When Strengths Go Too Far: The Line Between Useful and Destructive

A client asked me recently whether inflexibility is always a positive trait. I said no. When used at the wrong time or pushed too far, it becomes a real obstacle. He was surprised - he knows me as someone who usually sees quirks and peculiarities as strengths. I explained it this way: these quirks are like pepper. Used well, they make the dish spectacular. Used too much or on the wrong dish, they ruin it entirely.

This is the part of strengths-based work that most people skip. They identify the strength, celebrate it, and stop there. But every behavioural strength carries an associated weakness - and that weakness has a limit.

Allowable and Non-Allowable

In Belbin Team Roles, each role represents a cluster of behaviours with specific strengths and specific associated weaknesses. The associated weakness is not a flaw. It is the predictable cost of a useful contribution.

Scepticism - the ability to analyse, question and see risks others miss - is an allowable weakness. It slows decisions down, and that can frustrate people. But it also prevents bad decisions. Inflexibility - resistance to change that protects proven processes - is an allowable weakness. It blocks innovation sometimes. But it also protects stability when the team needs it.

The problem starts when the allowable weakness crosses a line and becomes non-allowable. When scepticism turns into constant criticism of every idea regardless of merit. When inflexibility shuts down all discussion of improvement, not just unnecessary change.

The distinction is not theoretical. It is the difference between a team member who adds value through their caution and a team member who has become an obstacle to everyone else's contribution.

How to Spot the Line

Watch behaviour over time, not single incidents. Everyone has a bad day. The question is whether the pattern has shifted. Is the scepticism now applied to everything, even ideas that deserve consideration? Is the resistance now blocking conversations, not just protecting processes?

Watch the team's reaction. When one person's behavioural pattern starts crossing the line, the team signals it before anyone names it. Enthusiasm drops. People stop sharing ideas. Frustration becomes visible. If the most creative person in your team has gone quiet, something in the environment has changed - and it is usually someone else's overused strength that caused it.

Have the conversation directly. Not about personality. About behaviour and its effect. Most people who overuse a strength do not realise it. Their intention is protective - they are trying to safeguard quality or prevent mistakes. The impact is the opposite, but they cannot see it from where they sit. Mats Soomre, Belbin Accredited Team Coach, uses observer feedback through Belbin profiles to give people a view of themselves they cannot get alone: "When someone sees that three colleagues independently described the same behavioural pattern, the conversation changes. It is no longer opinion against opinion. It is a pattern that needs attention."

This is why observer feedback changes everything. Only 17.7% of people have a coherent self-view. Read Self-Awareness: You Think You Know Yourself.

What to Do When the Line Has Been Crossed

Help the person see the impact - not as blame, but as information. Often the most effective intervention is showing them what their behaviour costs the team in concrete terms: ideas not shared, decisions delayed, people disengaged.

Overused strengths are one of the five hidden demotivators in teams. Read Before You Motivate, Remove What Demotivates.

Adjust the timing, not the trait. A sceptical thinker does not need to stop being sceptical. They need to hold their analysis until the idea has had room to develop. A detail-focused contributor does not need to stop checking quality. They need to trust the process enough to let others contribute before the final review.

Use the team as the solution. If one person's strength is overwhelming the team, the answer is rarely to suppress it. The answer is to balance it with complementary strengths - someone whose natural energy and optimism can absorb the scepticism without being crushed by it, or someone whose adaptability can work alongside the inflexibility without resentment.

The Personal Test

I know this pattern from my own life, not just from coaching others. My most trusted partner is behaviourally my opposite - analytical where I am intuitive, structured where I am spontaneous, precise where I am broad. We have strong and sometimes heated discussions. We see the world differently on almost everything. But the combination produces decisions that neither of us could reach alone.

Over 35 years together - and I have said publicly that Belbin saved our marriage. Because once we could see the behavioural patterns clearly, the disagreements stopped being about who was right. They became about what the situation needed.

That is what happens in teams too. When people understand that their colleague's annoying trait is the flipside of a genuine strength, the conversation changes from "why are you like this?" to "how do we use this well?"
