In the history books it seems really fast, Hitler and then war and holocaust.

That's not how it was experienced in real time. It was Hitler and then kind of threats of various sorts

and celebrations that seemed a little kind of over the top and

distracting and books things are happening to books and

what happened was as people described it in real time they thought at first this is like an

increment that's not good but it's not going to end up

where it did and each increment was bigger and less horrifying that it would have been if it had happened all in a flash.

So the people who were there said it was like being in a field with the corn growing and growing and

growing and then it's over your head.

But you didn't notice it going over your head until it was.

I'm John Favreau.

Welcome to offline.

I'm John Favreau. I'm Max Fisher. And you just heard from this week's guest Harvard Law Professor,

world-renowned behavioral economist and fellow Obama alum Cass Sunstein.

Cass and I are old friends having first met on the Obama campaign in 2008.

I probably could have invited him on the show to talk about any one of his books.

He's written over a dozen including the 2008 global

bestseller nudge but today I wanted to talk about his newest book look again

which is out on February 27th look again is a book about habituation, how when things become part of our

daily lives they begin to blend into the background, preventing us from fully appreciating

them or, in the worst case, understanding how they might harm us. It's a very offline book.

It sounds really good. It's very offline.
