Critical Thinking examines how we make judgments under uncertainty and how various biases can distort our consideration of evidence. Via everyday examples, Varda Liberman and Amos Tversky explore the insights of probability, causal relationships, and making inferences from samples with the goal of helping readers improve their intuitive reasoning. This masterpiece is the fruit of long-term collaboration between Varda Liberman and Amos Tversky, the master of judgment and decision making. It is both a wonderful leisure read and a source of material for a fascinating undergraduate course. Readers will be inspired to think critically about their own reasoning. Some of them will likely report in a few years that this was the book that ushered them into the world of human reasoning and statistical inference.
