What is The Book of Why about?
The Book of Why (2018) explains the new science of cause and effect. Judea Pearl and Dana MacKenzie show why data alone cannot tell us why things happen, and introduce the ladder of causation, which moves from seeing patterns to testing interventions and imagining what would have happened otherwise. The book reveals how causal thinking is changing medicine, economics, and artificial intelligence.
Who should read The Book of Why?
- Data scientists who want to move beyond correlation
- Researchers in medicine or economics who test interventions
- Anyone curious how AI could understand causes
