In "The Great Hack", what are the data points used in psychological profiling? I just saw the documentary "The Great Hack" (2019) about Cambridge Analytica. In it, they were talking about “data points” to profile people to better target them and persuade them into voting a certain way. I think they needed around 5000-6000 data points to achieve the claimed outcome.

Could anyone give an example of what a “data point” is in this case?
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.
