Social Physics in Health
December 2014

Social PhysicsSociety enabled by Big-Data
Social physics deals with the question of how to create organizations that are more cooperative, productive, and creative?
The engine that drives social physics is the newly ubiquitous digital data that is becoming available about all aspects of human life.
By using these data to build a predictive, computational theory of human behavior we can hope to engineer better social systems.
Sensing (Datsets):
Call Data Records (CDRs)
Spending data (Credit and Debit cards)
Trading network (eToro)
Reality Mining (Living Labs)
Understanding (Predicting):
Decision making
Popularity vs. quality
Ties (e.g. trust relationships, reciprocity)
Team performance
Network dynamics
Emergencies
Shaping…
Sensing, Understanding and Shaping Social BehaviorSome examples…
The Friends and Family Living LabReality Mining
A revolution in social sciences
Longer duration
Higher measurement rate
Larger sample size
Richer data

OpenPDSThe new deal on data
Guiding principles:
You have the right to possess, control and dispose your data
Anonymization is hard
Share answers, instead of raw data
Open-source and Auditable

Sharing Social Health Data
Field trial application exploring the capacity for personal data to predict mental illnesses
Social health metrics calculated from fine-grained sensor data (calls, SMS, accelerometer, device state)
Collaboration with DARPA and Cogito
