The sum total of things going on in the world is far more than any one human being can process. The function of the news media (either human or algorithmic) is to cherry-pick the stories that are presented to users. Because they are cherry-picked, they necessarily present a distorted picture of reality. In the days of the big-3 monopoly of broadcast TV, they were usually cherry-picked to support national unity and common American culture; as the news media got more competitive, they started cherry-picking ones that would hold viewer attention ("if it bleeds, it leads"), and then as we switched to Internet news and algorithmic feeds they are algorithmically chosen to maximize engagement.
