I was speaking about long-lived unsolved problems that have almost equally long-lived official or semi-official "plans" or "wars" to provide a solution but have not arrived at any true solution. I wasn't speaking of all problems that exist.

> I was speaking about long-lived unsolved problems Yes, and the word "unsolved" in there is the exact selection bias I was referring to. Of course if you look at the universe of "unsolved" problems you don't see any verified solutions! It's a tautological statement. If you were looking specifically at unsolved problems, of _course_ there are no solutions yet. That was the definition of the term!
