Social Physics: How Social Networks Can Make Us Smarter

"From one of the world's leading data scientists, a landmark tour of the new science of idea flow, offering revolutionary ins into the mysteries of collective intelligence and social influence" If the Big Data revolution has a presiding genius, it is MIT's Alex "Sandy" Pentland. Over years of groundbreaking experiments, he has distilled remarkable discoveries significant enough to become the bedrock of a whole new scientific field: social physics. Humans have more in common with bees than we like to admit: We're social creatures first and foremost. Our most important habits of action--and most basic notions of common sense--are wired into us through our coordination in social groups. Social physics is about "idea flow," the way human social networks spread ideas and transform those ideas into behaviors. Thanks to the millions of digital bread crumbs people leave behind via s, GPS devices, and the Internet, the a of new information we have about human activity is truly profound. Until now, sociologists have depended on limited data sets and surveys that tell us how people "say" they think and behave, rather than what they actually "do." As a result, we've been stuck with the same stale social structures--classes, markets--and a focus on individual actors, data snaps, and steady states. Pentland shows that, in fact, humans respond much more powerfully to social incentives that involve rewarding others and strengthening the ties that bind than incentives that involve only their own economic self-interest. Pentland and his teams have found that they can study "patterns "of information exchange in a social network without any knowledge of the actual "content "of the information and predict with stunning accuracy how productive and effective that network is, whether it's a business or an entire city. We can maximize a group's collective intelligence to improve performance and use social incentives to create new organizations and guide them through
