A Bayesian theory of death

The sinking of the superyacht displays the probability, and banality, of death.

George is a visiting fellow at the London School of Economics and an Anglican priest.

Rescue workers look at the plan of a yacht.
The search for the Bayesian.
Vigili del Fuoco.

On any statistical calculation, the probability of dying by drowning when your luxury yacht suddenly and inexplicably sinks at anchor in the Mediterranean has to be extremely low. 

So it’s the cruellest of ironies that tech tycoon Mike Lynch should so die, along with his daughter and five others, having devoted his commercial life to the application of such statistical probabilities. He had named his yacht Bayesian after the 18th-century theorem that introduced the idea that probability expresses a degree of belief in an event. 

That doesn’t expressly mean religious belief. But, intriguingly, it doesn’t exclude it either. According to Thomas Bayes, who published his theorem in 1763, the calculable degree of belief may be based on prior knowledge about an event, such as the results of previous experiments, or on personal beliefs about it. 

In essence, you don’t believe your yacht will capsize in the night and sink in seconds, because your experience tells you so. That belief can mathematically be included in the probability of it happening. 

We can transfer the method into religious praxis. Christian belief in the event of resurrection, for instance, can be calculated in the probability that the deaths of the Lynches and others aboard the Bayesian are not the end of their existence. 

It’s an intriguing legacy of Lynch’s work for theologians. But it’s the sheer lack of probability of the lethal event occurring at all that lends it its random banality. It’s that death visited those asleep on a yacht in the small hours that lends this news story such tireless legs, not just that these were super-rich masters and mistresses of the universe. 

There have been bitter observations on social media that the Bayesian’s victims have commanded limitlessly greater attention than the many thousands of refugees who die in small-boat crossings of the Mediterranean every year.  

This is a category mistake. And again, Bayesian theory can be deployed. Experience supports our belief that crossing the sea in overcrowded and unseaworthy vessels can all too often lead to tragically terminal events. The probability of death is plain. Again, it’s the sheer randomness of the Bayesian yacht event that sets it apart. 

If death can visit at any time, there can be no difference in the valuation of long or short lives. 

That randomness brings us back to the banality of sudden death among us, almost its ordinariness, something that just happens, often entirely out of the blue. The prayer book has the funeral words “in the midst of life we are in death”, meaning that death is our constant living companion. But that doesn’t quite cut it for me, because it tells us it’s there, but nothing of its true significance. 

The tenets of Christian faith are regularly said to be those of a death cult; that it’s a deep-seated fear of death that leads us to avoid it with assurances of eternal life. But it’s the sheer banality of death, as displayed in the randomness of the Bayesian event, that seems to knock down that idea. In its randomness, death looks ridiculous rather than evil. 

Conspiracy theories around the sinking of the Bayesian are a kind of denial of the reality of death too. We want there to be more to it than the utterly banal.

Author Hannah Arendt coined the phrase “the banality of evil” when covering the trial of Nazi holocaust architect Adolf Eichmann in Jerusalem. I’d want to suggest that it’s that same banality, that basic human ordinariness, that is the real nature of the supposed grim reaper, rather than his evil.   

None of this can comfort the Lynch family, who mourn the loss of a much-loved father and his young daughter, or the families of the others who lost their lives on the Bayesian. But it is meant to go some way towards an explanation of what we mean in Christian theology when we bandy about phrases such as “the defeat of death”. Because it’s not a wicked serpent that’s been defeated, more of a pointless clown. 

There is something especially painful about the death of the young, such as that of 18-year-old Hannah Lynch on the Bayesian that night, a young woman on the threshold of life. And – God knows – the even younger lives we’ve read about being taken lately. 

But the concept of banality may lead us to another tenet of faith: The completeness of every life. If death can visit at any time, there can be no difference in the valuation of long or short lives.  

A poem, often ascribed to a former dean of St Paul’s cathedral, begins with the line: “Death is nothing at all.” That’s wrong, as an idea. Death is as significant an event as birth. But its defeat is in keeping it in its place. 

The dignity in simplicity with which football manager Sven-Göran Eriksson greeted his final illness is a masterclass in this tactic for life. Death isn’t to be negotiated, it’s just there. 

In the end, death isn’t a Bayesian probability, it’s a certainty, for all of us. The difference, in Bayesian theory, must be the belief we bring to our personal calculations of the probability of the event.

The Post Office scandal: why truth matters

Lawyer Alex Stewart analyses the Post Office scandal for the lessons it teaches on our missing morals.

Alex Stewart is a lawyer, trustee and photographer.  

A man, dressed in a suit and anarak, stands in front of a law court.
Toby Jones plays the eponymous Mr Bates in ITV Studios dramatisation.

The reaction to ITV's 4-part dramatisation of the The Post Office Horizon story has been profound. It managed to stir up huge public sympathy for the sub postmasters and has galvanised the Government into action. The story has also tapped into deep wells of moral outrage at a time when trust in our institutions and corporations is the lowest in living memory. It’s a tale of failure to take responsibility. It’s a tale that shows the truth matters. 

A failure to take responsibility 

What seems to have enraged us most is the collective moral failure over many years of those in positions of power. They either deliberately covered up the problems with the Post Office’s Horizon IT system, by withholding information about known faults, or simply ignored them.  The sense of disbelief has been compounded by the apparent inability, so far, to pin the blame on any one person or group of people. The Post Office’s ex CEO, Paula Vennells, has handed back her CBE but it seems she was only the tip of an iceberg of obfuscation and prevarication.   

What emerges is a pattern of behaviour that moral philosophers call moral diffusion. It is also called the ‘bystander effect’, so-called after a case in which a woman was attacked in New York in the presence of a large number of people who knew that she was being assaulted but failed to come to her rescue as they all saw it as someone else’s problem. 

I witnessed an example of this the other day in London at a busy pedestrian crossing. A man with an angle grinder was cutting through a bicycle lock.  As the sparks flew, pedestrians looked at each other for reassurance, as if to ask - is this ok?  Was he shamelessly stealing the bicycle, or had he been sent by the council to remove a long-abandoned bicycle?  No one knew and no one intervened. 

The instinct to shirk responsibility seems to be hardwired into us, part of our fallen nature.  It all started with Adam and Eve. Embarrassed and ashamed they hide, only to discover you cannot hide from God. And when they are discovered, both deny personal responsibility, saying in effect “it wasn’t me”.  

Later we have the story of Cain killing his brother Abel. Cain doesn't deny he has done something wrong, he simply denies he had any responsibility for his brother at all.  He asks why he should have any concern for anyone beyond himself. ‘Look after Number One’ Is the voice of Cain throughout the ages. 

Why is this failure of leadership such an effrontery to us? Because we instinctively recognise that leadership is not about lording it over others. 

The Government has promised to hold to account those responsible for the scandal.  Perhaps the roving searchlight of the inquiry will succeed in identifying the human culprits? In the meantime, executives and politicians are scrambling over themselves to deny responsibility, typified by the response of Sir Ed Davey who has taken the art of the non-apology to a new level. The honourable exception, among the political class, is Lord Arbuthnot who as an MP was both tireless and fearless in campaigning for justice for the sub-postmasters.     

Why is this failure of leadership such an effrontery to us? Because we instinctively recognise that leadership is not about lording it over others, hiding behind other people’s decisions or passing the buck, it is about taking responsibility.  In practice we do not live by the philosophy presented by Glaucon in Plato’s Republic, that justice is whatever is in the interest of the stronger party.  Nor are we willing to live in a Darwinian world where in the struggle for supremacy there is no need for the powerful to look out for the weak simply because they are powerful.    

There is a fascinating moment in the story of Moses in the book of Exodus when he notices an Egyptian official beating one of the Israelite slaves. He sees that no one else is willing to intervene and he gets involved, at some personal risk, and in so doing marks himself out as a leader.   

Leadership is born when we become active not passive, when we decide that something is wrong and we need to take steps to put it right. These are the people who make the world a better place because doing nothing, though it may not be illegal, is not morally neutral. Failing to act to prevent a wrong does not simply leave a vacuum, it gives permission for evil to flourish. Or as Burke put it “The only thing necessary for the triumph of evil is for good people to do nothing.”   

Alan Bates could have resigned himself to his fate, but instead has doggedly pursued justice for 20 years.  

We all long for leaders who will lead responsibly and not out of self-interest, who will not turn a blind eye to the suffering of the powerless or blame others when asked to explain why they did nothing.   

This is especially so in the church which holds itself to a higher standard and should know better. The ITV series quite deliberately dwells on the fact that Paula Vennells was, as well as being CEO of the Post Office, ordained in the Church of England.  

The truth matters 

Key to the success of the sub-postmasters case was the ability to get to the truth, a task made very difficult by the fact that the Post Office held all the records needed to prove that it was the Horizon system, not the sub-postmasters, that was at fault.   

Being able to determine the truth of a matter is essential to how we lead our lives, and especially in matters of justice.  The version of events presented by the Post Office turned out to be false, but once this false version was on record, the reputations of otherwise upstanding pillars of local communities were destroyed overnight.  The public shame and the human cost of being cruelly and wrongly labelled a liar and thief is powerfully brought home by the TV series, as is the relief of vindication. 

We do not in reality live our lives in a postmodern universe where truth is seen as relative (Oprah’s infamous “What is your truth?” moment), or nothing more than a claim to power.  We know on a daily basis the power of the truth to set us free, from false accusations or a guilty conscience, and how much it stinks when we are deceived - especially when it is by the powerful.  

A lack of integrity 

During the Cold War, there was a running joke that the best indicator of whether a country operated as a one-party state was whether it had the word “Democratic” in its name.    

We have become used to the same kind of dissonance between image and reality, whether it is the smiley telegenic people in a company’s glossy videos (actors? library footage?) or an impossibly worthy values statement.

I was once part of group of employees invited to revamp our employer’s declared values. We were presented with a set of aspirational statements that described a culture that was akin to the Garden of Eden and a working environment that bore no relation to the reality.  When I pointed this out, I was not invited back.   

In public Paula Vennells was insistent that the Post Office cared about its people while out of the spotlight those people were being horribly mistreated.   

It isn’t always so, but how can so many organisations live with such glaring contradictions?  Or is it that boards become so disconnected, by geography or otherwise, from the organisations they run and the cultures they preside over that they actually believe the image over the reality?  

"Computer says no"

One of the more terrifying issues raised by the Post Office scandal is how the principle of the presumption of innocence was abandoned.  How come the testimony of hundreds of innocent people was rejected in favour of a faulty computer system’s data?  

Part of the problem is that the English courts regard computer records as reliable unless the defendant can show otherwise. Since 1999, the burden of proof - and with it the presumption of innocence – has effectively been reversed: the defendant is guilty unless he can show that the computer records implicating him are wrong.   

The notion that we cannot challenge a computer that “Says No” is a real problem. As the Post Office scandal shows, computer software is often riddled with bugs. After all, it is written by fallible human programmers. It also became clear that the Horizon system’s data could be manipulated remotely - and without the knowledge of the sub postmasters.  

To assume that computer generated evidence is infallible is a very dangerous assumption in a world increasingly dominated by machines and, more recently, artificial intelligence.   

A very human story 

The sub-postmasters in the Post Office case were not machines or assets.  The ITV drama succeeded in doing what no legal or investigative process can adequately do, it humanised the victims. Despite all the PR talk about caring for its people, the Post Office only cared about its own reputation, and in the process of trying to save itself lost its humanity and its reputation.   

The drama successfully stripped away all the lifeless procedural, technical and legal terminology to reveal a very simple, devastatingly human story that needed to be told. In Alan Bates’ words: “the Post Office stole my livelihood, my shop, my job, my home, my life savings and my good name”.   

This Post Office story has struck a chord because it reminds us of is what is increasingly missing in public life - leadership, accountability, respect for the truth, integrity and humanity. 

Watching the ITV drama, I was frequently moved to tears and cheered at the end. We root for the victims out of solidarity, as if we ourselves had been wronged.  

The Christian understanding of sin identifies it as a public not a private matter, as it infects the whole body politic.  This is why the case name given to a crime is “R (that is, the state) v X”. There are certain wrongs which are so serious they are considered to be offences against the whole community, not just the individual victim.  

The Post Office saga is a parable of our times.  It tells a story of a society whose elites have become dangerously detached from principle and deaf to the concerns of ordinary people. It will not go away any time soon. The moment of true catharsis, if it comes, will be when our institutions and leaders have earned back our trust. 

The last word goes to the book of Proverbs: 

When good people run things, everyone is glad, but when the ruler is bad, everyone groans.
