From one of the world’s leading data scientists, a
landmark tour of the new science of idea flow, offering
revolutionary insights 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 actionand most
basic notions of common senseare 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 smartphones, GPS devices, and the Internet, the
amount 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 structuresclasses, marketsand a focus on
individual actors, data snapshots, 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 disruptive
change in a way that maximizes the good. At every level of
interaction, from small groups to large cities, social
networks can be tuned to increase exploration and engagement,
thus vastly improving idea flow.
