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.

Families like mine are impossible now, thanks to the idol that is the net migration target

Politician priests are making pointless sacrifices on the altar of numbers

Joel Pierce is the administrator of Christ's College, University of Aberdeen. He has recently published his first book.

Let me tell you a love story. Eighteen years ago, in a time before politicians had taken to immolating their values on the altar of the semiannual net migration totals, I fell for the pretty Scottish bridesmaid at my sister’s wedding. The romance presented some challenges for an American like me, but none that were insurmountable. She found a year-long internship near me in Seattle and, just before she returned home, I popped the question.  

The process of applying for a UK visa was just another bit of the tedious logistics of an overseas move, the kind of thing a romantic comedy skips over with a ‘One Year Later’ movie subtitle so that it can end with a joyous wedding ceilidh in a picturesque Scottish locale. Our first few years together in Edinburgh were lean ones. Having takeaway coffee more than once a week felt like a scandalously indulgent luxury. Even so, I was able to progress seamlessly from my marriage visa to indefinite leave to remain, to citizenship.   

None of this would be possible if we were young twentysomethings in love today. We would fail every test of what the Home Office now considers to be acceptable romance.  

During our first year of marriage, the stipend my wife received while training for ministry would have been well short of the £18,600 income threshold introduced in 2012 for a sponsoring spouse, let alone the £29,000 required now. While we did have some savings, they were nowhere near the £88,500 now needed to waive the income requirement, and, in any case, would have been substantially drained by the £5,000 in fees and health surcharges that a two-and-half-year spouse visa now costs. It is little wonder Brits who have found love abroad, even ones in a substantially better financial and professional position than we were then, are now finding it impossible to move back to the UK.  

What is the cause of these new barriers? A hint can be found in the title of a recent Guardian article about recommendations for a slight relaxation of the income threshold to between £23,000 to £25,000. ‘Lowering UK’s income requirement for family visas ‘would increase net migration’, the piece was headlined. When even the most left wing major daily in Britain can’t report on the possibility of things being marginally easier for Brits who have the temerity to love a non-citizen, without framing it in terms of net migration, it’s a sign that we have all fallen captive to this singular statistic.  

Net migration is a number created by humans and yet it has come to play the role of an angry god which demands sacrifices every time it is reported. The right of working class people to marry a non-citizen spouse, the economic viability of our universities, and the proper staffing of the NHS are all victims its politician-priests have offered up in hopes that they would satiate its hunger. Net zero maybe next. 

There is no particular reason to think totting up the total number of people who arrived in the UK with the intention of staying here for a year and then subtracting the total number who left with the intention of staying abroad for a similar duration is a particularly meaningful exercise. It conflates people like me, who came here with every intention to settle and start a family, with students coming for a one-year master’s, doctors filling vital roles in NHS with children try to stay with with a migrant parent and Afghan refugees seeking long-term sanctuary with oil workers serving time in Aberdeen before moving on to Calgary or Brunei.  

The dominance of this statistic in our discourse has warped our moral discernments. 

There are perfectly legitimate reasons to think carefully about how much of each form of migration to allow, but when they are all grouped together under this single measure a peculiar logic sets in. Want to do the right thing by welcoming refugees from Ukraine and Hong Kong? Well, then, we’ll have to offset that with restricting visas for overseas students and throwing our higher education sector into chaos. Need more highly skilled programmers working in banks in London? Well, maybe we can balance that by demanding care workers abandon their kids if they want to look after someone in Nottingham. There is no reason to weigh the needs of these different sectors against each other, and yet the logic of this statistic demands that we do. 

The Bible has a word for human-made things which take on their own singular, violent logic. It calls them idols. While that word may conjure images of golden calves, the accusation which biblical writers consistently make against idolaters, that their idols blind them to what is really important and numbs their critical thinking, applies equally well when the idol is a statistic. The dominance of this statistic in our discourse has warped our moral discernments. It has made us unable to say what should be said without glancing nervously at its imposing shadow. It causes us to say things that should never be said and not notice how absurd they are. 

Instead, we should be able to celebrate that hundreds of thousands of people want to come to study at our universities (the vast majority of whom return home after finishing their studies)  and, hopefully, someday also be able to celebrate when hundreds of thousands of refugees are able to return to a peaceful and liberated Ukraine without having to calculate that the former will raise and the latter lower our totals. We should be able to welcome easing of income restrictions on spouse visas without noting that it will lead to a marginal increase in net migration. We should be able to see that sending an eight- and eleven-year-old back to Brazil without their parents is not, in the words of a Home Office official, “a degree of disruption in family life” which is “proportionate to the legitimate aim of maintaining effective immigration control”, but rather a gross violation of human decency. 

Migrants are not just numbers on a balance sheet. The diversity of our lives, what we give to the UK, what we receive in return, cannot be summed up in a single annual figure. And yet every six months, as the figure comes out, politicians express disappointment and announce measures to put that little bit of extra pressure on us, so that maybe a few more of us who can leave will. In the process they are sacrificing to this idol not just the peace of mind and the economic well-being of many migrants, but also much of the vitality of the nation as a whole. The Bible has a solution for idols. They are only fit to be melted down, destroyed, and forgotten. It is time to consider giving this one a similar treatment.
