The Book of Why: The New Science of Cause and Effect

The hugely influential book on how the understanding of causality revolutionized science and the world, by the pioneer of artificial intelligence

"Wonderful ... illuminating and fun to read" — Daniel Kahneman, Nobel Prize-winner and author of Thinking, Fast and Slow

"Correlation does not imply causation."

For decades, this mantra was invoked by scientists to avoid taking positions on whether one thing caused another — such as smoking and cancer, or carbon dioxide and global warming. But today, that taboo is dead.

The causal revolution, sparked by world-renowned computer scientist Judea Pearl and his colleagues, has cut through a century of confusion and placed cause and effect on a firm scientific basis.

What this book offers:

• A groundbreaking explanation of causal thinking: For the first time, Pearl and science journalist Dana Mackenzie bring causal thinking to general readers, showing how it allows us to explore the world as it is and imagine the worlds that could have been.
• The essence of human and artificial intelligence: Just as Pearl's discoveries have enabled machines to think better, The Book of Why explains how we, too, can think better.

"Pearl's accomplishments over the last 30 years have provided the theoretical basis for progress in artificial intelligence and have redefined the term 'thinking machine.'" — Vint Cerf
