Optimism bias

Gambling, in vegas is easier for rich people as the amount of money that they tend to risk as a percentage of their overall wealth is minimal. However, poorer people still gamble its just a lot harder for them.

A computer if you asked it to gamble all of its wealth on something that is risky would almost definitely say no. 100% of everything for 200% is not worth the risk of loosing everything. This means, with the numbers alone there is an optimism bias built into much of human reasoning. As early humans had to risk their lives every day.

Death is the ulltimate risk for humans. However, we need to do it, however if we thought about it too much we would not do anything. This is why medicine is so expensive in US and has to be socially administered in the majority of civilised countries. The greatest product you can see someone is the fear of death.

Optimism bias has to exists other wise nothing would be done.
