Bruce Hood is professor of developmental psychology in society at the University of Bristol in the UK. He’s also the author of ‘The Science of Happiness: Seven Lessons for Living Well’ (2024). In this insightful long essay, he explains why a lunchtime course he offered to the stressed out students at the prestigious university not only made those students 10-15% happier (survey data apparently pointed to this improvement in several cohorts of students), but also gave Prof Hood an insight into why Positive Psychological Interventions or PPIs (eg. maintaining a daily journal, doing group-based tasks, meditation) could make the rest of us happier.

Prof Hood’s hypothesis regarding the drivers of unhappiness and the path to happiness is fascinating for non-psychologists like us who don’t their yin from their yang: “Infants start off with an egocentric view of the world – a term and concept introduced by the psychologist Jean Piaget. Egocentric individuals tend to perceive the world from their own perspective, and many studies have shown that young children are egocentric in the way they see the world, act, talk, think and behave with others. Normal development requires adopting a more allocentric – or other-based perspective in order to be accepted. The sense of self changes from early ebullient egocentrism to an increasing awareness of one’s relative position in the social order. Children may become more other-focused but that also includes unfavourable comparisons. They increasingly become self-aware and concerned about what others think about them – a concern that transitions into a preoccupation when they enter adolescence that never really goes away. As for adults, like many features of the human mind, earlier ways of thinking are never entirely abandoned. This is why our self-focus can become a ‘curse’, as the psychologist Mark Leary describes, feeding the inner critic who is constantly negatively evaluating our position in life.

One reason that self-focus can become a curse is that we are ignorant of the biases our brains operate with that lead us to make wrong decisions and comparisons. When it comes to happy choices, we want something because we think it will make us happy, but our predictions are inaccurate. We think events will be more impactful than they turn out to be, and we fail to appreciate how fast we get used to things, both good and bad. This is called a failure of affective forecasting which is why the psychologist Dan Gilbert explains that our tendency to ‘stumble on happiness’ is because our emotional predictions are so way off. We don’t take into consideration how future circumstances will differ because we focus on just one element and we also forget how quickly we adapt to even the most pleasurable experiences. But the most pernicious aspect of self-focus is the tendency to keep comparing ourselves to others who seem to be leading happier lives. Social media is full of images of delicious plates of food, celebrity friends, exotic holidays, luxurious products, amazing parties and just about anything that qualifies as worthy of posting to bolster one’s status…”

Prof Hood then goes on to explain that PPI seems to work by mitigating the damaging impact of our own ego on our brain: “If egocentric self-focus is problematic then maybe positive psychology works by altering our perspective to one that is more allocentric or ‘other-focused’? To do so is challenging because it is not easy to step out of ourselves under normal circumstances. Our stream of conscious awareness is from the first-person, or egocentric, perspective and, indeed, it is nigh-on-impossible to imagine an alternative version because our sensory systems, thought processes and representation of our selves are coded as such to enable us to interact within the world as coherent entities.

Many PPIs such as sharing, acts of kindness, gratitude letters or volunteering are clearly directed towards enriching the lives of others, but how can we explain the benefits of solitary practices where the self seems to be the focus of attention? The explanation lies with the self-representation circuitry in the brain known as the default mode network (DMN). One of the surprising discoveries from the early days of brain imaging is that, when we are not task-focused, rather than becoming inactive, the brain’s DMN goes into overdrive. Mind-wandering is commonly reported during bouts of DMN activity and, although that may be associated with positive daydreaming, we are also ruminating about unresolved problems that continue to concern us….

If you focus on your problems, this can become difficult to control. There’s no point trying to stop yourself ruminating because the very act of trying not to think about a problem increases the likelihood that this becomes the very thought that occupies your mind. This was first described in an 1863 essay by Fyodor Dostoyevsky, when he observed the effect of trying not to think; he wrote: ‘Try to pose for yourself this task: not to think of a polar bear, and you will see that the cursed thing will come to mind every minute.’ My late colleague Dan Wegner would go on to study this phenomenon called ironic thought suppression, which he explained resulted from two mechanisms: the tendency to increase the strength of the representation of a thought by the act of trying to suppress it, and a corresponding increased vigilance to monitor when the thought comes to the fore in consciousness. Ironic thought suppression is one reason why it can be so difficult to fall asleep. This is why one of our recommended activities on our Science of Happiness course is to journal on a regular basis because this helps to process information in a much more controlled and objective way, rather than succumbing to the torment of automatic thinking….

Other recommended activities that calibrate the level of self-focus also attenuate DMN activity. For example, mindfulness meditation advocates not trying to suppress spontaneous thoughts but rather deliberately turning attention to bodily sensations or external sounds. In this way, the spotlight of attention is directed away from the internal dialogue one is having with oneself….This is why achieving absorption or full immersion during optimal states of flow draws conscious awareness and attention out of egocentric preoccupation. To achieve states of flow, we recommend that students engage in activities that require a challenge that exceeds their skill level to an extent that they rise to the task, but do not feel overwhelmed by it. When individuals achieve flow states, their sense of self, and indeed time itself, appears to evaporate.

There are other more controversial ways to alter the egocentric self into one that is more allocentric….”
