“The behavioral techniques that are being employed by governments and private corporations do not appeal to our reason; they do not seek to persuade us consciously with information and argument. Rather, these techniques change behavior by appealing to our nonrational motivations, our emotional triggers and unconscious biases. If psychologists could possess a systematic understanding of these nonrational motivations they would have the power to influence the smallest aspects of our lives and the largest aspects of our societies.

Michael Lewis’s The Undoing Project seems destined to be the most popular celebration of this ongoing endeavor to understand and correct human behavior. It recounts the complex friendship and remarkable intellectual partnership of Daniel Kahneman and Amos Tversky, the psychologists whose work has provided the foundation for the new behavioral science. It was their findings that first suggested we might understand human irrationality in a systematic way. When our thinking errs, they claimed, it does so predictably. Kahneman tells us that thanks to the various counterintuitive findings—drawn from surveys—that he and Tversky made together, “we now understand the marvels as well as the flaws of intuitive thought.”

Kahneman presented their new model of the mind to the general reader in Thinking, Fast and Slow (2011), where he characterized the human mind as the interrelated operation of two systems of thought: System One, which is fast and automatic, including instincts, emotions, innate skills shared with animals, as well as learned associations and skills; and System Two, which is slow and deliberative and allows us to correct for the errors made by System One.”
