It feels like an absurd interpretation doesn't need to be given equal validity in just about any area of disagreement in life. (The tricky part is how absurdity is delineated...).So one player’s interpretation is as valid as another….
And it feels hard to me to argue that this is absurd. (After a page of quibbling about what is meant by 10%, and an argument that it would only be unobservable in the short run and eventually would show out, and then referring to the thread on how long campaigns run). It would have shown a lot more in earlier editions where they were prereqs for a lot of things..It is completely reasonable to read the rules and conclude that 6 Intelligence means that you are 10% worse than average at cognitive tasks. Which is a difference that might not even be observable.
