As a supplement to the newest Freakonomics book called "Super Freakonomics", the Freakonomics Podcast on the New York Times website features updated elements from both Freakonomics books and their brand of economic theory applied to brand new societal subjects you've experienced but probably not thought much about.
The newest episode titled "Faking It" focuses on faking it in social situations, politically and religiously.
Its worth a listen.
