Naomi Wolf's "Vagina" is full of bad science about the brain

Given that she's written a book about the vagina, Wolf seems to mention the brain a lot.

Naomi Wolf has a new book out. Here’s an extract. It’s proven controversial. I’m not going to discuss Wolf’s politics, nor will I mention the famous "pasta incident" as I don’t think I can write anything sensible about that event. I am however a neuroscientist, and for a book about the vagina, Wolf seems to mention the brain a lot.

So let’s see how brainy it is.

Words, when deployed in relation to the vagina, are always more than "just words". Because of the subtlety of the mind-body connection, words about the vagina are also what philosopher John Austin, in his 1960 book How to Do Things with Words, calls "performative utterances", often used as a means of social control. A "performative utterance" is a word or phrase that actually accomplishes something in the real world. When a judge says "Guilty" to a defendant, or a groom says "I do", the words alter material reality.

Studies have shown that verbal threats or verbal admiration or reassurances can directly affect the sexual functioning of the vagina. One suggests that a stressful environment can negatively affect vaginal tissue itself…

True of course, but it’s nothing to do with vaginas specifically. Threats, admiration and reassurances all influence our stress levels, and stress can affect the function of the vagina. But the same could be said for any other organ: stress also affects the heart, the stomach, and even the penis.

What’s more, the study Wolf linked to in support of her idea that “a stressful environment can negatively affect vaginal tissue itself” was in rats.

Moving on:

In 2010, male Yale students gathered at a "Take Back the Night" event, where their female classmates were marching in a group, protesting against sexual assault. The young men chanted at the protesters: "No means yes and yes means anal." Some of the young women brought a lawsuit against the university, arguing that tolerating such behaviour created an unequal educational environment. Ethically, they are in the right, and neurobiologically, they are right as well. Almost all young women who face a group of their male peers chanting such slogans are likely to feel instinctively slightly panicked. On some level they are getting the message that they may be in the presence of would-be rapists, making it impossible to shrug off immature comments, as women are often asked to do…

Yes, women faced with such behaviour may feel panicked.

That’s common sense.

There’s nothing “neurobiological” about it – well, no more so than anything else in life. Everything we feel, think or perceive affects the brain – that’s how we feel, think and perceive. Everything is neurobiological – try doing anything without a brain, if you don’t believe me – so it’s misleading to focus on particular incidents as being somehow more neural, and therefore more real, than others.

These women’s panic is neurobiological… but no more neurobiological than the events occurring in the brains of their abusers, who, presumably, experienced a pleasurable release of dopamine and other "happy hormones" and probably reduced stress levels to boot.

Does that mean it was OK? Of course not! Because the Yale incident is not about the brain.

It gets worse.

Sexually threatening stress releases cortisol into the bloodstream, which has been connected to abdominal fat in women, with its attendant risks of diabetes and cardiac problems; it also raises the likelihood of heart disease and stroke. If you sexually stress a woman enough, over time, other parts of her life are likely to go awry; she will have difficulty relaxing in bed, as well as in the classroom or in the office.

True enough, but all stress releases cortisol into the bloodstream, which has been connected to abdominal fat in both men and women… and so on. Stress is bad. I think we can all agree on that. Cortisol, in excess, is probably bad in the long term, although not many people realize that not having enough cortisol is also bad, indeed it’s a medical emergency and can kill.

What’s more, few know that "good" stress, such as physical exercise, also releases cortisol in most people, and people injected with high doses of cortisol often enjoy it (“the most common adverse effects of short-term corticosteroid therapy are euphoria and hypomania [the ‘high’ phase of bipolar disorder].”)

Cortisol’s complicated.

Wolf then writes:

This [stress-induced cortisol release] in turn will inhibit the dopamine boost she might otherwise receive, which would in turn prevent the release of the chemicals in her brain that otherwise would make her confident, creative, hopeful, focused – and effective, especially relevant if she is competing academically or professionally with you.

Stress and cortisol have repeatedly been shown to increase dopamine release. In some studies. Other studies show they decrease it. It’s complicated, in other words.

Dopamine is complicated, and really rather fascinating if you’re into that kind of thing. It acts on at least five different types of receptor, and what it does depends on the receptor type; there are four major dopamine “pathways” in the brain, one of which (the mesocortical pathway) is thought to inhibit another (the mesolimbic pathway) – and plenty of subdivisions beyond that.

Cortisol is, as we’ve seen, complicated too. Don’t get me started on surface vs nuclear receptors, mineralocorticoids vs. glucocorticoids, and the hypothalamopituitary axis. Unless you’re a neuroscientist, you don’t want to know. It’s not relevant. Neither is Wolf’s simplified version of it.

Finally, in an interview with Wolf, we’re told:

Part of Wolf’s investigation revolves around the various hormones and neurotransmitters activated in a woman's body during a "successful" sexual encounter, eg dopamine, "which boosts the chemical construct of confidence, motivation, focus, all of these feminist qualities. Goal orientedness. Assertiveness"… In the book, she writes, "dopamine is the ultimate feminist chemical in the female brain,"

If that were true, women with Parkinson’s could never be feminists, because that disease is caused by degeneration of the dopamine neurons. If that were true, feminists would be campaigning for the legalization of cocaine and crystal meth – at least for women – because those drugs boost dopamine levels.

In fact, if that were true, it would mean that the most complimentary thing you could say to a woman would be “You sound like you’re on crack!”

Naomi Wolf, you sound like you’re on crack.

The decline of the north's sporting powerhouse

Yorkshire historically acted as a counterweight to the dominance of southern elites, in sport as in politics and culture. Now, things are different.

On a drive between Sheffield and Barnsley, I spotted a striking painting of the Kes poster. Billy Casper’s two-fingered salute covered the wall of a once-popular pub that is now boarded up.

It is almost 50 years since the late Barry Hines wrote A Kestrel for a Knave, the novel that inspired Ken Loach’s 1969 film, and it seems that the defiant, us-against-the-world, stick-it-to-the-man Yorkshireness he commemorated still resonates here. Almost two-thirds of the people of south Yorkshire voted to leave the EU, flicking two fingers up at what they saw as a London-based establishment, detached from life beyond the capital.

But whatever happened to Billy the unlikely lad, and the myriad other northern characters who were once the stars of stage and screen? Like the pitheads that dominated Casper’s tightly knit neighbourhood, they have disappeared from the landscape. The rot set in during the 1980s, when industries were destroyed and communities collapsed, a point eloquently made in Melvyn Bragg’s excellent radio series The Matter of the North.

Yorkshire historically acted as a counterweight to the dominance of southern elites, in sport as in politics and culture. Yet today, we rarely get to hear the voices of Barnsley, Sheffield, Doncaster and Rotherham. And the Yorkshire sporting powerhouse is no more – at least, not as we once knew it.

This should be a matter of national concern. The White Rose county is, after all, the home of the world’s oldest registered football club – Sheffield FC, formed in 1857 – and the first English team to win three successive League titles, Huddersfield Town, in the mid-1920s. Hull City are now Yorkshire’s lone representative in the Premier League.

Howard Wilkinson, the manager of Leeds United when they were crowned champions in 1992, the season before the Premier League was founded, lamented the passing of a less money-obsessed era. “My dad worked at Orgreave,” he said, “the scene of Mrs Thatcher’s greatest hour, bless her. You paid for putting an axe through what is a very strong culture of community and joint responsibility.”

The best-known scene in Loach’s film shows a football match in which Mr Sugden, the PE teacher, played by Brian Glover, comically assumes the role of Bobby Charlton. It was played out on the muddy school fields of Barnsley’s run-down Athersley estate. On a visit to his alma mater a few years ago, David Bradley, who played the scrawny 15-year-old Billy, showed me the goalposts that he had swung from as a reluctant goalkeeper. “You can still see the dint in the crossbar,” he said. When I spoke to him recently, Bradley enthused about his lifelong support for Barnsley FC. “But I’ve not been to the ground over the last season and a half,” he said. “I can’t afford it.”

Bradley is not alone. Many long-standing fans have been priced out. Barnsley is only a Championship side, but for their home encounter with Newcastle last October, their fans had to pay £30 for a ticket.

The English game is rooted in the northern, working-class communities that have borne the brunt of austerity over the past six years. The top leagues – like the EU – are perceived to be out of touch and skewed in favour of the moneyed elites.

Bradley, an ardent Remainer, despaired after the Brexit vote. “They did not know what they were doing. But I can understand why. There’s still a lot of neglect, a lot of deprivation in parts of Barnsley. They feel left behind because they have been left behind.”

It is true that there has been a feel-good factor in Yorkshire following the Rio Olympics; if the county were a country, it would have finished 17th in the international medals table. Yet while millions have been invested in “podium-level athletes”, in the team games that are most relevant to the lives of most Yorkshire folk – football, cricket and rugby league – there is a clear division between sport’s elites and its grass roots. While lucrative TV deals have enriched ruling bodies and top clubs, there has been a large decrease in the number of adults playing any sport in the four years since London staged the Games.

According to figures from Sport England, there are now 67,000 fewer people in Yorkshire involved in sport than there were in 2012. In Doncaster, to take a typical post-industrial White Rose town, there has been a 13 per cent drop in participation – compared with a 0.4 per cent decline nationally.

Attendances at rugby league, the region’s “national sport”, are falling. But cricket, in theory, is thriving, with Yorkshire winning the County Championship in 2014 and 2015. Yet Joe Root, the batsman and poster boy for this renaissance, plays far more games for his country than for his county and was rested from Yorkshire’s 2016 title decider against Middlesex.

“Root’s almost not a Yorkshire player nowadays,” said Stuart Rayner, whose book The War of the White Roses chronicles the club’s fortunes between 1968 and 1986. As a fan back then, I frequently watched Geoffrey Boycott and other local stars at Headingley. My favourite was the England bowler Chris Old, a gritty, defiant, unsung anti-hero in the Billy Casper mould.

When Old made his debut, 13 of the 17-strong Yorkshire squad were registered as working-class professionals. Half a century later, three of the five Yorkshiremen selec­ted for the last Ashes series – Root, Jonny Bairstow and Gary Ballance – were privately educated. “The game of cricket now is played in public schools,” Old told me. “Top players are getting huge amounts of money, but the grass-roots game doesn’t seem to have benefited in any way.”

“In ten years’ time you won’t get a Joe Root,” Rayner said. “If you haven’t seen these top Yorkshire cricketers playing in your backyard and you haven’t got Sky, it will be difficult to get the whole cricket bug. So where is the next generation of Roots going to come from?” Or the next generation of Jessica Ennis-Hills? Three years ago, the Sheffield stadium where she trained and first discovered athletics was closed after cuts to local services.
