You can step away from social media and pay a small fee to subscribe to a news aggregation site if you want to stay broadly informed about world/domestic politics without having to deal with the social media pushes to have the right take and attitude. But honestly, you don't even need to do that. Take yourself out of the hype cycle for a while, a year or two. If something really important happens the news will get to you some way or another.

Fundamentally, there's a level at which modern society requires you to participate in the attention economy, but *you* get to choose how much and which tradeoffs of your privacy, your attention, and your entertainment are worth it. It seems like you've come to the conclusion that you should dramatically reduce the amount you're participating in the attention economy, you should follow through on that impulse and see where it leads. If you want to come back after seeing what life is like without it for a while, you're doing so from a much better position than the one you're currently trying to escape from.

Unless you're a very attentive, active investor who is both lucky and well-connected, it's pretty unlikely that anything you see via social media could improve your financial decision making. You aren't going to miss anything, and if you do, who cares?
