The Book of Why: Review

Just about everyone knows that correlation is not causation, but what exactly is causation? Judea Pearl has spent over two decades trying to u nderstand causation, to define it, and to develop techniques for inferring it. This work is having a great impact, and will arguably ultimately have as great an impact as Pearl's earlier work on Bayesian networks. Pearl's landmark book Causality was a technical introduction to his work on the topic. The Book of Why is meant to be a more popular introduction to the work, as well as documenting some of Pearl's personal journey throug h causation.
