The Dark Sides of Positive Leadership: Why the Good Can Also Be Bad

Positive leadership: what the research actually shows

First the fair side. Positive leadership practices correlate reliably with engagement, retention and self-reported wellbeing. Anyone who treats people decently, sees their strengths and radiates confidence runs a more pleasant system. That is documented and it remains true.

The foundation simply carries less weight than the brochure promises. A 2024 review (Azila-Gbettor et al.) analysed 118 studies on positive leadership and wellbeing: 92.4 per cent cross-sectional designs, a good half convenience samples, 55.1 per cent pure self-reports, and a grand total of 9 longitudinal studies. Data like this establishes associations. On cause and effect it says nothing. People who like their manager also tick the engagement box more generously; successful teams rate their leadership better in hindsight. The arrow points both ways.

On top of that comes a design flaw that Stephen Fineman named as early as 2006 in the Academy of Management Review: many concepts in positive leadership research already contain their result in the definition. “Good leadership” is measured through trust and development, and then predicts, no surprise, trust and development.

And there is a research strand of its own devoted to the reverse. A review by Wang, Long and Peng (2019) analysed 41 empirical studies on the dark sides of positive leadership styles and found negative effects on followers, on teams and on the leaders themselves. The finding behind it has a name: the too-much-of-a-good-thing effect (Pierce and Aguinis, 2013). Practically every leadership variable regarded as positive works along a curve. Trust tips into negligence, autonomy into overload, closeness into favouritism, optimism into denial. For ethical leadership the tipping point has been demonstrated empirically (Stouten et al., 2013). Positivity is nevertheless sold as a straight line: more praise, more meaning, more impact. A doctrine without a dosage.

First dark side: positivity makes you deaf

David Collinson of Lancaster University coined an uncomfortable term in 2012: “Prozac leadership”. Leadership that keeps confidence chemically pure trains employees to gloss over problems or keep quiet about them. Whoever brings bad news is treated as a naysayer, so the news arrives late or never. Collinson developed the argument through the 2008 financial crisis: inside the banks, confidence counted as loyalty and warning about risk as a defect of character.

This is not an isolated finding. A 2025 meta-analysis in Psychology & Health shows clear associations between employee silence and burnout, while speaking up openly goes together with less exhaustion. An organisation that makes dissent expensive therefore pays twice: with worse decisions and with sicker people.

The mechanism comes with a particularly elegant disguise: resistance gets psychologised. Anyone arguing against a project is “afraid of change”. Yet legitimate resistance is often the last functioning control mechanism left. The CEO from the first scene learned this the expensive way: his solution-oriented team had watered the warning down three times, until it was no longer a warning at all.

Second dark side: the happiness imperative exhausts people

The psychologist Iris Mauss and her team showed something paradoxical in a widely cited series of studies in 2011: people who value happiness highly and pursue it strongly feel lonelier and less satisfied, and precisely under favourable conditions. Expectation eats the experience. In the same year, June Gruber, Mauss and Maya Tamir set out systematically when happiness does harm: in the wrong degree, at the wrong time, in the wrong form. Elation during a crisis lowers risk perception. Cheerfulness in the face of loss comes across as cold.

A wellbeing programme with a metric attached turns happiness into an obligation to deliver. Anyone who then suffers loses twice: through the suffering itself and through failing the happiness norm. Emotion research names the price plainly: people who have to display feelings they do not have are keeping up a façade, and this surface acting correlates reliably with exhaustion, cynicism and intention to quit. Unpleasant feelings also carry information: anxiety, anger and exhaustion are data about overload, boundary violations and conflict. Treat them as an attitude problem and you delete the data.

Dreaming has its pitfalls too. Gabriele Oettingen and Doris Mayer separated two forms of thinking about the future in 2002: expectations grounded in experience, and fantasies that idealise. Positive expectations predicted success. Positive fantasies predicted the opposite: fewer job offers, poorer exam results, slower recovery. The reason is measurable (Kappes and Oettingen, 2011): idealised fantasising lowers energy, the organism relaxes as though the goal had already been reached. The picture of the future produced by the family business in the third scene was exactly that: a collective relaxation exercise with a poster.

And the leader? The leader pays first. Permanent confidence in the face of one’s own uncertainty is first-class façade work, only lonelier. At some point, whoever leads is no longer allowed to look tired. The final stage is described by the coaching author Klaus Eidenschink in his book “Das Verunsicherungsbuch. Warum das Gute auch schlecht ist” (2025): actors in a stage play, feigning vitality while inwardly exhausted or frozen.

Third dark side: positivity shifts responsibility

Barbara Ehrenreich dissected this for American culture: where optimism is compulsory, failure becomes a question of character. Inside a company that means resilience training instead of staffing levels, a gratitude ritual instead of a pay round, a mindfulness offer after the reorganisation. The hidden message to the workforce: the work is not too much, you are not yet positive enough.

How concrete this gets is shown by a series of studies by Jay Kim, Troy Campbell, Steven Shepherd and Aaron Kay (2020) in the Journal of Personality and Social Psychology: people seen as passionate are more readily expected to put up with worse treatment. Unpaid overtime appears legitimate, since the meaning compensates for it. Purpose can in this way become the moral charging of exploitation. Generous attention does something similar: the norm of reciprocity (Gouldner, 1960) is among the most stable social mechanisms there is. “After everything she does for me, I can hardly say no now.” It works most strongly on the conscientious, which is to say precisely on those with the highest risk of exhaustion. The loyal leavers of the pharmaceutical CHRO send their regards.

Then there are the questions of power, which simply do not appear in the positive vocabulary. Empowerment in which responsibility travels downwards while budget, priorities and decision rights stay at the top is a shift of responsibility dressed up as enablement. Participation workshops held after the board retreat are more cynical than an honest top-down decision, because they promise involvement and withhold influence. Relationship-oriented leadership produces inner circles: the same three names on every important project, and nobody has to answer for the unequal treatment, because it grew out of affection.

Even the values plaque in the entrance hall belongs on this list. “Appreciation”, “integrity”, “trust”: who would be against them? Terms with no possible counter-position decide nothing. Orientation only emerges where one value has to be weighed against another and something has to be given up. Values that never cost anything are decoration.

Fourth dark side: the cult of strengths and watered-down feedback

“Play to your strengths” sounds humane and usually is. Robert Kaiser and Darren Overfield measured the reverse in 2011 and call it lopsided leadership: leaders who maximise their strengths become one-sided. Decisiveness tips into ruthlessness, confidence into overestimation. And nobody tells them, because the development model has declared weaknesses irrelevant. In HR the same pattern keeps people in roles they are unsuited to; the necessary confrontation simply does not fit the vocabulary. Eidenschink goes one layer deeper: supposed weaknesses are often symptoms of biographical distress. Cover them with strengths and you perfect the pattern, and the “better version of yourself” becomes the polite form of self-rejection.

Related to this is praise inflation. Where recognition becomes a quota, it loses its information value. A feedback culture that wraps every criticism in a sandwich trains recipients to miss the core. Recognition is a currency; it suffers what every inflated currency suffers. A compliment everyone receives regardless of performance comes to feel manipulative. The recipients notice.

That leaves the question of context. What works in a creative team can do damage in an operating theatre; the effect of positive leadership depends on task, maturity and situation. In an acute crisis a team needs clear roles and boundaries more than it needs inspiration. Running the same positivity training for nursing, sales and IT therefore reveals one thing above all: nobody thought about context.

Whoever leads is led

The Heidelberg physician and organisational consultant Gunther Schmidt coined a sentence that unlocks the whole subject: whoever leads is led. Whether leadership takes place at all is decided by those being led, through their responses. Leadership is an interaction, not a possession.

For positive leadership this means: its effect arises in the recipient, nowhere else. A programme can make offers, no more than that. Mandated positivity intended as a steering mechanism is recognised by the team as a steering mechanism and answered accordingly: with a façade, with withdrawal or with cynicism. And it is precisely these answers that then lead the leader. The mood that turns the moment the boss leaves the room is a response.

Seen this way, the symptoms that wellbeing programmes set out to combat are the most valuable thing an organisation possesses: cynicism, absenteeism and quiet disengagement are competent messages about unmet needs. A programme that manages symptoms away destroys information. Eidenschink calls the pattern a flight into health: quick improvements, produced so that the painful part does not have to be integrated.

This perspective clears up something else as well: why positive leadership is so hard to criticise. It is difficult to contradict a concept called “positive”; the counter-position is automatically called “negative”. Success confirms the model, failure was “not implemented positively enough”. A theory confirmed by every outcome is no longer a theory. Eidenschink describes the accompanying figure: whoever is certain of being on the good side becomes an advocate of the true, sitting in judgement over others. Whoever is certain of possessing the good puts other people in the dock. In organisations, the people in the dock are the ones naming the risks.

What mature leadership does instead

None of this adds up to a programme of cynicism; destructive leadership has advocates enough. The defensible position is this: positive leadership works as a complement and fails as a monoculture. It becomes dangerous where it delegitimises the negative, psychologises the structural and mistakes agreement for wellbeing. What follows from that in concrete terms, on three levels?

For you personally: lead positively when it fits, and leave it when it does not. What counts is the ability to do both. Find yourself a place where you are allowed to be at a loss; anyone who is never allowed to be at a loss ends up merely performing. And say the hard things out loud instead of packaging them in celebratory prose. A tough decision communicated with dignity respects those affected more than any sanitised version. Protection, belonging, integrity, recognition: these four things can be left intact even in a termination conversation.

For your team: make dissent an institution rather than a matter of mood. A fixed slot for the worst news of the week changes more than three rituals of praise. In moments of consensus, ask who stayed silent. And give feedback its information value back: praise that everyone receives regardless of performance says nothing any more, and criticism delivered in cotton wool does not arrive.

For your organisation: test impact against independent data, against external assessments and hard metrics rather than against mood curves from the same survey. With every culture programme, ask which structural problem it is currently covering up. A staffing shortage needs staff, not resilience. And get the dosage right: for every positive leadership instrument there is a quantity beyond which it does harm. Anyone who does not know the upper limit does not know their instrument.

The uncomfortable point

Whoever leads sets priorities. Whoever sets priorities disappoints. Whoever promises leadership without this tragedy is describing a leadership that denies it. Positive leadership implicitly promises a world in which everyone grows and nobody loses. That is the friendliest form of self-deception currently on the market.

Perhaps the most important act of positive leadership is therefore one that appears in no programme: being able to listen to bad news without reinterpreting it. Anyone who can do that has no need of the 3:1 rule. Anyone who cannot will not be helped by it either.
