I am attending quite a few webinars these days to see what I can learn.
Note: this is about right now. This is not to say that I applaud this government and its approach, not at all.
The UK government has lied a lot in the past ten years and also often sucks at communicating well. That is causing some problems now, I noticed on Twitter.
“There are 12,000 ventilators” followed by “8,000 within the NHS” does not by definition mean that the government is lying but may mean that its communication skills are not up to par.
It could mean:
- 4,000 on the way to the NHS;
- 4,000 within the Navy, Army, Air Force, private facilities and also some on the way to the NHS;
Something similar is going on with COVID-19 tests and reagents. It is very hard to find info in the UK as it is a low-transparency country. (I for example found detailed information about a local water treatment facility (Budd’s Farm) in the Netherlands some years ago, but was unable to find much about it in the UK.)
I looked into it, found some info on the CDC site, spotted the name Roche, and remembered something I had read in the Dutch news. The Netherlands is much more transparent than the UK, so I looked into that angle.
It may also be helpful to keep in mind that the Netherlands is a highly egalitarian country. A lot of the wheeling and dealing that goes on in the UK would not be permitted in the Netherlands. (I am not saying that none goes on there.)
Roche makes a lot of the equipment needed for the tests and that equipment requires certain chemicals to run. Roche also manufactures the required lysis buffer and was briefly not able to keep up with global demand.
It initially was not willing to share the secret “recipe” either. It did later release it after all, but it is actually not that easy to make so it cannot simply be made by anyone and has to involve certification of the labs who make the stuff. Roche currently is able to keep up with demand again, so I understand.
In addition, the Dutch health minister, too, mentioned shortages in other test-related materials on 27 March.
(The UK government specifically mentioned a shortage of swabs.)

I am assuming that the UK is using the same test as the Netherlands or a very similar test (which is also likely the same as the US is using). (I have a report – collection of international information – from a Belgian university in my pc that probably has details on that; I will see what it says and add that info later.)
Conclusion: The UK government for once appears to be NOT LYING.
The information given by the UK government appears to match the information available in the Netherlands.
(The – possibly inadvertent – spin in the UK currently appears to be coming from… Labour?, I say tentatively, on the basis of the tweets that I saw.)
(As I have posted some tweets from Tory MPs in the past, I should also do it with tweets from other MPs. I have no idea what was said during Newsnight)
From the “living paper” report in my pc (“Overview of information available to support the development of medical countermeasures and interventions against COVID-19” by Martine Denis, Valerie Vandeweerd, Diane Van der Vliet, version 23 March 2020):
A list of assays commercially available for diagnosis of COVID-19 is updated by FIND (https://www.finddx.org/covid-19/). Assays that are still in development stage are also presented.”
The report has a lot more information on testing, but does not state details on which country is using which tests and protocols. If you click on the above link, however, you’ll find a lot of information that indicates that Covid-19 testing requires rigid procedures to be able to work. In other words, ramping up capacity is likely not as simple as some MPs think it is.
(For comparison: You wouldn’t want a sloppy pregnancy test that is often wrong either.)
Here we see how a young woman’s mental health crisis got her into handcuffs and in front of a judge for having inconvenienced the public.
Police criminalized this woman. That’s how stigmas work.
Now compare that situation with that of, say, a pregnant woman whose waters break in the middle of a supermarket? Or hey, who cramps while driving a car on the way to the hospital, skids, spins and ends up blocking traffic?
If police did not discriminate, the latter woman should be handcuffed and dragged in front of a judge as well.
Would police do that?
And what would police do with a woman who ends up in a diabetic crisis while travelling on public transport?
Or with anyone daring to have a heart attack in public?
Today, I watched a few videos on YouTube about women in poverty, many of whom are homeless or illegally living in a caravan, particularly if they are pensioners. They may get a small pension, but it’s not enough to live on AND rent a place.
They live in the US, Australia, or New Zealand. (I already know quite a bit about the situation in the UK, where one third of the people live in poverty.) They are 48, 57 or 69 years old.
From reading newspapers, I get the impression that poverty is very slowly starting to creep up in the Netherlands too now. That is where I am from, a country where most people still have incomes with lifestyles that now come across as obscene to me, but that I used to see as normal.
There is not necessarily anything wrong with it – apart from the resource consumption that can be linked to it – but I call it obscene because of the giant contrast with the lives I see around me.
To give a comparison that they may be able to understand, their lives are like having gold taps and gold handles throughout the house and expensive champagne with smoked salmon and caviare at breakfast every day.
What strikes me particularly about the stories of the women in the videos is that they never expected to live in poverty and are totally gobsmacked by the fact that they are.
But here is the thing. It’s not them. They didn’t necessarily do anything wrong. It’s mostly the result of sheer coincidence.
Several of them mentioned the 2008 financial crisis. (Thank you, banks.) Others mentioned a divorce, hence suddenly being without a home.
They grew up in a time when life was still good. For most of them, it was a reasonable expectation that they would not be poor a few decades later.
It’s made me remember that in 2006 or thereabouts, various articles more or less predicted this rise in poverty, this sharpening division in the haves and have-nots. There was a lot of talk about corn, and the price of it. The articles said that we were heading for a time of food insecurity and a lot of poverty. It worried me. It sounded alarming. It made me look into emigrating to countries with much lower living expenses and the kind of climate in which I thrive.
If you thrive, physically, you can do more work. If you live in pleasant surroundings and don’t struggle with paying the bills, you maintain better health, too. All of these factors help.
I seem to recall that those articles also said that knowledge workers would increasingly get into difficulties, but that the opportunities for creatives would likely become much better. Back then, I had no idea what that meant in practice. (Maybe the people who wrote those articles did not know either.) It is starting to dawn on me now.
Once you’re in real poverty, it’s almost impossible to get out of, it seems, unless you have an extraordinary stroke of luck, for most people.
There have to be ways to solve this, stop this from progressing. Yo, creatives, can you come up with some bright ideas?
The focus of the world is shifting. The articles predicted that too. It’s true. The United States no longer run the world.
Some of the women in the YouTube videos solved their homelessness by taking up house-sitting, although that also sometimes meant that they were no longer eligible for social housing. One of the women has MS, the relapsing-remitting version, and no health insurance.
Something else struck me, too. These women were too nice about it all, too accepting, taking their worries and bouts of depression in stride.
“You’ve got to roll with the punches.”
True, but rolling with the punches means that the punches barely touch you and don’t hurt you. When the punches hurt and you never asked for them, never started the fight yourself, you’re entitled to a bit of anger. There are power and energy in certain kinds of anger – but women are still not supposed to get angry.
The above is the title of the 2018 Petrie-Flom Center Annual Conference, which took place in June. I had registered for the event because the topic interests me greatly and I have so much to learn in this area. Unfortunately, I turned out to be away and unable to attend after all.
I am delighted that the Petrie-Flom Center not only decided to make some of the lecture materials available beforehand, but recorded the lectures and has made the videos shareable.
Prominent point of discussion at he conference was the question whether a disability is merely a difference, or a bad difference. Putting the question like this is an oversimplification but it is a good starting point. I will discuss this matter and these lectures in greater detail in coming posts.
For now, here are the opening remarks, and first talks.
As a psychiatrist, I find that one of the hardest parts of my job is telling parents and their children that they are not to blame for their illness.
Children with emotional and behavioral problems continue to suffer considerable stigma. Many in the medical community refer to them as “diagnostic and therapeutic orphans.” Unfortunately, for many, access to high-quality mental health care remains elusive.
An accurate diagnosis is the best way to tell whether or not someone will respond well to treatment, though that can be far more complicated than it sounds.
I have written three textbooks about using medication in children and adolescents with emotional and behavioral problems. I know that this is never a decision to take lightly.
But there’s reason for hope. While not medically able to diagnose any psychiatric condition, dramatic advances in brain imaging, genetics and other technologies are helping us objectively identify mental illness.
Knowing the signs of sadness
All of us experience occasional sadness and anxiety, but persistent problems may be a sign of a deeper issue. Ongoing issues with sleeping, eating, weight, school and pathologic self-doubt may be signs of depression, anxiety or obsessive-compulsive disorder.
Separating out normal behavior from problematic behavior can be challenging. Emotional and behavior problems can also vary with age. For example, depression in pre-adolescent children occurs equally in boys and girls. During adolescence, however, depression rates increase much more dramatically in girls than in boys.
It can be very hard for people to accept that they – or their family member – are not to blame for their mental illness. That’s partly because there are no current objective markers of psychiatric illness, making it difficult to pin down. Imagine diagnosing and treating cancer based on history alone. Inconceivable! But that is exactly what mental health professionals do every day. This can make it harder for parents and their children to accept that they don’t have control over the situation.
Most important of all is making sure your child is assessed by a licensed mental health professional experienced in diagnosing and treating children. This is particularly important when medications that affect the child’s brain are being considered.
Seeing the problem
Thanks to recent developments in genetics, neuroimaging and the science of mental health, it’s becoming easier to characterize patients. New technologies may also make it easier to predict who is more likely to respond to a particular treatment or experience side effects from medication.
Our laboratory has used brain MRI studies to help unlock the underlying anatomy, chemistry and physiology underlying OCD. This repetitive, ritualistic illness – while sometimes used among laypeople to describe someone who is uptight – is actually a serious and often devastating behavioral illness that can paralyze children and their families.
Through sophisticated, high-field brain imaging techniques – such as fMRI and magnetic resonance spectroscopy – that have become available recently, we can actually measure the child brain to see malfunctioning areas.
We have found, for example, that children 8 to 19 years old with OCD never get the “all clear signal” from a part of the brain called the anterior cingulate cortex. This signal is essential to feeling safe and secure. That’s why, for example, people with OCD may continue checking that the door is locked or repeatedly wash their hands. They have striking brain abnormalities that appear to normalize with effective treatment.
We have also begun a pilot study with a pair of identical twins. One has OCD and the other does not. We found brain abnormalities in the affected twin, but not in the unaffected twin. Further study is clearly warranted, but the results fit the pattern we have found in larger studies of children with OCD before and after treatment as compared to children without OCD.
Meanwhile, the field of psychiatry continues to grow. For example, new techniques may soon be able to identify children at increased genetic risk for psychiatric illnesses such as bipolar disorder and schizophrenia.
New, more sophisticated brain imaging and genetics technology actually allows doctors and scientists to see what is going on in a child’s brain and genes. For example, by using MRI, our laboratory discovered that the brain chemical glutamate, which serves as the brain’s “light switch,” plays a critical role in childhood OCD.
What a scan means
When I show families their child’s MRI brain scans, they often tell me they are relieved and reassured to “be able to see it.”
Children with mental illness continue to face enormous stigma. Often when they are hospitalized, families are frightened that others may find out. They may hesitate to let schools, employers or coaches know about a child’s mental illness. They often fear that other parents will not want to let their children spend too much time with a child who has been labeled mentally ill. Terms like “psycho” or “going mental” remain part of our everyday language.
The example I like to give is epilepsy. Epilepsy once had all the stigma that mental illness today has. In the Middle Ages, one was considered to be possessed by the devil. Then, more advanced thinking said that people with epilepsy were crazy. Who else would shake all over their body or urinate and defecate on themselves but a crazy person? Many patients with epilepsy were locked in lunatic asylums.
Then in 1924, psychiatrist Hans Berger discovered something called the electroencephalogram (EEG). This showed that epilepsy was caused by electrical abnormalities in the brain. The specific location of these abnormalities dictated not only the diagnosis but the appropriate treatment.
That is the goal of modern biological psychiatry: to unlock the mysteries of the brain’s chemistry, physiology and structure. This can help better diagnose and precisely treat childhood onset mental illness. Knowledge heals, informs and defeats ignorance and stigma every time.
Large health inequalities exist in Australia. Car ownership and its costs add to the health inequalities between low-income and high-income households. The physical characteristics of neighbourhoods influence our transport use and, in turn, make health inequalities better or worse.
Rising housing prices have forced many low-income families to live on the fringes of Australian capital cities. Residents of these sprawling outer suburbs often have worse access to public transport, employment, shops and services. They need one or more motor vehicles simply to get to work and take children to school.
Buying and maintaining vehicles in Australia is expensive. These costs have a large impact on household budgets. Household finances then affect health in two main ways:
- through the ability to access health-related resources, such as healthy foods, health care and high-quality living conditions (like heating and cooling)
- through stress caused by financial difficulties, insecure incomes and exposure to poorer environments such as crowding, crime and noise pollution.
Living in the car-dependent urban fringes also often dooms residents to long sedentary commutes.
Four scenarios of transport costs
The following four hypothetical households demonstrate the costs of varying levels of car ownership and transport behaviours.
Scenario 1: A household with two cars that are 15,000km and 10,000km, respectively, per year. The car that is driven 15,000km is assumed to be less than three years old, bought new and financed with a loan. The other car is assumed to be 10 years old and owned outright. This household aligns with estimates by the Australian Automobile Association.
Scenario 2: Scenario one, minus the used car and substituting five return public transport trips a week to the Melbourne central business district from the outer suburbs.
Scenario 3: No cars, substituting 10 return trips to the CBD from the outer suburbs.
Scenario 4: No cars, substituting three return trips to the CBD (i.e. occasional public transport use), with walking and cycling as the main forms of transport.
Table 1 shows how reducing household car ownership, even after adding the cost of public transport, can improve household finances.
Moving from a two-car household to a one-car household cuts weekly costs by as much as A$41, even after increased public transport use adds a A$41-a-week cost.
Moving from a two-car household to having no cars can improve weekly finances by as much as A$237, after adding 10 return trips to the CBD.
The fourth scenario, emphasising walking and cycling, shows the greatest improvement in household finances. These families are $294 per week better off.
The impacts on households of each of these car ownership and transport scenarios differ depending on their incomes. To illustrate this, we’ve taken the median disposable household income from the lowest, middle and highest quintiles from the ABS in 2015-16.
Although becoming car-free will increase disposable household income after paying for transport, the largest proportional differences are for the lowest-income households. This means these households will benefit most from reducing car ownership and switching to more active and affordable forms of transport.
Urban design can boost household health and wealth
So how do we help households make the transition from private car ownership? The answer lies in the environments we live in.
The evidence from research suggests several strategies to improve uptake of active and affordable transport, while reducing car dependence and related health inequities. These include local urban design features such as:
- connected and safe street networks (including pedestrian and bicycle infrastructure) that reduce exposure to traffic
- residential areas mixed with commercial, public service and recreational opportunities
- public transport that is convenient, affordable, frequent, safe and comfortable
- higher residential density with different types of housing (including affordable housing) to support the viability of local businesses and high-frequency public transport services
- cycling education and promotion
- car-free pedestrian zones, traffic calming measures, signage and accessibility for all (including wheelchair and pram access).
Australia has yet to fully realise the potential of promoting active transport and reducing car dependency as a way to reduce health inequities.
For example, the Victorian government recently announced 17 new low-density suburbs for Melbourne’s outer fringes (up to 50 kilometres from the CBD). It did so with a goal of creating more affordable housing. But urban planning experts have criticised these plans for increasing car dependence and commute times – due to the lack of nearby destinations and amenities – which have been shown to be bad for health.
In another case, the Planning Institute of Australia described the proposed A$5.5 billion West Gate Tunnel as a “retrograde solution”. The institute expressed concern about “entrenched inequality for those in the outer suburbs”.
Changes to city transport environments can take years or even decades, and funding is often limited. Phased interventions that target lower-income neighbourhoods should be considered first as these are likely to produce the greatest gains in health equity.
This approach does have some caveats. Urban renewal projects carry a risk of gentrification, whereby higher and middle-income households displace those on lower incomes. Place-based government investment, such as improvements to public transport, has been shown to increase local housing prices. That could force lower-income households to relocate, often to car-dependent neighbourhoods on the urban fringes.
In these scenarios, a lack of government policies that safeguard against displacement of low-income residents can make health inequities worse.

Tuna is one of the most ubiquitous seafoods. It can be eaten from a can or as high-end sashimi and in many forms in between. But some species are over-fished and some fishing methods are unsustainable. How do you know which type of tuna you’re eating?
Some tuna is certified as sustainably caught by groups such as the Marine Stewardship Council (MSC) that set standards for sustainable fishing. But these certifications are only good if they are credible.
In late August, several media outlets published stories about On the Hook, a new campaign by a consortium of retailers and academics who have taken issue with some fishing practices allowed by the MSC. As a university professor whose research focuses on private seafood governance, including certifications and traceability, and fisheries policy, I am deeply familiar with the issues at hand. I support the campaign, but don’t stand to gain from the outcome.
The Western and Central Pacific skipjack tuna fishery is one of the world’s biggest. Some of the tuna caught here carries the MSC’s blue label, identifying it as the best environmental choice for consumers. But the same boats making that sustainable catch may also use unsustainable methods to catch unsustainable fish on the same day.
The On the Hook coalition sees this as at odds with the MSC certification, as do I. Yes, sustainable and unsustainable fish can be separated; there are people on board whose sole job is to do this. But rewarding fishermen for their sustainable catch, while allowing them to fish unsustainably, dupes consumers into supporting companies that take part in bad behaviour.
Does sorting work?
The On the Hook campaign singles out one fishery in particular: the “purse seine” fishery in the tropical western Pacific Ocean. This fishery covers the waters of eight island nations, including Micronesia, the Marshall Islands, Papua New Guinea and the Solomon Islands. Under the Nauru Agreement, these nations, usually referred to as the Parties to the Nauru Agreement (PNA), collectively control access to about one quarter of the world’s tuna supply.
Fishermen can use nets to catch free-swimming adult tuna and earn MSC certification for their catch. But these same fishermen can also use fish aggregating devices (FADs) — instruments that attract all kinds of marine life, including adult tuna, juvenile tuna and hundreds of species of sharks, turtles and other fish — to net their catch. Fishing on FADs is faster and less costly, but these devices are associated with high levels of bycatch, one of the main sustainability concerns in many fisheries. Fishing on FDAs does not earn MSC certification.
Under normal operations, the fishermen use both methods. “Compartmentalization” is a technique that allows the unsustainable portion of the fish to be separated on board the vessel from the sustainable portion. This is supposed to provide assurance to consumers that they are making a sustainable choice. Yet the negative environmental impacts connected to FAD fishing operations should surely also be considered in an MSC assessment. Currently, this does not happen.
Compartmentalization remains necessary because there isn’t enough of an economic advantage for companies to make only sustainable catches. It costs fishermen more to fish sustainably because they have to find the tuna, instead of waiting for it to come to the FAD.
A fleet using both methods can be part of a higher value premium market and earn financial security from the high volume, yet unsustainable, fishery. If purse-seining tuna vessels need to subsidize their sustainable fishing with unsustainable practices, then MSC certification has not provided the incentive it set out to.
A holistic fishery
Millions of tonnes of tuna have been fished from the waters of the Western and Central Pacific fishery. But the countries controlling these waters have not benefited to a large extent, mostly due to a lack of cooperation in bargaining for benefits, which allowed distant nations to exploit the fishery.
In the past decade, these Pacific Island states have increased their bargaining power in regional negotiations by implementing a scheme that controls the number of boats that can enter their waters. Under the program, called the vessel day scheme (VDS), these countries can now charge higher fees to boats that want access.
For example, PNA countries used to extract between three per cent and six per cent of the value of tuna fishery in their waters. Since their bargaining power has increased, they can now extract more than 14 per cent of the value, and this number is likely to continue to rise.
This is no small accomplishment for these Pacific Island nations, and other coastal state collectives are now trying to emulate their success. But this does not mean that all of the practices they allow are commendable, including those that are not representative of the “best environmental choice” in seafood.
On my Facebook feed, a colleague recently commented: “A Pacific Islander owned sustainably certified fishery is the wrong target.”
Let me clear up this misconception. The On the Hook campaign is not targeting the PNA, but the MSC. It would like the MSC to delay the recertification — authorized by the accreditation body in September — of the PNA fishery until the compartmentalization practice has been addressed. The fishery needs to be considered holistically.
For example, the MSC could specify that to earn a certification, a boat cannot fish sustainably and unsustainably on the same fishing trip. Consumer dollars should not be supporting the very practices the MSC condemns.
Another colleague remarked that because the PNA is challenging big industry, the On the Hook campaign might benefit big industry and hurt the PNA. In fact, it is the same boats, the same fleet, the same companies that are fishing MSC-certified tuna and on FADs.
My colleagues also worry that the campaign calls into question the credibility of the MSC label. But this has actually become commonplace, with many groups pointing at examples of certified fisheries that are not sustainable. For example, the WWF has recommended that seafood buyers should stay away from MSC-certified Mexican tuna.
I would argue that the MSC is tarnishing itself by normalizing the practice of compartmentalization. It is no longer clear that fish carrying the MSC label offer the best environmental choice. Many Canadian fisheries, like lobster, herring, and Atlantic redfish, are MSC-certified. The faltering credibility of the MSC is a major risk for Canadian fish harvesters who rely on the MSC label to communicate their good fishing practices.
Additionally, Canadian consumers who are used to searching for the blue MSC check mark when they shop for seafood can no longer do so thinking that the logo conveys accurate information. Consumers need to know that the waters are muddy, that seafood sustainability is a moving target, and that it is not easy to make the right choice when standing in the aisle at the supermarket.
Governments and businesses need to make that choice easier for consumers. And they could start by dealing with compartmentalization in the PNA fishery — and elsewhere.
The PNA countries could also make demands. They could allow access rights only to vessels that agree to drop the practice of compartmentalization and that are transparent about their fishing practices.
More than anything, the MSC needs to take a good look at itself and remember what it is supposed to represent — the best environmental choice — not consumer confusion.
Not only is it more sustainable – which I checked with sustainable fisheries expert Edd Hind a few years back – canned / tinned mackerel has all the healthy fish oils. Tuna in cans or tins does not.
The High Court has rejected a judicial review challenging the current law which prohibits assisted dying in the UK. Noel Conway, a 67-year-old retired lecturer who was diagnosed with Motor Neurone Disease in 2014, was fighting for the right to have medical assistance to bring about his death. Commenting after the judgement on October 5, his solicitor indicated that permission will now be sought to take the case to the appeal courts.
Campaigners are often quick to highlight the strength of public support in favour of assisted dying, arguing that the current law is undemocratic. But there are reasons to question the results of polls on this sensitive and emotional issue.
There have been numerous surveys and opinion polls on public attitudes towards assisted dying in recent years. The British Social Attitudes (BSA) Survey, which has asked this question sequentially since the 1980s, has shown slowly increasing public support. Asked: “Suppose a person has a painful incurable disease. Do you think that doctors should be allowed by law to end the patient’s life, if the patient requests it?” in 1984, 75% of people surveyed agreed. By 1989, 79% of people agreed with the statement, and in 1994 it had gone up to 82%.
Detail of the question matters
But not surprisingly, the acceptability of assisted dying varies according to the precise context. The 2005 BSA survey asked in more depth about attitudes towards assisted dying and end of life care. While 80% of respondents agreed with the original question, support fell to 45% for assisted dying for illnesses that were incurable and painful but not terminal.
A 2010 ComRes-BBC survey also found that the incurable nature of illness was critical. In this survey, while 74% of respondents supported assisted suicide if an illness was terminal, this fell to 45% if it was not.
It may not be surprising that support varies considerably according to the nature of the condition described, but it is important. First, because the neat tick boxes on polls belie the messy reality of determining prognosis for an individual patient. Second, because of the potential for drift in who might be eligible once assisted dying is legalised. This has happened in countries such as Belgium which became the first country to authorise euthanasia for children in 2014, and more recently in Canada where within months of the 2016 legalisation of medical assistance in dying, the possibility of extending the law to those with purely psychological suffering was announced.
It’s not just diagnosis or even prognosis that influences opinion. In the US, Gallup surveys carried out since the 1990s have shown that support for assisted dying hinges on the precise terminology used to describe it. In its 2013 poll, 70% of respondents supported “end the patient’s life by some painless means” whereas only 51% supported “assisting the patient to commit suicide”. This gap shrank considerably in 2015 – possibly as a result of the Brittany Maynard case. Maynard, a high-profile advocate of assisted dying who had terminal cancer, moved from California to Oregon to take advantage of the Oregon Death with Dignity law in 2014.
Even so, campaigning organisations for assisted dying tend to avoid the word “suicide”. Language is emotive, but if we want to truly gauge public opinion, we need to understand this issue, not gloss over it.
Information changes minds
Support for assisted dying is crucially known to drop-off simply when key information is provided. Back in the UK, a ComRes/CARE poll in 2014 showed 73% of people surveyed agreed with legalisation of a bill which enables: “Mentally competent adults in the UK who are terminally ill, and who have declared a clear and settled intention to end their own life, to be provided with assistance to commit suicide by self-administering lethal drugs.” But 42% of these same people subsequently changed their mind when some of the empirical arguments against assisted dying were highlighted to them – such as the risk of people feeling pressured to end their lives so as not to be a burden on loved ones.
This is not just a theoretical phenomenon. In 2012, a question over legalising assisted dying was put on the ballot paper in Massachusetts, one of the most liberal US states. Support for legalisation fell in the weeks prior to vote, as arguments against legalisation were aired, and complexities became apparent. In the end, the Massachusetts proposition was defeated by 51% to 49%. Public opinion polls, in the absence of public debate, may gather responses that are reflexive rather than informed.
Polls are powerful tools for democratic change. While opinion polls do show the majority of people support legalisation of assisted dying, the same polls also show that the issue is far from clear. It is murky, and depends on the responder’s awareness of the complexities of assisted dying, the context of the question asked, and its precise language. If we can conclude anything from these polls, it is not the proportion of people who do or don’t support legislation, but how easily people can change their views.
What our faces can tell other people about the state of our health
Our facial appearance influences how we feel about ourselves – and other people’s faces influence who we choose to approach or avoid and who we’d like to form romantic relationships with. At a glance, a face reveals a wealth of information about how we are feeling, or the kinds of behaviours we might be about to engage in – but what does it say about us when we aren’t expressing emotion? As it turns out, it’s more than you could imagine.
Over the past few years I’ve learned how aspects of our personality are present in our faces, how symptoms of depression cause faces to appear less socially desirable, and how wearing make-up changes perceptions of social traits – but the most important signals that our faces can give are of health.
The face is a biological billboard and we are expert readers, always interested in what it has to say. We are attracted to healthy-looking faces and avoid those who are unhealthy –- think of the sensation you might have had the last time you were on the train or a bus near someone who looked unwell – but it is the question of what makes a face look “healthy” in our eyes that is the most intriguing.
There are many historical examples of people altering their facial appearance to appear healthier. Things like the influence of body mass index (BMI) on face shape, or the smoothness of skin texture play a role in how healthy we are viewed to be, but it is actually facial colouration that seems to be the most important.
Early research has identified that faces with lighter, redder, and yellower skin were seen as the healthiest – and this was consistent across all ethnicities. There also seemed to be relevant biological processes associated with these colours: for example, lighter skin is associated with the ability to absorb more vitamin D. Greater redness, particularly when from oxygenated blood, may indicate more efficient circulation and blood supply to the skin.
But it is yellowness that seems to be particularly relevant for health, and for good reason: people with yellower skin tend to have healthier diets, rich in fruit and vegetables. The organic pigments in these foods, known as carotenoids, are hugely beneficial for health, and seem to be responsible for producing that desirable healthy glow. Intriguingly, tanning also increases skin yellowness and makes faces appear healthier, but the yellowness conferred by carotenoids (as a result, perhaps, of a healthy diet) is preferred to the yellowness brought about by tanning.
The secret to a healthy appearance isn’t as simple as eating more fruit and vegetables, however, it’s a bit more complicated than that – and healthy face colouration may be more nuanced than previously thought. Skin conditions such as dark circles under the eyes or rosacea, a condition which causes the skin to flush and redden, cause great concern to sufferers – Google searches of treatments or remedies return millions of hits. Both these conditions are also localised to areas of the face, which suggests colours in certain areas of faces could be relevant for looking healthy. Might these patterns of colour in faces, rather than the colour of the entirety of facial skin, be more relevant for looking healthy?
To answer this questions, we asked observers to rate faces for how healthy they thought they were, and calculated the colour differences between faces seen as very healthy and very unhealthy. We used Caucasian faces for the comparison, but there is some evidence that suggests how the overall skin colours of yellowness, redness, and lightness are seen as healthy in non-Caucasian faces too: it seems that everyone, regardless of race, finds these tones to be healthy.
Our research found that while yellowness across the whole face was a contributor to looking healthy, confirming earlier findings, lighter skin under the eyes and redder skin on the cheeks seemed to play larger roles. That colouration, in those areas, seemed to account for a lot more variation in health ratings than skin yellowness.
We subtly changed photographed faces to have lighter under-eye skin and redder cheeks – and also the reverse effect: darker under-eye skin and greener cheeks. Asking people to pick which they found the healthiest revealed a strong preference for the former pattern.
Interestingly, when we reversed the location of the colouration – lighter cheeks and redder under-eyes or darker cheeks and greener under-eyes – there was no clear preference. Given the wealth of research showing lighter skin and redder skin across the whole face is perceived as healthier this result was surprising. What this work suggests is that lightness and redness in our facial skin is seen as healthy, but only when it is under the eyes or in the cheeks, respectively.
In a final study, I looked at which facial area and colour was seen as the healthiest. While having redder cheeks and light skin under the eyes came out as looking equally healthy, dark skin under the eyes made people think the faces looked quite unhealthy, even more so than sickly-looking greener cheeks.
It is no surprise that cosmetic products such as concealer and blusher are so popular, since they increase a healthy looking colouration in the areas that matter the most to health perception – but nothing could ever beat a good night’s sleep and regular exercise.
