Except it rarely works that way. Because East Heretic Wong Yerk See and the post-Heavy Iron Sword Yeung Gor were generally able to overwhelm their enemies with martial arts, they seldom put their innate cleverness to use. Things that aren't used don't disappear, but they do grow dull from disuse...
Wong Yung, on the other hand, relied on her brains *over* her martial arts, so I think her "active intelligence" might be able trump her father and Yeung Gor's "latent intelligence."
