Nobles use the nuture argument too, claiming that someone trained from childhood to perform a job is likely to be good at it.
You are correct.
However, that argument really only started once large portions of a population stopped buying into the Divine Right myth. I would envision that the RoM genetic testing actually showed predisposition; one that would have to be carefully nurtured and monitored and coupled with training to create a leader. Even then, many such genetic candidates would be unsuitable because of prediction towards anti-social behavior or earlier socialization may have made the candidate unsuitable for leadership. Such "leadership science" perhaps would have been accepted during the RoM with a certain jaundiced eye by Terran populations of the time who looked at it in the same way that most of us chuckle what we do during "management training" or similar week-long courses.
It would only be after the Long Night which saw history and myth rewritten by those in power that the tests would have gained a mythical power approaching that of destiny or divine right and all the stuff about training and so on would be secondary to having the right genes ("blood").
