Barry Nalebuff and Problems in Game Theory

Question: What are some problems with game theory?

Barry Nalebuff: It’s easy to create a strong man to attack game theory and if you literally think that the payoffs that you’ve written down are completely right, and that the other player and all the players are identical, you will come up with a really stupid answer that is misleading.  I think is a poor application of game theory.

That’s also why we called the book “The Art of Strategy.” There is a science behind it, but sometimes it uses a dialogue. It’s providing a common language so that we understand the reason why we think somebody is going to take the strategy is because they see all of these different options playing out on this way, do you agree with that?

Whereas our conclusion falls from our assumptions, so now we can understand do we have a common set of assumptions.

But this article points out something else that I think is even more important: that this multiple levels of game theory and I’d like to think of as [IB] META game theories, or it’s not just about solving a particular game, it’s about making sure you’re playing the right game.

So, how do you go back designing a game? And you can think about that, you could change the rules of the game. You can change the players in the game. You can change the payoffs in the game. You can link one game to another game. So you need to understand some game theory to figure out when I’m doing my game design. Are these changes likely to help me or likely to hurt me? And I think in the end I’m not going to be so precise to say it’s going to be 7.365% improvement, but it’s a good idea to link between negotiations or it isn’t a good idea to link between negotiations. And that’s the level at which I think we can be very helpful.

It’s not just about solving a particular game, it’s about making sure you’re playing the right game, according to Barry Nalebuff.

The big day has come: You are taking your road test to get your driver's license. As you start your mom's car with a stern-faced evaluator in the passenger seat, you know you'll need to be alert but not so excited that you make mistakes. Even if you are simultaneously sleep-deprived and full of nervous energy, you need your brain to moderate your level of arousal so that you do your best.

34 years ago, a KGB defector chillingly predicted modern America

A disturbing interview given by a KGB defector in 1984 describes America of today and outlines four stages of mass brainwashing used by the KGB.

Politics & Current Affairs
  • Bezmenov described this process as "a great brainwashing" which has four basic stages.
  • The first stage is called "demoralization" which takes from 15 to 20 years to achieve.
  • According to the former KGB agent, that is the minimum number of years it takes to re-educate one generation of students that is normally exposed to the ideology of its country.

How pharmaceutical companies game the patent system

When these companies compete, in the current system, the people lose.

Top Video Splash
  • When a company reaches the top of the ladder, they typically kick it away so that others cannot climb up on it. The aim? So that another company can't compete.
  • When this happens in the pharmaceutical world, certain companies stay at the top of the ladder, through broadly-protected patents, at the cost of everyday people benefitting from increased competition.
  • Since companies have worked out how to legally game the system, Amin argues we need to get rid of this "one size fits all" system, which treats product innovation — "tweaks" — the same as product invention.
