Rosin was born in Israel and grew up in Queens, New York where her father was a taxi driver. She graduated from Stuyvesant High School in 1987. She graduated from Stanford University, and is married to ‘Slate’ editor David Plotz; they live in Washington, D.C. with their three children. She is a co-founder of ‘DoubleX,’ a women’s site connected to ‘Slate.’ She is also a writer for ‘The Atlantic.’ A character portrayed by actress Chloë Sevigny in the movie ‘Shattered Glass’ about Rosin’s colleague at ‘The New Republic,’ Stephen Glass, was loosely based on Rosin. Rosin has written a book based on her 2010 Atlantic story, ‘The End of Men.’
