Tonight on ABC’s “20/20”

Late notice, but: tonight I’ll be appearing on a two-hour John Stossel 20/20 special called “Scared Stiff: Worry in America” (9-11 p.m. EST). I loved the theme of the show when first approached and, when I started to think through what Freakonomics material would be worth talking about, I realized that nearly everything we’ve written about, either in the book or our journalism or the blog, has some element of people worrying too much about something (or, less frequently, not worrying enough). So sitting down to talk to Stossel about the subject was among the least harrowing TV experiences I’ve ever had. For all I know, I’ll end up all over the cutting-room floor but I’m looking forward to seeing the show regardless.
