case-control study
Microplastics are tiny polymer fragments that range from less than 0.2 inch to 1/25,000th of an inch. Smaller particles are called nanoplastics and are measured in billionths of a metre. Microplastics and nanoplastics (MNPs) are emerging as a potential risk factor for human health and for cardiovascular disease in particular. However, direct evidence that this risk extends to humans has so far been lacking. This investigation is a first step towards filling the gap.
The researchers conducted a prospective, multicenter, observational study involving patients who were undergoing carotid endarterectomy for asymptomatic carotid artery disease. The excised carotid plaque specimens were analyzed for the presence of MNPs with the use of pyrolysis–gas chromatography–mass spectrometry, stable isotope analysis, and electron microscopy. Inflammatory biomarkers were assessed with enzyme-linked immunosorbent assay and immunohistochemical assay. The primary end point was a composite of myocardial infarction, stroke, or death from any cause among patients who had evidence of MNPs in plaque as compared with patients with plaque that showed no evidence of MNPs.
A total of 304 patients were enrolled in the study, and 257 completed a mean (±SD) follow-up of 33.7±6.9 months. Polyethylene was detected in carotid artery plaque of 150 patients (58.4%), with a mean level of 21.7±24.5 μg per milligram of plaque; 31 patients (12.1%) also had measurable amounts of polyvinyl chloride, with a mean level of 5.2±2.4 μg per milligram of plaque. Electron microscopy revealed visible, jagged-edged foreign particles among plaque macrophages and scattered in the external debris. Radiographic examination showed that some of these particles included chlorine. Patients in whom MNPs were detected within the atheroma were at higher risk for a primary end-point event than those in whom these substances were not detected (hazard ratio, 4.53; 95% confidence interval, 2.00 to 10.27; P<0.001).
The authors concluded that, in this study, patients with carotid artery plaque in which MNPs were detected had a higher risk of a composite of myocardial infarction, stroke, or death from any cause at 34 months of follow-up than those in whom MNPs were not detected.
This is an impressive study – so much so that I report it here even though it has no connection to so-called alternative medicine, the focus of my blog. The fact that 58% of all plaques contained MNPs seems alarming. The finding that the presence of these MNPs is associated with a poor cardiovascular prognosis seems even more concerning.
MNPs have been found in every environmental compartment on earth. They are ingested not just by humans but by most animals as well. Even though research into these issues is most active, their effects are so far still under-researched and not fully understood.
The authors of the new investigation are rightly cautious: “Our data must be confirmed by other studies and on larger populations,” said Marfella, professor of internal medicine and director of the department of medical and surgical sciences at the University of Campania Luigi Vanvitelli in Naples, Italy. “However, our study convincingly highlights the presence of plastics and their association with cardiovascular events in a representative population affected by atherosclerosis.”
Of course, many questions are as yet unanswered but the subject is as worrying as it is important, e.g.:
- Should exposure to MNPs be considered a cardiovascular risk factor?
- What organs in addition to the heart may be at risk?
- How can we reduce exposure?”
I wish I knew the ansers.
Getting old is not nice – but think of the alternative!
I think it was Woody Allen who said something to that extent. But there is a third way, at least this is waht Tai Chi advocates want us to believe.
Utilizing a hybrid design, this study aimed to test whether both long-term and short-term Tai Chi (TC) training are associated with age-related decline in physical function in healthy older adults.
The authors first conducted cross-sectional comparisons among TC-naïve older adults (n = 60, 64.2 ± 7.7 years), TC-expert older adults (n = 27, 62.8 ± 7.6 years, 24.5 ± 12 years experience), and TC-naïve younger adults (n = 15, 28.7 ± 3.2 years) to inform long-term effects of TC training on physical function, including single leg stance time with eyes closed, grip strength, Timed Up and Go, maximum walking speed, functional reach, and vertical jump for lower-extremity power. There were significant differences among the three groups on all the six tests. For most functional tests, TC-experts performed better than age-matched TC-naïve controls and were statistically indistinguishable from young healthy adult controls. Long-term TC training was associated with higher levels of physical function in older adults, suggesting a potential preventative healthy aging effect.
In the randomized longitudinal trial, TC-naïve subjects were randomized (n = 31 to Tai Chi group, n = 29 to usual care control group) to evaluate the short-term effects of TC over 6 months on all outcomes. TC’s short-term impacts on physical function were small and not statistically significant. The impact of short-term training in healthy adults is less clear.
The authors concluded that both potential longer-term preventive effects and shorter-term restorative effects warrant further research with rigorous, adequately powered controlled clinical trials.
Even though the authors imply that their cross-sectional comparison points to a causal effect, this is clearly not true. For instance, it could easily be that people who are somehow destined to keep fit and agile are the ones who keep up Tai Chi. So, rather than being the result of Tai Chi, the proneness to fitness and agility could be the cause for doing Tai Chi.
The authors laudably were aware of these problems and therefore also did an RCT. Sadly this RCT did not yield significant findings. Essentially this means that eitherTai Chi did not work, or the study was naively inadequate, e.g. too small and too short-term.
Thus the authors finish with the usual statement that MORE RESEARCH IS NEEDED. This might be true, but is a definitive RCT likely?
I don’t think so.
A long time ago I had designed such a definitive study. It needed to be very large considering that many participants might drop out. Crucially, it also had to be long- term, i.e. years, not months.
And what happened to my study?
I never managed to get it funded, mainly because the costs would have been astronomical.
How often have we seen it stated on this blog and elsewhere by enthusiasts of so-called alternative medicine (SCAM) that COVID vaccinations were useless or even harmful? Here is some rather compelling evidence that should make them think again.
This population based cohort study investigated the effectiveness of primary covid-19 vaccination (first two doses and first booster dose within the recommended schedule) against post-covid-19 condition (PCC).
All adults (≥18 years) participated from the Swedish Covid-19 Investigation for Future Insights (a Population Epidemiology Approach using Register Linkage (SCIFI-PEARL) project, a register based cohort study in Sweden) with covid-19 first registered between 27 December 2020 and 9 February 2022 (n=589 722) in the two largest regions of Sweden. Individuals were followed from a first infection until death, emigration, vaccination, reinfection, a PCC diagnosis (ICD-10 diagnosis code U09.9), or end of follow-up (30 November 2022), whichever came first. Individuals who had received at least one dose of a covid-19 vaccine before infection were considered vaccinated.
The primary outcome was a clinical diagnosis of PCC. Vaccine effectiveness against PCC was estimated using Cox regressions adjusted for age, sex, comorbidities (diabetes and cardiovascular, respiratory, and psychiatric disease), number of healthcare contacts during 2019, socioeconomic factors, and dominant virus variant at time of infection.
Of 299 692 vaccinated individuals with covid-19, 1201 (0.4%) had a diagnosis of PCC during follow-up, compared with 4118 (1.4%) of 290 030 unvaccinated individuals. Covid-19 vaccination with any number of doses before infection was associated with a reduced risk of PCC (adjusted hazard ratio 0.42, 95% confidence interval 0.38 to 0.46), with a vaccine effectiveness of 58%. Of the vaccinated individuals, 21 111 received one dose only, 205 650 received two doses, and 72 931 received three or more doses. Vaccine effectiveness against PCC for one dose, two doses, and three or more doses was 21%, 59%, and 73%, respectively.
The authors concluded that the results of this study suggest a strong association between covid-19 vaccination before infection and reduced risk of receiving a diagnosis of PCC. The findings highlight the importance of primary vaccination against covid-19 to reduce the population burden of PCC.
This study should make the anti-vaxers re-consider their views. Sadly, I have little hope that they will. If they don’t, they provide rational thinkers with yet further evidence that they are cultists who are beyond learning from compelling data.
Omega-3 fatty acids (fish oil) supplementation reduces the occurrence of cardiovascular disease (CVD) and CVD-related mortality in patients at high-risk of CVD and in patients with elevated plasma triglyceride level. Yet, some studies have found an increased risk of atrial fibrillation (AF). AF is the most common sustained cardiac arrhythmia worldwide. It is associated with high morbidity and mortality rates and significant public health burden. Previous studies of the effect of omega-3 fatty acids on AF occurrence have reported contradictory results.
This review evaluated the effect of omega-3 fatty acids on the risk of AF. The results suggest that omega-3 fatty acids supplementation is associated with increased AF risk, particularly in trials that used high doses. Therefore, several factors should be considered before prescribing omega-3 fatty acids, including their dose, type, and formulation (fish, dietary fish oil supplements, and purified fatty acids), as well as patient-related factors and atrial mechanical milieu. Because the benefits of omega-3 fatty acids are dose-dependent, the associated AF risk should be balanced against the benefit for CVD. Patients who take omega-3 fatty acids, particularly at high doses, should be informed of the risk of AF and followed up for the possible development of this common and potentially hazardous arrhythmia.
Another recent review included 54,799 participants from 17 cohorts. A total of 7,720 incident cases of AF were ascertained after a median 13.3 years of follow-up. In multivariable analysis, EPA levels were not associated with incident AF, HR per interquintile range (ie, the difference between the 90th and 10th percentiles) was 1.00 (95% CI: 0.95-1.05). HRs for higher levels of DPA, DHA, and EPA+DHA, were 0.89 (95% CI: 0.83-0.95), 0.90 (95% CI: 0.85-0.96), and 0.93 (95% CI: 0.87-0.99), respectively.
The authors concluded that in vivo levels of omega-3 fatty acids including EPA, DPA, DHA, and EPA+DHA were not associated with increased risk of incident AF. Our data suggest the safety of habitual dietary intakes of omega-3 fatty acids with respect to AF risk. Coupled with the known benefits of these fatty acids in the prevention of adverse coronary events, our study suggests that current dietary guidelines recommending fish/omega-3 fatty acid consumption can be maintained.
Faced with contradictory results based on non-RCT evidence, we clearly need an RCT. Luckily such a trial has recently been published. It was an ancillary study of a 2 × 2 factorial randomized clinical trial involving 25 119 women and men aged 50 years or older without prior cardiovascular disease, cancer, or AF. Participants were recruited directly by mail between November 2011 and March 2014 from all 50 US states and were followed up until December 31, 2017.
Participants were randomized to receive EPA-DHA (460 mg/d of EPA and 380 mg/d of DHA) and vitamin D3 (2000 IU/d) (n = 6272 analyzed); EPA-DHA and placebo (n = 6270 analyzed); vitamin D3 and placebo (n = 6281 analyzed); or 2 placebos (n = 6296 analyzed). The primary outcome was incident AF confirmed by medical record review.
Among the 25 119 participants who were randomized and included in the analysis (mean age, 66.7 years; 50.8% women), 24 127 (96.1%) completed the trial. Over a median 5.3 years of treatment and follow-up, the primary end point of incident AF occurred in 900 participants (3.6% of study population). For the EPA-DHA vs placebo comparison, incident AF events occurred in 469 (3.7%) vs 431 (3.4%) participants, respectively (hazard ratio, 1.09; 95% CI, 0.96-1.24; P = .19). For the vitamin D3 vs placebo comparison, incident AF events occurred in 469 (3.7%) vs 431 (3.4%) participants, respectively (hazard ratio, 1.09; 95% CI, 0.96-1.25; P = .19). There was no evidence for interaction between the 2 study agents (P = .39).
The authors concluded that among adults aged 50 years or older, treatment with EPA-DHA or vitamin D3, compared with placebo, resulted in no significant difference in the risk of incident AF over a median follow-up of more than 5 years. The findings do not support the use of either agent for the primary prevention of incident AF.
So, does the regular supplementation with omega-3 fatty acids increase the risk of atrial fibrillation? The evidence is not entirely clear but, on balance, I conclude that the risk is low or even non-existent.
Conspiracy beliefs (CBs) can have substantial consequences on health behaviours by influencing both conventional and non-conventional medicine uptake. They can target powerful groups (i.e. upward CBs) or powerless groups (i.e. downward CBs). Considering their repercussions in oncology, it appears useful to understand how CBs are related to the intentions to use conventional and so-called alternative medicines (SCAM), defined as “medical products and practices that are not part of standard medical care” including practices
such as mind–body therapies, botanicals, energy healing or naturopathic medicine.
This paper includes two pre-registered online correlational studies on a general French population (Study 1 N = 248, recruited on social media Mage = 40.07, SDage = 14.78; 205 women, 41 men and 2 non-binaries; Study 2 N = 313, recruited on social media and Prolific, Mage = 28.91, SDage = 9.60; 154 women, 149 men and 10 non-binaries). the researchers investigated the links between generic and chemotherapy-related CBs and intentions to use conventional or SCAMs. Study 2 consisted of a conceptual replication of Study 1, considering the orientation of CBs.
Generic CBs and chemotherapy-related CBs appear strongly and positively correlated, negatively correlated with intentions to take conventional medicine and positively with intentions to take SCAM. The link between generic CBs and medication intention is fully mediated by chemotherapy-related CBs. When distinguished, upward CBs are a stronger predictor of chemotherapy-related CBs than downward CBs.
The authors concluded that the findings suggest that intentions to use medicine are strongly associated with CBs. This has several important implications for further research and practice, notably on the presence and effects of CBs on medication behaviours in cancer patients.
Sadly, the influence of CBs is not confined to the field of oncology but applies across all diseases and conditions. We have seen and discussed these issues in several previous posts, e.g.:
- Conspiracy Beliefs Predict Health Behavior and Well-being during the Pandemic
- Coronavirus conspiracy beliefs, mistrust, and compliance with government guidelines
- Mistrust + Misinformation —> CONSPIRACY THEORY
- Conspiracy theories and dangerous recommendations via YouTube videos
- Conspiracy theories, assumptions, opinions, evidence and scientific facts
- A conspiracy theory seems to be driving the popularity of alternative medicine
The most impressive evidence, however, is regularly being provided by some of the people who post comments on this blog. Collectively, this evidence has prompted me to postulate that SCAM itself can be seen as a consiracy theory.
Although bullshit is common in everyday life and has attracted attention from philosophers, its reception (critical or ingenuous) has not, to our knowledge, been subject to empirical investigation. Pseudo-profound bullshit consists of seemingly impressive assertions that are presented as true and meaningful but are actually vacuous.
In this study, researchers presented participants with bullshit statements consisting of buzzwords randomly organized into statements with syntactic structure but no discernible meaning (e.g., “Wholeness quiets infinite phenomena”). Across multiple studies, the propensity to judge bullshit statements as profound was associated with a variety of conceptually relevant variables (e.g., intuitive cognitive style, supernatural belief). Parallel associations were less evident among profundity judgments for more conventionally profound (e.g., “A wet person does not fear the rain”) or mundane (e.g., “Newborn babies require constant attention”) statements.
The authors concluded that these results support the idea that some people are more receptive to this type of bullshit and that detecting it is not merely a matter of indiscriminate skepticism but rather a discernment of deceptive vagueness in otherwise impressive sounding claims. Our results also suggest that a bias toward accepting statements as true may be an important component of pseudo-profound bullshit receptivity.
Harry G Frankfurt published his delightful booklet ‘ON BULLSHIT‘ in 2005. Since then, the term ‘bullshit’ has become accepted terminology in philosophy and science. But what exactly is bullshit? Frankfurt explains that is something between a lie and a bluff, perhaps more like the latter than the former.
In another recent article, Fugelsang explains that the growing prevalence of misleading information (i.e., bullshit) in society carries with it an increased need to understand the processes underlying many people’s susceptibility to falling for it. He also reports two studies (N = 412) examining the associations between one’s ability to detect pseudo-profound bullshit, confidence in one’s bullshit detection abilities, and the metacognitive experience of evaluating potentially misleading information.
The results suggest that people with the lowest (highest) bullshit detection performance overestimate (underestimate) their detection abilities and overplace (underplace) those abilities when compared to others. Additionally, people reported using both intuitive and reflective thinking processes when evaluating misleading information. Taken together, these results show that both highly bullshit-receptive and highly bullshit-resistant people are largely unaware of the extent to which they can detect bullshit and that traditional miserly processing explanations of receptivity to misleading information may be insufficient to fully account for these effects.
I am sure that some of the discussions on this blog are excellent examples for people with low bullshit detection performance overestimating their detection abilities and overplacing those abilities.
Many community pharmacies in Switzerland provide so-called alternative medicine (SCAM) approaches in addition to providing biomedical services, and a few pharmacies specialise in SCAM. A common perception is that SCAM providers are sceptical towards, or opposed to, vaccination.
The key objectives of this study were to examine the potential roles of biomedically oriented and SCAM-specialised pharmacists regarding vaccine counselling and to better understand the association between vaccine hesitancy and SCAM. The researchers thus conducted semistructured, qualitative interviews. Transcripts were coded and analysed using thematic analysis. Interview questions were related to:
- type of pharmaceutical care practised,
- views on SCAM and biomedicine,
- perspectives on vaccination,
- descriptions of vaccination consultations in community pharmacies,
- and views on vaccination rates.
Qualitative interviews in three language regions of Switzerland (German, French and Italian). A total of 18 pharmacists (N=11 biomedically oriented, N=7 SCAM specialised) were invited.
Pharmacist participants expressed generally positive attitudes towards vaccination. Biomedically oriented pharmacists mainly advised customers to follow official vaccination recommendations but rarely counselled vaccine-hesitant customers. SCAM-specialised pharmacists were not as enthusiastic advocates of the Swiss vaccination recommendations as the biomedically oriented pharmacists. Rather, they considered that each customer should receive individualised, nuanced vaccination advice so that customers can reach their own decisions. SCAM-specialised pharmacists described how mothers in particular preferred getting a second opinion when they felt insufficiently advised by biomedically oriented paediatricians.
The authors concluded that vaccination counselling in community pharmacies represents an additional option to customers who have unmet vaccination consultation needs and who seek reassurance from healthcare professionals (HCPs) other than physicians. By providing individualised vaccination counselling to vaccine-hesitant customers, SCAM-specialised pharmacists are likely meeting specific needs of vaccine-hesitant customers. As such, research and implementation efforts should more systematically involve pharmacists as important actors in vaccination provision. SCAM-specialised pharmacists particularly should not be neglected as they are important HCPs who counsel vaccine-hesitant customers.
I must say that I find these conclusions odd, perhaps even wrong. Here are my reasons:
- Pharmacists are well-trained healthcare professionals.
- As such, they have ethical obligations towards their customers.
- These obligations include behaving in a way that is optimal for the health of their customers and follows the rules of evidence-based practice.
- This includes explaining to vaccine-hesitant customers why the recommended vaccinations make sense and advising them to follow the official vaccination guidelines.
- SCAM-specialised pharmacist should ask themselves whether offering SCAM is in line with their ethical obligation to provide optimal care and advice to their customers.
I fear that this paper suggests that SCAM-specialised pharmacists might be a danger to the health of their customers. If that is confirmed, they should consider re-training, in my view.
Swedish researchers examined the relationship between cognitive ability and prompt COVID-19 vaccination using individual-level data on more than 700,000 individuals in Sweden.
The analyses were based on individual-level data from several administrative registers in Sweden. The study population consisted of all men and women who enlisted for military service in Sweden between 1979 and 1997. During this period, enlistment was mandatory for men the year they turned 18 or 19. Women could not enlist for military service before 1980 but were then allowed to do so on a voluntary basis.
The study population thus covered almost the entire population of Swedish men born between 1962 and 1979, in total 750,381, as well as the sample of women who enlisted during the period of 1980–1997, in total 2703. In addressing the role of confounders, the researchers analyzed the sub-sample of 6750 twin brothers (3375 twin-pairs) in the enlistment records (identified by shared biological mother and year and month of birth).
The results show a strong positive association between cognitive ability and swift vaccination, which remained even after controlling for confounding variables with a twin-design. Consistent with this, the researchers showed that simplifying the vaccination decision through pre-booked vaccination appointments alleviates almost all of the inequality in vaccination behavior.
The authors concluded that the complexity of the vaccination decision may make it difficult for individuals with lower cognitive abilities to understand the benefits of vaccination.
On this blog, we have repeatedly discussed similar or related findings, e.g.:
- What are the reasons for opposing COVID vaccinations?
- Intelligence, Religiosity, SCAM, Vaccination Hesitancy – are there links?
- COVID-19 vaccinations: Prof Walach wants to “dampen the enthusiasm by sober facts”
- Thoughts on the bigotry of vaccination opponents
- More information on homeopaths’ and anthroposophic doctors’ attitude towards vaccinations
- The ‘Trump-Effect’ on vaccination attitudes
- The anti-vaccination movement is financed by the dietary supplement industry
- Andrew Wakefield, Donald Trump, SCAM, and the anti-vaccination cult
I know, it would be politically incorrect, unkind, unhelpful, etc. but is anyone not tempted to simplify the issue by assuming that people who are against (COVID) vaccinations are intellectually challenged?
The KFF provides reliable, accurate, and non-partisan information to help inform health policy in the US. The KFF has just released its ‘Health Misinformation Tracking Poll Pilot‘ examining the public’s media use and trust in sources of health information and measuring the reach of specific false and inaccurate claims surrounding three health-related topics: COVID-19 and vaccines, reproductive health, and gun violence. It makes grimm reading indeed. Here are but a few excerpts pertaining to health/vaccination:
Health misinformation is widespread in the US with 96% of adults saying they have heard at least one of the ten items of health-related misinformation asked about in the survey. The most widespread misinformation items included in the survey were related to COVID-19 and vaccines, including that the COVID-19 vaccines have caused thousands of deaths in otherwise healthy people (65% say they have heard or read this) and that the MMR vaccines have been proven to cause autism in children (65%).
Regardless of whether they have heard or read specific items of misinformation, the survey also asked people whether they think each claim is definitely true, probably true, probably false, or definitely false. For most of the misinformation items included in the survey, between one-fifth and one-third of the public say they are “definitely” or “probably true.” The most frequently heard claims are related to COVID-19 and vaccines.
Uncertainty is high when it comes to health misinformation. While fewer than one in five adults say each of the misinformation claims examined in the survey are “definitely true,” larger shares are open to believing them, saying they are “probably true.” Many lean towards the correct answer but also express uncertainty, saying each claim is “probably false.” Fewer tend to be certain that each claim is false, with the exception of the claim that more people have died from the COVID-19 vaccines than from the virus itself, which nearly half the public (47%) recognizes as definitely false.
Across the five COVID-19 and vaccine related misinformation items, adults without a college degree are more likely than college graduates to say these claims are definitely or probably true. Notably, Black adults are at least ten percentage points more likely than White adults to believe some items of vaccine misinformation, including that the COVID-19 vaccines have caused thousands of sudden deaths in otherwise healthy people, and that the MMR vaccines have been proven to cause autism in children. Black (29%) and Hispanic (24%) adults are both more likely than White adults (17%) to say that the false claim that “more people have died from the COVID-19 vaccine than have died from the COVID-19 virus” is definitely or probably true. Those who identify as Republicans or lean towards the Republican Party and pure independents stand out as being more likely than Democratic leaning adults to say each of these items is probably or definitely true. Across community types, rural residents are more likely than their urban and suburban counterparts to say that some false claims related to COVID vaccines are probably or definitely true, including that the vaccines have been proven to cause infertility and that more people have died from the vaccine than from the virus.
Educational attainment appears to play a particularly important role when it comes to susceptibility to COVID-19 and vaccine misinformation. Six in ten adults with college degrees say none of the five false COVID-19 and vaccine claims are probably or definitely true, compared to less than four in ten adults without a degree. Concerningly, about one in five rural residents (19%), adults with a high school education or less (18%), Black adults (18%), Republicans (20%), and independents (18%) say four or five of the false COVID-19 and vaccine misinformation items included in the survey are probably or definitely true.

I do encourage you to read the full article.
This study aimed to clarify the psychological mechanism by which individuals accept health misinformation from social media and how health misperceptions affect subsequent unhealthy behavior in the context of dewormer use.
An online survey was conducted with 307 South Korean adults exposed to dewormer use information on social media. The positive association between the respondents’ uncertainty about their health and factual misbeliefs about dewormer use was moderated by their pre-existing attitude toward so-called alternative medicine (SCAM) vs. standard treatments, suggesting that individuals who are uncertain but more favorable toward SCAM tend to accept factual misbeliefs more easily. Individuals’ uncertainty about their health and treatment for the health management was positively associated with conspiracy beliefs. Factual misbeliefs were the key mediator in the association between the interaction of uncertainty and pre-existing attitude toward SCAM vs. standard treatments and dewormer-taking intention.
This is a subject that we have discussed many times before. See, for instance, here:
- How can we reduce the belief in conspiracy theories?
- Conspiracy Beliefs Predict Health Behavior and Well-being during the Pandemic
- Coronavirus conspiracy beliefs, mistrust, and compliance with government guidelines
- Mistrust + Misinformation —> CONSPIRACY THEORY
- Conspiracy theories and dangerous recommendations via YouTube videos
- “The cancer industry is a medical conspiracy against humanity” (The Turmeric story)
- Conspiracy theories, assumptions, opinions, evidence and scientific facts
- A conspiracy theory seems to be driving the popularity of alternative medicine
In my view, it is hugely important. Consumers who are uncertain, easily misled, convinced that ‘the establishment’ is against them, or prone to other conspiracy theories tend to be the ones that also fall easily for the lies of SCAM promoters. Indeed, I have previously suggested that SCAM itself is a conspiracy theory in disguise. Anyone who has been following the comment sections on this blog will find more evidence for this theory than he had ever needed, I fear.
It is clear to me that misinformation undermines not just evidence-based medicine but – much more dangerous -rationality in general. It would be thus urgent to do something about it.
But what?
In my view, the answer is to promote critical thinking. This, of course, is what I am aiming at with my blog. But my effort is merely a drop in the ocean. What we need is a systematic promotion of critial thinking on a much larger scale. It has to start at school and should be followed through to post-graduate education and beyond.
Such a strategy would require a very broad backing, not least on the political levels. And this is where the concept runs into insurmountable difficulties: politcians might not want us to be critical thinkers! This could enable the public to realize what often dismally poor jobs they might be up to.
