From the New York Times:
Agree, disagree, read the book or not: “Lean In,” the title of Sheryl Sandberg’s manifesto on women’s empowerment, has quickly become one of those ubiquitous slogans. One might even say it has reached a tipping point, to borrow a phrase that also made the leap from the best-seller list into everyday conversation. “Lean in” is the idiom of the moment for headline writers, the Twitterati and New Yorker cartoonists. Inevitably it has moved beyond mere shorthand for the ideas mapped out in Ms. Sandberg’s book, which urges women to assertively pursue career ambitions, “combine niceness with insistence” and demand that their partners share equally in child care… The fungibility of the phrase has certainly fueled its spread. “It’s short, digestible, easily interpretable and easily mis-interpretable,” said David S. Meyer, a University of California, Irvine, sociology professor.
