A couple of things stood out for me.
Quoter from the Guardian:
None of the techniques described in the document are illegal. However, the scandal over Cambridge Analytica’s acquisition of data from more than 50 million Facebook users is lifting the lid on an industry that has learned how to closely track the online footprint and daily lives of US voters.
CA did not doing anything illegal, or so it appears, they simply harvested user profiles from Facebook and then used targeted adverts on the most used social media sites in much the same way as Google, Amazon, Apple and many other sites do every day. It is the modern way.
The other was the shock felt by CA staff when they visited Trump's campaign HQ.
“There was no database of record. There were many disparate data sources that were not connected, matched or hygiened,” she said of the process of ordering, sorting and cleaning enormous data sets. “There was no data science programme, so they weren’t undertaking any modelling. There was no digital marketing team.”
So they gave them a Persuasion Digital Marketing: Process flow chart that any GCSE pupil could have produced and they showed them mock-ups of the type of things they could do on YouTube and Google search - using paid ads, and off they went.
The press bnarons of yesteryear would have loved to have been able to do those things instead of only relying on billboards, TV and radio ads and their own publications.
Am I bothered? Not particularly. Am I bothered that millions of people take these things on board without question? I most certainly am!
