Shakespeare famously asked:

“What a piece of work is a man, how noble in reason, how
infinite in faculties, in form and moving how express and admirable, in action how like an angel, in apprehension how like a god! the beauty of the world, the paragon of animals—and yet, to me, what is this quintessence of dust?

Humans may be complex, capable of great heroism and deep depravity, yet it is worth stopping for a moment to look at the human body and mind to marvel in what we have become, and how we are made.

The visible design of the human body points out common features shared along with other members of the animal kingdom. Examples of these features are: two eyes, two ears, two nostrils, one mouth and four limbs, attached to a body and head. Detailed study of different seen parts of the body may, however, show some differences. For example, the presence of fingers and nails, hair distribution as well as a developed tail. While most members of the animal kingdom have teeth and a tongue, those two could also vary in their number and size, respectively, according to different species. Genetic investigations have shown that we humans share 99 % of our genes with animals, suggesting that our “earthly” component shares a common origin. Indeed, the twenty first century scientific findings match what is written in the Genesis story of creation, a story written over 3,500 years ago, well before genetic sciences came to light.

Creatures great and small

As for morphological differences between animal species, it is difficult to naively conclude why some are wild while others are man-friendly-even if the wild ones have different shapes, design, dietary habits, body size and life span. Other important observed features of the members of the animal kingdom are that they are all born, they all age, then ultimately die.

If we are to look at the unseen features of the members of the animal kingdom, we can again identify similarities. For example, all have a gastrointestinal tract, a cardiovascular system, a reproductive system, a respiratory system, a urinary system and much more. While these systems may differ slightly between species, the overall structure and function achieve similar purposes. For example, heart speed is faster in small animals like rats compared to big ones like elephants who have very slow hearts. Likewise, the respiratory system and the number of respiratory cycles per minute are significantly faster in running animals compared to the sedentary and slowly moving ones. Finally, the number of offspring also differs in different species, being just one at a time in big animals like elephants and horses, and many offspring in small animals like rabbits and mice. Such paradox between the number of offspring and animal size makes you think of the important determining role of the activity of those animals.

Unseen wonders

Now to turn to the rest of the animal kingdom and the unseen features of the human body. To start, let us look at the amazing functions of the human brain and its various functions. When humanity is sometimes described as the crown of creation, such a description is based on the superiority of human brain function and skills. Its sophisticated structure and how vital centres are created deep in the skull, to be protected from traumas, make you marvel. Also, the brain controls the different functions of the whole body, with its sensory and motor activities, various vital system functions including the lungs and the heart, all endocrine glands’ function, in addition to various receptors and centres that allow utmost precision and accuracy in everything we do. An example of this kind of precision is a doctor feeling a vein or an artery with the tip of a finger to insert a needle or a musician moving a finger a few millimetres while playing a violin, to produce the exact sound needed. Furthermore, the integrated function of human muscles, nerves and spinal cord is also amazing, let alone the synapsis between the nerve endings and muscle bundles, the chemicals secreted in them which allow electric stimulus transmission from the nervous system to achieve the motor function and desired movement.

The human brain also has the unique feature of storing knowledge. Of course, we should not ignore the importance of the training and programming ability of human brain. We learn how to drive a car, how to play games, how to study, how to operate safely on a sick patient. Such acquired skills are quite limited in other members of the animal kingdom. Moreover, the human brain has the unique ability to invent, discover, improve and correct errors it identifies.

Another very unique feature of human brain is its ability to conduct speech, a feature of humans that is under-developed in other members of the animal kingdom. While most animals can make noise and sounds, only humans can articulate words, sentences and even sing very complex songs. This unique ability seems to be the underlying mechanism behind the development of languages which are based on the human ability to talk and transmit information and knowledge by words and phrases.

The unseen brain has allowed human life to develop over time, building skills and achievements from generation to generation. Millennia ago, humans lived in huts together with animals, and now they build houses and palaces to live in. Centuries ago, we used donkeys, horses and camels to travel but now we use cars, trains, ships and airplanes. Our ancestors burned wood and coal to cook and to warm but now we use electricity to do these.

When we look carefully at the unseen parts of the human body, we also realize that we cannot alter any of it, despite the scientific advances made over the years. We can understand what harms our body and take measures to avoid it. Out of the ability of our brain to discover and invent, we have now produced science-based means for curing various diseases. Consider how we can replace a dysfunctional heart valve or a mobility-limiting joint. These inventions have resulted in a better quality of life, alleviating of symptoms, even helping to avoid early death, in some cases such as heart disease and cancer.

The heart of the matter

Another unseen source of life in humans is the heart. This fist-size organ is so complex in its structure and function. Recent scientific advances have enabled us to study heart function in milliseconds, hence the development of pacemaker treatments. They have also allowed clear imaging of the inside of the heart and the identification of pathologies, developments that guide practitioners to the optimum treatment of heart conditions. Recent discoveries have also allowed us to better understand how people develop coronary artery disease and how the pathology starts at the innermost layer of the arteries, particularly in individuals carrying significant risks for atherosclerosis including, smoking, high blood pressure, diabetes, high cholesterol and obesity. Amazingly, obesity has been shown to be the strongest underlying cause of other risk factors, hypertension, diabetes and hypercholesterolemia. So, nature cannot be blamed in many of these patients but our own patterns of behaviour. Science has shown that walking at least 5,000 steps each day, complying with the design of our body, reduces the likelihood of developing coronary artery disease by 15 per cent.

The unseen physiology of the rest of our body systems and the interaction between systems make us wonder how we are made. A rise of our body temperature by one degree due to a bug infection affects all body systems from the brain to the heart. A virus which cannot be seen by the most powerful microscope can destroy our lungs and cause premature death, as was the case with COVID-19 and others.

Finally, human inventions in the form of powerful microscopes have allowed scientists to study the human cell, which is the smallest living component of our body. Such small cells cannot be replicated in any factory in the twenty-first century, despite the vast scientific developments that surround us. You'll be surprised to learn how complicated and meticulously fine-tuned a human cell is and also how it functions, connects with other cells and other parts of the body. An example of this is the interaction between body minerals, calcium, sodium and potassium with heart and muscle individual cells. Such a function is critically controlled by many factors such as time, electric stimulation and pressure differences producing remarkably harmonious contractions and relaxation of the muscles without missing a beat.

The consequences of truth-telling are so severe our leaders can’t admit their mistakes

When accountability means annihilation, denial is the only way to survive

Why do our leaders struggle so profoundly with admitting error?

Media and inquiries regularly report on such failures in the NHS, the Home Office, the Department of Work and Pensions, HMRC, the Metropolitan Police, the Ministry of Defence, and so many more public institutions. Often accompanied by harrowing personal stories of the harm done.

In a recent white paper (From harm to healing: rebuilding trust in Britain’s publicly funded institutions), I defined “harm” as a holistic concept occurring where physical injury or mental distress is committed and sustained and explained that harm is generally something that is caused, possibly resulting in injury or loss of life.

When we look at harm from an institutional perspective, structural power dynamics inevitably oppress certain groups, limit individual freedoms, and negatively affect the safety and security of individuals. But when we look at it through the lens of the individuals who run those institutions, we see people who often believe that they are acting in good faith, believe that their decisions won’t have a significant impact, who don’t have time to think about the decisions they are making, or worse still, prefer to protect what is in their best interest.

Even well-intentioned leaders can become complicit in cycles of harm - not just through malice, but through their lack of self-awareness and unwillingness to put themselves in the shoes of the person on the receiving end of their decisions.

Martin Luther King Jr supposedly said, “the ultimate measure of a man is not where he stands in moments of comfort and convenience, but where he stands at times of challenge and controversy.” In contemporary politics, leaders are neither selected nor (largely) do they remain, because of their humility. Humility is synonymous with weakness and showing weakness must be avoided at all cost. Responsibility is perceived as something that lies outside of us, rather than something we can take ownership of from within.

So, why do leaders struggle so profoundly with admitting error?

The issue is cultural and three-fold.

First, we don’t quantify or systematically address human error, allowing small mistakes to escalate.

We then enable those responsible to evade accountability through institutional protection and legal barriers.

Finally, we actively discourage truth-telling by punishing whistle-blowers rather than rewarding transparency. Taken together, these create the very conditions that transform errors into institutional harm.

Nowhere is this plainer than in Baroness Casey’s recent report on Group-based Child Sexual Exploitation and Abuse that caused the Government to announce a grooming gangs inquiry. In this case, the initial harm was compounded by denial and obfuscation, resulting not just in an institutional failure to protect children, but system-wide failures that have enabled the so-called “bad actors” to remain in situ.

Recently, this trend was bucked at Countess of Chester Hospital where the police arrested three hospital managers involved in the Lucy Letby investigation. Previously, senior leadership had been protected, thus allowing them to evade accountability. Humble leadership would look like acting when concerns are raised before they become scandals. However, in this case, leadership did act; they chose to bury the truth rather than believe the whistle-blowers.

Until we separate admission of error from institutional destruction, we will continue to incentivise the very cover-ups that erode public trust.

The answer to our conundrum is obvious. In Britain, accountability is conflated with annihilation. Clinging onto power is the only option because admitting error has become synonymous with career suicide, legal liability, and is tantamount to being hanged in the gallows of social media. We have managed to create systems of governing where the consequences of truth-telling are so severe that denial is the only survival mechanism left. We have successfully weaponised accountability rather than understanding it as the foundation of trust.

If Rotherham Metropolitan Borough Council had admitted even half of the failures Alexis Jay OBE identified in her 2013 report and that Baroness Casey identifies in her 2025 audit, leaders would face not only compensation claims but media storms, regulatory sanctions, and individual prosecutions. It’s so unthinkable to put someone through that that we shrink back with empathy as to why someone might not speak up. But this is not justice. Justice is what the families of Hillsborough have been seeking in the Public Authority (Accountability) Bill: legal duties of candour, criminal offences for those who deliberately mislead investigations or cover-up service failures, legal representation, and appropriate disclosure of documentation.

Regardless of your political persuasion, it has to be right that when police misconduct occurs, officers should fear not only disciplinary action and criminal charges. When politicians admit mistakes, they should face calls for their resignation. Public vilification is par for the course. Being ejected from office is the bare minimum required to take accountability for their actions.

The white paper shows that the cover-up always causes more damage than the original error. Institutional denial - whether relating to the Post Office sub-postmasters, the infected blood scandal victims, grooming gang victims, Grenfell Towers victims, Windrush claimants, or Hillsborough families - compounds the original harm exponentially.

In a society beset with blame, shame, and by fame, it is extraordinary that this struggle to admit error is so pervasive. Survivors can and will forgive human fallibility. What they will not forgive is the arrogance of institutions that refuse to acknowledge when they have caused harm.

The white paper refers to a four-fold restorative framework that starts with acknowledgment, not punishment. The courage to say “we were wrong” is merely the first step. Next is apology and accountability followed by amends. It recognises that healing - not just legal resolution - must be at the heart of justice, treating both those harmed and those who caused it as whole human beings deserving of dignity.

Until we separate admission of error from institutional destruction, we will continue to incentivise the very cover-ups that erode public trust. I was recently struck by Baroness Onora O’Neill who insisted that we must demand trustworthiness in our leaders. We cannot have trustworthiness without truth-telling, and we cannot have that without valuing the act of repairing harm over reputation management. True authority comes from service, through vulnerability rather than invulnerability; strength comes through the acknowledgement of weakness not the projection of power.

We must recognise that those entrusted with power have a moral obligation to those they serve. That obligation transcends institutional self-interest. Thus, we must stop asking why leaders struggle to admit error and instead ask why we have made truth-telling so dangerous that lies seem safer.
