I feel like (1.) is undersold by some orders of magnitude. There is a vast, vast quantity of bad advice circulating and being amplified in echo-chambers. If you need a particular piece of advice then by definition your ability to discern it from adjacent bad advice is not good.
Even if you do manage to identify good advice, a (1b.) is required stating something like "all advice is situational, and again, if you really need advice for this situation then by definition you aren't equipped to tell reliably whether any particular piece of advice really applies."
Put those together and you get a double Sturgeon's Law effect where 90% of all advice is bad, and 90% of good and seemingly relevant advice is inappropriate for your specific circumstances, and so your chances of a randomly selected piece of legit-sounding advice being actually good and applicable are around 1%.
