I watch Jimmy Kimmel and Jay Leno interview people on the street all the time. They can't name their governor, congressman, mayor or the vice president. Sometimes they can't name the sitting POTUS. That's not unlikely in Absolom either.
Knowing the name of the local Ruler is a DC 10 Knowledge:Local check. Knowledge is a Trained Only skill. So for a character to even make that check by RAW they gotta have a rank.
Now I will concede your point that the knowledge skills are written from an outsider's standpoint but that is not actually how they are written. If the rules are followed exactly as written; the PC may not actually know the mayor's name.
I didn't say that a low stat character couldn't identify a fork, I said he may not have the linguistic skills to name it on command. Not the same thing.
The character can speak the Common Tongue; but nowhere does it elaborate how extensive that linguistic skill is. He may know the word King but not the word Monarch.
I know the word Antidisestablishmentarianism but I don't actually know what it means.
The Online document doesn't cover much on Intelligence beyond saying that it governs the ability to Learn and Reason. Then what it's mod effects.
Yes it's the Rule Section.
There are virtually no rules for Role Playing. Aside from the mechanics of Alignment.
Alignment is often reviled for that reason.
So it's an issue of playstyle. I've played in games where not one person spoke In Character for 3 hours. I've played in games where you couldn't speak Out of Character to anyone other than the DM nor could you speak if it wasn't your turn during combat. Lots of things are only lightly touched on other things are incredibly specific.
We can't perfectly model real life with RPG rules, heck we barely model fantasy life with RPG rules. Comparing Jump Skill to Olympic Athletes shows failings in the model. Falling out of a 3rd story window shows a failing in the model. Watch some FreeDiving what's that guys CON score?
"Dude, Where is my House" is a valid issue for a low WIS character.
I went to Savannah GA on a spring break years ago. I drove my cousin to the mall. She was 16, had gone to that mall twice a week for years and didn't know how to get there. Years later she still gets lost on the way to the mall; but she's got a PHD and can answer the most arcane trivia. She's not well modeled by a low WIS stat either. Her sense of direction is just terrible but her Sense Motive is never off.
