We have access to all this information technically, but in reality most people are taking their cues from social media platforms which, being commercial entities, tailor their messages to suit the user. The algorithm sees what you click on and then sends you a steady stream of the same type of stuff to confirm your bias. They just want clicks. They are monetizing the users because as the now old saying goes, if they offer you the product free of charge, you ARE the product. Consequently, the only way for someone to get a broader overview of a given issue requires the person sitting on the toilet to do a bit of research, and most people don't do that because it takes too long. Once they've pinched their morning loaf they put the phone down and wipe.
