Data given to Cambridge Analytica ‘highly inaccurate’

Aleksandr Kogan, who supplied the personal information of millions of Facebook users to election consultancy Cambridge Analytica (CA) in 2014, told British politicians that personality scores he gave to the company were “highly inaccurate” and “made little sense” for political advertising.
“The idea that this data is accurate, I would say, is scientifically ridiculous. The idea that even if you had a lot more data you could make it super accurate is also pretty silly,” he told a House of Commons select committee.
