For high wisdom, you can never go wrong with fortune cookies. If you could explain what they meant, you would have high int instead of high wisdom.

Players who choose characters with extremely high intelligence, IME, tend to be highly intelligent themselves so are able to play the part well. The same question could be asked, and even with more of a potential conundrum, around playing a character with a much higher level of wisdom.![]()
The flip is also the way to go for players with more knowledge or wisdom than their PC - tell them to make a roll when they try to use capabilities their PC probably should not have... and then tell them no if the roll fails.
Well I've only been playtesting the approach for 30 to 40 years, but I have to say the results look promising....Tell a player "no?" Tell a player who thinks he's smart "no?" Playing with fire, here. I hope it works out for ya.
