Andrew Marantz writes narrative journalism about politics, the internet and the way we understand our world.

Andrew Marantz became a staff writer at the New Yorker in 2017. Prior to that, he worked on the magazine's editorial staff, splitting his time between writing stories (about such topics as hip-hop purism and the Truman Show delusion) and editing stories (about Las Vegas night clubs, Liberian warlords and many other things). Ultimately, Marantz's main interest lies not in any particular subject matter, but in how people form beliefs -- and under what circumstances those beliefs can change for the better.

Since 2016, Marantz has been at work on a book about the perils of virality, the myth of linear progress and the American far right. To report the book, he spent several years embedded with some of the conspiracists, white supremacists and nihilist trolls who have become experts at using social media to advance their corrosive agendas. He also watched as some of social media's earliest and most influential founders started to reckon with the forces they'd unleashed. The book, forthcoming in October from Viking Press, is called Antisocial: Online Extremists, Techno-Utopians, and the Hijacking of the American Conversation.

Marantz is also a contributor to Radiolab and The New Yorker Radio Hour, and has written for Harper's, Mother Jones, the New York Times and many other outlets. He holds an undergraduate degree in religion from Brown University and a master's degree in literary nonfiction from New York University. He lives in Brooklyn with his wife, who is a criminal-justice reformer; his two-year-old son, who is an excellent dancer; and an endless supply of peanut butter.

From a rising star at The New Yorker , a deeply immersive chronicle of how the optimistic entrepreneurs of Silicon Valley set out to create a free and democratic internet--and how the cynical propagandists of the alt-right exploited that freedom to propel the extreme into the mainstream.

For several years, Andrew Marantz, a New Yorker staff writer, has been embedded in two worlds. The first is the world of social-media entrepreneurs, who, acting out of na�vete and reckless ambition, upended all traditional means of receiving and transmitting information. The second is the world of the people he calls "the gate crashers"--the conspiracists, white supremacists, and nihilist trolls who have become experts at using social media to advance their corrosive agenda. Antisocial ranges broadly--from the first mass-printed books to the trending hashtags of the present; from secret gatherings of neo-Fascists to the White House press briefing room--and traces how the unthinkable becomes thinkable, and then how it becomes reality. Combining the keen narrative detail of Bill Buford's Among the Thugs and the sweep of George Packer's The Unwinding, Antisocial reveals how the boundaries between technology, media, and politics have been erased, resulting in a deeply broken informational landscape--the landscape in which we all now live. Marantz shows how alienated young people are led down the rabbit hole of online radicalization, and how fringe ideas spread--from anonymous corners of social media to cable TV to the President's Twitter feed. Marantz also sits with the creators of social media as they start to reckon with the forces they've unleashed. Will they be able to solve the communication crisis they helped bring about, or are their interventions too little too late?
