The Accidental Diminisher
How well-intentioned leaders unknowingly shut down the intelligence around them
The Accidental Diminisher is one of the most surprising findings from Wiseman's research: very few Diminishers understand the restrictive impact they have on others. Most had been praised for their personal intelligence throughout their careers and assumed their role as boss was to be the smartest person and have the best ideas. Others had once had the mind of a Multiplier but had worked among Diminishers so long they had gone native, absorbing diminishing practices and worldview without realizing it.
The pattern follows a nearly universal three-step reaction when leaders encounter these ideas. First, resonance: they recognize they have worked for both types. Second, realization: they see Diminisher tendencies in themselves, ranging from trace amounts to chronic patterns. Third, resolve: they build conviction to become more of a Multiplier but feel overwhelmed by the magnitude of the change.
Accidental or not, the impact on teams is the same. Leaders may be getting only half the true brainpower of their team. Common Accidental Diminisher behaviors include being the idea person who generates more ideas than the organization can execute, being the always-on leader who jumps in with answers before others can think, being the rescuer who takes back problems instead of letting people struggle and learn, and being the pace-setter whose own rapid performance inadvertently signals that others cannot keep up.
- Most diminishing is accidental, not intentional
- Being praised for intelligence throughout your career can set you up to become an Accidental Diminisher
- Working under Diminishers for extended periods causes you to absorb their practices unconsciously
- The impact on your team is the same whether diminishing is accidental or intentional
- The path of least resistance in most organizational cultures is the path of the Diminisher
- It is not hard to be a Multiplier, but it is easier to be a Diminisher
- Give yourself permission to be a better leader than your boss
- 1. Recognize the PatternAcknowledge that most leaders have some Diminisher tendencies, often rooted in the very strengths that made them successful. Being the smartest, fastest, or most experienced person in the room can lead to behaviors that shut others down. Look for signs: Does your team wait for your answer before offering theirs? Do people bring you problems but not solutions? Does capability seem to cap at your own capacity?Pro tipAsk your team directly: 'What do I do that might inadvertently shut down your thinking or contribution?' Be prepared to listen without defending.WarningThe biggest blind spot is believing you are the exception. Virtually all leaders who encounter this framework see some Diminisher in themselves.
- 2. Identify Your Specific Accidental Diminisher TypeCommon types include the Idea Fountain who generates more ideas than the organization can execute, the Always On leader whose energy and enthusiasm inadvertently silences others, the Rescuer who takes back work and problems when people struggle, the Pace Setter whose own performance sets an impossible standard, and the Rapid Responder who answers so quickly that others stop thinking.Pro tipYour team already knows which type you are even if you do not. Use a 360-degree assessment or honest conversations to identify your specific pattern.WarningDo not try to fix all patterns at once. Pick the one that has the biggest negative impact and focus there first.
- 3. Take the 30-Day Multiplier ChallengePick one specific practice within one discipline and work it consistently for 30 days. This focused approach avoids the overwhelm of trying to change everything at once. Start small, be consistent, and let the results build momentum for further change.Pro tipChoose a practice that directly counters your identified Accidental Diminisher tendency. If you are an Idea Fountain, practice asking 'What do you think?' before sharing your ideas.WarningDo not announce a grand transformation. People will be skeptical if you declare you are becoming a Multiplier overnight. Let changed behavior speak for itself.
- 4. Work the ExtremesRather than trying to develop all five disciplines, focus on two extremes. First, neutralize your biggest Diminisher weakness by moving it to an acceptable middle zone. Second, take your strongest Multiplier discipline and turn it into a towering strength. Research shows that having just one distinguishing leadership strength nearly doubles perceived effectiveness.Pro tipYou do not need to turn weaknesses into strengths. You just need to make sure they are not actively undermining you. Then invest energy in amplifying what you do best.WarningIgnoring a significant Diminisher weakness while developing strengths can undermine your progress. Shore up the vulnerability first, then build on strengths.
During the research for Multipliers, Wiseman and McKeown were surprised to discover that most Diminishers had no idea they were diminishing others. Many had risen through the ranks on personal and intellectual merit and simply assumed leadership meant being the smartest. As Wiseman coached executives after publishing her findings, she found a nearly universal reaction: people recognized both types from their experience but then saw Diminisher tendencies in themselves. One executive captured this by saying that he had been living in Diminisher land so long that he had gone native. This pattern was so prevalent that it became a central concept in helping leaders change.
