There are heuristics that could help us make fewer mistakes, and we have not been followed them much in the last few decades.
- when it comes to food, innovation is usually bad and research is often wrong; instead it is safer to assume that the way people have been eating something for hundreds or thousands of years is likely evolved to be optimal; treat all proposed changes very conservatively.
- when it comes to government, less is more, as long as the rules are in place to protect the weak. So healthcare for example shouldn't be designed to save money to the middle class but to make sure those who can't afford essential treatment nevertheless receive it.
