It is possible to study human behavior on great scale and in fine detail simultaneously. Online services and ubiquitous computational devices, such as smartphones and modern cars, record our everyday activity. The resulting Big Data offers unprecedented opportunities for tracking and analyzing behavior.

Psycho-Informatics is the application of Big Data to psychology and psychiatry. Highly sensitive, the suggested method collects, stores, and analyzes massive amounts of indicative data at little cost and without risks or stress for patients or participants. It collects data on a much finer granularity than conventional questionnaires and enables the search for temporal activity patterns.

Big Data will affect the daily routines of patients and clinical practitioners alike. The former will collect seemingly unrelated data to share with coaches and therapists. Provided with the necessary toolkits and expertise, the latter will be able to observe the course (and origins) of a disorder as well as the progress of treatment.

This will be more accurate compared to previous self-reports, and of such fine granularity as to allow a highly individualized medication.

Compared to traditional methods, this data-driven therapy will be cheaper, and consume less time from both, therapists as well as patients.
