In the book “Multipliers: How the Best Leaders Make Everyone Smarter”, Liz Wiseman and Greg McKeown analyzed data from 150 leaders and categorized them as Diminishers or Multipliers. Diminishers drain energy from everyone around them, reducing commitment and focus. They need to be the smartest ones in the room, killing off ideas and innovation. Multipliers, on the other hand, amplify others’ intelligence and abilities. They inspire people to overcome obstacles, to generate new ideas, and to deliver results that surpass expectation.
