I dunno about that Joe. As a climber, I am not a natural, and I've had to actually work at it to remain mediocre for 36 years now. No one has ever described my climbing ability as brilliant. Nonetheless, if things go sideways, I'm a good person to have as a partner. That's partly a function of experience - time and effort - and has nothing at all to do with being a "natural."
Character is another important aspect in a solid partner, and that also has nothing whatsoever to do with ability.
