4.0

A great overview about data, probabilistic predictions, forecasts, uncertainty, and noise.
One of those books most people should have read. I think it was the right mix of in depth and breadth analysis, although I was still sometimes a little bored, either because I already knew the concepts from school, or because I am really not that interested in Baseball and Poker.

After this read, I want to question my assumptions on this world more and try to stop and think about probabilities a little more often.

I also really recommend reading the 2020 preface twice. Once in the beginning and then again at the end with all the new knowledge.
