Dialling down the drama in the science and religion debate

In the first of a new series, biologist and priest Andrew Davison explores the perceived tension between science and religion, and the role identities play.

Andrew works at the intersection of theology, science and philosophy. He is Canon and Regius Professor of Divinity at Christ Church, Oxford.

Evolution isn’t just an idea for me; thinking about it has changed the course of my life. I arrived at university in the 1990s having been a member of a house church, full of the kindest people, but fundamentalist when it came to the Bible. I thought that the world was made in six days, six thousand years ago. When I realised that the evidence is stacked against the idea – to say theleast – it almost cost me my faith.  

I got through that crisis because friends introduced me to Christian thinkers from the Middle Ages, especially Thomas Aquinas (1224–1274). Far from representing an age of fear and ignorance (the ‘Dark Ages’), I found there an intellectual world that thrived on questions, with such philosophical sophistication that I was sure any of its chief exponents could have taken evolution in their stride. The struggle between faith and science lifted. Eventually, the sorts of questions that had previously kept me awake at night in worry, kept me awake in wonder. That was almost thirty years ago. Today, contemporary developments in evolutionary theory are one of the main strands of my work as a theologian. 

In two further articles, I will describe some of what’s so interesting, and disputed, in biology and evolution at the moment. In one, I’ll talk about the shift away from the idea that we can reduce everything down to the working of genes. That’s sometimes called an example of ‘nothing-but-ery’: here, the claim that our destiny is ultimately about ‘nothing but’ genes. In the other, I’ll talk about some of the ethical repercussions that those contemporary evolutionary developments might suggest, on such practical matters as good housing.  

In the rest of this piece, however, I will stick with the idea that it’s useful to see the idea of a tension between religion and science, not least over evolution, as being as much personal as intellectual. In particular, tensions over evolution in ‘science vs religion’ are caught up with questions of identity. Seeing oneself as a ‘religious crusader against science’ or a ‘scientific crusader against religion’ is an identity. It’s part of the story you tell about yourself, part of what you take pride in. Since these are also identities that define themselves in opposition to one another, they tend to extremes. Reconciliation involves renegotiating one’s identity.  

Nor is money insignificant. There’s money to be made in writing shrill and divisive books, but in calm and conciliatory books, not so much. Angry books create interest on social media. They find to an already energised readership. Moderate books, and authors who try to dampen the flames of animosity, don’t sell that well; neither do books that are willing to say ‘actually, these questions are more complex, or nuanced’. 

Evolution and economics  

Crucial in these questions of identity is the gulf between those seen as the ‘elite’ and those who don’t see themselves that way (a common theme in politics today). Why is a denial of evolution more common in poorer communities? It’s not only that these are people without educational advantages. It’s also that they feel on the disadvantaged side of an economic and cultural system. In that situation, people are typically all the more invested in what the system can’t take from them, such as their ethnicity, their religion, and its culture. Good on them for that. People in that situation will be all the more unwilling for others – whom they perceive as an elite, who enjoy all sorts of worldly advantages – to tell them what to think about their biological origins, bound up, as they are, with dignity, faith, and self-understanding.  

As an economically disadvantaged Muslim man once put it to me, ‘No one’s telling me that my faith’s stupid, or that I’m just some sort of monkey.’ There’s so much more going on in that statement than ‘being wrong about the science’.  

Moreover, disadvantaged people, and especially the majority who don’t have white skin, have been on the receiving end of prejudice cast in evolutionary terms. Teaching the theory of evolution – glorious though it is as a work of science – has a checkered moral history. That brings us back to monkeys. The ‘Scopes Monkey Trial’ (1925) has achieved iconic status, as the triumph of science over superstition in rural Tennessee, but it’s more complex than that. The prosecution, with its anti-evolutionary stance, was wrong to dismiss evolution as a matter of science. They weren’t wrong to be repelled by the science textbook at the heart of the case, which was uncomplicatedly racist, and indeed racist on supposedly evolutionary grounds. Evolution, it claimed, had produced lesser (black) and more advanced (white) races. As historians have also shown in recent decades, evolution was a powerful inspiration, into the early century, for advocates of cut-throat economics and politics: winner-takes-all, survival of the fittest, let the poor go to the wall.  

I’m not saying that every bit of opposition to evolution among poorer communities rests only on the ways that evolutionary theory has been used against them, but it is useful to remember that some of the religious opposition to evolution in the twentieth century came from a principled response to the unpleasant ethical, political, and economic positions to which – they were told – evolution gave support, including full-on advocacy for eugenic programmes of sterilisation of the poor, and contempt for the physically weak: all clothed in evolutionary garb. 

Drama critique 

The spectacle of a ‘science vs religion’ drama turns out to be about more than science, and also about more than theology or religious belief. It’s also about identity, advantage and disadvantage, about some deeply unpalatable economic and social positions, and even about making money out of writing books. There’s everything to be said for teaching biology well, and for arguing about the truth of evolution on scientific terms. I do a fair bit of that myself. There’s everything to be said for teaching theology well, and for arguing that it can take evolution in its stride. That’s even more my aim. But neither offers the full picture, and it’s not helpful to think that anyone who doesn’t believe in evolution is simply stupid or wicked. We won’t get very far, not even as advocates of science, unless are willing to listen. Unexpectedly, my experience is that the flagship scientific societies in the United States (where tension over evolution run so high) are better at this than they are in United Kingdom. 

Getting trapped in one end of some mutually reinforcing antagonism is hard to shake. It’s difficult to get to a nuanced position when you’re dealing with positions that are defined against each other. Whether arguments about evolution are part of your experience or not, there’s a wider message here, which we might all do well to take on board, asking ourselves whether positions of animosity can become unhelpfully baked into our sense of ourselves.  

Accepting evolution does not naturally, or inevitably, lead to brutal social Darwinism, but it’s been used that way in the past, more often than coverage of science today often lets on. We are by no means out of its shadow, even from under the shadow of eugenics. Being aware of that big, historical picture is useful, but it shouldn’t obscure the message from the beginning of this article, that these matters are fundamentally personal, and as much about how we see ourselves, and others, as they are about ideas. Reconciliation and understanding happen person by person, and person-to-person. 

You might think the work I’d most relish as a priest and scientist, or think most useful, would be reassuring religious people that evolution isn’t their enemy. That’s a good thing to do, but I’m actually even more thankful for opportunities to reassure scientists that religion can be thoughtful, unafraid, and even downright passionate about science. Turning up to dinner in my college still in my cassock after evensong, sitting next to visiting scientists, and asking intelligent, enthusiastic questions about their science can do as much good as all the lectures I give in churches or to theology students about the irreplicable value of science.

When someone makes a claim, ask yourself these questions

How stories, statistics, and studies exploit our biases.

“Check the facts.”  

“Examine the evidence.”  

“Correlation is not causation.”  

We’ve heard these phrases enough times that they should be in our DNA. If true, misinformation would never get out of the starting block. But countless examples abound of misinformation spreading like wildfire. 

This is because our internal, often subconscious, biases cause us to accept incorrect statements at face value. Nobel Laureate Daniel Kahneman refers to our rational, slow thought process – which has mastered the above three phrases – as System 2, and our impulsive, fast thought process – distorted by our biases – as System 1. In the cold light of day, we know that we shouldn’t take claims at face value, but when our System 1 is in overdrive, the red mist of anger clouds our vision. 

Confirmation bias 

One culprit is confirmation bias – the temptation to accept evidence uncritically if it confirms what we’d like to be true, and to reject a claim out of hand if it clashes with our worldview. Importantly, these biases can be subtle; they’re not limited to topics such as immigration or gun control where emotions run high. It’s widely claimed that breastfeeding increases child IQ, even though correlation is not causation because parental factors drive both. But, because many of us would trust natural breastmilk over the artificial formula of a giant corporation, we lap this claim up. 

Confirmation bias is hard to shake. In a study, three neuroscientists took students with liberal political views and hooked them up to a functional magnetic resonance imaging scanner. The researchers read out statements the participants previously said they agreed with, then gave contradictory evidence and measured the students’ brain activity. There was no effect when non-political claims were challenged, but countering political positions triggered their amygdala. That’s the same part of the brain that’s activated when a tiger attacks you, inducing a ‘fight-or-flight’ response. The amygdala drives our System 1, and drowns out the prefrontal cortex which operates our System 2. 

Confirmation bias looms large for issues where we have a pre-existing opinion. But for many topics, we have no prior view. If there’s nothing to confirm, there’s no confirmation bias, so we’d hope we can approach these issues with a clear head. 

Black-and-white thinking 

Unfortunately, another bias can kick in: black-and-white thinking. This bias means that we view the world in binary terms. Something is either always good or always bad, with no shades of grey. 

To pen a bestseller, Atkins didn’t need to be right. He just needed to be extreme. 

The bestselling weight-loss book in history, Dr Atkins’ New Diet Revolution, benefited from this bias. Before Atkins, people may not have had strong views on whether carbs were good or bad. But as long as they think it has to be one or the other, with no middle ground, they’ll latch onto a one-way recommendation. That’s what the Atkins diet did. It had one rule: Avoid all carbs. Not just refined sugar, not just simple carbs, but all carbs. You can decide whether to eat something by looking at the “Carbohydrate” line on the nutrition label, without worrying whether the carbs are complex or simple, natural or processed. This simple rule played into black-and-white thinking and made it easy to follow. 

To pen a bestseller, Atkins didn’t need to be right. He just needed to be extreme. 

Overcoming Our biases 

So, what do we do about it? The first step is to recognize our own biases. If a statement sparks our emotions and we’re raring to share or trash it, or if it’s extreme and gives a one-size-fit-all prescription, we need to proceed with caution. 

The second step is to ask questions, particularly if it’s a claim we’re eager to accept. One is to “consider the opposite”. If a study had reached the opposite conclusion, what holes would you poke in it? Then, ask yourself whether these concerns still apply even though it gives you the results you want. 

Take the plethora of studies claiming that sustainability improves company performance. What if a paper had found that sustainability worsens performance? Sustainability supporters would throw up a host of objections. First, how did the researchers actually measure sustainability? Was it a company’s sustainability claims rather than its actual delivery? Second, how large a sample did they analyse? If it was a handful of firms over just one year, the underperformance could be due to randomness; there’s not enough data to draw strong conclusions. Third, is it causation or just correlation? Perhaps high sustainability doesn’t cause low performance, but something else, such as heavy regulation, drives both. Now that you’ve opened your eyes to potential problems, ask yourselves if they plague the study you’re eager to trumpet. 

A second question is to “consider the authors”. Think about who wrote the study and what their incentives are to make the claim that they did. Many reports are produced by organizations whose goal is advocacy rather than scientific inquiry. Ask “would the authors have published the paper if it had found the opposite result?” — if not, they may have cherry-picked their data or methodology. 

In addition to bias, another key attribute is the authors’ expertise in conducting scientific research. Leading CEOs and investors have substantial experience, and there’s nobody more qualified to write an account of the companies they’ve run or the investments they’ve made. However, some move beyond telling war stories to proclaiming a universal set of rules for success – but without scientific research we don’t know whether these principles work in general. A simple question is “If the same study was written by the same authors, with the same credentials, but found the opposite results, would you still believe it?” 

Today, anyone can make a claim, start a conspiracy theory or post a statistic. If people want it to be true it will go viral. But we have the tools to combat it. We know how to show discernment, ask questions and conduct due diligence if we don’t like a finding. The trick is to tame our biases and exercise the same scrutiny when we see something we’re raring to accept.
