Game Theory

“To understand the effect of a strategy, we must ask the counterfactual: what would have happened if we had made a different move?” (p. 282)

Cognition

“Our brains are not sophisticated calculators; they are causal-inference engines designed to find ‘why’ before ‘how’.” (p. 25)

Memory

“Data is the memory of past associations, but it cannot tell us about cause and effect unless we bring a model to it.” (p. 31)
