There's not enough time in the day for you to "fact check" every piece of purported information you come across. You're also not an expert in all areas despite your Gell-Mann amnesia. At some point you're going to have to rely on some sort of external "fact check".
I don't see the need to pay attention to every bit of so-called information streaming by. When there are topics I care about I will do what's necessary to form my own opinion, as I did with covid and the mRna injections.
