I Worry About The Intelligence Of Our General Population

Why do so many people on here ask such horrible, incomplete and open ended questions like "why did I do that" or "what did you think would happen" and then never explain Wth they're talking about?? Is it just due to the horrible state of education today, mental laziness or a total lack of awareness of how confusing they're being?
I find it very aggravating.
What's your opinion on it?
