Their model is if you have a lucky event you have P(talent) chance of doubling your capital and if you hit an unlucky event your capital is halved. Any step in time where you neither experience luck or unluck you are left unchanged. It seems wrong on face for several reasons:
- You need to be "lucky" in order to ever increase your wealth, which makes the "finding" that luck is more important than talent completely obvious from the way the model was designed
- Capital only changes by multiplication and division, so the fact that this model "recreated" the power distribution we see in wealth in the world is obvious from the setup. It was designed to be a power distribution and couldn't be anything else
- Talent has no effect on your life during unlucky or neutral periods in their model. This obviously fails to conform to the real world.
tldr; they designed a power-distributed model where luck was clearly more important than talent, and "discovered" that it showed a power distribution where luck is more important than talent.
