John's economics and morality

Dear Mr. Nash,

We know that Nash equilbrium is when, assuming you know the other person's strategy, changing yours won't make you better off. 

The gist of your idea is that we can't predict the choices of multiple people by analysing those decisions in isolation. We must instead ask what would each person do, taking into account the decision-making of the others. Well who can argue with your brilliance Mr. Nash.

However Mr. Nash, this works incredibly well with logic. Reality often neglects irrationality. Irrationality doesn't just involve the lack of thought, or ability to think but often springs from our emotions e.g. sadness, envy, anger..

In your movie "A Beautiful Mind", you explained to your friends that if they all went for the prettiest girl, they would all end up getting rejected. Instead of competing for the prettiest girl, strategising to approach someone different would promise everyone a companion at the end of the night. It's kinda hillarious seeing how a bunch of smart people agreed to that as you know, being scientists, their rationality supercedes their very much under developed emotions (or is this a discriminatory perception of smart people, haha). Therefore, your theory was agreeable, regardless of the fact that you ended up with the prettiest girl.

Let's steer this topic closer to the conclusion I am trying to make. There is a pervasive sentiment in almost every culture I know and one that is absolutely destructive is jealousy or to put it precisely "hasad dengki".
Sometimes the right decision will give someone else the best pay off but should that matter? Somehow some still prefer to make an irrationally bad decision just so that the other person won't gain at all. If only everyone on earth read economics (hah!), then everyone would understand why "hasad" or jealousy is stupid. right?

Sincerely,

A fan.
