Oh it's far more sinister than that. Social media that tailors your views to what you will return to keeps you seeing confirmation bias articles that they think will keep you, the product engaged for it's customers, the advertisers. the net result of that is you only get news that further divides us, creates a narrative that is different for you than it is for someone from the other tribe, both getting this tailored experience that creates and maintains divide, the unintended consequence of this, more that they dont care about? is division.
