Are You A Multiplier Or A Diminisher?

April 29, 2026 - By Liz Wiseman, Researcher, Executive Advisor & CEO Of The Wiseman Group | New York Times Bestselling Author Of Multipliers

Comment on the podcast by Ian Munro, CEO, Legitimate Leadership: At Legitimate Leadership we spend a lot of our time and energy highlighting the primary role of INTENT in establishing legitimacy for our leadership. This is as true today as it was nearly 40 years ago when the Legitimate Leadership Model was crystallising. It is also not the full story. Benevolent INTENT is necessary, but it is not enough. INTENT also needs to be evidenced in our mindsets and behaviours. Liz Wiseman’s “Accidental Diminsher” – sometimes a well-intentioned leader who is simply insecure, or too quick to save – is a case-in-point. At Legitimate Leadership we are frequently asked whether it is possible for people to experience our INTENT differently from how we intend. The answer is easy. Yes. Of course. And that is why podcasts such as these are so critical. They allow us to work on our mindsets and behaviours so that, over time, our INTENT is experienced as intended more often than not.

Incidentally, Wiseman’s five disciplines, when well-intended, are wholly consistent with the Legitimate Leadership Model. We encourage all leaders to continuously work on all five:

  1. Becoming a talent magnet
  2. Creating intensity not stress
  3. Debating decisions
  4. Extending challenges
  5. Instilling ownership and accountability

Our summary of this podcast: In this month’s leadership reflection, Liz Wiseman invites us to reconsider a fundamental question: Is our presence as leaders expanding or limiting the intelligence and capability of those around us?

Based on research with more than 150 executives globally, Wiseman distinguishes between Diminishers, leaders who unintentionally create dependency by stepping in, giving answers, and taking control, and Multipliers, who unlock others’ potential by creating space for thinking, contribution, and ownership. The difference is not intention or talent, but mindset. Multipliers operate from a belief that people are capable and resourceful, and lead accordingly.

She identifies five key disciplines of Multiplier leadership: acting as a Talent Magnet by recognising and deploying people’s strengths; creating a high-support, high-challenge environment as a Liberator; stretching people beyond their comfort zones as a Challenger; fostering robust thinking through inclusive debate as a Debate Maker; and transferring real ownership as an Investor.

A particularly powerful insight is the concept of the Accidental Diminisher, leaders who, through enthusiasm, expertise, or care, unintentionally limit others. Stepping in too quickly, always having the answer, or rescuing too soon can send a subtle message: “I’ve got this, you don’t need to.” Over time, this shapes cultures of dependence rather than growth.

This perspective strongly echoes the principles of Legitimate Leadership, in which the leader’s role is to develop others’ capability, confidence, and accountability. Both approaches challenge leaders to move away from control and towards development, from being the answer to building people who can find answers.

The invitation this April is one of honest reflection:

Where might you be unintentionally diminishing those around you? And where is there an opportunity to multiply?

The encouraging message is that Multipliers are not born; they are developed. With awareness and intentional practice, every leader can learn to amplify the intelligence and potential of their team.
