Multipliers, Revised and Updated: Unlocking The Secrets of Effective Leadership to Maximize Team Potential

Every organization has them: leaders who somehow make everyone around them sharper, bolder, and more capable — and leaders who do the opposite, quietly shrinking the people they're supposed to develop. Liz Wiseman calls these two types Multipliers and Diminishers, and her research-backed framework makes an uncomfortable argument: many well-intentioned leaders are accidentally in the second camp. The stakes are real. Wiseman estimates that Diminishers utilize only half the intelligence available to them, while Multipliers routinely get two times more. For anyone who manages people — or is managed by someone — that gap is impossible to ignore.

What distinguishes this book from the crowded leadership shelf is Wiseman's discipline with evidence. Each insight is grounded in interviews with hundreds of leaders across industries, and the revised edition folds in years of additional field research to sharpen the original model. The writing is crisp and organized around five distinct Multiplier disciplines, making it easy to locate yourself and identify specific behaviors to change. Wiseman resists the temptation to flatten complexity into inspiration; instead, she gives readers a practical taxonomy they can actually apply the morning after finishing a chapter.
