Two very interesting closing comments at the end of the Cambridge Analytica whistleblower Christopher Wylie’s appearance before the digital, culture, media and sport committee in the House of Commons.

1. People in charge of investigating and regulating data need to understand how relational databases, machine leaning etc. work. At present, they don’t! (Christopher Wylie)
2. There’s been too much focus on the individual level of psychological profiling. It’s not about using psychographics to influence how individuals vote, it’s about a “collective effect,” like the spreading of rumours. They are easier to generate. The impulse to share information. Only Facebook can look into that! But they seem to have a blind spot on it (Paul-Olivier Dehaye).
