Facebook 'dark ads' can swing political opinions, research shows

Ads targeted using profiles generated from individual voters' stated interests are more successful in shifting attitudes according to Online Privacy Foundation

Using "psychographic" profiles of individual voters generated from publicly stated interests really does work, according to new research presented at the Def Con hacking conference in Las Vegas, Nevada.

The controversial practice allows groups to hone their messages to match the personality types of their targets during political campaigning, and is being used by firms including Cambridge Analytica and AggregateIQ to better target voters with political advertising with so-called "dark ads".
