Mark Zuckerberg Reveals His Next Book Club Choice

Facebook CEO picks book claiming violence has declined over time.

Zuckerberg called Steven Pinker's "The Better Angels of Our Nature: Why Violence Has Declined" a "timely book about how and why violence has steadily decreased throughout our history, and how we can continue this trend."

Since the book is 832 pages long, Zuckerberg said he'll take one month to read it but will keep with his resolution by naming another, shorter book in two weeks to complement the longer read.

The tech titan takes on an ambitious personal challenge every year. In previous years, he has tackled everything from learning Mandarin Chinese to writing thank you notes.
