I have experienced this same issue many times. But from my experience, I cannot simply pinpoint it to young developers or their education. I have seen this behavior with several older people, university educated, with many years of professional experience. So not just an age/generational thing, in my opinion.

Maybe they have seen so many red herrings that they don't even trust that the error message could contain something useful and relevant? Or maybe they just learned to skim through everything, and don't actually read stuff.
