Suffices to say you’ll understand multiple stats principles better after reading this book than after reading most stats book (I read many prior to reading this book), and that you’ll never think of your brain and ‘rationality’ on the same way again. Written by the only psychologist who ever won a Nobel prize in economics (not that I consider Nobel prices a meaningful thing!). He also writes a beautiful first chapter describing his amazing friendship Amos Tversky, and how their friendship guided them to find holes in the way they thought – and push to fill them.
