Managers often describe people as having either a fixed mindset or a growth mindset. The distinction is useful, but real behaviour is less tidy. Someone may welcome feedback in one setting, avoid it in another and become highly persistent when the stakes feel personal.
That complexity matters for companies. Mindset affects how people respond to failure, authority, learning and uncertainty, yet workplace systems can either reinforce or weaken those tendencies. A performance review that punishes every unsuccessful experiment sends a different message from one that examines what the team learned and changes the next decision.
The fixed and growth mindsets
Psychologist Carol Dweck’s research popularised the distinction between fixed and growth mindsets. A fixed mindset treats ability as relatively stable. A growth mindset views capability as something that can be developed through effort, effective strategies, feedback and experience.
The original idea was never a simple instruction to remain positive. In business, a growth mindset does not mean praising effort regardless of the result. It requires a closer look at the quality of the effort, the evidence behind a decision and the adjustments made afterward. Dweck’s foundational paper is available through the American Psychologist.
The framework becomes less useful when it is turned into a label. Calling an employee “fixed” can become another form of judgement, especially when the real problem is a lack of training, unclear priorities or a manager who treats questions as weakness.
Why the binary breaks down at work
Workplaces create conditions that shape behaviour. A talented analyst may take intellectual risks in a supportive team but protect themselves in a culture where mistakes damage promotion prospects. A senior executive may encourage experimentation publicly while demanding certainty in every internal forecast.
This is why leaders should examine systems alongside individual attitudes. Do teams have access to coaching? Are objectives realistic? Can people challenge a senior decision without career consequences? Are failed projects reviewed for insight, or merely assigned blame?
These questions move the discussion from personality to practice. More guidance on translating mindset into management can be found in our Leadership and Strategy coverage.
What the Maellen Theory can add
“Maellen Theory” does not have a clearly established definition in the mainstream psychological literature available for this article. It should therefore be treated as a working editorial lens rather than a recognised scientific theory.
Used cautiously, the lens can address a gap in the fixed-versus-growth debate: people do not develop in isolation. Their behaviour emerges from the interaction between personal beliefs, the meaning they attach to an event and the environment in which they must act.
Under this interpretation, a mindset is only one part of the picture. A person may believe skills can improve but still lack time, resources or authority to practise. Another may appear resistant to change because previous initiatives were abandoned before results could emerge. What looks like a fixed mindset may sometimes be rational caution shaped by organisational experience.
The Maellen lens is most useful when it prompts four practical questions:
- What does the individual believe is possible?
- What incentives are shaping the person’s response?
- What evidence would justify changing course?
- What support or permission is required to act differently?
This approach avoids turning growth mindset into a motivational slogan. It asks whether the organisation has made development credible.
From belief to operating practice
Companies can make the distinction actionable without building an elaborate programme. Managers can begin by separating a person’s current performance from their potential to improve. Feedback should identify the behaviour that needs to change, explain why it matters and establish a way to test progress.
Project reviews also deserve attention. A useful review does not ask only whether a target was met. It examines the assumptions behind the work, the quality of execution, new information that emerged and the decision that should follow. That process gives employees a practical route from failure to learning.
Leaders should also watch their own signals. If they ask for candour but reward only confident answers, the culture will favour performance over discovery. If they promote experimentation but provide no tolerance for measured setbacks, employees will learn to avoid visible risk.
For individuals, the same logic applies. A growth response is not endless persistence. Sometimes the right move is to abandon a weak strategy, seek better advice or change the goal. Progress depends on learning, but learning depends on accurate diagnosis.
A more useful conclusion
Fixed and growth mindsets remain valuable as starting points, especially when discussing reactions to challenge and feedback. They become misleading when treated as permanent identities.
The Maellen Theory, understood here as a working framework rather than an established body of research, offers a broader question: what combination of belief, context and evidence is producing this behaviour? That question is more demanding than assigning a label, but it gives managers something they can actually change.

External research on the relationship between beliefs and achievement should be read with attention to study design, context and the limits of applying psychological concepts across every organisation.
