51kqnzgJqSLMultipliers: How the Best Leaders Make Everyone Smarter is a business book by consultant and speaker Liz Wiseman.

There are two dramatically different types of leaders. The first type drains intelligence, energy, and capability from the people around them and always needs to be the smartest person in the room. These are the idea killers, the energy sappers, the Diminishers of talent and commitment.

On the other side of the spectrum are leaders who use their intelligence to amplify the smarts and capabilities of the people around them. When these leaders walk into a room, light bulbs go off over people’s heads; ideas flow and problems get solved. These are the leaders who inspire employees to stretch themselves to deliver results that surpass expectations.

These are the Multipliers.
