Revolutions are a good example.

Often, we take a singular example as a template, without looking at all the things that failed using the same principles.

For examples, revolutions. How many revolution failed the way they are run right now? How many lead to worse conditions?
For example, writing like Stephen King. How many writers did not publish novels by trying his methods? How many were worse off?

Basing a revolution on past revolutions is not using first principles
