The research behind the buzzwords

Phrases like “Peter Pan syndrome” and “smile mask syndrome” make states of mind easy to picture. But most of them are not formal diagnoses. Here we reread six of these expressions, one by one, through the research behind them.

Peter Pan syndrome: maybe adulthood simply arrives later

“Peter Pan syndrome” is a term the psychologist Kiley (1983) used in a popular book to describe men who avoid responsibility and refuse to grow up. It has no diagnostic criteria.

The developmental psychologist Arnett (2000) offered another perspective. In industrialised societies, as education lengthens and work and marriage come later, the years from roughly 18 to 29 have become a distinct stage called “emerging adulthood” — a time of identity exploration, instability and open possibilities. So taking on adult roles later is not necessarily a sign of individual immaturity. Still, if you keep avoiding responsibility and relationships or work repeatedly fall apart, that pattern is worth looking into.

The smile mask: when feelings are pushed down behind a smile

“Smile mask syndrome” is a name given in the 1990s by the Japanese psychiatrist Makoto Natsume to people who must always smile and are quietly wearing out inside.

In research terms, this is close to emotional labour and emotional suppression.

  • The sociologist Hochschild (1983) called flight attendants’ managing of their smiles as part of the job emotional labour.
  • A meta-analysis of three decades of research found that surface acting — putting on emotions you don’t feel — is clearly linked to emotional exhaustion (Hülsheger & Schewe, 2011).
  • People who habitually suppress emotions tended to feel fewer positive emotions and to be less satisfied with their relationships (Gross & John, 2003).

If you are so drained that words fail you when you get home, it matters to secure time and people with whom you don’t have to put on a face. You can look at your current load with OIYO’s emotional labour test.

Digital narcissism: do selfies breed self-love?

Twenge et al. (2008) reported that American college students’ narcissism scores rose from one generation to the next, warning of a “narcissism epidemic.” Later research analysing larger datasets, however, found that narcissism actually declined slightly between the 1990s and the 2010s (Wetzel et al., 2017).

Some studies find a weak link between posting many selfies and narcissism scores (Sorokowski et al., 2015), but there is little causal evidence that selfies create narcissism. People post photos for many reasons: keeping records, connecting, having fun. If you’re curious about your own tendencies, see the narcissism test.

Fatalism: “nothing’s going to change anyway”

Rotter (1966) distinguished an internal locus of control, the belief that outcomes depend on your own actions, from an external locus of control, the belief that they depend on luck or others. Seligman’s research on learned helplessness showed that repeated uncontrollable experiences can make people stop trying at all, and later work revised the theory towards the idea that a sense of control can be learned and regained (Maier & Seligman, 2016).

Personality changes more than we think, too. A meta-analysis of longitudinal studies found that conscientiousness and emotional stability rise steadily on average from the twenties into middle age (Roberts, Walton & Viechtbauer, 2006). You can’t change the pages already written, but the unwritten pages are still there.

Putting yourself last: is looking after yourself selfish?

The habit of always caring for others first and leaving yourself for last is hard to sustain. Neff (2003) proposed self-compassion: treating yourself like a close friend when things are hard. A meta-analysis found that people with higher self-compassion have lower depression and anxiety (MacBeth & Gumley, 2012).

Self-compassion is not self-justification or laziness. It is closer to acknowledging mistakes without beating yourself up. Looking after yourself is, in the end, also a way of keeping the strength to help others for the long haul. You can check how you treat yourself with OIYO’s self-compassion test.

Addiction and “hungry ghosts”: a thirst that never ends

In Buddhism, hungry ghosts are beings with huge bellies and needle-thin throats who can never be satisfied however much they eat. In In the Realm of Hungry Ghosts (Maté, 2008), the physician Gabor Maté borrowed this image to urge us to understand addiction as an attempt to soothe pain.

There are several ways to explain addiction.

  • The brain disease model: repeated use changes circuits for reward, motivation and self-control (Volkow, Koob & McLellan, 2016). It has critics, but the need to take brain changes into account is still seen as important (Heilig et al., 2021).
  • The role of environment: in the “Rat Park” experiment by Alexander et al. (1981), rats in a spacious environment with companions drank less morphine water. Later replications, though, have been mixed.

Put together, addiction is a problem in which brain changes, pain and environment are intertwined. That’s why treatment often combines medication, counselling and rebuilding relationships. Rather than seeing it only as a lack of willpower, asking for help is the first step.
