The way I conceive of things, the information were provided with, if tapped into everything available these days is like trying to drink out of a firehose, lethal for the brain. Maybe those of us who lived through /b/ in the early aughts are uniquely able to have a flood of absolute shit and still be able to pick out the gold, but I think it comes down to two things in this case, having a well tuned bullshit detector (read as much as you can about science and history and philosophy and humanity and why we are the way we are) and pruning the sources of information you expose yourself to. For example the only subs I browsed on reddit were r/con or subs similar in theme. But reddit is just too far gone these days so this place is filling that void. You don’t ever want to cut yourself off from “the mainstream” though, if you see what they’re fixating on you have a good idea on things to look into (the whys and whos of whatever story they’re shilling on)
