Lost Connections: Why You’re Depressed and How to Find Hope

By Johann Hari

This book explores depression by examining its underlying causes and arguing that it is often the result of a complex combination of factors rather than a single biological problem. Johann Hari pieces together the many parts of the puzzle, suggesting that depression cannot always be understood or treated through medication alone.

The book questions the widespread use of antidepressants as the primary treatment for depression, proposing that the causes are often far more complex than medicine alone can address.

Hari also questions the evidence supporting the theory that depression is caused by a chemical imbalance. He discusses the work of Harvard professor Irving Kirsch, who examined research into antidepressants and concluded that many antidepressants were no more effective at reducing depression than placebos given in place of the medication.

Questioning the biological chemical imbalance theory of depression, Hari explores nine major causes that appear to be linked to depression—factors that often lie beyond the reach of medication alone.

Disconnection from Meaningful Work

Hari examines how a lack of meaningful work can contribute to depression. While unemployment and illness can clearly play a role in some cases, he also highlights how a lack of purpose, fulfilment, and motivation in the workplace can negatively affect mental wellbeing.

“Twice as many people hate their jobs than love their jobs”.

“This thing that 80% of us don’t enjoy is spreading into more of our lives”.

Disconnection from Other People

Hari explores the importance of social connection by discussing the research of John Cacioppo. Cacioppo studied individuals’ feelings of loneliness while measuring cortisol (stress hormone) levels and heart rate.

He concluded:

‘Being deeply lonely, in his research felt as stressful as a physical attack’.

Disconnection from Meaningful Values

This chapter focuses on cultural attitudes in the Western world while also examining research on baboons. The studies looked at which members of the social group experienced the highest levels of stress hormones, drawing comparisons with human society. It was noted that depressed humans are flooded with the same stress hormones.

Hari also discusses the work of Paul Gilbert, who suggested that depression may, in part, be a submission response.

Childhood Trauma

The book examines the ACE (Adverse Childhood Experiences) Study, which showed a close correlation between childhood trauma and later mental health outcomes.

“If you had experienced six categories of traumatic events in childhood you are five times more likely as an adult to suffer from depression.
If you had had seven of the categories as a child of 3100% more likely to attempt to commit suicide as an adult.

Disconnection from the Natural World

Hari explores how psychological distress appears to be higher in urban environments. He discusses research suggesting that people who moved to greener areas experienced lower levels of psychological distress.

Disconnection from Status

Hari examines research involving primates, where stress hormone levels were measured across different positions within the social hierarchy. Stress levels were found to be highest among those at the bottom of the hierarchy, but were also elevated at the very top, where competition and the constant risk of losing status remained high.

Disconnection from a Secure and Hopeful Future

In a later chapter, Hari considers how a lack of control over one’s future can influence mental health.

He writes:

‘Indigenous populations who have a lack of control over the higher power above has a big impact on mental health.
The tribal communities with the highest control have the lowest suicide rates.
The tribal communities with the lowest control have the highest suicide rates’.

Social Prescribing

Hari concludes by exploring how social prescribing can be an effective way of addressing depression. Rather than focusing solely on medication, social prescribing aims to rebuild the connections and address the forms of disconnection and trauma described throughout the book.

My Conclusion

In essence, I believe Johann Hari is encouraging us to look beyond the idea that depression is solely a biological illness. Although lower serotonin levels have been observed in people with depression, the question remains whether this is the cause or the result of the condition. It is similar to asking which came first—the chicken or the egg. Could lower serotonin levels be an effect of depression rather than its primary cause?

The book broadens our understanding of depression by highlighting the importance of factors such as power, status, feeling valued, feeling safe, being loved, feeling alive, having meaningful social contact, and living with purpose. Our ability to find meaning in our lives and maintain hope can make a profound difference and help us to thrive once again.
