This book is a popularized text regarding Pearl's work on causal theory and do calculus. It is remarkable. The book tells the tale of how causal theory has been misunderstood for long in the science of statistics, mostly by the Anglo-Saxon null-hypothesis 'gang' of Fisher, Pearson and Galton; putting in doubt a lot of 20th century social research. The book also joyfully reveals how the commonly regarded 'simple' and 'explainable' linear model has been misapplied most of the times, putting my own doubts at rest.

Accounting started in around 5000 BC in Mesopotamia. It was not until the nineties that Edward Jaynes finalized the concept of Bayesian probability. Around this time Pearl also was making his work known. Statistics in the social sciences is just getting started.
