I like this one. I'm sure some of it was just throwing Charisma a bone, but I think it makes some sense, too.I have to wonder about horror... did they just decide, "Let's throw charisma a bone?"
Wisdom covers things like willpower. To quote from Werewolf: The Apocalypse, a high willpower/wisdom means "Nerves of steel or brains of jello." Intelligence tells you that the dragon can eat you. Wisdom allows you to ignore the urine running down your leg and at least try to not bolt like food.
Charisma is force of personality and sense of self. You may not be able to stop yourself from running from Cthulhu, but you can avoid being permanently scarred by it. Repeat after me, "I know who I am. I know who I am. I know who I am."
