Thanks to the rise of smartphones, GPS devices, and the internet, Pentland and his teams can study patterns of information exchange in a social network, without any knowledge of the content of the information. Using this data, they can tell with stunning accuracy how effective that network is, whether it’s a business or an entire city. Pentland shows us how to fine-tune these networks to improve their performance — for instance, by maximising a group’s collective intelligence, or by using social incentives to work through disruptive change.

Social Physics will change the way we think about how we learn and how our social groups work — and can be made to work better, at every level of society. It is an entirely new way to look at life itself.
