I was thinking about this Alito filibuster over the weekend, and it struck me that the choice faced by politicians in this vote (and in almost every vote) is similar to the choice faced by the prisoner in the so-called "Prisoner's Dilemma." For those of you who are not familiar with game theory, the Prisoner's Dilemma is a deceptively simple game that illustrates the system of rewards and punishments for two players who must decide whether to cooperate or betray one another.
Entire books have been written on the Prisoner's Dilemma, so I'm not even going to try to do it justice. Wikipedia has a good primer, which is worth reading. The basic gist is this: Two people are caught by the police, and are interrogated separately. If these two prisoners cooperate with each other and refuse to talk, then they both serve six months. If one prisoner defects and rats out the other prisoner while the other prisoner stays silent, then the defector gets off scott free and the silent prisoner gets 10 years in prison. If both prisoners defect, then they both serve 10 years in prison.
The best outcome for both prisoners
together is to cooperate, in which case they will only serve a combined 1 year in prison. But the best outcome for a single prisoner is to defect when the other cooperates -- thus getting off scott free. If you think through all the options, you will see that the better choice for any
individual prisoner is to defect -- no matter what the other prisoner does, so there is a strong incentive to defect, and a strong disincentive to cooperate. In fact, it is not rational to *ever* cooperate. In order for mutual cooperation to take place, the two prisoners must 1) trust each other completely and 2) be willing to act altruistically toward the other prisoner (take a small personal penalty for the good of the group).
Which brings us to the Alito vote.
We can set up a prisoner's dilemma-style grid to show the rewards and penalties of cooperating (voting against Alito) versus defecting (voting for Alito). While I'm sure most Senator's weren't thinking of the prisoner's dilemma, I think it is fair to assume that they all think of votes in terms of rewards and penalties. In real life, the rewards and penalties for each senator would be different. (For example: A red-state Dem would likely perceive a greater penalty for cooperation than a blue-state Dem.) But here is the "generic" prisoner's dilemma grid for a Democrat deciding how to vote for Alito:
| Democrat "A" Cooperates | Democrat "A" Defects |
| (Votes against Extremist Judge) | (Votes for Extremist Judge) |
------------------------------------------------------------------------------------------------------
| WIN - WIN | "A" WINS MUCH - "B" LOSES MUCH |
Democrat "B" Cooperates | Democrats claim victory. | "A" joins high-profile victory. |
(Votes against | President humiliated. | "A" positions self as bipartisan |
Extremist Judge) | Extremist kept off SCOTUS. | and independent. |
| "A" and "B" possibly seen as | "B" publicly humiliated in |
| partisan and obstructionist. | high-profile defeat. |
------------------------------------------------------------------------------------------------------
| "B" WINS MUCH - "A" LOSES MUCH | LOSE - LOSE |
Democrat "B" Defects | "B" joins high-profile victory. | Extremist elevated to SCOTUS. |
(Votes for | "B" positions self as bipartisan | Fortunately there is not much |
Extremist Judge) | and independent. | media coverage of defeat |
| "A" publicly humiliated in | because there was unanimous |
| high-profile defeat. | vote and no public fight. |
------------------------------------------------------------------------------------------------------
Obviously, this purely hypothetical grid has been written with the Prisoner's Dilemma in mind, and does not represent the exact choice facing each Democrat (for one thing, it assumes that the Senate has only two Democrats: A and B). But I think it is instructive. No matter what happens, the "rational" choice for any
individual Democrat is to defect. But the best choice for all the Democrats
together is for everyone to cooperate. So the bottom line is that each Democrat is balancing their own personal fate against that of the party as a whole (and that of the nation).
I know that it is easy to stand in judgment and point fingers at politicians and say, "What a selfish bastard! He sold the rest of the party down the river to save his own ass!" And you would be right. But I would argue that it is unreasonable to expect politicians to not act like politicians. After all, that's why they call them "politicians." :)
So, how do we get out of this? Ultimately, the system of rewards and penalties must be changed so that Democrats believe it is not risky to cooperate, and it is risky to defect. (This is what we were doing when we made thousands of phone calls to their offices -- we were sending the message that they weren't going to get off so easily if they defect.) There must be a carrot and a stick. The rewards for cooperation must be greater, and the penalties for defecting must be greater. Sadly, much of this is outside of our ability to influence: the media punishes cooperation, and often a politician's own supporters and constituents will do so as well. The bottom line is that politicians are not going to stray far from what they feel the media and their donors and their constituents will allow. We must change the environment so that it is not so risky to stick one's neck out and support a progressive agenda.
It is my personal opinion that conservatives have succeeded in doing this. The risks of cooperation for a conservative politician are much lower than they were 25 years ago. Republicans have good reason to trust that if they cooperate, they won't get stabbed in the back by their fellow Republicans. Democrats... Not so much.
The bottom line is that politicians are rational beings. They weigh the options -- considering the rewards and penalties for themselves, for their party, and for their country -- and then they do the rational thing.
