A Bayesian theory of death

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

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.

My problem with the polls

Chasing the polls hobbles the leadership we really need.

Recently reviewing the media’s coverage of the riots in the UK, I came across an article in The Telegraph that both surprised and annoyed me. It outlined an opinion poll conducted on the government’s response to the riots. It claimed that 49 per cent of the population were unhappy with the Prime Minister’s response to the riots. 

Now, you might be wondering why I was annoyed by the article. For me, IF opinion polling is to be used it has three principal applications. First, it might be used to understand how people intend to vote in an upcoming election. Secondly, polling might be used to inform governments or public organisations. They might want to understand how a policy could impact the general populus or a specific group of people. Or measure whether a policy is having its intended impact or not. Lastly, polling might be used by a government to gauge how its overall programme is being received by the population it was elected to serve.  

Polling, in my view, is not supposed to be used   to ask the general public about the day-to-day functioning and decision-making of a recently elected government. Again, you might wonder - why does this matter?  

Well, you don’t need to be a polling expert to know that trust in politicians in developed democracies around the world is at an all-time low. The prevailing view is that politicians are out for themselves, lack integrity, do not believe in anything in particular.  They are happy to provide their opinion based on whichever way the wind is blowing.  

The blame for this is often placed at the feet of those politicians. The argument is that the calibre of people choosing politics is far lower than it has been in previous generations. As such we have a group of leaders who do not believe in what they tell us. Others argue the toxic culture of social media, the overall decline in moral standards in Western democracies and the rise of the culture of the individual, also contribute to fewer common norms on moral expectations.  

All of these are true and do intensify the situation we find ourselves in. But I think there might be a more fundamental problem that is rarely addressed. Instead of politicians getting on with the job they have been elected and therefore delegated to do, they are constantly trying to please people instead of serve people. 

Politicians are having to constantly try and not say the wrong thing on social media or in a tough interview. They are, more and more being urged to respond to polls (often commissioned by the media) and the resulting stories about the day-to-day functioning of government. In any sphere of life, it is virtually impossible for any leader to make a good decision if they are constantly forced to question whether they are making the right decision not because it might harm the people they are leading or serving but because it might not be received well.  

If we want the calibre of our politicians to improve, our current crop needs the freedom to govern, oppose and lead without the need to please us. 

Both Jesus and St Paul spoke of the contrast in pleasing people instead of being led by God (or your convictions). Jesus said that you cannot serve two masters. You will either hate one and love the other or be devoted to one and despise the other. Here, the contrast in question is between money and God. But the principle remains the same. Politicians cannot govern effectively if they are trying to win a popularity contest at the same time.  

This does not mean that politicians should not be held accountable. They should be able to explain and justify the policies and decisions they make within the confines of the system that they have been elected into. In the UK, this includes Parliament, engagement with constituents, in-person surgeries and meetings, party management, and dialogue and examination by the media. It should not include weekly polling data which seems to serve the purpose of generating cheap content and fleeting headlines.  It prevents the politicians from taking difficult but necessary decisions and stifles debate on challenging topics.  

If we want the calibre of our politicians to improve, our current crop needs the freedom to govern, oppose and lead without the need to please us. They need to feel compelled to serve us. Not only will this lead to better decision making but it will also encourage ‘stronger’ candidates to enter politics knowing that they have the freedom to contribute to a better society for all.
