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.

After so badly misjudging the leadership contest, how will the Blairites handle Corbyn?

The left-winger's opponents are divided between conciliation and aggression. 

When Labour lost the general election in May, the party’s modernisers sensed an opportunity. Ed Miliband, one of the most left-wing members of the shadow cabinet, had been unambiguously rejected and the Tories had achieved their first majority in 23 years. More than any other section of the party, the Blairites could claim to have foreseen such an outcome. Surely the pendulum would swing their way?

Yet now, as Labour’s leadership contest reaches its denouement, those on the right are asking themselves how they misjudged the landscape so badly. Their chosen candidate, Liz Kendall, is expected to finish a poor fourth and the party is poised to elect Jeremy Corbyn, the most left-wing leader in its 115-year history. For a faction that never ceases to underline the importance of winning elections, it will be a humbling result.

Though the crash has been sudden, the Blairites have long been in decline. Gordon Brown won the leadership unchallenged and senior figures such as John Reid, James Purnell and Alan Milburn chose to depart from the stage rather than fight on. In 2010, David Miliband, the front-runner in the leadership election, lost to his brother after stubbornly refusing to distance himself from the Iraq war and alienating undecided MPs with his imperiousness.

When the younger Miliband lost, the modernisers moved fast – too fast. “They’re behaving like family members taking jewellery off a corpse,” a rival campaign source told me on 9 May. Many Labour supporters agreed. The rush of op-eds and media interviews antagonised a membership that wanted to grieve in peace. The modernising contenders – Chuka Umunna, Liz Kendall, Mary Creagh, Tristram Hunt – gave the impression that the Blairites wanted to drown out all other voices. “It was a huge mistake for so many players from that wing of the party to be put into the field,” a shadow cabinet minister told me. “In 1994, forces from the soft left to the modernising right united around Tony Blair. The lesson is never again can we have multiple candidates.”

While conducting their post-mortem, the Blairites are grappling with the question of how to handle Corbyn. For some, the answer is simple. “There shouldn’t be an accommodation with Corbyn,” John McTernan, Blair’s former director of political operations, told me. “Corbyn is a disaster and he should be allowed to be his own disaster.” But most now adopt a more conciliatory tone. John Woodcock, the chair of Progress, told me: “If he wins, he will be the democratically elected leader and I don’t think there will be any serious attempt to actually depose him or to make it impossible for him to lead.”

Umunna, who earlier rebuked his party for “behaving like a petulant child”, has emphasised that MPs “must accept the result of our contest when it comes and support our new leader in developing an agenda that can return Labour to office”. The shadow business secretary even suggests that he would be prepared to discuss serving in Corbyn’s shadow cabinet if he changed his stances on issues such as nuclear disarmament, Nato, the EU and taxation. Were Umunna, a former leadership contender, to adopt a policy of aggression, he would risk being blamed should Corbyn fail.

Suggestions that the new parliamentary group Labour for the Common Good represents “the resistance” are therefore derided by those close to it. The organisation, which was launched by Umunna and Hunt before Corbyn’s surge, is aimed instead at ensuring the intellectual renewal that modernisers acknowledge has been absent since 2007. It will also try to unite the party’s disparate mainstream factions: the Blairites, the Brownites, the soft left, the old right and Blue Labour. The ascent of Corbyn, who has the declared support of just 15 MPs (6.5 per cent of the party), has persuaded many that they cannot afford the narcissism of small differences. “We need to start working together and not knocking lumps out of each other,” Woodcock says. There will be no defections, no SDP Mk II. “Jeremy’s supporters really underestimate how Labour to the core the modernisers are,” Pat McFadden, the shadow Europe minister, told me.

Although they will not change their party, the Blairites are also not prepared to change their views. “Those of us on this side of Labour are always accused of being willing to sell out for power,” a senior moderniser told me. “Well, we do have political principles and they’re not up for bartering.” He continued: “Jeremy Corbyn is not a moderate . . .
He’s an unreconstructed Bennite who regards the British army as morally equivalent to the IRA. I’m not working with that.”

Most MPs believe that Corbyn will fail but they are divided on when. McFadden has predicted that the left-winger “may even get a poll bounce in the short term, because he’s new and thinking differently”. A member of the shadow cabinet suggested that Labour could eventually fall to as low as 15 per cent in the polls and lose hundreds of councillors.

The challenge for the Blairites is to reboot themselves in time to appear to be an attractive alternative if and when Corbyn falters. Some draw hope from the performance of Tessa Jowell, who they still believe will win the London mayoral selection. “I’ve spoken to people who are voting enthusiastically both for Jeremy and for Tessa,” Wes Streeting, the newly elected MP for Ilford North, said. “They have both run very optimistic, hopeful, positive campaigns.”

But if Corbyn falls, it does not follow that the modernisers will rise. “The question is: how do we stop it happening again if he does go?” a senior frontbencher said. “He’s got no interest or incentive to change the voting method. We could lose nurse and end up with something worse.” If the road back to power is long for Labour, it is longest of all for the Blairites.
