Hey there, it's Stephen Dubner.
Quick announcement before today's episode, we have just added a new podcast to the Freakonomics radio network.
It's called Sudhir breaks the Internet.
The host is Sudhir Venkatesh, a sociologist at Columbia University who spent the first couple decades of his career embedding himself with drug gangs and gun runners and sex workers.
You may remember Sudir from the first freakonomics book.

Sudir wrote an amazing book himself, called gang leader for a day.
That book caught the attention of a guy named Mark Zuckerberg, who was running a company called Facebook.
And that is how Sudhir Venkatesh, Ivy League sociologist, chronicler of the criminal underworld, suddenly found himself in Silicon Valley working at Facebook.
