When we make decisions, our thinking is informed by societal norms, “guardrails” guiding our decisions, like the laws and rules that govern us. But what are good guardrails in today’s world of overwhelming information flows and increasingly powerful technologies, such as artificial intelligence? Based on the latest insights from the cognitive sciences, economics, and public policy, Guardrails offers a novel approach to shaping decisions by embracing human agency in its social context.

The world is a better place than it used to be. People are healthier, wealthier, and live longer. Yet the escapes from destitution by so many has left gaping inequalities between people and nations. In The Great Escape, Angus Deaton - one of the foremost experts on economic development and on poverty - tells the remarkable story of how, beginning 250 years ago, some parts of the world experienced sustained progress, opening up gaps and setting the stage for today's disproportionately unequal world.

The Arab Spring promised to end dictatorship and bring self-government to people across the Middle East. Yet everywhere except Tunisia it led to either renewed dictatorship, civil war, extremist terror, or all three. In The Arab Winter, Noah Feldman argues that the Arab Spring was nevertheless not an unmitigated failure, much less an inevitable one. Rather, it was a noble, tragic series of events in which, for the first time in recent Middle Eastern history, Arabic-speaking peoples took free, collective political action as they sought to achieve self-determination.

Marie Aymard was an illiterate widow who lived in the provincial town of Angoulême in southwestern France, a place where seemingly nothing ever happened. Yet, in 1764, she made her fleeting mark on the historical record through two documents: a power of attorney in connection with the property of her late husband, a carpenter on the island of Grenada, and a prenuptial contract for her daughter, signed by 83 people in Angoulême. Who was Marie Aymard? Who were all these people? And why were they together on a dark afternoon in December 1764?

Dark Data explores the many ways in which we can be blind to missing data and how that can lead us to conclusions and actions that are mistaken, dangerous, or even disastrous. Examining a wealth of real-life examples, from the Challenger shuttle explosion to complex financial frauds, Hand gives us a practical taxonomy of the types of dark data that exist and the situations in which they can arise, so that we can learn to recognize and control for them.
