I believe what you describe is what I have learned to be known as Servant Leadership[0]. I could be totally wrong in my interpretation of your experience and admittingly may be projecting a leadership approach I quite fancy.
Thanks for sharing your experience.
EDIT:
Removed unnecessary qualification in the last sentence.
Kind of, but with a different motivation at inception at least. In a perverse bike shedding variation, in a room of experts, disagreement will tend to root in bringing every matter under the lense of individual expertise. No one wins there, as before addressing the problem, the disagreements tend to focus on context. There is a certain art in giving ownership on the subject matter expertise, while drawing the lines on the overlaps, where argumentation is focused and productive rather than a tug of war to pull the subject in a comfort zone.
Thanks for sharing your experience.
