I'm about as well armed as a person can be when it comes to being able to suss out what I'm being told: I've been online for 30 years (and thus understand how information spreads online and how digital communities work), I have an MLIS (understand how news and information was transmitted historically + how most citizens are taught [or not] media literacy + I understand things like the replication crisis in the sciences), I was raised by an accountant (I'm economically literate/understand financial incentives), and I've worked in nonpartisan political/civics communication (I'm aware of what every side is saying or can get that info in ~5-10 minutes). I can even read multiple other languages - French, Arabic, and Mandarin - so I'm not limited to the anglosphere for my information.
I still have low confidence in almost everything I'm told, and doing proper investigations into all of it is excessively time consuming, terrible for my mental health, and frequently impossible/difficult without institutional affiliation for things like being able to read primary academic sources that are being reported on.
How is the average person supposed to navigate this? There's literally no way.
