I suppose what it is is that smaller questions are answered, bringing along with these answers jargon and special terms, then these special terms are used to define greater special terms, and so on until you end up with a big twisty answer to a seemingly simple question, and people who haven’t read the answers with the smaller special terms look at the twisty answer in understandable bemusement.

Edit: This also happens to be one of life’s big unanswered questions. I had an assignment on it for my MPhil a couple of years ago.
