“Research suggests that there are two fundamental paths to influence: dominance and prestige. When we establish dominance, we gain influence because others see us as strong, powerful, and authoritative. When we earn prestige, we become influential because others respect and admire us,” says Adam Grant in his book Give and Take.
DOMINANCE
Influencing through dominance comes from others seeing one as strong, powerful and authoritative.
PRESTIGE
Influencing in this way earns one respect and admiration.
Admins and assistants tend to fall into this category. I would argue that there are important elements in both categories.
