I took it another way, where Wisdom specifically controls skills like Perception and Intuition. Basically, skills that allow your character to notice things.

Let’s say an NPC tells a lie, and you ask whether or not they’re lying. You see that you rolled a 1 on the Intuition check. This means you (as the player) know you can’t trust when the DM says the NPC is being truthful. But your character believes the NPC, because you obviously failed the Intuition roll. And that’s where the metagaming comes into play, with the player finding alternative ways to be able to act on what they believe was a lie, even though their character believes something to be a truth.

By hiding the Intuition roll from the players, it obfuscates the pass/fail, and eliminates the entire “player knows someone was lying but their character doesn’t” metagame.
