It’s fun stumbling upon psychological concepts in unexpected places. I remember first learning about the Johari Window (an obscure framework for thinking about the limits of self-knowledge) in the Robert Galbraith novel The Cuckoo’s Calling (2013). It happened again the other day. I was enjoying the action thriller Nobody’s Hero (2024) by M W Craven – my middle-aged version of brain rot – when the hero Ben Koenig invoked the ‘Peter Principle’ – the idea that people tend to get promoted to the point of maximum incompetence.

Koenig is already a curious character for anyone interested in psychology. He has Urbach-Wiethe disease, which has calcified his right amygdala – apparently rendering him incapable of feeling fear (a handy attribute for an action hero). By dint of his training with various special forces, he’s also a repository of fun psychological wisdom, such as the Peter Principle, which he draws on to explain why the assassins have chosen to murder a bunch of mid-ranking infrastructure experts, rather than their superiors.

I checked it out, and the Peter Principle is a genuine concept that originated with a bestselling, semi-satirical book of the same name in 1969, co-written by two Canadians, the educationalist Laurence J Peter and the playwright Raymond Hull. There’s a simple logic to their idea – you keep performing well, you keep getting promoted, until you reach a managerial role at which you struggle and so you don’t get promoted again. Various studies have confirmed there’s a truth to the logic, at least in the context of sales, the military and academia.

I’m going to add the Peter Principle to my mental dictionary of psychological concepts – and use it as a reminder not to rest on my laurels. We can’t assume that the skills and knowledge that served us well in the past will be enough for whatever challenges we face in the future.

Try everything twice

Starting in college, I adopted a new life motto: ‘Try everything twice, because the first time could be a fluke.’ I knew I needed a change. My teenage self had been stubborn and overly certain about the world. That version of me liked what they liked, and that was that. But as I entered adulthood, I started to see how my rigidity was hurting me. By dismissing people, opportunities and experiences out of hand, I was missing out.

So I started giving everything chances – at least two. I applied this to different foods, workout classes, styles of dress, and even dates. I revisited a study group that I’d avoided after our first session together (because they seemed awkward and too quiet), and soon got to know them as a witty and thoughtful group of friends. Saying ‘yes’ at least twice to different social events and party scenes helped me figure out what I truly enjoy.

Over time, this practice, I suspect, even changed my personality, strengthening my tolerance for things I would’ve previously written off and giving me a newfound curiosity. As someone who writes about psychology, I came to understand this change in terms of openness to experience: a dimension of personality that includes inquisitiveness, willingness to entertain new ideas, imagination, and adventurousness. There is no doubt in my mind that changing this personality trait – which, research shows, is indeed possible to do – has made me a happier person.

But I’m also a better person now, I think. Since my first impressions now carry less weight, I’m more generous in my assessments of people, and way more likely to chat with someone I don’t know well. Teenage me would be baffled by how many more sources of joy and delight you can find if you just give things a chance to grow on you. Sometimes all it takes is a second try.

NOTE TO SELFMIND-BODY INTERACTIONS

So what if Nike’s neuro shoes are a placebo?

Listen to this article

Nike has just released its first ever range of ‘mind-altering’ shoes. Its glitzy marketing campaign features a chief science officer, brain scan results and dramatic music. The shoes, which have an array of bobbles (sorry, ‘nodes’) on their soles, promise to help connect your body with your brain and tune you in to the present moment. I’m sceptical about the scientific claims, but I’m impressed by the storytelling.

In medicine, it’s well known that positive expectations about an intervention, even an inert one, can produce real physiological benefits – this is the placebo effect. As the neuroscientist and placebo expert Fabrizio Benedetti explained in his paper ‘Placebos and Movies: What Do They Have in Common?’ (2021) , it is the therapeutic rituals around a placebo treatment that magnify its effects. White coats, needles, pill colours, authoritative reassurance – all these factors can trigger associations that contribute to a patient’s belief that a treatment will work.

I’m reminded of Nathan Hill’s satirical novel Wellness (2023), in which the psychologist Elizabeth starts out investigating products that make dubious claims, but comes to realise the effects are real even if they’re purely a placebo. The key to their success is the ‘story surrounding the thing’, she observes; later, she becomes a consultant for multinational corporations, helping them to craft convincing fictions.

I suspect this is exactly what Nike has done with its new range of shoes. They’ve created an elaborate, compelling narrative tailored for an athletic audience looking to gain an edge: a ‘Mind Science Department’ staffed with neuroscientists who have developed shoes that ‘disengage the default mode network’ and engage the ‘sensorimotor network of the brain’. Is any of it real? The remarkable thing about the placebo effect – and Nike’s canny marketing exploits this fully – is that it doesn’t really matter.

Even knowing that these new shoes might be relying on a placebo effect probably won’t dull any benefits. Research suggests that so-called open-label placebos – in which patients are told they are receiving a placebo – are still effective, as explained in this Psyche Idea by Darwin A Guevarra and Kari A Leibowitz. (And regardless, the Nike Mind 001 ‘pregame mules’ do look awfully comfy!)

There is a long tradition of marketing teams exploiting the allure of neuroscience to sell products. Why not wear your Nike Mind mules while sipping on a glass of NeuroSonic?

NOTE TO SELFOCD

Forever compelled

Having a history with obsessive-compulsive disorder (OCD), I’ve long found it fascinating and, in a way, reassuring to read about the disorder’s many guises. The anxious thoughts and compulsive responses to them follow a common script, but the specifics vary. What seems horrible to one person with OCD, such as using a restroom without extensively washing their hands, might seem innocuous to the next person, who’s preoccupied by something completely different (such as worrying and repeatedly testing whether doors are locked, or having ‘bad thoughts’ and scrutinising what they mean). Reflecting on this merry-go-round of fears tells you something about the true nature of your specific, seemingly terrible fear.

A book I recently read showed me another dimension of this multiplicity – stretching it backward in time. In portions of Can’t Just Stop: An Investigation of Compulsions (2017), the late science journalist Sharon Begley surveys compulsions of the past. Based on rare historical accounts, she writes, it seems that ‘until the late seventeenth century, [compulsions] were seen as evidence of Satan’s hand and addressed by clergymen.’ Some of them featured the scrupulosity that still appears in many OCD cases today – for example, compulsively praying, fearing you’ve not done it right.

But other variants emerged in the record. A Renaissance-era physician described a patient who felt compelled to wash her clothes after touching things. Later, Begley writes, changes such as the spread of household stoves encouraged compulsive checking (eg, checking and rechecking whether you left the stovetop or oven on, a well-recognised pattern today). In what sounds a lot like an OCD compulsion, the 18th-century writer Samuel Johnson would reportedly touch each lamppost as he walked down the street, ensuring he didn’t miss any. The disorder took on new faces, and the explanations for it evolved. But its insidious power appears to be age-old.

It’s a gift to share reality with someone

My partner and I say, unjokingly, that if it weren’t for dating apps we never would have met. We’re different in many ways, with divergent backgrounds, interests, musical tastes and social-media diets. While our differences meant we needed help getting together, staying together has been easy – perhaps because we have something that researchers have deemed valuable in relationships: a ‘shared reality’.

Psychology researchers define a shared reality as the perception that you share with another person many of the same feelings, attitudes and beliefs about the world. If, for example, you and a partner discuss a horror movie you’ve watched together, and it turns out that you both found particular parts scary and other bits a little silly, you’d feel a sense of shared reality about this movie. It’s the impression that the other person is seeing what you’re seeing and that you’re processing it in a similar way. This can apply to all sorts of shared experiences.

Previous research has shown that having a shared reality is related to greater relationship satisfaction and commitment. Most recently, researchers found that romantic partners who experienced a higher sense of a shared reality tended to report a greater sense of meaning in life. They also reported feeling less uncertainty when faced with stressful life and world events.

For me, it’s reassuring to have someone whose experience of the world overlaps with mine – especially in moments when I doubt my own reading of a situation. When someone’s humour at a party doesn’t sit right with me but rouses rounds of laughter, that incongruence and self-doubt can feel uncomfortable. When my partner, unprompted, later admits he didn’t enjoy it either, we both sigh in relief and talk about why. It’s a grounding process, one that confirms, time after time, that neither of us is alone in seeing things the way we do.
