As an example, the last time I played a character with really low wisdom it was a human fighter who also had big strength and big charisma, so I played him as a big grinning handsome chap, with a very positive outlook, who tended to rush in without thinking things through. In play, every time I had an idea he would immediately act on it, regardless of whether it was sensible or not. It made for some interesting scenes, but I could easily foresee others getting fed up with this after a while. That game didn't last long enough to find out, but it was a concern.
So, how would you do it?
