I think you are mistaken about the relevance of high school. For a lot of people, high school was a traumatic and/or violent experience that they would rather forget. Does making high school "suddenly relevant" put up an artificial barrier-to-entry for candidates that were able to overcome bad experiences in high school and move on to something better? What about candidates who say something like "high school was awful and I got out as quickly as I could"? Maybe you have a bias in hiring toward candidates who are good at "making stuff up that sounds good"?

How do you deal with adversity? How do you deal with peer pressure? How do you motivate yourself to work on things that feel irrelevant? How do you choose your hobbies and the people you associate with? Those are important things to assess in a potential colleague. And this is just one potential angle on how one might assess them.
As for "making stuff up that sounds good", you are correct, some people are better at that than others. Fortunately we have clear and objective measures of that to work with so forewarned is forearmed.
