We’ve all heard about the impact Facebook had on the 2016 US election — but how much do we really know about what was going on? In this episode we talk to people at the centre of the 2016 Cambridge Analytica scandal and ask if psychological profiling really works. And if voters in Canada are being targeted. We also look at the darker side of online targeting —the thousands of abusive tweets hurled at women and candidates of colour and how it impacts our democracy.
