I'll Have What She's Having

Humans are, first and foremost, social creatures. And this, according to the authors of the book, shapes-and explains-most of our choices. Our decisions are based on more than "nudges" exploiting individual cognitive quirks. The book shows us how we use the brains of others to think for us and as storage space for knowledge about the world. The story zooms out from the individual to small groups to the complexities of populations. It describes, among other things, how buzzwords propagate and how ideas spread; how focused social learning by a few gets amplified as copying by the masses.It describes how ideas, behavior, and culture spread through the simple means of doing what others do.
