Let's say Int is about logic, calculating, learning and remembering, and Wisdow is more the good sense, good judment, wit, being sensible or prudent, self-control, psychological maturity and resistance against mental stress and sanity against madness. With Int you can the best way to earn money, but with Wis is about the best way to spend and manage it.
And I have said my goal is a d20 system variant easy to be used and comfortable for players and 3rd party publishers. I have suggested some attribute are optional, even only used by a PC but not for the rest of the group (for example Technique or Spirit). And I also I have suggested some attributes would be only substats, working as bonus feats, for example appearance.
What about adding Acuity (Perception + Astuteness) and Courage as two new abilities scores? They could be suggested in some future UA articles about modules or optional rules.
The problem with Wisdom is not how its defined but rather what it does in game. What are the mechanics of rolling a prudence or maturity check? ie When confronted with an in game choice what does prudence actually do for a character? (The same question applies to Courage really).
Can you give any examples of use?
