Trump’s appearance at the rescheduled White House Correspondents’ Dinner yesterday rapidly descended into a public unravelling. Rather than using the occasion to project confidence, humour and presidential composure, he transformed it into a rambling assault on the press, political opponents and even the organisers of the event. What should have been an evening of wit and satire became yet another illustration of his primitivity and increasingly erratic behaviour.

Perhaps the most revealing aspect of Trump’s performance was not its length but its tone. The Correspondents’ Dinner traditionally rewards self-deprecating humour, demonstrating that a president possesses enough confidence to laugh at himself. Rejecting that convention entirely, Trump resorted to personal insults, inelegant mockery and familiar grievances, singling out journalists including Kaitlan Collins, Anderson Cooper and Don Lemon.

When one of his remarkably crude jokes failed to resonate, he neither recovered gracefully nor moved on. Instead, he blamed his speechwriters, dismissed his prepared remarks as “frickin’ stupid”, and publicly distanced himself from his own performance. Rather than displaying resilience, he exposed an inability to cope with even mild social failure.

In my view, Trump’s behaviour is psychologically revealing. It reflects a personality style characterised by grandiosity, a profound need for admiration, low tolerance of frustration and hypersensitivity to criticism. Individuals with pronounced narcissistic traits often externalise failure, shifting blame to others rather than accepting responsibility themselves. Trump’s spontaneous denunciation of his own script was a textbook example of this defensive manoeuvre. Rather than adapting to an audience that was not responding as hoped, he converted an awkward moment into yet another occasion of victimhood and betrayal.

Equally striking was Trump’s inability to modulate his behaviour to suit the occasion. Intelligent political leaders recognise the demands of different settings and adjust their tone accordingly. Yet, Trump appeared unable to distinguish between a campaign rally and an event designed around humour and mutual tolerance between politicians and journalists. His persistent return to personal grievances shows not merely poor political judgement but impaired behavioural flexibility.

From a medical perspective, the performance also raises questions about executive functioning. Executive functions are the cognitive processes responsible for planning, inhibiting inappropriate responses, adapting to changing circumstances and regulating emotions. Throughout the speech, Trump abandoned prepared material, drifted into tangential attacks, failed to recognise when jokes were unsuccessful, and did to recover from minor setbacks.

Of course, none of these observations proves neurological pathology, and no diagnosis can responsibly be made from a public appearance alone. Nevertheless, together with uncounted similar events, they are behaviours compatible with diminished executive control and reduced cognitive flexibility.

I fear that the evening confirmed a now all too familiar combination of narcissistic defensiveness, impulsivity and poor emotional regulation. The performance showed strikingly poor judgement, limited adaptability and an inability to restrain impulses. For a man in Trump’s position, that was probably the most revealing aspect of the evening. My concern is not that his poor joke fell flat; politicians survive this sort of thing all the time. My concern is that, when confronted with even a trivial setback, Trump is incapable of responding adequately.

Personally, I would be less concerned about the future of the world, if Americans would finally realise what is happening and get this man out of the White House.

“Popularity takes the place of plausibility, tradition replaces validity, and individual experience is positioned above objective efficacy.”

This sentence (my translaation of the German original) comes from a book by Udo Endruscheit that I have been reading. It is entitled “Vom Zweifel zur Haltung: Eine Reise durch die Geschichte der Erkenntnis” (From Doubt to Conviction: A Journey Through the History of Knowledge) and outlines the epistemological development of truth from the early thinkers of antiquity to the postmodern voices of today. It traces how the concept of truth has changed, how it has been criticized, relativized, and deconstructed, and how these changes have shaped us and our thinking.

The statement was no necessarily meant to me applied to medicine, but it does aply capture a recurring epistemological pattern within large segments of so-called alternative medicine (SCAM). It describes a shift away from the truth towards criteria that are socially and psychologically compelling but scientifically nonsensical.

The substitution of popularity for plausibility is evident in the way many SCAMs have gained traction. Treatments such as homeopathy, naturopathic detox regimens, or paranormal energy-based healing have achieved global followings despite the fact that there can hardly be a mechanism of action that does not fly in the face of science. Their popularity is often driven by anecdotal endorsements, celebrity advocacy, and market forces rather than by convergence of experimental and theoretical support. Opinion counts more than truth, and the absence of plausibility in a SCAM is frequent and frequently ignored.

The elevation of tradition over validity is a defining feature of most SCAMs. Historical longevity is often presented as implicit evidence of effectiveness. “It would not have survived, if it were ineffective!” Yet, from a scientific perspective, tradition is a most unreliable indicator: ineffective or even harmful practices can persist for centuries in the absence of effectiveness and even safety. Bloodletting in pre-modern Western medicine offers a cautionary example. The critical issue is not whether a therapy is old, but whether it has been subjected to rigorous evaluation and shown to produce reproducible benefits that exceed placebo and other non-specific effects.

The dominance of individual experience over objective effectiveness is perhaps the most pervasive and psychologically persuasive cause of SCAM’s popularity. Patients’ testimonials, often sincere and seemingly compelling, are being touted as sufficient evidence of effectiveness. Yet individual experience is highly susceptible to regression to the mean, natural disease fluctuation, placebo effects, confirmation and other biases and confounders. Without proper comparisons, it is impossible to distinguish specific therapeutic effects from non-specific ones. Evidence-based medicine does not dismiss patient experience; rather, it contextualizes it with external evidence to avoid misleading us all.

The above statement by Udo Endruscheit was meant as a general characterisation of the way we currently handle and mishandle truth. As such it applies to much more than just SCAM. Yet, it also provides an apt critique of dominant tendencies within SCAM. Popularity, tradition, and personal experience are, of course, not inherently without value, but when they displace plausibility, validity, and objective effectiveness, they create a situation that is wide open to error, exploitation and often also harm.

In a nutshell: the truth matters; watering it down – as we all currently tend to do – carries serious risks in medicine as much as in life.

 

PS

I almost forgot!

Yes, I do recommend reading Udo’s most fascinating book.

Because homeopathic remedies are usually diluted to the point where none of the original substance remains (often beyond Avogadro’s number), the ethical concerns with this treatment must focus on veracity (truth-telling), patient autonomy, beneficence, and justice. Here are some of the problems that ensue**:

Violations of Veracity and Informed Consent

Informed consent is an essential element of medical ethics and dictates that a patient must be given full, accurate, and evidence-based information regarding a treatment’s nature, mechanisms, risks, and efficacy to make an autonomous decision.

Homeopathy operates on two main principles: “like cures like” (Law of Similars) and the “law of minimum dose” (the more diluted a substance, the more potent it becomes). Scientifically, these principles contradict established kowledge of chemistry, physics, and pharmacology. Presenting these concepts nevertheless as scientifically valid violates veracity.

When a practitioner administers or sells a homeopathic remedy without explicitly stating that it contains no active ingredients and performs no better than a placebo in clinical trials, the patient’s autonomy is compromised. In other words, patients are making a healthcare choice based on deception or omission.

Maleficence 

While homeopathics are physically inert and thus unlikely to cause direct harm, homeopathy poses a severe threat via indirect harm.

The most critical ethical issue occurs when patients use homeopathy for severe, progressive, or life-threatening conditions (such as cancer, severe infections, or chronic diseases like diabetes). Delaying or entirely replacing evidence-based medicine with placebo treatments (i.e. homeopathy) violates the duty of non-maleficence (do no harm). It can lead to preventable suffering, worsening of the condition, or even death in extreme cases.

Homeopathic “Vaccines” (Homeoprophylaxis) is an apt example. Some homeopaths offer all sorts of homeopathic vaccinations as alternatives to standard immunizations. Marketing these as effective protection against potentially deadly diseases like measles, polio, or pertussis erodes public herd immunity, leaves individuals entirely unprotected, and can endanger us all. This is a massive failure of both individual and public health ethics.

Beneficence

Beneficence requires healthcare providers to act in the best interest of the patient by offering treatments that provide a tangible, therapeutic benefit.

While the empathetic, unhurried nature of a homeopathic consultation can provide psychological comfort, homeopaths cannot ethically justify charging high fees for what is essentially a placebo wrapped in pseudo-medicine. Relying on a mechanism that depends on the patient remaining ignorant of the treatment’s true nature is fundamentally paternalistic and violates modern standards of beneficence.

Justice and the Exploitation of Vulnerability

The ethical principle of justice involves fairness, equity, and the responsible distribution of healthcare resources. It is regularly violated in the realm of homeopathy.

Homeopathic remedies are cheap to manufacture, yet they are marketed at unjustifiably inflated prices. Targeting vulnerable populations, such as the chronically ill, parents anxious about medication side effects in their children, or low-income individuals seeking cheap alternatives, is an ethical violation of justice.

When public the health insurance programs of certain countries, or mainstream pharmacies fund or promote homeopathic products alongside effective medicines, they misallocate resources and mislead the public. In other words, they give a false stamp of authority to quackery, draining resources that could support evidence-based public health initiatives.

So, how unethical is homeopathy? My short answer is: VERY!

** for a more detailed discussion, please have a look at our book.

I was reminded of a paper that I published a long time ago – 23 years to be precise. It is entitled THE LECTURE FROM HELL.  As it is not available online, let me give you a slightly revised version of it here:

When it comes to giving lectures, I have certainly made every mistake there is, and therefore I consider myself qualified to write this personal account on how to deliver THE LECTURE FROM HELL. I do this in the hope that others might learn from my imperfections.

In preparing for a lecture, it is best to be cool and leave things to the last minute. You are so gifted and competent that a few scribbles made on the way to the venue will easily suffice for fascinating your audience. Don’t bother enquiring who they are; what you have to say will capture the attention of a lay audience as much as that of a highly specialised one.

The kind people who have invited you will certainly have suggested a topic. Don’t get irritated by that; you know best what you can and want to talk about and, after all, it is always best to stick to what you know. If your subject is palliative cancer care, for instance, it should not be too difficult, after a few introductory sentences, to shift the attention to the most revealing survey you conducted on 10 back pain patients 25 years ago – cancer patients suffer from back pain too!

From the outset, you need to show the audience that you are better than they are. A good way of achieving this aim is to display your knowledge of as many acronyms as possible. Making abundant use of abbreviations has the added advantage that it could hide a few glitches in your arguments (or spelling). People might even think you are talking about palliative care after all.

Another golden rule is never produce evidence for your statements. Some people use visual aids to produce the evidence, but this is both tiring and confusing (and it would, of course, require much more preparation than you allowed for). If you want to use visual aids, use photographs of your kids (pets if you are childless) or your last holiday in Corfu. This will add the personal touch that people crave. Surely, if they had wanted evidence they would have gone to a library, not to your lecture.

It is advisable to spend as much time as possible with lengthy preliminaries, particularly if you are not really covering the subject as printed in the programme. Mention that you first met Cathy (who just introduced you) when you were both in nursery and give a full and colourful account of your relationship since then. If you haven’t actually been to nursery with Cathy, perhaps you could talk about the car accident you saw en route and what it made you think of. Or you could take the holistic approach, ask everyone to stand up, do a few relaxation exercises and feel the flow of energy in the body, room or universe. The obvious aim is to leave as little time as possible for the proper lecture. Thus, you can pretend to know much more about your subject than you had time to disclose and you can end your unfinished lecture with the upbeat exclamation ‘‘yeah! perhaps another time’’.

Most lecturers find the ensuing discussion period the most challenging part of their task. Not you! First, you have wisely ensured that there is no time left. Thus, the discussion slot will either be completely cancelled or it will be refreshingly brief. When the first difficult question comes your way, remember the important principle: you are so much cleverer than anyone else in this room! Make sure you show it. Arrogance has always been a perfect shield for hiding incompetence.

Another good strategy is to ridicule the person who dared ask the awkward question. Thus, they end up with egg on their face instead of you. If all else fails and you really don’t know how to answer, the best approach is to say: ‘‘this is a bit too complex right now; perhaps I could explain this to you later over coffee’’. Just ensure that you are safely on the way home when the coffee break starts.

Generally speaking, the overriding principles of a truly diabolically bad talk are quite simple. Lectures are neither the time nor place for transmitting knowledge to those who came to listen. Their predominant purpose is to massage the lecturer’s ego and increase their income. If you keep this in mind, you will stop worrying about things like evidence, structure and delivery and simply enjoy the outing.

I was reminded of this article because I saw the title of a recently published paper: HOW TO GIVE A BAD TALK. It starts as follows: “It is crucial to know how to communicate your work by delivering an effective talk, but our training for doing so is limited, so it is a skill often learned by watching others — who sometimes do it badly”.

Sadly, I could not read on; the journal asked almost 30 Euros for the privilege! So, I will never know what else I can do to give a truly poor lecture. Yet, I did learn something important: the knowledge of how to give a bad talk does not always come cheap!

I recently coined a new term: Chutzpah-Based Medicine (CBM). It requires a bit of an explanation which I herewith try to deliver. Medical decisions should rely on a rational hierarchy: systematic reviews at the top, followed by randomised clinical trials, observational studies, and way down at the bottom we anecdotal experience and opinion. The new paradigm of “Chutzpah-Based Medicine” (CBM) turns this pyramid upside down.

In CBM, double-blind trials are replaced by double-down charisma. Why wait 10 years for evidence when you can assert a medical breakthrough in 15 seconds on video with dynamic lighting, an unbuttoned linen shirt, and absolute, unshakable certainty? Here is an overview of the core tenets and leading luminaries of this revolutionary field.

The Dogmas of CBM

  • The Confidence-to-Evidence Ratio: The validity of any health claim is directly proportional to the volume, velocity, and eye contact with which it is delivered.
  • The “Big Pharma Secret” Axiom: If a treatment worked and had evidence, it would evidently be mainstream. Therefore, the total absence of evidence is the ultimate proof that “They” are trying to suppress it.
  • Quantum Syllogism: If you insert the word “quantum” before anything, biology no longer applies, and anything becomes possible.

Four Ambassadors of CBM

  1. Gwyneth Paltrow

The undisputed pioneer of High-End CBM. Paltrow proved that with enough aesthetic minimalism and raw audacity, one can sell jade eggs, vaginal steaming, and “psychic vampire repellent” as essential wellness routines. Scientific consensus is but a sign of unrefined taste. See also previous posts, e.g.:

  1. Dr. Mehmet Oz

Before entering politics, Dr. Oz laid the groundwork for CBM. He demonstrated that a cardiothoracic surgeon could look directly into a camera and declare green coffee bean extract a “miracle burn in a bottle” without blinking. “Magic” is, according to Oz, a valid clinical outcome. See also previous posts, e.g.:

  1. Dr. Joseph Mercola

He is a true titan of digital CBM mastering the art of building a multi-million-dollar supplement empire by warning millions that modern medicine is a toxic conspiracy, while conveniently offering his own unapproved tanners, liposomal vitamins, and other SCAMs as the sole salvation. See also previous posts, e.g.:

  1. Deepak Chopra

Chopra brought profound philosophical chutzpah to CBM by blending endocrinology with poetic quantum bollox. By asserting that human bodies are “localized energy fields” capable of “quantum healing,” he elevated clinical vagueness into a high-margin spiritual enterprise. See also previous posts, e.g.:

While Evidence-Based Medicine requires years of arduous testing, CBM offers immediate answers, simple villains, and premium-priced remedies. Why let a clinical trial get in the way of an excellent means of getting rich quickly?

Exercise is recommended for managing pain, yet the consistency, magnitude, and certainty of effects across different pain conditions and exercises remain unclear. This umbrella review aimed to synthesize the best available evidence on the analgesic effects of exercise by examining systematic reviews and meta-analyses of randomized controlled trials (RCTs).
Eleven databases were systematically searched from inception to August 2024. Eligible studies included systematic reviews with meta-analyses of RCTs comparing exercise to control conditions, with pain as a primary or secondary outcome. Reviews without meta-analyses, those not involving RCTs, or those primarily focused on experimentally induced or laboratory pain were excluded. Two reviewers independently extracted data and assessed methodological quality using AMSTAR-2. Standardized mean differences in pain were synthesized using random-effects meta-meta-analysis. Certainty of evidence was evaluated using GRADE, with subgroup and sensitivity analyses.
A total of 157 systematic reviews comprising 2,736 RCTs and 221,279 participants were included. Exercise significantly reduced pain compared with controls (pooled standardized mean differences = −0.59; 95% CI, −0.65 to −0.53; P < 0.001). Effects were observed across both chronic and acute pain conditions, encompassing musculoskeletal, neurological, inflammatory, and cancer populations. Aerobic, resistance, yoga, Pilates, and tai chi were effective. Greater effects were observed in lower-intensity, shorter-duration (<12 weeks) programs. Sensitivity analyses supported the robustness of findings, and the overall GRADE certainty was moderate.
The authors concluded that this umbrella review provides robust evidence supporting the effectiveness of exercise for managing a wide range of pain conditions. Our findings suggest that relatively brief, low-intensity programs, often perceived as more achievable by people living with chronic pain, are associated with greater pain reductions on average. However, these patterns reflect trends across diverse studies and should not be interpreted as prescriptive. Rather, they underscore the importance of starting with accessible, lower-dose programs that can be adjusted based on individual needs, preferences, and progression. Given the consistent benefits observed across exercise types and populations, clinicians are encouraged to integrate exercise as a core component of multimodal pain care. These findings reinforce the role of exercise as a safe, adaptable, and patient-centred option, particularly valuable in addressing the limitations of pharmacological pain management. Future research should focus on how to best individualise, deliver, and sustain effective exercise interventions in real-world clinical settings..
This is an excellent paper that provides a wealth of data relevant to both clinicians and patients. The authors report that significant, large reductions in pain were observed for various modes of exercise, including aerobic, aquatic, dance, HIIT, mind body (various), mixed-mode, Pilates, resistance, tai chi, telehealth, exergames and VR, and yoga. The largest reduction in pain was observed for dance, Pilates, and tai chi. It occurs to me that these three forms of exercise are normally all performed in groups and thus have a strong sociaal element to them. Could it be that this is an additional factor in their analgesic benefit?
While these exercises seem particularly effective, the most remarkable finding is, in my view, that practically ALL types of excercise work for practically ALL types of pain. This means, I think, that it might be best to let the patient decide which type of excercise he or she prefers; this might be one way to increase compliance. Because compliance might in many cases a significant problem. If you have severe pain, you are not usually motivated to do excercise!

I spent the last 2 months in France where it happened to be hot. Too hot for my taste! I could not do much during the day and, at night, I was unable to sleep well. As the heatwave carried on, it began to impact on my mood and health. I may be particularly sensitive to heat, but I am by no means the only one who suffered. Record-breaking temperatures and unprecedented ocean warming have triggered a global health emergency. Driven by climate change, modern heatwaves are predicted to strike with greater frequency, intensity, and duration, pushing human physiology to (and sometimes past) its limits.

Extreme heat operates as a silent killer by severely exacerbating pre-existing cardiovascular and respiratory conditions. It can also cause acute medical issues like severe dehydration, kidney damage, heatstroke, and even death. Extreme heat disproportionately impacts highly vulnerable groups, including older adults, children, outdoor laborers, and individuals who are unhealthy to start with. Urban populations face magnified dangers due to the urban heat island effect, which traps dense pockets of heat in city environments.

The consequences are already devastating. The recent heatwaves in Europe caused over 1,300 excess deaths within just a few weeks. Extreme heat contributes to a global toll of hundreds of thousands of heat-related fatalities each year. It also ripples through societal infrastructure. Extreme heat heavily strains our healthcare systems, disrupts local economies, worsens food and water insecurity worldwide, endangers local transport and other infrastructure. Here in France, for instance, we had prolonged cuts first of electricity and then on the Internet/telephone; many people and shops had to throw away the content of their fridges and freezers. Even more alarming: one of France’s largest rivers, the Loire, went completely dry.Image result for loire dried up

An analysis of nearly 2,500 UK media articles covering the June heatwave found that most reports failed to connect the event to climate change, despite strong scientific evidence that global heating intensifies extreme weather. Approximately three-quarters of the articles made no reference to climate change or global warming, highlighting a significant gap between scientific consensus and public communication. Such omissions are problematic because they leave audiences without crucial context. Attribution science now allows researchers to quantify how much more likely or intense specific heatwaves have become due to greenhouse gas emissions, primarily from fossil fuel use. Without this information, heatwaves may be perceived as isolated or purely natural events rather than manifestations of a broader, human-driven trend. Failing to link extreme weather to climate change undermines public understanding and may weaken support for mitigation and adaptation policies.

The most worrying thing is that we are rapidly approaching irreversible thresholds. To mitigate this mounting catastrophe, immediate international cooperation is required. We must deploy both short-term adaptation strategies, such as robust local heat action plans and early warning weather networks, as well as aggressive, long-term global emissions reductions. And we also should vote out politicians who still:

  • pretend that climate change is a hoax,
  • blame their neighouring country, despite being huge polluters themselves,
  • shout “drill baby, drill”,
  • pretend that summers have always been hot,
  • claim (against all medical knowledge) that humans will somehow manage to adapt to extreme heat.

Without urgent measures, the human and economic toll will escalate uncontrollably.

The Medical Journalists’ Association (MJA) has outlined six practical tips to help scrutinise health claims responsibly and accurately. They are primarily meant for journalists but, I think, they are also usefull for the general public, particularly when dealing with health claims in the realm of so-called alternative medicine (SCAM):

Check the source
Assess whether the claim originates from credible, peer-reviewed research and a reputable institution. Be wary of press releases, anecdotal reports, or media outlets known for sensationalism. Specifically for claims about SCAM, we might also add caution regarding the many third class SCAM journals.

Look for conflicts of interest
Investigate who funded the research and whether any authors or organisations stand to profit from the findings. Industry sponsorship can introduce bias, even in otherwise well-conducted studies. For claims about SCAM, we should remember that financial interest might be secondary to ideological ones.

Examine the study design
Consider whether the research used appropriate methods – such as randomisation, control groups, and adequate sample sizes – to support its conclusions. Observational studies, or case reports, or trials with the often-discussed ‘A+B versus B’ design, for example, cannot prove causation.

Consider the magnitude and relevance of effects
Distinguish between statistical significance and clinical importance. A tiny effect may be statistically significant in a large trial but meaningless in practice. Also ask whether the study population is representative and the outcome can be generalised.

Look for independent replication
Single studies should be treated cautiously until confirmed by other researchers. Consistent findings across multiple studies increase confidence in a claim.

Beware of over-interpretations
Scrutinise whether the authors or media coverage extrapolate beyond what the data support. For instance, generalising from animal studies to humans, or implying benefits without evidence of improved health outcomes.

___________________

If I may, I will add an 7th to the six by the MJA. It is one that I have issued many times previously and that is, I think, essential in SCAM:

If it sounds too good to be true, it probably is!

Exaggerated or false health claims are endemic in SCAM. These 7 tips might be useful in disclosing them and in minimising the harm they can do.

Medical ethics rests on 4 core principles: autonomy, beneficence, non-maleficence, and justice, along with the crucial rule of veracity (truth-telling). In the realm of chiropractic, the most significant ethical issues/problems generally fall into the following ethical categories:

  1. Compromised Informed Consent & Veracity

Informed consent requires that a patient fully understands the nature, risks, benefits, and scientific backing of a treatment before proceeding.

1.1.The “Subluxation” Theory: A sizable segment of the chiropractic community still adheres to the erroneous belief that spinal “vertebral subluxations” cause a disruption in the body’s “innate intelligence,” leading to systemic disease. From an ethical standpoint, promoting an unproven, pseudo-scientific premise as medical fact violates veracity and compromises patient autonomy, as patients cannot give truly informed consent based on erroneous concepts.

1.2. Over-claiming Scope of Efficacy: While evidence might support spinal manipulation for acute lower back pain (if one were to interpret the dtat optimistically), most chiropractors claim they can treat many other illnesses, including non-musculoskeletal conditions such as asthma, allergies, infantile colic, ADHD, and high blood pressure. Marketing these services without robust clinical trial backing misleads vulnerable populations.

  1. Violations of Non-Maleficence

The principle of non-maleficence requires practitioners to avoid inflicting unnecessary harm or exposing patients to disproportionate risks.

2.1. Cervical Manipulation and Stroke Risk: One of the most severe ethical concerns involves high-velocity, low-amplitude (HVLA) thrusts to the upper neck, the hallmark modality of chiropractors. This procedure has been linked to vertebral artery dissection (VAD), which can cause strokes and deaths. The ethical failure is most obvious when chiropractors perform these adjustments without warning the patient of this and other adverse outcomes.

2.2. Paediatric Chiropractic: Performing spinal adjustments on infants and toddlers (whose spines are primarily cartilage and still developing) poses distinct physical risks. Because infants cannot consent and the evidence of benefit for childhood ailments is practically non-existent, this behaviour violates non-maleficence.

  1. Secondary Harm: Delay of Standard Medical Care

Harm does not only come from physical injury; it also comes from omitting or delaying necessary medical treatment.

3.1. Anti-Vaccine and Anti-Medicine Sentiments: A large proportion of the chiropractic profession advise patients against conventional medicine, pharmaceuticals, and vaccination. When a chiropractor discourages a patient from seeking standard medical care, they are actively contributing to potentially life-threatening delays in care.

  1. Violations of Beneficence and Justice

Beneficence means acting in the patient’s best interest, while justice involves the fair and equitable distribution of healthcare resources.

4.1. The “Maintenance Care” Business Model: A common predatory practice of chiropractors involves convincing patients that they require lifelong, regular spinal adjustments to “stay aligned” and prevent disease, often locked into expensive upfront contracts. Recommending continuous, costly treatments that lack clinical evidence of long-term benefit shifts the focus from patient welfare (beneficence) to practitioner financial gain.

4.2.Over-Utilization of X-rays: Some chiropractic clinics mandate full-spine X-rays for every new patient, regardless of symptoms, and repeat them frequently to “prove” alignment changes. Exposing patients to unnecessary ionizing radiation for marketing or diagnostic justification is a direct violation of both non-maleficence and the ethical use of healthcare resources.

For a more detailed account of the ethical problems in so-called alternative medicine, please see our book on this very subject.

Religiosity has been linked to a wide range of health outcomes, with evidence for both benefits and harms.

Alleged positive effects

Many studies have found positive associations between religious involvement and physical and mental health, including lower mortality, better self-rated health and greater psychological well‑being. However, most of this literature is methodologically weak, with selection bias, poor control for confounders and selective reporting, so firm causal conclusions are difficult.

Religiosity and spirituality have frequently been associated with positive effects on mental health, such as higher levels of life satisfaction, meaning in life, hope, optimism and lower rates of depression, substance misuse and some forms of suicidal behaviour. Proposed mechanisms include social support from religious communities, promotion of coping resources, encouragement of health‑promoting behaviours and cognitive frameworks that help some people make sense of adversity.

In addition, observational studies have linked religious participation with positive effects on physical endpoints, such as reduced smoking, more moderate alcohol use and in some cases better cardiovascular outcomes and lower all‑cause mortality, though effect sizes are usually modest. Cross‑national analyses show that religious people sometimes report better self‑rated health, but these associations vary widely by country and are sensitive to socioeconomic and cultural context.onlinelibrary.

Alleged negative effects

Some aspects of religiosity might be harmful: religious struggles—such as feeling punished by God, spiritual discontent or conflict with religious communities—are consistently associated with higher levels of depression, anxiety and distress. Some studies also suggest that rigid or punitive religious beliefs can exacerbate guilt, internalized stigma (for example around sexuality) and delay help‑seeking for mental illness.

In highly secular societies, belonging to a religious minority may correlate with poorer health, possibly via discrimination, lower social integration or economic disadvantage. A critical economic analysis even reports a negative relationship between religious background and some health indicators once socioeconomic factors are carefully controlled, challenging simple “religion is good for you” narratives.

Methodological problems

Much of the evidence relies on observational studies, making it difficult to be sure about causality: healthier or more socially integrated people may be more likely to be religiously active. Measures of religiosity and spirituality are heterogeneous, ranging from attendance to private practices to diffuse “spiritual well‑being”, which complicates comparisons and may inflate positive findings. In other words, the effects of religiosity on health are less that certain or clear.
