The appointment has been in the calendar for weeks. An important project, a presentation in front of the team, expectations running high. Then, that morning, the childcare falls through. The car will not start. And the colleague whose input the whole thing depends on calls in sick. Some people would fall apart at this point. Others keep juggling, reorganise on the fly, stay calm. Researchers call this ability resilience: the capacity to handle stress and crisis without breaking under them. And they claim it can be trained, like a muscle.
But is that actually true? Or is resilience ultimately a matter of genes, childhood, luck? Science has been searching for answers for decades. What it finds is far more complicated than any promise on a self-help shelf.
There Is No Such Thing as the Born Survivor
The history of resilience research begins in Hawaii. Starting in 1955, psychologist Emmy Werner followed almost 700 children on the island of Kauai over four decades. Many grew up in poverty, experienced violence, had few opportunities. Yet roughly one third developed into stable, successful adults regardless. Werner drew a conclusion from this that has shaped the field ever since: resilience can be learned.
Since then, the concept has shifted. Initially, resilience was seen as a fixed trait, a character feature you either had or did not. Today, researchers understand it as a dynamic process that changes, adapts, and can be trained. The Leibniz Institute for Resilience Research in Mainz, the only institution of its kind in Europe, investigates the neurobiological, psychological, and social mechanisms behind it. Neuroscientists, physicians, and psychologists work there in an interdisciplinary team. Their goal: to understand why some people stay healthy under stress while others become ill.
Professor Klaus Lieb, the institute's scientific director, highlights one central finding: there is no single, universal resilience. Every person has a different profile of strengths and weaknesses and responds differently to different stressors. A one-size-fits-all resilience training that delivers the same content to everyone falls short.
What Science Actually Knows
The evidence is mixed. A large meta-analysis evaluating 37 studies with a combined 16,348 working adults (Vanhove et al., 2016) found that resilience training can work. The programmes improved job performance, reduced psychological complaints such as burnout and depression, and increased wellbeing. The effects, however, were often small and faded over time. Short-term results, within the first month after training, were stronger than long-term ones.
A separate meta-analysis examined resilience training in children and adolescents. Of 118 studies on coping strategies, 83 on psychiatric symptoms, and 116 on wellbeing, most showed positive effects. Yet these were so modest that the researchers classified them as "no longer of practical significance." Only in the area of behaviour, such as sleep problems or alcohol use, were there measurable small improvements.
The problem: many resilience training programmes are not grounded in scientific concepts. A team led by Professor Dirk Lehr of Leuphana University Lüneburg reviewed 92 studies and found that the majority of programmes had been assembled more or less freely. There is no scientific consensus on what a resilience training should actually consist of. Some focus on mindfulness, others on cognitive behavioural therapy, still others on relaxation techniques. Approaches are frequently combined without any clarity about which element is doing the work.
"Resilience is a dynamic and lifelong process that unfolds in the interplay between person and environment, and varies across different life domains and phases," explain researchers from the Leibniz Institute for Resilience Research in Mainz.
There is also a more fundamental problem: resilience takes time to develop. Most training programmes last only a few weeks, and follow-up checks or refresher sessions are rare. Critics such as the Canadian researchers Forbes and Fikretoglu argue that many programmes are "selling old wine in new bottles." They call for training to align more closely with current resilience concepts, and for repetition and outcome monitoring to become standard practice.
The Four Pillars of Resilience
Despite all the criticism, four core factors emerge from the research as demonstrably contributing to resilience: self-efficacy, optimism, nurturing relationships, and self-care. The GETON resilience training developed at Leuphana University Lüneburg focuses on precisely these four areas. Evaluated in parallel scientific studies, it relies on daily exercises via an app and six online lessons.
Self-efficacy means the conviction that you can handle challenges through your own efforts. Someone who believes they have influence over their life approaches stress differently from someone who feels at its mercy. Optimism does not mean glossing over problems; it means expecting that solutions are possible. Nurturing relationships sounds soft but is hard work: people who can draw on a solid social network in a crisis recover more quickly. And self-care is not a wellness buzzword but the ability to recognise and take your own needs seriously.
That sounds simple. Yet a gap often opens between knowing and doing. Most people understand, in theory, what would be good for them. They simply do not act on it. This is the real challenge of resilience training: not transmitting knowledge, but changing behaviour.
When Training Becomes a Job Requirement
Resilience has long since arrived in the corporate world. Faced with rising workloads, growing complexity, and constant change, many employers have turned to resilience programmes. The logic: make your workforce more robust, reduce sick days, raise productivity, cut costs.
This development is contested. Critics see it as the commercialisation of mental health. Rather than improving working conditions, the idea is to train people to endure more pressure. Resilience becomes an individual assignment instead of an impetus to address structural problems. Those who break down simply have not trained enough. This logic shifts responsibility from the system onto the individual.
The research, however, shows that resilience training works best when embedded in a comprehensive framework. Alongside behavioural prevention, which targets the individual, structural prevention is needed to improve the surrounding conditions. Workplace design, leadership culture, and social support within teams play at least as large a role as individual skills. Resilience training alone cannot compensate for working conditions that make people ill.
Genes or Experience?
A twin study examining more than 1,300 families with over 2,600 twins arrived at a striking finding: differences in resilience are 70 to 77 per cent attributable to genetic factors. That sounds like fate, like something fixed. Yet research also shows: genes are not rigid programmes; they respond to environment and experience. Epigenetic processes can flip genetic switches without altering the DNA sequence itself. Stress, trauma, and positive experiences alike leave molecular traces.
At the Leibniz Institute in Mainz, researchers are investigating precisely these mechanisms. Using animal models, they examine the biochemical, neurophysiological, and genetic processes that enable resilience. Running in parallel is the Mainz Resilience Project, a long-term study with young people in the transition between adolescence and adulthood. Through imaging techniques and behavioural analyses, the researchers are trying to understand how resilience forms and develops.
Professor Oliver Tüscher, director of the Department of Psychiatry and Psychotherapy at the University of Mainz, emphasises the role of appraisal style. What matters is not the stressors themselves but how people perceive and interpret them. A positive appraisal style, one that looks for possible actions in difficult situations rather than focusing on threats, can substantially reduce the experience of stress.
What Remains After the Training Ends?
The question of whether resilience can be trained cannot be answered with a simple yes or no. The research shows: it works, but not equally well for everyone, not in every context, and not permanently. Resilience training can help when it is scientifically grounded, tailored to individual needs, embedded in a comprehensive framework, and sustained over time through refresher sessions.
But it is no miracle cure. It cannot undo traumatic experiences, heal working conditions that cause illness, or compensate for social inequality.
Emmy Werner's Kauai study revealed something else as well: the resilient children had almost all had at least one reliable person in their lives. Someone who believed in them, who was there when things got hard. No app can replace that, no training programme, no mindfulness course. In the end, resilience may be less a question of individual strength than a social phenomenon.
And perhaps that is the most important insight of all: resilience does not grow in isolation. It emerges in relationships, in community, in structures that hold people up. That cannot be trained quite as simply as a muscle. But it can be shaped.
