What Is Optimism?

A commentary by Victor Perton, That Optimism Man, Updated September 2026

“Optimism is a belief that good things will happen and that things will work out in the end.”

That is my definition of optimism. I try to live the life of an optimist: to remain personally optimistic and to foster optimism in others. I have spent years researching optimism, writing about it, teaching it and asking people about it. I have asked thousands of people, “What makes you optimistic?” Their answers have strengthened my conviction that optimism matters deeply in how we live, lead, decide, recover, create and respond to difficulty.

There are two important ideas in the definition.

By “good things will happen”, I mean that the future contains real possibilities for love, progress, discovery, recovery, achievement, kindness and human flourishing. Difficulty is real, but it is never the only possibility before us.

By “things will work out in the end”, I do not mean that every hardship will disappear or every loss will be reversed. I mean that difficulty does not determine the whole future: good remains possible, choices remain, and what we do can still matter.

There is a deep historical resonance here. In the fourteenth century, Julian of Norwich wrote: “All shall be well, and all shall be well, and all manner of thing shall be well.”  Her conviction arose not from an absence of suffering, but from faith that suffering did not have the final word.

The future can be good without being the future we originally imagined. That, too, is part of what I mean when I say things can work out in the end.

Optimism begins as a belief about the future. Living as an optimist means allowing that belief to shape what we notice, the choices we recognise and the actions we take.

That leads directly to one of my central conclusions.

Why Optimism is Realism

Optimism is realism.

Reality contains problems and possibilities, risks and opportunities, failure and learning, constraint and human agency. To see only what can go wrong is not realism. It is an incomplete view of reality.

The optimist sees the world as it is. The optimist does not assume that the present determines the future.

Optimists recognise risk, uncertainty, disappointment, injustice, loss and failure. They experience anxiety, sadness, anger and fear. Optimism faces all of these things while remaining open to what can change and what people can still do.

The optimist sees what is wrong and asks what can be done, sees what has failed and asks what can be learned, and faces uncertainty while remaining open to possibility.

The future is not fixed.

Circumstances change. People learn. Relationships can be repaired. Problems can be solved. New discoveries alter what is possible. Human beings cooperate, invent, adapt and begin again.

Good thinking sees the problem in full. Optimism keeps us from assuming that the problem determines what happens next.

What is sometimes called “realistic optimism” is, in my view, simply optimism properly understood: facing reality while believing that better outcomes remain possible.

This does not relieve us of the obligation to think well.

Optimism is one thing. The accuracy and rationality of particular beliefs are another. When a forecast is unrealistic, call it unrealistic. When confidence exceeds the evidence, call it overconfidence. When assumptions are wrong, correct the assumptions.

A bleak forecast is still a forecast. Its bleakness does not make it more accurate. What matters is the quality of the evidence and reasoning behind it, not whether the conclusion sounds optimistic or pessimistic.

Optimism can coexist with error, but error should be named accurately. Optimism bias is a systematic misjudgement of risk; overconfidence is confidence beyond the evidence; wishful thinking substitutes desire for judgement.

Wishful thinking substitutes desire for judgement. Optimism does not. It can face unwelcome evidence and still believe that better outcomes remain possible.

The optimist follows the evidence without assuming that today’s evidence exhausts tomorrow’s possibilities.

Changing your mind when the evidence changes is not a failure of optimism. It is part of realism.

Sometimes the next wise step is to stop, change course or let go. Optimism is commitment to possibility, not commitment to a particular plan.

Things can go badly without everything being lost. Optimism looks again at reality and asks what remains possible now.

Optimism, Uncertainty and Possibility

Uncertainty is part of the human condition.

We can investigate, forecast, plan and prepare, but we cannot know the future with certainty.

The future is uncertain, and that uncertainty leaves room for possibility, human agency and change.

Optimism lives neither in certainty nor fantasy. It lives in the real space between what the evidence tells us now and what human beings may still make possible.

Optimism does not promise certainty about how things will work out. It recognises uncertainty while remaining open to better outcomes.

Evidence that a problem is serious does not necessarily establish that it is permanent, insoluble, or destined to worsen.

When certainty is unavailable, possibility becomes a vital part of good judgement.

Across history, people have solved problems that once appeared beyond solution. Diseases have been prevented and treated. Technologies have transformed lives. Laws and institutions have changed. Enemies have made peace. Communities have rebuilt after disaster. People have recovered from illness, disappointment and loss.

Progress is not automatic.

It is made possible by thought, courage, cooperation, ingenuity, persistence and action.

Optimism sustains engagement. When the future is uncertain, belief in better possibilities gives us reason to keep learning, adapting, persisting and acting.

Optimism and Agency

Optimism and agency belong together. Optimism strengthens agency, our capacity to choose and act, because belief in a better future gives us reason to use the power we have. When we believe that what we do can help shape what comes next, we have reason to learn, decide, persist, contribute and act.

We cannot choose everything that happens to us.

People plainly do not have equal power over their circumstances. Illness, poverty, discrimination, war, grief, disability and other forms of hardship can severely constrain choice.

Hardship can greatly restrict our choices, but constraint is not always the same as complete powerlessness. Sometimes the remaining agency is small, sometimes collective, and sometimes it lies simply in the next response we choose.

I learned this from my grandmother and my mother.

My grandmother was imprisoned in the Soviet Gulag. Even there, she retained the spirit and determination to “outlive communism and the Soviet Union.” She could not control the dictatorship that imprisoned her, but she could refuse to let it determine her whole inner life or her belief in the future.

And she did outlive it. She outlived the Soviet Union and the dictatorship that had imprisoned her.

My mother became a stateless refugee. Her life taught me another expression of the same truth: even when circumstances strip away security, home and certainty, people can retain the capacity to choose, endure, rebuild and believe in a better future.

Optimism asks:

What can I do now?

Sometimes the answer is ambitious. Sometimes it is a phone call, an apology, professional advice, patience, a change of direction or helping somebody else.

Optimism vs Positivity, Hope, Confidence and Resilience

Optimism is often confused with other valuable human qualities. The distinctions matter.

Positivity is about how we feel. Optimism is about what we believe about the future. We can be optimistic without feeling positive.

You can be sad and optimistic. You can be anxious and optimistic.

You can grieve deeply and remain optimistic. The belief that good things can still happen does not diminish the reality of what has been lost.

Hope and optimism overlap, but they are distinct. Hope reaches towards a desired future and can endure even when the outcome is uncertain or beyond our control. For many people, hope also has a spiritual dimension, grounded in faith in God or a higher power.

Optimism is a belief about the future: that good things will happen and that things will work out in the end.

A person can be optimistic without feeling confident about a particular task. Confidence and self-efficacy concern capability; optimism concerns expectations about the future.

Optimism is a key underpinning of resilience and persistence. Resilience is our capacity to withstand, adapt to and recover from difficulty; persistence is our willingness to keep going. Optimism gives both a forward-looking foundation: the belief that better outcomes remain possible and that continuing to act can still matter.

These concepts can reinforce one another, but they should not be collapsed into one another.

Conceptual clarity matters. If every favourable feeling, prediction or positive expectation is labelled optimism, the word loses its usefulness.

Can optimism be learned?

Optimism can be learned, practised, strengthened and shared.

Research supports the proposition that optimism can be strengthened, but not that everyone starts from the same place or responds in the same way.

Our habits matter.

What we notice matters. The questions we ask matter. The language we use about ourselves, other people and the future matters. The company we keep matters. The actions we take matter.

We can practise noticing what is working as well as what is failing. We can notice progress. We can practise gratitude. We can imagine our best possible future. We can learn from setbacks rather than allowing a setback to define the future.

And we can ask:

What makes me optimistic?

I have found this question remarkably powerful.

It does not tell people what to think.

It invites them to look.

What people have Taught Me about Optimism

I have asked “What makes you optimistic?” in classrooms, boardrooms, conferences, community gatherings, interviews and conversations across the world.

There is no single answer.

People tell me about their children and grandchildren. They speak about partners, parents, teachers and friends.

They talk about young people and the possibilities each generation brings.

They talk about nature: gardens, oceans, mountains, animals, sunlight, rain and changing seasons.

They talk about faith, prayer, meditation and spiritual life.

They talk about science, medicine, technology and human ingenuity.

They talk about kindness, strangers helping strangers and communities coming together in difficult times.

They talk about education, discovery and the human capacity to change.

They talk about service and the satisfaction of contributing to something larger than themselves.

The sources differ, but patterns recur.

People find optimism in relationships, meaning, beauty, faith, service, progress and evidence of human capability.

I have often watched people’s attention shift as they answer. They remember something good that had slipped from view, think of someone they admire, notice progress and begin talking about possibility.

This is why “What makes you optimistic?” has become more than a question in my work.

It is a practice.

Optimism Grows between People

Optimism is personal, but its consequences are not. Beliefs about the future shape how people relate to one another, how leaders lead and how communities and nations respond to difficulty.

Optimism can be shared because our beliefs about the future do not remain entirely private. Through language, example, encouragement and the questions we ask, we can help others notice possibility and recognise their own agency.

Our expectations can encourage or discourage. Our attention can help another person recognise progress, capability or opportunity that they had overlooked.

Our example matters.

I try to remain personally optimistic and to foster optimism in others.

National Optimism

The same principles apply to a nation.

National optimism means facing problems honestly while retaining confidence in our capacity to solve them, make progress and build a better future. A country can contain many personally optimistic people and still become nationally pessimistic when citizens can no longer connect their own hopes to a believable shared future.

That matters because national pessimism can become self-reinforcing. If people come to believe that decline is inevitable, they may become less willing to invest, participate, cooperate and take constructive risks.

National optimism strengthens the opposite impulse: the confidence to contribute, reform, build, innovate and persevere.

But national optimism cannot be manufactured by slogans.

It requires better performance, stronger agency and a credible sense of shared future.

Optimism and Leadership

This matters especially in leadership.

In an age of uncertainty, optimistic leadership matters more, not less. The optimistic leader does not promise certainty. The leader helps people face reality, see possibility, recognise what remains within their power and act.

In uncertainty, leadership is not about predicting the future. It is about helping people navigate it. Optimism matters because it keeps possibility, agency and action alive when certainty is unavailable.

Fear of uncertainty can make people search for certainty that no leader can honestly provide.

The optimistic leader offers something better: candour about what is known, honesty about what is uncertain, confidence that useful action remains possible and trust in the capacity of people to contribute.

The optimistic leader creates room for uncomfortable truth. Bad news is not a threat to optimism; it is information about reality and therefore part of deciding what to do next.

People do not need a leader standing at a podium telling them how optimistic the leader feels.

The leader's task is to unlock the optimism within people, not by telling them to be optimistic, but by helping them see what is possible and what they can do.

Good leaders tell the truth about difficulty. They listen to concerns and welcome unwelcome information. They make credible progress visible, invite ideas and give people opportunities to contribute their judgement.

They strengthen agency.

They help people distinguish what can be known, what can be tested and learned, and what must be navigated with judgement.

One of the best questions a leader can ask is:

What makes you optimistic?

The answer tells us something about what people value, what they believe is working and where they see possibility.

Leadership is not confined to titles.

Parents lead. Teachers lead. Coaches lead. Friends lead. Neighbours lead.

The leader really does look like the person in your mirror.

Optimism and Courage

Optimism and courage often travel together.

It takes little courage to expect good things when everything is going well.

Courage becomes more important when the evidence is mixed, the outcome uncertain and the way forward unclear.

Optimism does not remove fear. It can help us act despite fear.

It does not remove uncertainty. It helps us navigate uncertainty.

It does not make hardship disappear. It helps us continue looking for possibility, choice and the next wise step.

Hardship is not good because it reveals strength. But sometimes, in hardship, we see courage, love, generosity, ingenuity, faith and service with unusual clarity.

We discover what people will do for one another.

We discover capabilities in ourselves and others that we may not have noticed before.

And sometimes we discover that even when much has been taken from us, something remains within our power.

What does research tell us about optimism?

Psychologists commonly study dispositional optimism, the general expectation that good rather than bad outcomes will occur, using validated measures such as the Life Orientation Test-Revised.

No single study establishes the case for optimism. The stronger picture comes from converging evidence across longitudinal studies, meta-analyses and intervention research.

Decades of research have linked higher measured optimism with important outcomes in health and ageing, while intervention research indicates that optimism can be strengthened.

A 2026 study extending this work into cognitive ageing found that higher optimism was associated with a lower subsequent risk of dementia.

These findings are important, but association is not causation.

Health, behaviour and human performance have many influences.

Good research should make us more precise, not more extravagant.

The evidence gives us reason to investigate optimism seriously and to keep testing when, where and how it makes a difference.

Living the life of an Optimist

For me, optimism is ultimately something to live.

I try to face reality clearly and keep possibility alive.

I remember that the future is not fixed.

I ask what remains within my power.

I try to take the next wise step.

I look for good people doing good work.

I practise gratitude.

I learn from setbacks.

I try to remain personally optimistic when life is difficult and to foster optimism in the people around me.

Faith and spiritual practice are important sources of optimism for me. Other people find optimism in family, friendship, nature, science, beauty, service, community or purpose.

We do not all need to draw optimism from the same source.

What matters is discovering what strengthens ours.

My definition remains:

“Optimism is a belief that good things will happen and that things will work out in the end.”

Living as an optimist means taking that belief seriously.

See reality clearly.

Keep possibility alive.

Recognise that your choices matter.

Act where you can.

Take the next wise step.

Help others see possibility too.

And ask yourself the question I have asked thousands of people:

What makes you optimistic?
