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.

Rarely has it mattered so little if Manchester United won; rarely has it been so special they did

Team's Europa League victory offers chance for sorely needed celebration of a city's spirit.

Carlo Ancelotti, the Bayern Munich manager, memorably once said that football is “the most important of the least important things”, but he was only partly right. While it is absolutely the case that a bunch of people chasing around a field is insignificant, a bunch of people chasing around a field is not really what football is about.

At a football match can you set aside the strictures that govern real life and freely scream, shout and cuddle strangers. Football tracks life with such unfailing omnipresence, garnishing the mundane with regular doses of drama and suspense; football is amazing, and even when it isn’t there’s always the possibility that it’s about to be.

Football bestows primal paroxysms of intense, transcendent ecstasy, shared both with people who mean everything and people who mean nothing. Football carves out time for people it's important to see and delivers people it becomes important to see. Football is a structure with folklore, mythology, language and symbols; being part of football is being part of something big, special, and eternal. Football is the best thing in the world when things go well, and still the best thing in the world when they don’t. There is nothing remotely like it. Nothing.

Football is about community and identity, friends and family; football is about expression and abandon, laughter and song; football is about love and pride. Football is about all the beauty in the world.

And the world is a beautiful place, even though it doesn’t always seem that way – now especially. But in the horror of terror we’ve seen amazing kindness, uplifting unity and awesome dignity which is the absolute point of everything.

In Stockholm last night, 50,000 or so people gathered for a football match, trying to find a way of celebrating all of these things. Around town before the game the atmosphere was not as boisterous as usual, but in the ground the old conviction gradually returned. The PA played Bob Marley’s Three Little Birds, an Ajax staple with lyrics not entirely appropriate: there is plenty about which to worry, and for some every little thing is never going to be alright.

But somehow the sentiment felt right and the Mancunian contingent joined in with gusto, following it up with “We’ll never die,” – a song of defiance born from the ashes of the Munich air disaster and generally aired at the end of games, often when defeat is imminent. Last night it was needed from the outset, though this time its final line – “we’ll keep the red flag flying high, coz Man United will never die" – was not about a football team but a city, a spirit, and a way of life. 

Over the course of the night, every burst of song and even the minute's silence chorused with that theme: “Manchester, Manchester, Manchester”; “Manchester la la la”; “Oh Manchester is wonderful”. Sparse and simple words, layered and complex meanings.

The match itself was a curious affair. Rarely has it mattered so little whether or not United won; rarely has it been so special that they did. Manchester United do not represent or appeal to everyone in Manchester but they epitomise a similar brilliance to Manchester, brilliance which they take to the world. Brilliance like youthfulness, toughness, swagger and zest; brilliance which has been to the fore these last three days, despite it all.

Last night they drew upon their most prosaic aspects, outfighting and outrunning a willing but callow opponent to win the only trophy to have eluded them. They did not make things better, but they did bring happiness and positivity at a time when happiness and positivity needed to be brought; football is not “the most important of the least important things,” it is the least important of the most important things.
