In the programming domain I can at least run something and see it doesn't compile or work as I expect, but you can't verify that a written statement about someone/something is the correct interpretation without knowing the correct answer ahead of time. To muddy the waters further, things work just well enough on common knowledge that it's easy to believe it could be right about uncommon knowledge which you don't know how to verify. (Or else you wouldn't be asking it in the first place)
