Trolling. Conspiracies. Social media pile-ons. Campus intolerance. On the surface, these recent additions to our daily vocabulary appear to have little in common. But together, they are driving an epistemic crisis: a multi-front challenge to America's ability to distinguish fact from fiction and elevate truth above falsehood.In 2016 Russian trolls and bots nearly drowned the truth in a flood of fake news and conspiracy theories, and Donald Trump and his troll armies continued to do the same. Social media companies struggled to keep up with a flood of falsehoods, and too often didn't even seem to try. Experts and some public officials began wondering if society was losing its grip on truth itself. Meanwhile, another new phenomenon appeared: "cancel culture." At the push of a button, those armed with a cellphone could gang up by the thousands on anyone who ran afoul of their sanctimony.In this pathbreaking book, Jonathan Rauch reaches back to the parallel eighteenth-century developments of liberal democracy and science to explain what he calls the "Constitution of Knowledge"--our social system for turning disagreement into truth.By explicating the Constitution of Knowledge and probing the war on reality, Rauch arms defenders of truth with a clearer understanding of what they must protect, why they must do--and how they can do it. His book is a sweeping and readable description of how every American can help defend objective truth and free inquiry from threats as far away as Russia and as close as the cellphone.

    They demonstrate that voters even those who are well informed and politically engaged mostly choose parties and candidates on the basis of social identities and partisan loyalties, not political issues. They also show that voters adjust their policy views and even their perceptions of basic matters of fact to match those loyalties. When parties are roughly evenly matched, elections often turn on irrelevant or misleading considerations such as economic spurts or downturns beyond the incumbents' control; the outcomes are essentially random. Thus, voters do not control the course of public policy, even indirectly.Achen and Bartels argue that democratic theory needs to be founded on identity groups and political parties, not on the preferences of individual voters. "Democracy for Realists" provides a powerful challenge to conventional thinking, pointing the way toward a fundamentally different understanding of the realities and potential of democratic government."

    This book will help you discover what it is, and how to win it back. Written by Mel Robbins, one of America’s top relationship experts and radio/tv personalities, this hands-on guide not only shows you how to put your finger on the problem, it reveals what to do about it.   Mel Robbins has spent her career teaching people how to push past their self-imposed limits to get what they truly desire.  She has an in-depth understanding of the psychological and social factors that repeatedly hold you back, and more important, a unique set of tools for getting you where you want to be.  In Stop Saying You’re Fine, she draws on the latest neuroscientific research, interviews with countless everyday people, and ideas she’s tested in her own life to show what works and what doesn’t.  The key, she explains, is understanding how your own brain works against you.  Because evolution has biased your mental gears against taking action, what you need are techniques to outsmart yourself.   That may sound impossible, but Mel has created a remarkably effective method to help you do just that -- and some of her discoveries will astonish you. By ignoring how you feel and seizing small moments of rich possibility –a process she calls “leaning in” – you can make tiny course directions add up to huge change.  Among this book’s other topics: how everything can depend on not hitting the “snooze” button; the science of connecting with other people, what children can teach us about getting things done; and why five seconds is the maximum time you should wait before acting on a great idea.   Blending warmth, humor and unflinching honesty with up-to-the-minute science and hard-earned wisdom, Stop Saying You’re Fine moves beyond the platitudes and easy fixes offered in many self-help books.  Mel’s insights will actually help vault you to a better life, ensuring that the next time someone asks how you’re doing, you can truthfully answer, “Absolutely great.”
