I think it's a very big problem when learning things that almost everything can be made to sound plausible when you don't have real world experience to compare them to.
It's also very easy for those plausible-sounding ideas to stick around for so long in your mind that you sort of start taking them for granted, and we tend to be really bad at scrutinizing those things we take for granted.
It's only much later, when it just isn't working, and you're relutantly forced to come face to face with the difficult fact that some of the things you thought you knew really well were just some loudmouth opinion on the internet.
