As the Risk Factor identified as most important by this post I'm starting a discussion on Too Individual/Character Based.
Please start answers to this question discussing each of the examples, adding more examples, and discussing just where to draw the line. Once we've reached a consensus and updated the descriptions given here we'll then create a meta post to point people to and a custom close reason.
Currently the preferred name is Too Character Based suggestions for alternatives are welcome.
You are asking questions about an individual and how they will or should act, not about building a world.
Asking about the actions of individuals is not Worldbuilding so is off topic for this site. Creation of historical figures, authority figures, pantheons, etc for a world is on topic but anything that asks whether someone would or should do something is not.
How to Fix:
Rephrase the question to remove all references to an individual and any "should" or "would" parts of the questions. "Would Joe Marine 17 climb this hill wearing his backpack" is off topic. "Could a well trained marine wearing a 30kg weight backpack complete a 1 mile route with 500' of ascent in 10 minutes" is on topic.
Only the person who is writing a character can decide how that character will act in a given situation. Worldbuilding can determine what is possible for that character to do, but the choices that the character makes given those possibilities is down to that individual character.
