The files were released by the UK’s Digital, Culture, Media and Sport Committee.
They detail some of the work undertaken by Cambridge Analytica and companies it has been linked with, including SCL Group, Global Science Research and Aggregate IQ.
“In one document, SCL said that encouraging people “not to vote” might be more effective than trying to motivate swing voters.
Describing its work in a Nigerian election, SCL Global said it had advised that “rather than trying to motivate swing voters to vote for our clients, a more effective strategy might be to persuade opposition voters not to vote at all”.
It said this had been achieved by “organising anti-election rallies on the day of polling in opposition strongholds” and using “local religious figures to maximise their appeal especially among the spiritual, rural communities”.
It boasted of devising a political graffiti campaign to create a youth “movement” in Trinidad and Tobago and of disseminating “campaign messages that, whilst ostensibly coming from the youth, were unattributable to any specific party”. It said as a result “a united youth movement was created”.
In Latvia, it said it had recognised that “unspoken ethnic tensions” were “at the heart of the election”.
“The locals secretly blamed the Russians for stealing their jobs… armed with this knowledge, SCL was able to reflect these real issues in its client’s messaging,” the document said.
The files spell out how SCL helped the UK’s Foreign and Commonwealth Office “in strategic planning to counter violent jihadism” in Pakistan.
“I wouldn’t only recommend them, I’d work with them again in an instant,” wrote an official, whose name has been redacted.”
