The Mask That Costs You the Room

Leadership becomes expensive when too much attention is spent managing the impression of leadership.

You can hear it in the language people use when they step into more senior roles. “I need to look more decisive.” “I need to sound more authoritative.” “I need to be more visible.” “I cannot let them see uncertainty.” Sometimes those adjustments are sensible. Leadership is a role, and roles require adaptation. A manager speaking to five people does not communicate in exactly the same way as a chief executive addressing five hundred. A leader in a crisis may need to be more direct than they are in a development conversation.

Adaptation is not the problem. The problem begins when the role becomes a performance so heavy that the person starts protecting the image instead of doing the work. That is the mask that costs you the room.

Authenticity is a difficult word

Authenticity has become one of those leadership words that sounds useful until we ask what it actually means. In popular advice, it often means: Be yourself. Speak honestly. Show vulnerability. Do not pretend. That sounds reasonable. It is also incomplete. Leaders should not say everything they think. They should not disclose every emotion. They should not treat impulse as honesty.

They should not refuse to develop because “this is just who I am”. And they should not confuse consistency with rigidity. The research literature is more complicated too. Authentic leadership has been associated with positive outcomes, but the construct overlaps strongly with other leadership models, especially transformational leadership. A 2016 meta-analysis by Banks and colleagues found a strong true-score correlation between authentic and transformational leadership and concluded that the two constructs were difficult to distinguish cleanly in parts of the literature.

More recent work has pushed this criticism further, arguing that leadership research has accumulated many overlapping style labels that often explain similar behaviours with different names. That matters because leadership is easier to improve when we talk about behaviour. Not labels. So I prefer a more practical definition. Authenticity is behavioural coherence. It is the degree to which your actions remain recognisably connected to what you say matters.

The mask is not always fake

People often create a professional mask for understandable reasons. A naturally quiet person is told they need more presence. A warm leader is told they are too soft. A careful decision-maker is told they are too slow. A new manager watches an admired senior leader dominate meetings and concludes that domination is what authority looks like. So they adapt.

Sometimes the adaptation works. They speak earlier. They become clearer. They set firmer boundaries. That is development. But sometimes they start copying the surface behaviour without understanding the function underneath it. They become louder because someone else was respected while being loud. They become colder because somebody once mistook warmth for weakness. They become faster because hesitation looked dangerous. They become certain because uncertainty felt unsafe.

That is different. The question is not whether the behaviour is “really you”. The better question is: Does this behaviour help you lead better, or only help you look more like your idea of a leader?

Performance requires attention. So does impression management. If a leader is monitoring their voice, posture, expression, status and perceived authority throughout a difficult conversation, part of their attention is no longer available for the conversation itself. That does not mean self-monitoring is always harmful. Good communication requires awareness. The problem is over-monitoring. In sport, I see the same pattern when an athlete becomes too conscious of how they look while performing. The movement becomes less natural because attention has moved away from the task and towards the self.

Leadership can produce its own version of this. The person is no longer only deciding. They are also watching themselves decide. They are no longer only listening. They are also evaluating whether they appear in control while listening. That extra cognitive work can make leadership less responsive. The room changes while the leader is still managing the image.

Coherence matters more than theatre

Teams do not need leaders who behave identically in every situation. They need behaviour they can make sense of. A leader can be warm in one conversation and firm in another. They can be collaborative during exploration and directive during an emergency. They can admit uncertainty about the future while remaining clear about the next action. None of that is inconsistency.

The problem appears when behaviour becomes difficult to explain from the outside. A standard matters on Monday and disappears on Thursday. A leader asks for challenge, then punishes it. They say people should speak early about problems, then react defensively when someone does. They talk about autonomy, then override every decision. The issue is not that the leader has shown two sides of themselves.

The issue is that words and behaviour are drifting apart. That gap is expensive because people start adapting to the gap rather than to the stated principle.

Authenticity is sometimes used as permission for poor self-regulation. “I say what I think.” “I do not sugar-coat things.” “People know where they stand with me.” Sometimes that is clarity. Sometimes it is aggression with a better story attached. A leader has more responsibility for the impact of communication than an ordinary participant in the room because authority changes how words land. That does not mean becoming vague or polite at the expense of truth.

It means making the message useful. If performance is poor, say so. If a decision was wrong, say so. If a standard was missed, explain it. But ask whether the communication helps the other person understand what happened and what needs to change. Truth without function is often just discharge. That is not authenticity. It is emotional convenience.

Vulnerability is not dumping

The same problem appears at the other end. Leadership advice often encourages vulnerability. That can be valuable. A leader admitting a mistake can reduce defensiveness and make it easier for others to speak honestly. A leader saying “I do not know” can be more useful than pretending to have certainty. But disclosure has to serve the work. There is a difference between: “I made the wrong call. Here is what I missed and what we are changing.” and: “I have no idea what we are going to do.” Both may be honest.

They do not have the same effect. Leaders do not have to hide emotion. They do need to know where to place it. The team is not there to regulate the leader. That burden belongs elsewhere: with peers, mentors, coaches, partners or appropriately qualified professionals. Anybody can describe their values when nothing is at stake. The interesting part begins when the values become inconvenient. A leader says fairness matters. What happens when the high performer breaks the rule? A leader says honesty matters. What happens when the information is embarrassing? A leader says challenge is welcome. What happens when the challenge is directed at them?

A leader says people matter. What happens when the quarter is bad? This is where values become observable. In mental-performance work, I am always more interested in what changes under pressure than in the description somebody gives of themselves. Pressure narrows choices. It exposes defaults. It reveals which behaviour has been rehearsed enough to survive discomfort. That is why authenticity is not discovered in a personality exercise.

It is tested in behaviour.

Leadership style should be flexible

Another problem with the authenticity conversation is the idea that every leader has one true style. That is too static. Leadership happens in different contexts. A young team may need more structure. An expert team may need more autonomy. A crisis may require speed. A strategic discussion may require more tolerance for uncertainty. A performance conversation may require directness.

A development conversation may require patience. A leader who refuses to adapt because adaptation feels “inauthentic” is not protecting integrity. They are protecting habit. The challenge is to expand behavioural range without losing the principles underneath it. That is development. You can learn to be more direct without becoming cruel. You can become more visible without becoming theatrical. You can make decisions faster without pretending certainty.

You can show warmth without lowering standards. You can become more authoritative without becoming louder. The behaviour changes. The values do not have to.

This is one reason I am cautious with leadership typologies. They can be useful as prompts. They become limiting when people turn them into identity. “I am an introverted leader.” “I am a visionary.” “I am a coaching leader.” “I am a decisive leader.” These labels can quickly become explanations for behaviour that should still be examined. Research on leadership styles has increasingly raised concerns about construct proliferation and overlap. A 2025 review in the Journal of Management Studies argued that many leadership measures share so much variance that the field may learn more by focusing on observable behaviour than by continuing to add style categories.

That is a useful direction. Instead of asking: What kind of leader am I? Ask: What does this situation require from me, and which behaviour will help without violating the standards I want to lead by? That question is harder. It is also more useful.

Feedback reveals the gap

Most people are poor judges of the effect they have on a room. Not because they are dishonest. Because they are inside their own intention. They know what they meant. Other people only experience what happened. That gap is why feedback matters. But vague feedback produces vague development. “Be more authentic” is almost useless. “People stop challenging you after you interrupt the first disagreement” is useful. “You become much more controlling when deadlines tighten” is useful.

“You say you want concise updates, but you ask so many follow-up questions that people now overprepare everything” is useful. “You sound certain before the evidence is settled” is useful. Behaviour gives the person something to work with. Identity gives them something to defend. A leader’s coherence affects whether people believe speaking up is worth the risk. Psychological safety does not mean everyone feels comfortable all the time. It means people can raise concerns, ask questions, acknowledge uncertainty and admit mistakes without expecting interpersonal punishment simply for doing so. Amy Edmondson’s work made this concept influential, and later meta-analytic research has linked psychological safety with learning, information sharing and performance-related outcomes.

A leader does not create that environment by announcing that the door is open. They create it by what happens after someone walks through it. That is where consistency matters. If the leader asks for candour and then reacts badly to candour, the behaviour teaches more than the statement. People learn quickly.

Three questions I would use instead of “Am I authentic?”

The first: What do I say matters, and where does my behaviour contradict it? The second: What changes in me when pressure rises? Do you become louder? Faster? More controlling? More withdrawn? More certain? Less curious? The third: Which behaviour have I adopted because it works — and which because I am afraid of how I will be perceived without it? Those questions are more useful than asking whether you are “being yourself”. Leadership is not a search for an untouched self hidden underneath the role.

It is the development of a person who can carry more responsibility without losing behavioural coherence. Authority comes from several places. Competence. Role. Judgement. Consistency. Follow-through. The ability to make difficult decisions. The ability to explain them. The ability to remain useful when the room becomes uncomfortable. None of these requires a particular personality performance. A quiet leader can have authority. A warm leader can hold standards. A reflective leader can make fast decisions when necessary. A direct leader can still listen.

A leader does not need to resemble the last successful person who held the role. They need behaviour that works, principles that remain visible and enough self-awareness to notice when pressure is turning development into performance. That is what I mean by authenticity. Not “be yourself”. Not “say everything”. Not “never change”. Build range. Keep coherence. And make sure the person people meet under pressure is still recognisably connected to the standards you claim to lead by.

ALTIUS Note

This article uses authenticity as a practical concept of behavioural coherence rather than as a claim that one leadership style is universally superior. Research on authentic leadership reports positive associations with important outcomes, but the construct overlaps substantially with other leadership models and should not be treated as a uniquely established explanation of effective leadership.
