Human-Kind. Isn’t that lovely. We have moved away from the patriarchal term mankind – ‘man’ who has not always been ‘kind’, necessarily – toward equality between the sexes and acknowledging gender fluidity. Noah touches on this. If you’re interested in the evolution of humanity and how we are capable of co-operating as a global community, give this book a go. You may experience information overload – but when condensing 2.4 million years into less than 500 pages, Harari goes alright. I’m someone who didn’t pay attention to history at school so I found this book enlightening, empowering and also disheartening at times. Harari writes about the breakthroughs of the Cognitive, Agricultural and Scientific Revolutions. The power of human imagination, math and language has been instrumental in the development of humankind into an apex predator, and the destruction of everything else.

Problematic Thinking Styles (continued)Problematic Thinking Styles (continued)
Hello readers! A few of the cognitive styles below were mentioned in my last post. As humans, we have a tendency to forget things so a bit of revision can be useful.
Many people have cognitive processes that result in overall unhelpful thinking styles that they tend to apply globally across situations and which may result in emotional distress (such as depression or anxiety) or unhelpful behaviours (such as anger or avoidance). Some of the most problematic thinking styles are listed in the extract below.
Mental Filter: This thinking styles involves a “filtering in” and “filtering out” process – a sort of “tunnel vision”, focusing on only one part of a situation and ignoring the rest. Usually this means looking at the negative parts of a situation and forgetting the positive parts, and the whole picture is coloured by what may be a single negative detail.
Jumping to Conclusions: I’m sure you’ve heard people say on television, “Don’t jump to conclusions” or “The truth is we just don’t know yet”. We jump to conclusions when we assume that we know what someone else is thinking (mind reading) and when we make predictions about what is going to happen in the future (predictive thinking).
Personalisation: This involves blaming yourself for everything that goes wrong or could go wrong, even when you may only be partly responsible or not responsible at all. You might be taking 100% responsibility for the occurrence of external events.
Catastrophising: Catastrophising occurs when we “blow things out of proportion” and we view the situation as terrible, awful, dreadful, and horrible, even though the reality is that the problem itself is quite small. A helpful restructuring of this cognition is to ask yourself if the situation will still be awful, terrible, or dreadful in a month. There may be ongoing consequences or stress involved if you lose a job or a relationship ends, so validate the experience you are having but also take a look at the big picture. What’s the worst that could happen? Why is the worst so “bad”? And if you are being realistic about the issue, reach out for some help if you can.
Black & White Thinking: This thinking style involves seeing only one extreme or the other. You are either wrong or right, good or bad and so on. There are no in-betweens or shades of grey.
Should-ing and Must-ing: Sometimes by saying “I should…” or “I must…” you can put unreasonable demands or pressure on yourself and others. Although these statements are not always unhelpful (e.g. “I should not get drunk and drive home”), they can sometimes create unrealistic expectations.
Overgeneralisation: When we overgeneralise, we take one instance in the past or present, and impose it on all current or future situations. If we say “You always…” or “Everyone…”, or “I never…” then we are probably overgeneralising.
Labelling: We label ourselves and others when we make global statements based on behaviour in specific situations. We might use this label even though there are many more examples that aren’t consistent with that label.
Emotional Reasoning: This thinking style involves basing your view of situations or yourself on the way you are feeling. For example, the only evidence that something bad is going to happen is that you feel like something bad is going to happen. I live with anxiety and it can be debilitating at times. I use my “wiser thinking” or “rational thinking” to evaluate whether I am operating from an emotional mindset. You might ask yourself: “What’s the evidence?”, “Does the past necessarily predict the future?”, “Am I angry or fearful right now because that might be clouding my judgement?”. It can be helpful to talk to someone who isn’t caught in your emotional headspace, or perhaps wait for the emotion to subside to think about the situation again.
Magnification and Minimisation: In this thinking style, you magnify the positive attributes of other people and minimise your own positive attributes. It’s as though you’re explaining away your own positive characteristics.

Dr Rangan Chatterjee chats with Dr Gabor Maté about his radical findings based on decades of work with patients. We’re currently living in a culture that doesn’t meet our human needs. Maté and Chatterjee delve into how our emotional stress can translate into physical chronic illnesses, and how loneliness and a lack of meaningful connection are on the rise, as are the rates of autoimmune disease and addiction.
Understanding Addiction: A Modern, Integrative PerspectiveUnderstanding Addiction: A Modern, Integrative Perspective
Abstract
Addiction is a complex, multifaceted phenomenon that has been described variously as a disease, disorder, syndrome, obsessive-compulsive behaviour, learned behaviour, or spiritual malady. Modern scientific understanding emphasises addiction as a chronic brain disorder shaped by neurobiological changes, learning, and social context. This article examines each conceptualisation and presents an integrated definition that aligns with current neuroscience, psychological, and public health evidence.
Conceptualising Addiction: Labels and Their Accuracy
No single label fully captures addiction’s complexity; each highlights certain truths while overlooking others.
Disease
From a medical perspective, disease is the closest match. Addiction involves persistent neurobiological changes in reward, stress, and self-control circuits, increases relapse risk over years, and shows substantial genetic vulnerability (~50–60%) (NIDA, 2018; Heilig et al., 2021). Treatments improve outcomes but rarely “cure” the condition. This framing is used by the American Society of Addiction Medicine (ASAM), NIDA, WHO ICD-11, and DSM-5-TR (as “Substance Use Disorder”) (NIDA, 2018).
Disorder
Disorder is also scientifically accurate and slightly less medicalised. DSM-5’s “Substance Use Disorder” captures behavioural, psychological, and biological criteria and recognises functioning and harm rather than framing addiction strictly as a lifelong disease (Heather, n.d.; Heilig et al., 2021).
Syndrome
Addiction may be described as a syndrome because it is a cluster of symptoms with behavioural and physiological manifestations, without a single causative factor. However, the term is too generic for practical use outside clinical texts (Blithikioti et al., 2025).
Obsessive and Compulsive Learned Behaviour
Addiction involves learning, habit formation, and compulsion through reinforcement of rewarding behaviours (Hyman, 2005; Hausotter, 2013). Yet describing it solely as learned behaviour ignores genetic predisposition, neuroadaptation, withdrawal, and social factors.
Spiritual Malady
Some mutual-aid traditions characterise addiction as a spiritual malady. While this may be meaningful for individuals, it is not scientifically explanatory: addiction can be adequately explained via biological, psychological, and social mechanisms (Lewis, 2017).
Modern Integrative Definition
The most accurate contemporary description of addiction is:
“A chronic, relapsing disorder of brain circuits involved in reward, stress, and self-control, shaped by learning, environment, and social context”.
This definition encompasses:
- Disease/disorder: medical accuracy
- Learned behaviour and compulsion: neuroscience and behavioural accuracy
- Social determinants: public health relevance
- Flexibility for personal or spiritual interpretations
In short, addiction is best understood as a bio-psycho-social condition that is treatable and sometimes reversible, rather than a deterministic, lifelong curse.
Neurobiology: Why Addiction Is Considered a Brain Disorder
Repeated substance use alters structural and functional brain circuits involved in reward, stress, motivation, memory, and self-control (Nwonu et al., 2022; NIDA, 2018). These changes can persist long after use stops, explaining why addiction is more than a matter of “bad habits” or weak will (NIDA, 2025).
Chronicity and Relapse
Addiction is often chronic and relapsing. Even after long periods of abstinence, cues and stressors can trigger relapse (Meurk et al., 2014; SAMHSA, 2023). Key regions implicated include the basal ganglia (habit formation), extended amygdala (stress), and prefrontal cortex (decision-making) (Kirby et al., 2024). Nevertheless, many individuals achieve stable remission, highlighting heterogeneity in clinical outcomes (Heilig et al., 2021).
Learning, Memory, and Habit Formation
Addiction exploits neural mechanisms of learning and memory: rewarding behaviours are repeated and consolidated into habits, with cues triggering compulsive responses even when the substance’s reward diminishes (Hausotter, 2013; Lewis, 2017). This intertwines biological disorder and learned behaviour.
Critiques and Limitations
Some scientists caution that framing addiction strictly as a brain disease is simplistic:
- Brain changes may resemble those from other motivated behaviours (Lewis, 2017).
- Many recover without formal treatment (Heilig et al., 2021).
- Social, environmental, and psychological factors are crucial to understanding addiction (Blithikioti et al., 2025).
Thus, while the disease model is powerful, it does not fully represent addiction’s heterogeneity or socio-psychological dimensions.
Implications for Treatment
Addiction is treatable, not simply curable. Interventions combining pharmacological and behavioural approaches, alongside social support, can foster long-term recovery (Liu & Li, 2018; Heilig et al., 2021). Like other chronic conditions, management — rather than elimination — is often the realistic goal (NIDA, 2018). Neural circuits can gradually readjust, particularly when environmental and personal factors support recovery.
Conclusion
Addiction is a learned, compulsive brain disorder with chronic potential, shaped by neurobiological, psychological, social, and environmental factors. Recognising addiction as both a disorder and a behavioural learning condition avoids extremes: it is neither an unchangeable fate nor merely a moral failing. This integrated perspective supports nuanced understanding, compassionate care, and effective treatment strategies.
