The neuroscience of Jeremy Clarkson

If humans can’t control themselves, they cannot be allowed the freedoms others enjoy: humans learn self-control, she says, in the same way that toddlers learn to control their bladders.

The great Jeremy Clarkson drama is, at heart, a question of neuroscience. Can our brains, formed and tweaked over millions of years, adjust to modern times? Or are we doomed to let their ancient structures rule for ever?

Perhaps it helps to compare Clarkson to Sims, the central character in Jennifer Haley’s brilliant play The Nether. Both are accused of an ongoing series of only vaguely defined transgressions. Both are largely unrepentant. They consider themselves to be beneficent figures: they provide pleasure and entertainment, albeit of a kind that is frowned on by many. Neither see grounds for criminal proceedings: it is the tenor of their lives and their general proclivities that the authorities seek to rein in.

The difference is that Sims is an entrepreneurial paedophile. In The Nether, the internet has become a fully immersive experience, gratifying all the senses. Sims has created a virtual world where customers’ avatars are free to have sex with childlike avatars – and even slay them with an axe, if they wish.

Is this wrong? It is an unsettling question for the audience, especially since the set makes the online world an immersive experience for them, too. The online children are not real; they are the online personas of consenting adults. No one is physically hurt. The uncomfortable truth is that we have no rules for how virtual adults should behave, even towards virtual children. Technology has already outrun the evolution of our morals.

Sims exploits this. His creation, he says, mitigates against people with his proclivities offending in the real world. Their brains make them do these things, he says. He is merely providing an alternative path of action. Does he have a point? The scientific literature certainly associates paedophilia with specific abnormalities in the brain. In 2003, the Archives of Neurology reported the case of a man whose brain tumour had caused him to start sexually molesting his eight-year-old stepdaughter. When the tumour was removed, his sexual interest disappeared.

This month, German researchers have reported that there is “growing evidence that paedophilia is linked to both structural and functional brain abnormalities”. One of those abnormalities is in the areas of the brain that deal with impulse control. The question is, does that make us any less inclined to condemn behaviour when those impulses are acted upon?

It seems not. The American neuroscientist and philosopher Patricia Churchland puts it like this: “An explanation is not an excuse.” If humans can’t control themselves, they cannot be allowed the freedoms others enjoy: humans learn self-control, she says, in the same way that toddlers learn to control their bladders.

This brings us back to Clarkson. Top Gear creates a virtual experience for those who have learned to control their bladders but not their impulses to do (or watch) silly or dangerous things. The programme’s appeal is often described as adolescent – and with good neuroscientific reason: in teenagers, the frontal lobes are not yet fully connected. These are the structures responsible for assessing consequences and making judgements. The Clarkson issue is about whether this half-formed physiology and the appeal of its world-view can justifiably be exploited and enjoyed by adults.

Now, though, someone has allegedly been physically hurt. The incident invokes ancient brain structures that flood us with deep-rooted but possibly anachronistic moral certitudes. We, the audience, are left in turmoil and yet utterly compelled to watch as the BBC’s moral dilemma plays out. Having had its way with Jeremy Clarkson for so long, should the corporation now control that impulse towards the axe?

Meet the evangelical Christian persuading believers that climate change is real

Katharine Hayhoe's Canadian missionary parents told her science and God were compatible. Then she moved to Texas. 

During Donald Trump’s presidential campaign, alarm rose with each mention of climate change. Denial, dismissal and repeated chants of “hoax” left no doubt as to his position.

Now President Trump’s withdrawal from the Paris Agreement has been seen as a seminal moment in the fight against climate change - one which many fear could lose the battle ahead of humanity.

But one scientist has been fighting a war of her own on the ground, against those who typically doubt the facts about global warming more than most - the evangelical Christian population of America.

And to make matters even more unusual, Katharine Hayhoe herself is an evangelical Christian who lives in the indisputably "bible belt" of Lubbock, Texas.

The atmospheric scientist has been named one of Time magazine's 100 most influential people and one of Politico’s 50 thinkers transforming American politics. Now she is using her considerable heft to speak to those who are hardest to convince that there is a manmade problem that threatens the Earth’s future.

I meet her at the science and music festival Starmus in Trondheim, Norway, where she is to address the attendees on Thursday in a talk entitled "Climate Change: Facts and Fictions".

Hayhoe was born in Canada, to missionary parents. Her father, a former science educator, showed her that there was no conflict between the ideas of God and science. However, it was something of a surprise to her when she discovered her pastor husband, whom she married in 2000, did not feel the same about climate change. It took her two years to convince him.

What started as a conversation became an organised project when she moved to America's South in the mid 2000s. 

“Moving to Lubbock was a culture shock," she tells me. "When I moved there I wasn’t doing much outreach, but it moved me in that direction.

“Lubbock is very conservative. It’s small and isolated.

“I would say the majority of people in Lubbock are either dismissive or doubtful about climate change. I was surrounded by people - neighbours, parents of friends, people at church, colleagues down the hall in the university - who weren’t convinced.”

So Hayhoe, who works as an associate professor and director of the Climate Science Centre at Texas Tech University, set to work. She began to collect the responses she was seeing to the climate change discussion and prepare her counter-argument.

“When I talk to people who are doubtful, I try to connect with the values they already have," she says. “The greatest myth is the myth of complacency - that ‘it doesn’t really matter to me’.

"But I would say that the second most insidious myth is that you only care about this issue if you’re a certain type of person. If you’re a green person, or a liberal person, or a granola person."

The stereotypes mean that people outside that demographic feel "I can't be that kind of person because that's not who I am", as she puts it.

Hayhoe convinced her husband using data, but rather than repeating a formula, she tries to find out what will resonate with different people: "For many groups, faith is a core value that people share.”

Whether she’s speaking to city planners, water company managers, school kids or Bible believers, Hayhoe says her hook is not the facts, but the feelings.

“I recently talked to arborists," she says. "For them, trees and plants are important, so I connect with them on that, and say ‘because we care about trees, or because we care about water or what the Bible says then let me share with you from the heart why I can about these issues because it affects something that you already care about’.

“My angle is to show people that they don’t need to be a different person at all - exactly who they already are is the kind of person who can care about climate change.”

Hayhoe came to public attention in the United States after appearing in a Showtime series on climate change. She has appeared on panels with Barack Obama and Leonardo DiCaprio, and launched a web series. As well as plaudits, this level of fame has also earned her daily threats and online abuse. 

“My critics think they’re coming from a position of religion, but they aren’t," she says. "They’re actually coming from a very specific political ideology which believes that the government should not have control over people’s lives in any way shape or form - very libertarian, free market, free economy, Tea Party."

She believes that in the United States, faith and politics has been conflated to the point "people can no longer tell the difference". 

“Now it’s conservatism that informs religion," she elaborates. "If the two are in conflict - like the Bible says God has given us responsibility over everything on this earth - then people say ‘oh, we can’t affect something as big as this Earth, God will take care of it anyway’."

Around half of those who attack her on social media identify themselves as Christians, she notes, but almost all call themselves conservatives. 

As a scientist, she’s been preparing data herself - naturally - on her online attackers, with depressingly familiar results.

“As soon as you stick your head out of the trench, you get it. There have been papers published showing that white men disproportionately form up that small group of dismissives. They’re almost all men. When I track my social media comments, I would say that 99.5 per cent of them are white men.

“Out of 1,000 negative comments, I have maybe five from women.”

After the climate change argument moved up a gear - following the Paris withdrawal - Hayhoe admits that she and her fellow scientists are concerned, although she pays tribute to the businesses, cities and states from the US that have committed to following the Paris agreement themselves.

On the subject of the chief white male denier, Trump himself, Hayhoe says she has a discussion point which she feels may convince him to think carefully about his role in the fight against global warming’s impact on humanity.

“I would attempt to connect with the values that he has and show him how acting on this would be in his best interests," she says.

“One guess would be ‘what do you want your legacy to be? What do you want to be known as, the man who destroyed the world, or the man who saved it?’”

Katharine Hayhoe is speaking at Starmus on Thursday June 22. For more details, visit Starmus.
