I watched the Brexit movie the other day, and although there's speculation as to it's validity, it is food for thought.
It's rather scary how data is used and manipulated in such a way as to brain wash certain groups of society into doing pretty much anything 'they' want, be it buying the latest gadget, subscribing to the latest faddy diet, or the next path your country should head.
It's easy to sit here spouting that many of us are above these tactics, but the scary thing is most of us aren't, and we are all influenced in one way or another to buy things we don't actually need, simply through targeted marketing watching our internet searches, and even the location/shops we visit.
Ever been into John Lewis, and noticed several minutes an advert on your social media about the same shop you were in earlier? They even have an acronym for it. LBA Location based advertising. Very clever.
