"From the wiki about Cambridge Analitica:
CA's data analysis methods were to a large degree based on the academic work of Michal Kosinski. In 2008, Kosinski had joined the Psychometrics Centre of
Cambridge University where he then developed with his colleagues a profiling system using general online data, Facebook-likes, and
smartphone data.
[45][46] He showed that with a limited number of "likes", people can be analysed better than friends or relatives can do and that individual psychological targeting is a powerful tool to influence people.
[45]CA would collect data on voters using sources such as
demographics,
consumer behaviour,
internet activity, and other public and private sources. According to
The Guardian, CA used psychological data derived from millions of Facebook users, largely without users' permission or knowledge.
[47] Another source of information was the "Cruz Crew"
mobile app that tracked physical movements and contacts and according to the
Associated Press, invaded personal data more than previous presidential campaign apps.

Quote :Today in the United States we have somewhere close to four or five thousand data points on every individual ... So we model the personality of every adult across the United States, some 230 million people.
