If Then

Jill Lepore is the pre-eminent historian of forgotten tales from America’s past that throw startling light on the present. This brilliant book illuminates the future too. The story of the original data science hucksters of the 1960s is hilarious, scathing and sobering - what you might get if you crossed Mad Men with Theranos. It’s a reminder, in the age of Cambridge Analytica and whatever comes next, that we have been here before and should know better.

Jill Lepore is the David Woods Kemper ‘41 Professor of American History at Harvard University, where she teaches classes in evidence, historical methods, the humanities, and American political history. She is the author of The Name of War: King Philip’s War and the Origins of American Identity (winner of the Bancroft Prize), New York Burning: Liberty, Slavery and Conspiracy in Eighteenth-Century Manhattan (a finalist for the Pulitzer Prize), The Secret History of Wonder Woman (winner of the American History Book Prize), If Then (longlisted for the National Book Award) and many other titles. She is a staff writer at the New Yorker, host of the podcast The Last Archive, and was the winner of the Hannah Arendt Prize for Political Thought in 2021.
