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.

Getting hitched should benefit more than the advantaged

Marriage’s decline impacts outcomes for all.

Of all the dramatic changes to Britain in the last half century, one of the least discussed is the extraordinary decline in marriage.  

The marriage rate has fallen by two-thirds in the last 50 years. It was just above six per cent in 1972 and has now been under two per cent since 2017. 

This remarkable decline has corresponded with a rise in a relatively new relation type: cohabitation. Cohabitation was extremely uncommon before the 1960s, and even by 1986 just 10 per cent of new mothers were cohabitants. It is, however, rapidly becoming the mainstream. Now 35 per cent of babies are born to cohabiting mothers, and the total number of UK cohabiting couples increased from 1.5 to 3.7 million between 1996 and 2022.  

Much of this is due to couples delaying marriage: 84 per cent of religious and 91 per cent of civil marriages are now between couples that already live together, and the average age when first marrying has climbed by 10 years since the early 1970s. But it is also due to many more couples not marrying at all. 

Opinions understandably differ on this social transition away from marriage and towards cohabitation. It is a point of progress worth celebrating that the previous societal shunning of those, especially women, who had children outside of marriage has been left in the past. However, such progress has not been without consequences. Cohabitations are less stable, on average, than marriages. Cohabiting parents are around three times as likely to separate in the first five years of their children’s life as married couples.  

This stability is not simply because wealthier, more highly educated people tend to have stable families and also tend to marry. Studies by World Family Maps and the Marriage Foundation have shown marriage to be a larger factor in family stability than either education or income.  

Nor does the stability come from couples staying together miserably.  Studies undertaken in 2017 and 2024 looked at the outcomes of couples 10 years on from considering their relationships to be ‘on the brink’. In the initial study, while 70 per cent of cohabiting couples had separated in the decade since considering themselves ‘on the brink’, 70 per cent of the married couples had remained together. Perhaps even more crucially, just seven per cent of those married couples that had stayed together were unhappy in their relationship a decade on. The 2024 study found none of the sample of married couples that had stayed together were still unhappy 10 years on. For those that had stayed together, things had improved. 

This family instability that the decline of marriage has caused is also unevenly distributed. Affluent couples – often those most likely to criticise the concept of marriage – are much more likely to marry than disadvantaged ones.  

Looking at socioeconomic groups, seven in ten mothers from the most advantaged group are married, while just a third of those from the two most disadvantaged groups are. The effect is geographic, too. Institute for Fiscal Studies research has found parents having children are more likely to be married if they are living in better educated areas. For the advantaged, it is compassionately affirmational to suggest that every relationship is equal, even though the advantaged themselves choose the most secure option of marriage: a hypocrisy only tolerated due to the potent fear of seeming judgemental. 

The consequence of this is deepening inequality: disadvantaged families are rendered more likely to breakdown, while children from affluent backgrounds are disproportionately likely to enjoy the ‘the two-parent privilege’, the substantial emotional and developmental advantages of growing up in a stable home. Melissa Kearney coined the phrase, and her evidence shows how children grow up, on average, to have better educational outcomes, better emotional and physical wellbeing, and higher incomes if they are raised in two-parent homes. 

Stable families are foundational to a stable society, and marriage is crucial to stable families.

So, why are marriage rates so much higher among wealthier couples than poorer ones, and why is this gap growing? 

We can isolate three reasons in particular, each more solvable than the last.  

Most challenging is the feedback loop effect: people whose parents, role-models, and friends have not married are unlikely to do so themselves. The demographic trend compounds itself.  

Second, and easily addressable if only the will was there, is the public messaging effect: politicians – and to some extent celebrities – have consistently told the public that marriage is unimportant. In 2017, Marriage Foundation research found that it had been a decade since a cabinet member had discussed marriage in a speech. This has hardly changed in the years since. In 2024, the only major party whose manifesto even mentioned marriage was Reform; even then the focus in the relevant section seemed to be less on marriage and more on getting ‘people trapped on benefits back into the workplace’. 

Third is the cost of weddings. A quick flick through top wedding magazines suggests that the average wedding costs upwards of £20,000. Survey evidence from both Marriage Foundation and the Thriving Center of Psychology have found that most young people view weddings as unrealistically expensive. 

This financial problem is solvable: much of the costs relate to venue hire. Unless they are having a religious marriage, a couple will need to find a venue that has gone through the bureaucratic process of becoming an ‘approved premises’. The cheapest of these are register offices which, including all expenses, still cost about £500. 

This is eminently mendable. The Law Commission proposal to reorganise wedding law around the officiant, not the venue, opens the door for a future of more affordable weddings by removing the regulatory barrier. It will also bring the law in line with that of other home nations. 

This proposal will not work by itself, though, it will need to be supported by creativity in wedding planning.  

Wedding costs can be substantially reduced by taking a DIY approach. Food, drinks, and decorations can often be coordinated amongst enthusiastic (and appropriately competent!) guests.  

Booze free weddings are a growing phenomenon, and especially good for weddings with children.  

Such ‘group-effort’ approaches often have a unique feel thanks to the high participation of guests, and people are more likely to remember events that they feel a sense of ownership of, having helped make them happen. 

Alongside this is a recommendation by the Centre for Social Justice. It proposes subsidising the necessary statutory fees for the poorest couples, up to £550 per couple. An inexpensive and hugely beneficial adjustment to improve wedding accessibility for the least fortunate.  

Stable families are foundational to a stable society, and marriage is crucial to stable families; perhaps it is time for all of us to make tying the knot easier.
