Multipliers are leaders who look beyond their own genius and focus their energy on extracting and extending the genius of others. They get more from people by accessing and growing people's intelligence and capability. In contrast, Diminishers drain intelligence and capability out of people and organizations. They focus on their own intelligence and resolve, believing they are the smartest person in the room.

Multipliers operate with a growth mindset, assuming people are smart and will figure things out. They see intelligence as continually developing, and believe their job is to bring the right people together and create an environment that liberates people's best thinking. Diminishers have a fixed mindset, assuming intelligence is scarce and static. They think people will never figure things out without them, so they need to keep doing the thinking for everyone.

Multipliers utilize five disciplines that differentiate them from Diminishers:

1. Attract and optimize talent as Talent Magnets rather than hoard resources and underutilize talent as Empire Builders.

2. Create intense environments that require people's best thinking as Liberators rather than suppress thinking as Tyrants.

3. Extend challenges as Challengers rather than give directives as Know-It-Alls.

4. Drive sound decisions through debate as Debate Makers rather than make abrupt, centralized decisions as Decision Makers.

5. Instill ownership and accountability as Investors rather than drive results through personal involvement as Micromanagers.

Multipliers get at least twice as much from people as Diminishers by extracting people's full capability. They also extend people's intelligence by stretching them to contribute more than they thought they had to give. Multipliers are hard-edged managers who create genius around them by fully utilizing people's intelligence and capabilities. We can move towards being Multipliers by examining our assumptions and adopting their practices.
