Why do some surprises delight—the endings of Agatha Christie novels, films like The Sixth Sense, the flash awareness that Pip’s benefactor is not (and never was!) Miss Havisham? Writing at the intersection of cognitive science and narrative pleasure, Vera Tobin explains how our brains conspire with stories to produce those revelatory plots that define a “well-made surprise.”

By tracing the prevalence of surprise endings in both literary fiction and popular literature and showing how they exploit our mental limits, Tobin upends two common beliefs. The first is cognitive science’s tendency to consider biases a form of moral weakness and failure. The second is certain critics’ presumption that surprise endings are mere shallow gimmicks. The latter is simply not true, and the former tells at best half the story. Tobin shows that building a good plot twist is a complex art that reflects a sophisticated understanding of the human mind.

Reading classic, popular, and obscure literature alongside the latest research in cognitive science, Tobin argues that a good surprise works by taking advantage of our mental limits. Elements of Surprise describes how cognitive biases, mental shortcuts, and quirks of memory conspire with stories to produce wondrous illusions, and also provides a sophisticated how-to guide for writers. In Tobin’s hands, the interactions of plot and cognition reveal the interdependencies of surprise, sympathy, and sense-making. The result is a new appreciation of the pleasures of being had.

September 11, 2001, distinguished Cold War historian John Lewis Gaddis argues, was not the first time a surprise attack shattered American assumptions about national security and reshaped American grand strategy. We've been there before, and have responded each time by dramatically expanding our security responsibilities.

The pattern began in 1814, when the British attacked Washington, burning the White House and the Capitol. This early violation of homeland security gave rise to a strategy of unilateralism and preemption, best articulated by John Quincy Adams, aimed at maintaining strength beyond challenge throughout the North American continent. It remained in place for over a century. Only when the Japanese attacked Pearl Harbor in 1941 did the inadequacies of this strategy become evident: as a consequence, the administration of Franklin D. Roosevelt devised a new grand strategy of cooperation with allies on an intercontinental scale to defeat authoritarianism. That strategy defined the American approach throughout World War II and the Cold War.

The terrorist attacks of 9/11, Gaddis writes, made it clear that this strategy was now insufficient to ensure American security. The Bush administration has, therefore, devised a new grand strategy whose foundations lie in the nineteenth-century tradition of unilateralism, preemption, and hegemony, projected this time on a global scale. How successful it will be in the face of twenty-first-century challenges is the question that confronts us. This provocative book, informed by the experiences of the past but focused on the present and the future, is one of the first attempts by a major scholar of grand strategy and international relations to provide an answer.

When we are startled by the new, confronted with discrepancies, our knowing gives way to uncertainty—and changes. In the distinctive manner that has made him one of the most influential forces in developmental psychology, Jerome Kagan challenges scientific commonplaces about mental processes, pointing in particular to the significant but undervalued role of surprise and uncertainty in shaping behavior, emotion, and thought.

Drawing on research in both animal and human subjects, Kagan presents a strong case for making qualitative distinctions among four different types of mental representation—perceptual schemata, visceral schemata, sensorimotor structures, and semantic networks—and describes how each is susceptible to the experience of discrepancy and the feeling of surprise or uncertainty. The implications of these findings are far-reaching, challenging current ideas about the cognitive understandings of infants and revealing the bankruptcy of contemporary questionnaire-based personality theory. More broadly, Kagan’s daring, thoroughly informed, and keenly reasoned book demonstrates the risks of making generalizations about human behavior, in which culture, context, and past experience play such paramount and unpredictable roles.
