Incongruously, before his book, "You're Too Kind: A Brief History of Flattery," was published, Stengel was senior adviser and chief speechwriter for one of the least flattering presidential candidates in recent history, the more-than-occasionally dour, former New Jersey Sen. Bill Bradley.

We caught up with Stengel -- at his new office at Time.com, where he was named managing editor last week -- to explore this angle.

So did Bill Bradley do enough flattering?

Well, first of all he subscribes to the sports ethos. And the coach's ethos. So when you say something is "pretty good," that means it's really fantastic. So, for example, if he said a speech I wrote was "pretty good," that in anyone else's vocabulary was "fantastic." And for me, as an ex-jock [like Bradley, Stengel played basketball at Princeton], I completely get that. It's a traditionally masculine thing. So that's on a staffer level.

What about to the American people? Did he flatter the voters enough?

Generally, Bill doesn't subscribe to the normal grade inflation of praise in our society. In the book I write that the ancient Greeks thought that the greatest worm in democracy was demagoguery -- but by that they meant politicians who flatter the public, flatter the demos. They saw that as a great danger.

Now we see that in modern days. Ronald Reagan was the greatest flatterer of the demos in our time. "I trust the wisdom of the American people," he would say. With Bill Clinton, it's the same deal. On the day he got impeached, he stood on the South Lawn of the White House and said that "the American people almost always get it right, they've been getting right for almost 200 years." Clinton is a master flatterer. He's always listening intently to us, telling us how great we are.

Bill Bradley, on the other hand, was a straight talker. While I believe he has a deep and abiding sense of the goodness of the American people ... he certainly didn't go overboard. He was almost closer to the Lincoln model -- you know, you can fool most of the public most of the time. Bill says "I see goodness in most of us" -- that's not flattery. He hedged the bet. It's certainly not flattery. It's a more stringent view. At the same time, he has an abiding faith in the mission of America. But he didn't deceive voters by telling us that we're the greatest thing since sliced bread.

And he didn't win.

One of things I realized during the campaign is that truth-tellers don't win. It's an archetype. And it's an archetype that we as voters like, though it waxes and wanes in popularity depending on what society is going through at the time.

You have to be something of a demagogue to really win. And demagoguery kind of goes against the grain with [Bradley]. There's a deep strain in him of this kind of Midwestern reticence. Reticence is the opposite of flattery in many ways. Well, there are two different opposites of flattery, there's reticence and there's what the Greeks called parhesia, which is candor. Or straight talk. The "Straight Talk Express" would be the "Parhesia Express" in ancient Greece.

But straight talk only takes you so far. [Arizona Sen. John] McCain was a straight talker with a smile. Bill was a straight talker who was a little more Calvinistic.

One of the biggest contrasts I saw during the campaign was that McCain constantly flattered us reporters, almost shamelessly, while Bradley avoided us like we were carriers of Ebola. And, whether or not it should have, that obviously worked for McCain and worked against Bradley.

McCain flattered reporters with his attention. What is more flattering to a journalist than someone who spends every frigging waking hour with you? Instead of spending time with his advisers, he's sitting around jawboning with Jake Tapper. One thing about flattery is it's free. There are no ad buys for flattery. No costs.

So McCain did it to the press corps. And the reaction of the press corps was "He likes us! He really likes us!" And they flattered him in return. One thing I discovered while writing this book was that at a very, very primal basis we like people who like us. If you're flattered by someone, you flatter him back. So that's what McCain did.

Bill ... he doesn't flatter journalists. He doesn't do the "I love your stuff" thing. I can't imagine that ever coming out of Bill's mouth. He treats it much more like a business relationship.

One of things I discuss in the book is how we flatter people by confiding in them. And that was also what McCain was doing. Reporters thought, "Oh, he trusts me." And that's why he got protected. Bill has a much more skeptical view of the press. I think it comes out of his experience as an athlete -- particularly when he was a young athlete -- so it's a much more neutral relationship.
