We know from chaos theory that even if you had a perfect model of the world, you'd need infinite precision in order to predict future events. With sociopolitical or economic phenomena, we don't have anything like that.
We have this culture of financialization. People think they need to make money with their savings rather with their own business. So you end up with dentists who are more traders than dentists. A dentist should drill teeth and use whatever he does in the stock market for entertainment.
We are victims of the post-Enlightenment view that the world functions like a sophisticated machine, to be understood like a textbook engineering problem and run by wonks. In other words, like a home appliance, not like the human body.
The Internet allows the small guy a global marketplace. But technology is harmful in the sense that we get too much information from it. Because of the web we get 10 times the amount of noise we ever got, which makes harmful fallacies far more likely.
People have the problem of denial. This is one of the things I learned in Lebanon. Everybody who left Beirut when the war started, including my parents, said, 'Oh, its temporary.' It lasted 17 years! People tend to underestimate the gravity of these situations. That's how they work.
Nature builds things that are antifragile. In the case of evolution, nature uses disorder to grow stronger. Occasional starvation or going to the gym also makes you stronger, because you subject your body to stressors and gain from them.
In social policy, when we provide a safety net, it should be designed to help people take more entrepreneurial risks, not to turn them into dependents. This doesn't mean that we should be callous to the underprivileged.
