Once you understand that, the world makes much more sense.
The world is a complex place, and we’ve figured out very little of it… Doctors have great expertise, but the unknowns of how our body works far outweigh the knowns. The best policy advisers around the world can only offer sincere, reasoned suggestions… but no one knows what will happen in, say, the Middle East or with global trade or global climate change.
We work with the best educated guesses we can… That’s as good as it gets.
