that said I should choose Beta, because if we both reason the same way, we both do better that way-- involves some kind of magical reasoning.
那么说问题就出在了这里,就是之前我们说应该选β的问题,如果我们要都这么想,确实得到更好成绩,但这是有前提的
-
But if I choose Alpha and my pair chooses Beta, I get an A and she gets a C.
要是我选α我对手选β,我得A 她得C
-
And if I choose Beta and she chooses Alpha, then it's me who gets the C and it's her who gets the A.
如果我选β她选α,我得C而她得A
-
If you had chosen Beta we would have all gotten B+'s but I guess not.
如果大家都选β都能得B+,但不太可行
-
And if I put Beta and she puts Alpha, then she gets an A.
如果我选β她选α 那么她得A
-
If I put Alpha and she put a Beta, I got an A, and if I put Beta and she put an Alpha, I got a C.
如果我选α她选β 我得A,如果我选β她选α 那么我得C
-
If I choose Alpha and she chooses Alpha to get 0; Beta she gets -1. Alpha is better.
如果我选α,她选α她得0,选β她得-1,选α更好
-
It's still I'm choosing Alpha and Beta, my pair is choosing Alpha and Beta, and the grades are the same as they were before.
还是我选α和β,我对手选α和β,成绩的评判和之前是一模一样的
-
If I choose Beta, if she chooses Alpha she gets 3; Beta 1.
如果我选β,她选α得3,选β得1
-
It's as if I'm arguing that if I reason this way and reason myself to choosing Beta, somehow I'm going to make the rest of you reason the same way too.
这就好像是在说,要是我这么推理然后选了β,我有办法让你们也都用同样的方式推理
-
All right, so here once again is our same matrix with me and my pair, choosing actions Alpha and Beta, but this time I'm going to put numbers in here.
我们首先讨论我和我对手,选择α或β的矩阵,不过这次我们用数字来表述
-
And once I know that she's going to choose Alpha, it's clear that I should choose Alpha and get 0 rather than Beta and get -3. So I should choose Alpha also.
一旦我意识到她会选α的时候,很显然我应该也选α来得到0单位效用,而不是选β只得到-3,所以我也选α
-
What I'm gonna do is draw a larger table, the same basic structure: I'm choosing Alpha and Beta on the rows, my pair is choosing Alpha and Beta on the columns, but now I'm going to put both grades in.
我要画个结构相同的大表格,用列来表示我选α还是β,用行来表示我对手选α还是β,但我要把两人成绩写在一个单元格里
-
So I chose Beta.
所以我选了β
-
So what I'm going to do is I'm going to put me here, and my pair, the person I'm randomly paired with here, and Alpha and Beta, which are the choices I'm going to make here and on the columns Alpha and Beta, the choices my pair is making.
那么我把我写在这里,我对手,就是被随机分到的人写在这,还有是α和β,就是我要做的选择,还有我对手要做的选择
-
I mean if you chose Alpha, you're swinging from A to B-; and from Beta, swinging from B+ to C.
要是你选α,你的分数会在A到B-,选β,分数范围会在B+到C
-
Conversely, if I chose a Beta and my pair chooses an Alpha, so I end up with a C and she ends up with an A, then you know I have a bad time explaining to my parents why I got a C in this class, and I have to say about how I'm going to be president anyway.
相反如果我选β我对手选α,我得到C她得到了A,我回家后很难跟父母,解释为什么我只得到了C,然后我还得表示下雄心壮志
-
If my opponent chooses Alpha and I choose Alpha, I get 0; Beta, I get -1. So Alpha would be better.
如果我对手选α我选α,我得0,选β我得-1,选α更好
-
Even if I could make everyone in the room choose Beta by the force of my brain waves, What should I then do? I should choose Alpha.
就算我能用我脑波强迫,你们选β,那我应该选什么,我应该选α
