Just saw the documentary about Cambridge Analytica where they we’re talking about “data points” to profile people to better target them and persuaded them into voting a certain way. I think they needed around 5000-6000 data points to achieve an outcome. Could anyone give an example of what a “data point” is in this case?

  • $\begingroup$ Welcome to Psychology.SE. Can you cite the documentary you are talking about? $\endgroup$ – Chris Rogers Jul 25 at 17:45

The 'data points' were collected by Cambridge Analytica through an app developed by Dr Aleksandr Kogan. The app was a personality quiz called This is Your Digital Life and was run on Facebook. It collected all kinds of data, including 'likes', birthdays and locations. So it was those kind of data points where Cambridge Analytica was bragging about. It claimed that it had up to 5000 data points on every US voter.

  • $\begingroup$ A data point is a number. As I say in the answer, a birthday, number of likes etc. $\endgroup$ – AliceD Jul 27 at 15:38
