Cambridge Analytica and its partners used previously unknown data from "questionnaires connected to Facebook" to obtain data from users of the social network service, according to the testimony of a former employee of Cambridge Analytica.
Kaiser said that a "sexual compass" application was used to obtain data
Brittany Kaiser presented evidence to the British Parliament today as part of a hearing on false news. Kaiser, who worked on the business team at the parent company of Cambridge Analytica until January of this year, wrote in a statement that he was "aware in a general sense of a wide range of surveys" used by Cambridge Analytica or its partners, and She said the number of people whose Facebook data has been compromised is likely to be higher than the 87 million widely reported.
In the statement, she said that a "sexual compass" questionnaire was used to obtain data, and in the spoken testimony, she explained that the questionnaire was presented as a way to "discover what their personal preferences were in private." He also explained that he was also familiar with a questionnaire about "your musical personality".
"In my presentations, I used to give examples, even to clients, that if you go to Facebook and see these viral personality questionnaires, not all of them would have been designed by Cambridge Analytica, SCL Group or our affiliates, but these applications were specifically designed to collect data from people who use Facebook as a tool, "he said.
Cambridge Analytica obtained data on up to 87 million Facebook users through a personality test application designed by researcher Aleksandr Kogan. Facebook has said it has changed its policies since the data was misused, and now it is trying to audit and ban applications that may be using user information incorrectly.
Cambridge Analytica did not respond immediately to a request for comments.
Kaiser's written testimony in other surveys is as follows:
I must emphasize that the Kogan / GSR datasets and questionnaires were not the only questionnaires and datasets connected to Facebook that Cambridge Analytica used. I am generally aware of a wide range of surveys that were conducted by CA or its partners, usually with a Facebook login, for example, the "sexual compass" questionnaire. I do not know the details of these surveys or how the data was acquired or processed. But I think it's almost certain that the number of Facebook users whose data was compromised through routes similar to those used by Kogan is much larger than 87 million; and that both Cambridge Analytica and other companies and unconnected campaigns participated in these activities.
