Overview of Rationality

In "Rationality," Steven Pinker tackles our mind's biggest paradox: why humans capable of logic remain stubbornly irrational. Praised by Columbia's Andrew Gelman for its accessible approach to Bayesian reasoning, this 2021 bestseller reveals why rationality isn't just academic - it's our civilization's most crucial survival skill.

The Rationality Paradox: Why Critical Thinking Matters Now More Than Ever

In an era of unprecedented scientific achievement - where we've dated the universe's origin, decoded life's secrets, and developed COVID vaccines in record time - our public discourse paradoxically drowns in conspiracy theories and "post-truth" rhetoric. Why does irrationality flourish when we have more knowledge than ever? This paradox sits at the heart of "Rationality," which arrives as both diagnosis and potential cure for our epistemic crisis. While we've used reason to extend human lifespans from thirty to over seventy years and reduce extreme poverty from ninety to less than nine percent of humanity, we still struggle with simple reasoning problems. Consider the bat and ball puzzle: "A bat and ball cost $110 total. The bat costs $100 more than the ball. How much does the ball cost?" If you immediately thought $10, you're wrong - that would make the total $120. The correct answer is $5. Such cognitive illusions don't indicate broken reasoning but reveal how our minds prioritize socially useful interpretations over mathematical precision - much like visual illusions show how our visual system optimizes for real-world accuracy rather than technical precision.
