Adulthood may not always be fun, but if we consistently resist taking on responsibility, Peter Pan syndrome could be at play.

"All children grow up, except one," says J.M. Barrie in his novel "Peter and Wendy." He was referring to Peter Pan, the boy who didn't want to grow up.

While there's no magic in real life that prevents children from growing up physically, some adults continue to cling to the carefree days of childhood and find emotional and financial responsibility challenging well into adulthood. Peter Pan Syndrome is the common name for this behavior pattern.

What is Peter Pan Syndrome?

Dr. Dan Kiley coined the term "Peter Pan Syndrome" in the 1980s in his book "The Peter Pan Syndrome: Men Who Never Grow Up." A year later, he published "Women's Fear of Being Themselves: The Wendy Dilemma," in which he described the difficulties young women face in relationships with Peter Pans. But what does Peter Pan Syndrome mean ?

It primarily describes people who have difficulty becoming adults . Instead of developing into the socialized aspects of adulthood, these individuals essentially remain in childhood. According to Kiley, people with Peter Pan syndrome behave irresponsibly and may exhibit narcissistic personality traits . This makes it difficult for them to maintain functional social, professional, and romantic relationships. Because people with Peter Pan syndrome refuse to accept responsibility, they tend to blame others for problems.

Note that this is not a recognized mental illness . However, many experts agree that this pattern of behavior can impact relationships and the quality of life of those affected.

In his book, Kiley focuses on outdated, patriarchal notions of gender and sexuality. Many of the criteria he cites are therefore not reflected in a more modern view of Peter Pan syndrome. In 2021, Ondokuz Mayıs University developed an assessment procedure to make Peter Pan syndrome measurable, at least in men. This suggests that this behavior is now being empirically researched, but it does not necessarily mean that it can only affect men. Until science proves otherwise, it is assumed that these characteristics can apply to anyone – regardless of sex or gender. The same applies to Wendy syndrome .

What is Wendy syndrome?

Kiley quickly discovered that there is a female counterpart known as Wendy Syndrome—in reference to Peter Pan's female companion. Wendy Syndrome describes the characteristics of a person who enables their partner to act like Peter Pan. It was originally intended to describe the female counterpart of the adult male, but it applies to anyone, regardless of gender , who enables this behavior. Those who exhibit Wendy Syndrome often mean well and believe they are being supportive. However, when a Peter and a Wendy feed off each other, they reach a dead end that fosters codependency .

Peter Pan Syndrome: What are the typical symptoms?

Because Peter Pan syndrome is n't a clinical diagnosis , experts haven't defined any official symptoms. However, there are some common signs that affected individuals share. These symptoms include behaviors you'd expect from a child or teenager. These include:

Difficulty making decisions
Low motivation
Lack of prospects
Refusal to accept constructive criticism
Refusal to define relationships
Friendship with younger people instead of peers
Emotional outbursts in stressful situations
Entitlement and the expectation that they will be taken care of
Unreliability and negligence
The desire to keep all options open instead of making concrete plans

Furthermore, Kiley lists seven key characteristics of Peter Pan syndrome in his book. It's important to note that these criteria are partly based on outdated, patriarchal notions of gender and sexuality.

Emotional paralysis: Those affected have blunted emotions or express their feelings inappropriately.
Slowness: People with Peter Pan syndrome may be apathetic, procrastinate, and frequently arrive late.
Social challenges: You feel anxious and have difficulty forming meaningful friendships. The result is instead a toxic friendship .
Irresponsibility: Those affected often avoid taking responsibility for their mistakes and instead blame others.
Female relationships: They may have difficulties with maternal relationships and treat future romantic partners as "mother figures."
Male relationships: They may feel distant from their father and have difficulties with male authority figures.
Sexual relationships: Those affected may fear rejection from romantic partners and desire partners who are dependent on them. Learn more here: Fear of Loss .

Since Peter Pan syndrome has not been sufficiently researched, the causes can only be speculated upon. However, there are various possible explanations , which depend largely on the individual and their circumstances. Here are the possible causes of Peter Pan syndrome:

Overprotective parenting: A study from California State University shows that overprotective parenting can encourage the development of Peter Pan-like behavior patterns. In this case, children are raised to believe that the outside world is dangerous. If they don't venture out into the world on their own, they become overly dependent, insecure, and may have difficulty finding their way.
Anxiety: Anxiety can make a successful transition to adulthood difficult for many people. Adults are essentially responsible for supporting themselves, making life decisions, supporting themselves and others, or pursuing employment. Failures can be perceived as personal inadequacies that are difficult to accept without appropriate guidance.
Fear of commitment: Many people with Peter Pan syndrome are afraid of commitment. They may also fear any decision that puts them in a situation from which there is no escape. Rather than taking a risk, they choose not to commit because it is the safer alternative. Learn more here: Overcoming commitment anxiety and fear of commitment.
Loneliness: Desired or perceived loneliness can be debilitating and problematic. In these cases, those affected may regress to childhood to feel loved and supported. Because they crave attention, they may act like a child or refuse to take on more responsibility.
Narcissism: Narcissism is a common factor associated with Peter Pan syndrome. People with narcissistic tendencies believe they are entitled to excessive treatment from others. Their minds are all about themselves. Therefore, they manipulate those around them to get what they want and what they believe they deserve.

The terms Peter Pan syndrome and narcissism are often used interchangeably. But they are different concepts. It is true that many people living with this syndrome also exhibit narcissistic tendencies. However, many people also have narcissistic traits without meeting the criteria for narcissistic personality disorder. Furthermore, not everyone with Peter Pan syndrome exhibits narcissistic traits. While the two terms share similarities (not taking responsibility, blaming others for failures, fear of criticism or conflict), they should not be confused. In narcissism, these behaviors are often accompanied by a devaluation of others and a lack of empathy .

How do you deal with people with Peter Pan syndrome?

While it's possible to encourage and support those affected to make positive changes, it's usually not possible to change someone who isn't ready or willing to put in the work. Instead, communicate your own ambitions, expectations, and life goals. Stopping behaviors that support the affected person in this syndrome (cleaning up after themselves, spoiling themselves, etc.) can also help them recognize the need for change.

Adulthood brings with it many complicated things to think about. In short, being a productive, tax-paying member of society isn't easy. Therefore, it's perfectly normal to sometimes wish you could go back to your teenage years. If you find yourself avoiding necessary aspects of adulthood, like finding a job or maintaining healthy relationships, it's important to challenge these patterns .

Can Peter Pan syndrome be treated?

Therapy is key to successful self-exploration. Therapists can offer unbiased support by helping you examine patterns in your life and recognize how they affect your relationships and chances for success. Peter Pan syndrome is more of a set of behaviors than an official diagnosis.
