This becomes a bit of a recursive problem for me. I don't have the time to read through every source for everything I read. In practice, I only dig into things I care about, or things that sound fishy based on my own knowledge / experience. This leaves 95+% of information I ingest unverified by me. This may not be an issue at the time (since these are things I care less about), but the problem is I've now formed an opinion about these things based on what I read but not fact checked. Later on that "truth" becomes part of my knowledge base with which I make judgements with. This then end up influencing other decisions downstream which may be important to me. The nasty thing is I don't even know to what extend I'm influenced in this way.
