Social Science Theory

Artificial intelligence powers Google's search engine, enables Facebook to target advertising, and allows Alexa and Siri to do their jobs. AI is also behind self-driving cars, predictive policing, and autonomous weapons that can kill without human intervention. These and other AI applications raise complex ethical issues that are the subject of ongoing debate. This volume in the MIT Press Essential Knowledge series offers an accessible synthesis of these issues.

Its messaging can seem cryptic, even nonsensical, yet for tens of thousands of people, it explains everything: What is QAnon, where did it come from, and is the Capitol insurgency a sign of where it’s going next? Mike Rothschild, a journalist specializing in conspiracy theories, has been collecting their stories for years, and through interviews with QAnon converts, apostates, and victims, as well as psychologists, sociologists, and academics, he is uniquely equipped to explain the movement and its followers.

Tobacco is the quintessential American product. From Jamestown to the Marlboro Man, the plant occupied the heart of the nation's economy and expressed its enduring myths. But today smoking rates have declined and smokers are exiled from many public spaces. The story of tobacco's fortunes may seem straightforward: Science triumphed over our addictive habits and the cynical machinations of tobacco executives. Yet the reality is more complicated. Both the cigarette's popularity and its eventual decline reflect a parallel course of shifting political priorities.

What is "the big lie" of the Democratic Party? That conservatives - and President Donald Trump in particular - are fascists. Nazis, even. In a typical comment, MSNBC host Rachel Maddow says the Trump era is reminiscent of "what it was like when Hitler first became chancellor." But in fact, this audacious lie is a complete inversion of the truth. Yes, there is a fascist threat in America - but that threat is from the Left and the Democratic Party.

Groundbreaking scientific analysis that breaks the JFK assassination wide open! Did a shot from the "grassy knoll" kill President Kennedy? If so, was Oswald part of a conspiracy or an innocent patsy? Why have scientific experts who examined the evidence failed to put such questions to rest? In 2001, scientist Dr. Donald Byron Thomas published a peer-reviewed article that revived the debate over the finding by the House Select Committee on Assassinations that there had indeed been a shot from the grassy knoll, caught on a police dictabelt recording.

In this groundbreaking biography of the Japanese emperor Hirohito, Herbert P. Bix offers the first complete, unvarnished look at the enigmatic leader whose 63-year reign ushered Japan into the modern world. Never before has the full life of this controversial figure been revealed with such clarity and vividness.

Sam Tanenhaus's essay "Conservatism Is Dead" prompted intense discussion and debate when it was published in the New Republic in the first days of Barack Obama's presidency. Now Tanenhaus, a leading authority on modern politics, has expanded his argument into a sweeping history of the American conservative movement.

President Theodore Roosevelt forever transformed America, ushering the country into the arena of world supremacy. His brand of leadership was entirely American: confident, compassionate, energetic, diverse, visionary. But Roosevelt was not a born leader; his ascent to the apex of power was not a foregone conclusion.

Germany's financial collapse in the summer of 1931 was one of the biggest economic catastrophes of modern history. It led to a global panic, brought down the international monetary system, and turned a worldwide recession into a prolonged depression. Hitler managed to profit from the crisis, because he had been the most vocal critic of the reparation regime. As the financial system collapsed, his relentless attacks against foreign creditors and the alleged complicity of the German government resonated more than ever with the electorate.

Hannah Arendt's insightful observations of the modern world, based on a profound knowledge of the past, constitute an impassioned contribution to political philosophy. In Between Past and Future, Arendt describes the perplexing crises modern society faces as a result of the loss of meaning of the traditional key words of politics: justice, reason, responsibility, virtue, and glory. Through a series of eight exercises, she shows how we can redistill the vital essence of these concepts and use them to regain a frame of reference for the future.

Andrew Lambert, author of The Challenge - winner of the prestigious Anderson Medal - turns his attention to Athens, Carthage, Venice, the Dutch Republic, and Britain, examining how their identities as "seapowers" informed their actions and enabled them to achieve success disproportionate to their size. Lambert demonstrates how creating maritime identities made these states more dynamic, open, and inclusive than their lumbering continental rivals. Only when they forgot this aspect of their identity did these nations begin to decline.

Nomi Prins ushers us into the intimate world of exclusive clubs, vacation spots, and Ivy League universities that binds presidents and financiers. She unravels the multi-generational blood, intermarriage, and protégé relationships that have confined national influence to a privileged cluster of people. This unprecedented history of American power illuminates how financiers have retained their authoritative position through history, swaying presidents regardless of party affiliation.

The Idea of the World offers a grounded alternative to the frenzy of unrestrained abstractions and unexamined assumptions in philosophy and science today. This book examines what can be learned about the nature of reality based on conceptual parsimony, straightforward logic, and empirical evidence from fields as diverse as physics and neuroscience. It compiles an overarching case for idealism - the notion that reality is essentially mental - from 10 original articles the author has previously published in leading academic journals.

The struggle between individualism and the good of the community as a whole has been the basis of every major disagreement in our history, from the debates at the Constitutional Convention and in the run-up to the Civil War to the fights surrounding the agenda of the Progressives, the New Deal, the civil rights movement, and the Tea Party.

As America struggles with an economic debacle akin to the Great Depression, nothing could be timelier than an authoritative account of the New Deal, masterfully written by Michael Hiltzik, author of the acclaimed history of the Hoover Dam, Colossus.

In this richly peopled, vividly rendered narrative, Hiltzik describes how the urgent short-term relief measures of Franklin Roosevelt’s Hundred Days evolved into a transformative concept of the federal role in American life.

Howard Zinn’s A People’s History of the United States has sold over 2.5 million copies and is still required reading in some high school and college classrooms. But its polemic rewriting of American history as a story of oppression is an agenda-driven fairy tale that has no place in academia. In Debunking Howard Zinn, Mary Grabar debunks Howard Zinn’s lies and traces the damage his mega-bestseller has done to American education, culture, and politics.

On May 17, 1980, on the eve of Peru's presidential election, five masked men stormed a small town. They set election ballots ablaze and vanished, but not before planting a red hammer-and-sickle banner in the town square. The lone man arrested the next morning later swore allegiance to a group called Shining Path. Described by a US State Department cable as "cold-blooded and bestial", Shining Path orchestrated bombings, assassinations, and massacres across the cities, countryside, and jungles of Peru in a murderous campaign to seize power and impose a Communist government.

Our beliefs constitute a large part of our knowledge of the world. We have beliefs about objects, about culture, about the past, and about the future. We have beliefs about other people, and we believe that they have beliefs as well. We use beliefs to predict, to explain, to create, to console, to entertain. Some of our beliefs we call theories, and we are extraordinarily creative at constructing them. Theories of quantum mechanics, evolution, and relativity are examples.
