Please do note the delicious irony here :

I don't see much good in associating rationality with extreme caution.

I don't think that teaching people to expect worse case scenarios increases rational thinking.

Which in essence looks suspiciously like cautiously assuming a bad case scenario in which this story won't help the rationality cause, or even a worst case scenario in which it will do more wrong than right.

If you want to go forth and create a story about rationality, then do it. Humans are complex creatures, not everyone will react the same way to your story, and anybody who thinks they can accurately predict the reaction of all the different kinds of people who'll read your story (especially as this story hasn't even been written yet) is either severely deluded as to their ability, or secretly running the world behind curtains already.

When you are older, you will learn that the first and foremost thing which any ordinary person does is nothing.
