Right, the brain seems to have a heuristic that if it hears/sees/etc the same thing, it makes it believe it more. Like if you’ve heard two different people spout the same wrong thing, you’re quite likely to start believing it. So if you’re fed the same thing over and over due to your YouTube persona bucket, you probably become a more devout believer, for better or worse. Receiving a smattering of different opinions probably keeps you in a better place in terms of remaining critical. Maybe staying in a skeptical frame of mind helps inoculate against this somewhat, because you go through the exercise of trying to find counter evidence at the same time, so that you’re essentially feeding your own brain conflicting messages. But that takes effort unless you’re already in the habit. Something to keep in mind, regardless of how correct you think your habitual info channels are. If dissent is stamped out, like it is on many subreddits and Twitter, that’s a pretty bad sign.
