I think you're making a whole world of assumption and becoming defensive when there is no reason for that. I asked, because I know a thing or two about the education system and can see what effects it has on students, especially in the humanities; and they are not what should be expected from good education, unfortunately.
Of course everyone can, but to what result? Common sense, knowledge (this one was missing from your previous claim) and intuition, all have their limitations so it's not very wise to rely on those solely. And why either-or? Why only? Why not to combine both for the best outcome? You know, I spent the last 15+ years following political events, learning about political history, among other things, and still don't consider myself expert, far from that. So I consult my understanding with those who know more and listen to them. Lost my way more than once exploring some unknown (to me) lands, only to eventually reach a dead end and realise I should have had listened better. Left traces of those adventures on some forum threads. But I did learn a few things from that, like how to spot a trap a bit quicker, for example.
Here, on the forum rarely anyone comes with a strong conviction, drops it here and doesn't show any interest in other members' feedback. Such people are clearly not into learning which is the very purpose of this place: calibrating our intuition, expanding our knowledge and getting closer to the objective view of the reality. Insisting on one's own views is none of those.
I'm sorry to say that evidence and reports available in your native language are mostly trash, with rather scarce exceptions. Would you be up to the task of finding those? And remember our mantra: Learning IS fun.
