Becoming a Leader Who Multiplies Intelligence
Have you ever worked for someone who made you feel smarter, more capable, and more motivated than you thought possible — or, on the flip side, a boss who left you second-guessing your every move? In Multipliers: How the Best Leaders Make Everyone Smarter, Liz Wiseman and Greg McKeown argue that the difference between these two experiences comes down to one crucial distinction: some leaders amplify the intelligence of the people around them, while others unintentionally (or deliberately) drain it.
Wiseman calls these two archetypes Multipliers and Diminishers. Diminishers are the ‘geniuses’ who hoard decision-making and control, believing that only they have the answers. Multipliers are the ‘genius makers’ who, by trusting and challenging others, double the intelligence and capability of their teams. Her research — drawn from over 150 executives across industries at companies like Apple, Microsoft, and Intel — concludes that people give twice as much of their capacity to Multipliers as they do to Diminishers.
Why This Matters
In today’s world of “new demands and insufficient resources” (as Stephen R. Covey describes in the book’s foreword), leaders can’t afford to waste the intelligence that already exists in their teams. Genuine innovation requires leaders who multiply capability rather than extract it. The book helps readers recognize both traits in themselves and provides a humane but rigorous roadmap for shifting from Diminishing to Multiplying behavior.
The Two Mindsets
At the heart of the Multiplier philosophy lies two contrasting assumptions about human intelligence. Diminishers operate from scarcity: they believe intelligence is static, rare, and centered in themselves. Multipliers operate from abundance: they assume that intelligence is dynamic and widespread. As a result, Diminishers control, while Multipliers trust. Diminishers tell, Multipliers ask. Diminishers are the bottleneck; Multipliers open the gates and let ideas flow.
The Five Disciplines
To act on these assumptions, Multipliers engage in five distinct disciplines. Each taps into a leader’s ability to unlock the latent genius of others:
- The Talent Magnet: Attracts great people and uses them at their highest point of contribution.
- The Liberator: Creates an environment where people can think freely but also feel accountable for excellence.
- The Challenger: Pushes the team to go beyond what they already know by asking bold questions and reframing problems.
- The Debate Maker: Leads sound decisions through rigorous, inclusive debate — not through decree.
- The Investor: Entrusts ownership to others, teaches what they know, and expects people to deliver results autonomously.
What the Evidence Shows
Wiseman’s research reveals that Multipliers not only extract more performance but also expand the intelligence of their teams over time. Whereas Diminishers might get short-term obedience, they leave long-term disengagement and mediocrity in their wake. Multipliers inspire “exhausting but exhilarating” work — the kind that pushes people to new levels of insight and ability. In turn, these leaders create organizations that are self-sustaining, resilient, and capable of navigating growth or scarcity alike.
Who This Book Is For
Wiseman and McKeown wrote Multipliers for anyone who leads others — executives, teachers, coaches, parents, and even community leaders. They emphasize that most Diminishers aren’t tyrants but Accidental Diminishers: well-intentioned experts who simply don’t realize the cost of taking control. The good news is that anyone can learn the disciplines of a Multiplier through awareness, small experiments, and deliberate practice. Across its seven chapters, the book explores how to cultivate each discipline, prevent common diminishing behaviors, and become what Wiseman calls a “Multiplier of Multipliers.”
