Leslie Jamison is the author of The Empathy Exams, The Recovering, and the novel The Gin Closet. Her new essay collection is Make It Scream, Make It Burn.

“My writing is always basically asking: what does it feel like to be alive, and how do we ever try to understand what it feels like for anybody else to be alive? In that sense, on the intellectual level, I’m always going to keep chasing the same unanswerable things.”

Joshua Yaffa is a Moscow correspondent for The New Yorker. His first book is Between Two Fires: Truth, Ambition, and Compromise in Putin's Russia.

“Especially in a place like Russia, where there’s a lot of sensitivity around what people might tell you—when they do open up to you, there’s a lot of trust there. And you better not abuse it or mishandle it, because you could put people in danger. Just being a decent person, and demonstrating that decency, goes a long way.”

Chris Hayes hosts All In with Chris Hayes on MSNBC and is an editor-at-large for The Nation.

"The instability was so intense and the anguish and frustration were so intense that there wasn’t a ton of time to think through, 'Well, what is my role in this?' Mostly it was: wake up in the morning after two or three hours of sleep and start going to stuff, talking to people, and keep doing that until the show happens."

Jon Ronson, a contributor to This American Life, The Guardian and GQ, is the author of six books, including The Men Who Stare at Goats. His latest is Lost at Sea: The Jon Ronson Mysteries.

"The older you get, you realize that no uncomfortable fact makes your story worse. Contradictions are great. What's bad, what to me is the worst journalistic sin, is ridiculous polemicism. ... To me, the contradictions, the story not turning out the way you want—you have to be a twig in the tidal wave of the story."

Azmat Khan is an investigative reporter and a contributing writer to The New York Times Magazine.

"For me, what matters most is systematic investigation, and I think that’s different than an investigative story that might explore one case. It’s about stepping back and understanding the big picture and getting to the heart of something. It doesn’t have to be a number’s game, but being able to say: Look, I looked at a wide enough sample of whatever this issue is, and here is what this tells us. That is what I crave and love the most."

Nick Bilton is a special correspondent for Vanity Fair and the author of American Kingpin: The Epic Hunt for the Criminal Mastermind Behind the Silk Road.

“I’ve been covering tech for a long, long time. And the thing I’ve always tried to do is cover the people of the tech culture, not the tech itself. … I've always been interested in the good and bad side of technology. A lot of times the problem in Silicon Valley is that people come up with a good idea that’s supposed to do a good thing—you know, to change the world and make it a better place. And it ends up inevitably having a recourse that they don’t imagine.”

Jon Mooallem is a contributing writer at the New York Times Magazine and author of an upcoming book on people and wild animals.

"If I just kind of assume it's going to work out one way or another, it can be a real fun adventure to find the path from here to there. You know, hopefully just as you do more, that excitement starts to outweigh the horror of messing up."

Sam Biddle writes for Valleywag.

"It's a lot of overgrown, entitled manchildren pulling price tags out of the ether and passing them around. Considering Silicon Valley worthy of contempt is the first premise that we work from."

Jiayang Fan is a staff writer for The New Yorker. Her latest article is a "How My Mother and I Became Chinese Propaganda."

"I think considering the unusual shape of our lives—the lives of my mother and I—from bare subsistence to one of the richest enclaves in America … it made me think about what the value of existence is. ... It made me wonder, What should a person be? And how should a person be? And being a writer has been a lifelong quest to answer those questions."

Rukmini Callimachi covers ISIS for The New York Times. Part 2 of this episode is available here.

“Nine out of 10 Americans said they were aware of James Foley's execution. That's a huge win for ISIS. That's what they want. I think they've realized that journalists are the crème de la crème as far as targets. And that's a really scary thing for our profession.”

Susan Casey is the former editor of O and the author of three New York Times bestselling books. Her latest is Voices in the Ocean: A Journey into the Wild and Haunting World of Dolphins.

“The funny thing is people often say, ‘You must be fearless.’ I’m always afraid of whatever it is. But for whatever reason—I think it’s partly naïvety, partly just overwhelming curiosity—I am also not going to let fear stop me from doing things even if I feel it. Unless it’s that pure…you do have to listen to your body sometimes if it tells you not to do something that could result in you really never coming up from falling on that 70-foot wave.”
