Description:

'Cambridge Analytica, an American-owned company based in London, was employed by both the Vote Leave campaign and the Trump campaign. Dominic Cummings, the campaign director of Vote Leave, has made few public announcements since the Brexit referendum but he did say this: “If you want to make big improvements in communication, my advice is – hire physicists.”

Steve Bannon, founder of Breitbart News and the newly appointed chief strategist to Trump, is on Cambridge Analytica’s board and it has emerged that the company is in talks to undertake political messaging work for the Trump administration. It claims to have built psychological profiles using 5,000 separate pieces of data on 220 million American voters. It knows their quirks and nuances and daily habits and can target them individually.

“They were using 40-50,000 different variants of ad every day that were continuously measuring responses and then adapting and evolving based on that response,” says Martin Moore of Kings College. Because they have so much data on individuals and they use such phenomenally powerful distribution networks, they allow campaigns to bypass a lot of existing laws.

“It’s all done completely opaquely and they can spend as much money as they like on particular locations because you can focus on a five-mile radius or even a single demographic. Fake news is important but it’s only one part of it. These companies have found a way of transgressing 150 years of legislation that we’ve developed to make elections fair and open.”

Did such micro-targeted propaganda – currently legal – swing the Brexit vote? We have no way of knowing. Did the same methods used by Cambridge Analytica help Trump to victory? Again, we have no way of knowing. This is all happening in complete darkness.

...

We don’t understand it [the internet]. It is not bound by terrestrial laws. And it’s in the hands of two massive, all-powerful corporations. It’s their experiment, not ours. The technology that was supposed to set us free may well have helped Trump to power, or covertly helped swing votes for Brexit. It has created a vast network of propaganda that has encroached like a cancer across the entire internet. This is a technology that has enabled the likes of Cambridge Analytica to create political messages uniquely tailored to you. They understand your emotional responses and how to trigger them. They know your likes, dislikes, where you live, what you eat, what makes you laugh, what makes you cry.'
