Из того что интересно:
1. ... the claim that Facebook shut our app down and then I got it reactivated by telling them it was for academic research is a fabrication. If my memory is right, we hit the API rate limit, and once we paused collection for a minute, were able to continue. There was no exchange with Facebook about it, and, as I detail below, we never claimed during the project that it was for academic research. In fact, we did our absolute best not to have the project have any entanglements with the University.
2. We eventually provided SCL with 30 million people’s predicted personality scores (all of them Americans). The predictions themselves are actually not useful for micro-targeting. The correlational accuracy between predicted and actual scores was around r = 0.3 for all big five traits ... the predictions we gave SCL were 6 times more likely to get all 5 of a person’s personality traits wrong as it was to get them all correct. In short, even if the data was used by a campaign for micro-targeting, it could realistically only hurt their efforts. I’ve tried quite hard to explain this to reporters [но это, разумеется, никому было не интересно]
Даже не знаю что тут комментировать.
