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 buck doesn't stop with Grant Shapps - and probably shouldn't stop with Lord Feldman, either

The question of "who knew what, and when?" shouldn't stop with the Conservative peer.

If Grant Shapps’ enforced resignation as a minister was intended to draw a line under the Mark Clarke affair, it has had the reverse effect. Attention is now shifting to Lord Feldman, who was joint chair during Shapps’  tenure at the top of CCHQ.  It is not just the allegations of sexual harrassment, bullying, and extortion against Mark Clarke, but the question of who knew what, and when.

Although Shapps’ resignation letter says that “the buck” stops with him, his allies are privately furious at his de facto sacking, and they are pointing the finger at Feldman. They point out that not only was Feldman the senior partner on paper, but when the rewards for the unexpected election victory were handed out, it was Feldman who was held up as the key man, while Shapps was given what they see as a relatively lowly position in the Department for International Development.  Yet Feldman is still in post while Shapps was effectively forced out by David Cameron. Once again, says one, “the PM’s mates are protected, the rest of us shafted”.

As Simon Walters reports in this morning’s Mail on Sunday, the focus is turning onto Feldman, while Paul Goodman, the editor of the influential grassroots website ConservativeHome has piled further pressure on the peer by calling for him to go.

But even Feldman’s resignation is unlikely to be the end of the matter. Although the scope of the allegations against Clarke were unknown to many, questions about his behaviour were widespread, and fears about the conduct of elections in the party’s youth wing are also longstanding. Shortly after the 2010 election, Conservative student activists told me they’d cheered when Sadiq Khan defeated Clarke in Tooting, while a group of Conservative staffers were said to be part of the “Six per cent club” – they wanted a swing big enough for a Tory majority, but too small for Clarke to win his seat. The viciousness of Conservative Future’s internal elections is sufficiently well-known, meanwhile, to be a repeated refrain among defenders of the notoriously opaque democratic process in Labour Students, with supporters of a one member one vote system asked if they would risk elections as vicious as those in their Tory equivalent.

Just as it seems unlikely that Feldman remained ignorant of allegations against Clarke if Shapps knew, it feels untenable to argue that Clarke’s defeat could be cheered by both student Conservatives and Tory staffers and the unpleasantness of the party’s internal election sufficiently well-known by its opponents, without coming across the desk of Conservative politicians above even the chair of CCHQ’s paygrade.
