Monthly Links

WTF happened there? Where has this year gone? It’s already the end of November and we’re deep into SAD season. But let’s not despair ‘cos here’s our monthly selection of links to items you might have missed the first time round.

Science, Technology & Natural World

If you’re an AI designer the Law of Unintended Consequences is never far away. Such systems are well known for gaming the system with a solution that satisfies the stated objective but fails to solve the problem according to the human designer’s intent. There’ll be some examples at the end of this post.

A violent storm on the Sun could cripple communications on Earth and cause huge economic damage, but why are solar storms such a threat?

Health & Medicine

Here are six surprising drug interactions which often fly under the radar but which you should know about. Even I knew about only two of them.

This one is definitely straight out of the “I Don’t Believe It” drawer … apparently llama blood may provide clues to beating the flu.

Researchers at the University of Portsmouth are investigating how the proportion of fat and glandular tissue affects the perkiness of boobs, and why one bra design doesn’t fit all.

Our favourite OB/GYN, Dr Jen Gunter, takes a look at the menopause, and her personal experience in deciding how to manage it.

GPs in England are being encouraged to prescribe social activities to their patients as part of the government’s strategy to combat loneliness. But this is raising some ethical questions: are the consequences acceptable and does the initiative respect people as people?

As so often, the ancient Chinese had an inventive way of doing things: pay your doctor as long as you’re healthy; when you’re sick they’ve failed and don’t get paid.

Sexuality

Here’s one good example of why we must not be too scared to talk about teenagers having sex.

Labour MP Jess Phillips is campaigning to ensure girls are taught about their sexuality from a young age so they form healthy sexual relationships as adults and not just “how to handle and dispose of men’s pleasure safely”. Read her views here and here.

On the other side of the coin, a survey confirms that stress damages many people’s sex lives.

So now relax ‘cos you’re unlikely to be masturbating too much.

Environment

Scientific American looks at why we really do need innovative nuclear power.

History, Archaeology & Anthropology

Researchers have been taking an in depth look at Neanderthal teeth, and discovering some surprisingly intimate details of their daily life.

Meanwhile others have been dating the oldest known animal painting which has been found in a cave in Borneo. I’m glad they know it’s an animal.

Still with animals but much closer to home, archaeologists at the Vindolanda fort have uncovered a Roman dog with fur intact. Well they say it’s Roman, but they also say it is 2000 years old: both cannot be true!

Yet another group, this time at the British Museum, have been delving into Egyptian fashion and examining a 1700-year-old child’s left sock.

Since Ancient Roman times, and right up to Hollywood, witches have been seen as figures of fun as well as malevolence.

From at least 1000 years ago the Peruvians were into making holes in their heads.

Finally in this section, and coming almost up to date, a dredging project at Blenheim Palace has uncovered over 30 rooms flooded when Capability Brown created the estates lakes.

Food & Drink

The Marine Conservation Society has been looking at the humble fish finger and found that they are surprisingly sustainable and some of the best products to buy are also the cheapest.

Shock, Horror, Humour

Finally, we promised some more on the unintended consequences of AI. There are quite a few examples in a Google document, including these two:

A self-driving car which was rewarded for speed learnt to spin in circles.

In an artificial life simulation where survival required energy but giving birth had no energy cost, one species evolved a sedentary lifestyle that consisted mostly of mating in order to produce new children which could be eaten (or used as mates to produce more edible children).

Remember: If a system can be gamed, someone or something will game it.

Enjoy your Christmas turkey!

Teenagers and Sex

Three (I think) important articles recently about teenagers and sex. As usual we bring you key quotes, although I would recommend reading the articles themselves (none is long).

The first article reports on Labour MP Jess Phillips’ contention that the discussion of female pleasure is essential to redress the gender power imbalance.

Teach schoolgirls about orgasms (Guardian; 8 November 2018)

Schoolgirls should be taught about orgasms in sex education lesson … girls should be taught about sex from a young age in order to form healthy sexual relationships when they become adults.

[It is] vital to discuss female pleasure in order to “break down the culture of power imbalance between men and women” …

“I’m not suggesting we teach children how to masturbate, I’m suggesting we talk to them about the things they’re doing anyway.”

Women’s expectations “should be greater” and they should “start demanding more” during sex.

“I’ve made a career out of being able to talk about difficult things, and that comes from growing up in an environment where nothing was embarrassing.”

Phillips is campaigning for sex education in [all] secondary schools to be compulsory by 2020 … [E]ducating children about healthy relationships and their anatomy will reduce the risk of violence against women: “To liberate women and end violence is to break down the culture of power imbalance. Let’s stop people feeling ashamed.”

The second article is by Jess Phillips herself.

Yes, yes, yes: why female pleasure must be at the heart of sex education (Guardian; 13 November 2018)

By the time they started talking to us about [sex] at secondary school, I think in the third year (year 9), most of the girls in my class had had their first sexual encounters … The teachers were clearly counting on us not having had intercourse (although some of us had) because our sex education was about Aids … and babies. It was essentially a lesson in contraception.

Sex and relationships were never discussed in our contraceptive education. It was all about the dangers of a man climaxing … We were shown how to handle and dispose of men’s pleasure safely.

[T]he average member of the British public thinks men need sex more than women … This is a cultural norm we have all accepted and it seeps into how we live our lives and teach our children. Men don’t need sex any more than women, they just enjoy it more because it has a guaranteed payoff.

“Just say no” doesn’t work, so perhaps we need to try teaching young people about why they might want to say “yes”. What does good, healthy and happy sex look like, for example?

Girls masturbate, girls know all about what they like and want. They also know what boys like and want. Boys only know the latter. Girls and boys spend at least the first 10 years of their sex lives focusing exclusively on what boys want … Would it hurt to talk to both boys and girls about how sex should be for both parties? Giving girls a bit of hope that shagging won’t just lead to them dripping in breast milk or being a witness in a trial.

I don’t want young girls growing up thinking that sex is just something that happens to us. I want boys and girls to know that it should be about both people not just agreeing, but also enjoying it.

The third article is from a young Nigerian, Jennifer Amadi, who lost a close friend to a DIY abortion because everyone had been too scared to talk to teenagers about sex.

The world must not be too scared to talk about teenagers having sex (Guardian; 9 November 2018)

[T]the world is too scared to talk about teenagers having sex. And young people are losing their lives and livelihoods as a result.

I see these attitudes everywhere, from Nigeria to the UK. Parents who are too uncomfortable to have “the talk” with their kids, nurses who deny young girls contraceptives because they think they’re “too young to have sex”, education ministers who believe the best policy for addressing teenage pregnancies is a sound beating paired with expulsion rather than comprehensive sex education classes.

[P]oliticians … worry that supporting programmes that increase youth access to contraception will cost them their jobs … fearful leaders … earmark foreign aid for politically safe initiatives like abstinence-based sex-ed or programmes that only provide birth control to married women.

There are 1.2 billion people in the world between the ages of 10 to 19 and most live in developing countries …

[W]here the world fails to deliver for its young people … teenagers continue to have unintended pregnancies. Millions of girls experience health issues stemming from pregnancy and childbirth their bodies aren’t ready for, and efforts to improve gender equality are upended as teenage mothers are forced to drop out of school and face lifelong economic insecurity … this has the potential to put the economic and social progress of entire countries at risk, and has lasting implications for global trade, migration and foreign affairs.

[I]nvest in our young people so they can get reliable information about reproductive health and birth control. They decide when to have children and how many to have. They become the biggest generation of educated, empowered, working adults the world has seen. They break the cycle of poverty for their families and shape the future of their countries.

As I keep saying, time to wake up and smell the coffee. With the UK government currently looking at reforming sex education in the classroom this country has the opportunity to lead the world. But it needs imagination and bravery, something for which the UK government has never been noted.

Womanhood: The Bare Reality

Laura Dodsworth, author of Manhood: The Bare Reality has a new book coming out, but unfortunately not until next February.

Its title: Womanhood: The Bare Reality.

You can, of course, pre-order it on Amazon or from the publishers Pinter & Martin.

The book promises to do for women, what Manhood did for men: tell of the variety and the stories of man and manhood. As the blurb an Amazon says:

100 women bare all in an empowering collection of photographs and interviews about Womanhood.

Vagina, vulva, lady garden, pussy, beaver, c**t, fanny … whatever you call it most women have no idea what’s ‘down there’. Culturally and personally, no body part inspires love and hate, fear and lust, worship and desecration in the same way.

From smooth Barbie dolls to internet porn, girls and women grow up with a very narrow view of what they should look like, even though in reality there is an enormous range. Womanhood departs from the ‘ideal vagina’ and presents the gentle un-airbrushed truth, allowing us to understand and celebrate our diversity.

For the first time, 100 brave and beautiful women reveal their bodies and stories on their own terms, talking about how they feel about pleasure, sex, pain, trauma, birth, motherhood, menstruation, menopause, gender, sexuality and simply being a woman.

Laura comments further in a recent Facebook post:

“A major issue for women is that men and society are really interested in defining womanhood for us and without us. A lot of the time, women don’t have an awful lot of input into the definition of womanhood, yet we’re judged against it. Women have to make choices that men don’t ever have to make.”
From Womanhood: The Bare Reality

A bold first quote to share from Womanhood. I’ve already been #notallmen-ed on Twitter, so let me say, I love men, this is not anti-men. (I LOVE men.) Remember Manhood?

But this is the point; Womanhood is an exploration of female experience through the embodied stories of 100 women. We define Womanhood on our own terms and in our own words. We reveal ourselves to ourselves and to each other. And it’s about time.

Laura’s previous books (Manhood: The Bare Reality and Bare Reality: 100 Women, Their Breasts, Their Stories) were amazing, revealing and informative, so I’m really am looking forward to reading Womanhood: The Bare Reality. My copy is already on order.

Full disclosure: I was one of the 100 men featured in Manhood.

Life Drawing

Thanks to @ldsdrawingclub on Twitter for drawing attention to this piece from the Daily Telegraph of a few days ago.

Life drawing can help teens overcome
social media body confidence issues

The Telegraph website is paywalled, so here are a few snippets:

Experts including the former president of the Royal Society of Portrait Painters have advised that drawing nude models could help youngsters understand what “real” people look like, compared to those on social media.

What is out there online for youngsters is often superficial and does not accurately represent what people look like in real life … images seen online and on social media are having an impact of distorting reality and … cause people to have body confidence issues or think how they look is different.

I would urge people to get involved in life drawing which has the benefit of allowing people to question what the ‘ideal’ body is.

Life drawing is an opportunity to study the human form, folds, blemishes and all – not wondering if the image you’re obsessing over has been photoshopped.

Those who follow along here won’t be surprised to learn that I entirely agree. I can’t draw for toffee – I was so bad I wasn’t allowed to take O-level Art at school, but I have been to an art class since school (to little effect, I may say). But in many ways one’s drawing ability doesn’t matter. What’s important is the exposure, the ability to see so many different forms, the opportunity through drawing to see how all the pieces and shapes fit together, and to realise it is all normal.

More power to these people for doing their bit to cure us of this toxic ethos and these ridiculous taboos.

Who’s Day

Today (2 June) is International Whores’ Day, aka. International Sex Workers’ Day.

As regular readers will know, and you don’t have to look too far back in the archives to find out, I am a firm believer that sex work should be decriminalised. I’ve never used the services of a sex worker, and I have no plans to do so, but I fail to see why people should not be able to pay for sex, or to sell sex, if that is their choice.

Prostitutes (of all types) perform a valuable social service. In part they may be considered part of the leisure industry, providing what might be called “alternative entertainment”. But they also provide service for many who would not otherwise have sex, or have the sex they want, and that can be a significant factor in preserving mental health.

Fortunately there does seem to be a growing body of academically rigorous evidence that decriminalisation is the best way to protect the human rights of sex workers, and ensure they can follow their chosen profession in safety, with unobstructed access to legal recourse where there is violence or abuse. New Zealand has shown the way on this, as have the World Health Organization and Amnesty International.

I don’t want to have to write at length about all the reasoning, so here are just a few relatively recent reports of some of this research.

Decriminalising sex work is the only way to protect women – and New Zealand has proved that it works; Independent; 29 May 2017

Decriminalising prostitution could ‘dramatically’ reduce sexual violence and STI transmission; Independent; 20 December 2017

Decriminalising Sex Work Is Better for Everyone; Big Think; 12 December 2017

Amnesty International policy on state obligations to respect, protect and fulfil the human rights of sex workers; Amnesty International; 26 May 2016

Decriminalising sex work in New Zealand: its history and impact; Open Democracy; 21 August 2015

I don’t understand why prostitution is illegal. Selling is legal. Fucking is legal. Why isn’t selling fucking legal? You know, why should it be illegal to sell something that’s perfectly legal to give away?
– George Carlin

Why is the decision by a woman to sleep with a man she has just met in a bar a private one, and the decision to sleep with the same man for $100 subject to criminal penalties?
– Anna Quindlen

Monthly Interesting Links

As regular readers will realise, I read a lot of articles in consumer science, consumer history and the more general media over the course of a month – articles which look as if they will interest me. (I don’t generally read politics, business etc.). What I post here are only those items which I think may be of more general interest to you, my readers, being mindful that the humanities people amongst you might want a bit of “soft” science; and the scientists a bit of humanities. So I do try to mostly avoid difficult science and academically dense Eng.Lit. or history – ‘cos you don’t all want to struggle with/be interested in that, though some may. And I obviously don’t expect everyone to read everything, but just to pick the items which interest you most; if you find one or two each month then that’s good.

So, having restated my aims for this series, let’s get down to business – because there is a lot to cover this month.

Science, Technology & Natural World

We start off with something which surprised me: the engineers building Crossrail had to take the curvature of the Earth into account, because of the length of the line and the precision with which some of the tunnels had to be threaded through between existing structures.

Staying on an engineering theme, scientists have developed a method of making wood as strong as steel, and thus potentially useable as a high strength building material.

Changing themes, what really is biodiversity and why is it so important?

The curious history of horses’ hooves, and how five digits became just one.

Following the attack on a pair of Russians in Salisbury, several of the scientific media have been asking what nerve agents are and how they work. This is Scientific American‘s view.

Health & Medicine

A strange, six inch long, “mummy” was found in Chile some years ago, and many people decided it was an alien – hardly surprising given its appearance. However, following DNA testing it has finally been confirmed that it was a very deformed, female, human infant.

Musician Taylor Muhl has a large birthmark on her torso, but it turns out that it isn’t a birthmark but that she’s a chimera, having absorbed a twin sister in utero in the very early days of gestation.

Influenza is relatively common, and benign, in may non-primate species which provide a natural reservoir for the virus. And there are many other such viruses out in the wild which are a concern as (like Ebola, Zika, SARS) they could mutate and jump to humans.

On a similar theme, researchers are coming to realise that there is a genetic component to our susceptibility to many diseases and that disease prevalence partly depends on the genetic mutations we carry.

Sexuality

From consent advice to sex toys and masturbation hacks, YouTube has taken over sex education.

Language

While on sex, the Whores of Yore website has a history of Cunt, the word.

History, Archaeology & Anthropology

Researchers have analysed a huge number of DNA samples to discover that Homo sapiens interbred with Denisovans on multiple occasions, as we did with the Neanderthals.

Why did Oxford and Cambridge have a monopoly on UK university education for several hundred years, when universities proliferated across the rest of Europe?

Long before the height of the slave trade and the British Empire, black Africans lived freely in Tudor England.

In 1600 Giordano Bruno burned at the stake as a heretic and it looks likely that this was for believing in the existence of planets outside our solar system.

The oldest message in a bottle has been found on a beach in Western Australia.

London

Mudlarking: the pursuit of archaeological treasures hiding in the mud of the River Thames foreshore. Warning: you need a licence!

John Joseph Merlin, a wizard in Georgian London.

Lifestyle & Personal Development

Brad Warner, one of our two favourite Zen Masters, on waking up happy.

So just how many beak-ups does one have to have before one finds “the one”? Search me!

The exorcists are coming, and it doesn’t look good.

We’re living through a crisis of touch where lots of basic human contact like hugging is no longer acceptable – and it is having a serious effect on our mental health.

OK guys, this is for you: 100 easy ways to make women’s lives better. Basically: be considerate!

Finally, following on from the above two items, an article I found rather nauseating about the supposed crisis in modern masculinity. Gawdelpus all!

More next month! Meanwhile, be good!

How to Be a Better Spouse

For Valentine’s Day, yesterday, Scientific American posted an article entitled How to Be a Better Spouse. You can read the detail in the article, but the four headline tips are:

  1. Be nice as often as you can
  2. Think about what your partner needs, even when fighting
  3. Just notice them
  4. Ignore the bad, praise the good

Yes, well, they’re sort of obvious really. But do we do this? Well, not as much as we probably should – I certainly don’t despite 38 years married (eeeekk!!!!), although I must be doing something not too wrong.
But then do these all not amount to the old adage: Communicate, communicate, communicate?
And think on this too … Are these ideas not things we should be doing to everyone, and not just our partners? Do they not all fall under the umbrella of Treat others as you would wish them to treat you? Reductio ad adsurdum.
On the other hand we do have to have these things pointed out to us occasionally so we don’t forget them.

Your Interesting Links

This month’s large collection of articles encountered which you maybe didn’t want to have missed.
Science & Natural World
First off we must pay our respects to this year’s IgNobel award winners amongst whose investigations were solid and liquid cats, didgeridoos and cheese disgust.
Budburst on many trees is temperature dependent and March temperatures seem to be the key for many. And they’re getting slowly warmer, so budburst is getting earlier.
[Disclosure: I’ve been submitting records to UK phenology research for many years; many more years that the 17 covered by this research. It takes little time and is valuable “citizen science”.]


Another curiosity of British wildlife is that some birds (notably Great Tits, above) are evolving longer beaks as this gives them an advantage at garden bird feeders. Here are two complementary reports, one from the Guardian, the other from the BBC.
Now to chemistry … A look at how poisoners could use clothing as a murder weapon.
The aliens are coming! Well maybe not quite, but there is a mysterious object speeding past the sun which could be visitor from another star system.
Health & Medicine
For those who want a little more of a challenge than normal (it contains some relatively simple maths), here’s a very good article on why vaccination is important in preventing epidemics.
Sepsis is a hidden killer, and one which most people know nothing about because it has so successfully continued flying under our radar.
There’s a small study which suggests that the psychoactive drugs in magic mushrooms “reset” the brains of depressed people. [Do NOT try this at home! The study used very controlled doses in a medical environment.]
And now to some curiosities … First off, and not for the squeamish, an historical report of a man with two penises and two bladders.
Synaesthesia is mind-boggling. The first of our two mentions this month is of a woman who lost her sight due to illness and in regaining it had some terrifying sounding synaesthetic effects.
And to boggle the mind even further, this young lady has a range of different types of synaesthesia (compared with the normal one). I just cannot imagine what this is like!
Sexuality
Two different aspects of a relationship without sex. First there are people who are genuinely asexual: they may have romantic partnerships but have no interest or desire to have sex.
At almost the other extreme there are couples who, while still happy together, just stop having sex.
Social Sciences, Business, Law
Forensic science is coming under increasing scrutiny. Not only has fingerprinting never been scientifically evaluated for its reliability, but DNA is accused of frequent flawed techniques, which can have devastating effects.
Language
Philip Pullman is under fire because his children’s book La Belle Sauvage is littered with swearwords. Emma Byrne in the Guardian suggests this is actually a good thing: most children already know the words and isn’t it better that they learn in a controlled way when they are and are not acceptable?
History, Archaeology & Anthropology
Uncovering the menus for Neolithic man’s feasts: pork and cheese.
The Incas were far better astronomers than previously thought.
The shipwreck which produced the Antikythera mechanism is still turning up interesting artefacts like the bronze arm which suggests there may be a haul of statues waiting to be found – and what may be another piece of the Antikythera mechanism itself.
Why do a number of Scandinavian Viking graves contain burial clothing embroidered with the work “Allah”
But worse is yet to come, for the Vikings may have brought leprosy to this country via their trade in red squirrels.
Coming much more up to date, both sides are now telling the story of the capture and boarding of the German U-boat U-559, which changed WWII by giving the Allies the Germans’ Enigma codes.
So how about a list of the ten best railway stations in Britain, at least according to Simon Jenkins in the Guardian.
London
IanVisits is writing an occasional series on “Unbuilt London”. In an old post he looks at the 1960s plan to replace buses with monorail network. I have a vague memory of this hare-brained scheme.
And here is a really fascinating and detailed map of the London Underground, Overground, DLR, Tramlink & National Rail (small section below). But why does this have to be published by a French company?

Lifestyle & Personal Development
Our favourite Soto Zen master, Brad Warner, reflects on “The Center of All That” the implications of being you, here.
We’re losing our skills. The skills to do everyday chores our parents took for granted, like washing up by hand, changing a mains fuse or sewing on a button.
A brief look at some of what happens behind the doors of a London crematorium.
I wasn’t sure whether to put this next item here or under medicine. According to sleep scientists we are chronically underslept and sleepwalking our way through life. That is a real threat to our health, and it isn’t fixed by a couple of good lie-ins. So what to do about it?
Apparently our culture says that emotional friendships are a female thing and that boys cannot have emotional friendships with their own sex and are discouraged from doing so by the time they hit puberty. And this is forcing a large number of men into loneliness despite the outward appearances. [OK, it’s American, but is UK culture so different?]
People

Back in August Geoff Marshall (no relation)and Vicki Pipe completed their challenge to visit all 2,563 National Rail stations in Great Britain. Here they talk about the experience for the National Railway Museum’s blog.
That’s all folks! Another instalment next month.

Book Review: Ethical Porn for Dicks

David J Ley
Ethical Porn for Dicks: A Man’s Guide to Responsible Viewing Pleasure

ThreeL Media, USA; 2016
Do you watch porn? If you’re male there’s a very high chance that you have at sometime in your life, even if you don’t now. If you’re female the chances are still good that you have done.
Do you believe that porn is bad for you? That it incites sexual abuse and violence? That all the performers are doing it because of exploitation, their working practices are unsafe and they have no control?
Do you feel shame because you, or your partner, watch porn?
If the answer to any of these questions is “yes”, then this book is for you. OK it is American and is aimed directly at men, but in my view it is relevant for everyone from mid-teens upwards, and whatever their gender and sexual orientation.
Our media are filled with cautionary, polarizing messages about the dangers of porn, even while sexually explicit images are exploited deliberately and persuasively in adverts and entertainment. This book offers anyone feeling shame and anxiety about their own, or their partner’s, behaviour a non-judgmental way to view and use pornography responsibly, while exploding many of the surrounding myths.
Ley is an expert on issues relating to sexuality, pornography and mental health. As a practising psychologist he is the head of a large behavioural health and substance abuse out-patient programme. Consequently he is able to bring years of first-hand experience, and academic credibility, to understanding what the problems of pornography are, and aren’t.
The book’s style is casual and accessible while remaining evidence-based – it isn’t littered with footnotes, but all the referenced texts are listed in the bibliography. Because it is broken down into about ten chapters, each consisting of several discrete sections, posed as questions, it can either be read cover-to-cover (as I did) or can sensibly be dipped into.
Just two quotes from the book …

Porn, for better or worse, is here to stay. In the US, it is protected under free speech, and it needs to be because if we lose the right of free sexual expression, we lose many other critical protections. Porn, as illustrated by … cave drawings … has been around as long as humanity. Attempts to get rid of porn are just more likely to drive it underground, where it is secret and hidden. And under such secrecy, people are more likely to get hurt or taken advantage of, and lose the ability to freely consent.

Rates of sexual offending go down as people in a society have more access to pornography. This is research that has been replicated in the United States and around the world. People don’t talk about this because they don’t want to acknowledge what it means. Porn is good for society. A society with more access to porn is a sexually safer society. Access to pornography may decrease rates of juvenile sex offending even more. If pornography were a moral-altering thing, turning weak-minded people into rapists and paedophiles, it would have a greater negative effect on teen boys. And it doesn’t. Just the opposite. Gay men watch more porn than straight men. But rates of rape and sexual violence in gay men are lower than in heterosexuals.

These are two of the key messages from the book. But there are two more which struck me:
First … We need to keep firmly in mind that porn is fantasy, in just the same way that Terry Pratchett and Disney are fantasy. It isn’t real life and we shouldn’t treat it as such. Just as real life isn’t filled with giants, battles and fairy princesses the way fantasy novels/films are, so real life sex isn’t (certainly shouldn’t be) violent, abusive and non-consensual. Porn may portray these traits as part of their fantasy fiction (and indeed many have them as mental fantasies) but neither is real life, properly adjusted, sex. We need to help people, especially the younger generations, understand this.
Secondly … If you worry about the exploitation aspects of porn then there are many producers who create ethical porn – the performers are well paid, their health is looked after, their working practices are safe and they have control over what is, and is not, permissible – then this book references several of these together with a long list of resources at the end.
Having said all that I did find the book rather too easy-reading; I wanted some more meat – but that’s me with my scientific background. Overall, if porn is a subject which interests you, or on which you feel you need more knowledge to help inform your children, then you could do much worse than read this book.
Overall Rating: ★★★★☆

Book Review: The Sex Myth

Brooke Magnanti
The Sex Myth: Why Everything We’re Told is Wrong
Weidenfeld & Nicolson; 2012
If, like me, you’re always doubtful of what “they” are telling us about sex (well actually about anything) then this book is an eye-opener. And who better to open our eyes than Brooke Magnanti, for if anyone knows then she should:

Brooke Magnanti studied Genetic Epidemiology and gained her PhD at the Department of Forensic Pathology, University of Sheffield. Her professional interests include population-based research, standards of evidence, and human biology and anthropology. In 2009 it was revealed that she is an ex-call girl and author of the bestselling Belle de Jour series of memoirs, which were adapted into the TV series, Secret Diary of a Call Girl.

She is also a novelist, blogger and activist who, in 2016, was called to give evidence about sex work conditions in the UK to the Home Affairs Committee investigating prostitution laws in Britain.
In describing the content I can’t do a lot better than the book’s cover blurb:

Is there any truth to the epidemic of sex addiction? Are our children really getting sexualised younger? Are men the only ones who like porn? Brooke Magnanti looks at all these questions and more – and proves that perhaps we’ve all been taking the answers for granted.
Brooke Magnanti is no stranger to controversy. As Belle de Jour she enthralled and outraged the nation … Now her real identity is out in the open, Brooke’s background as a scientist and a researcher comes to bear in this fascinating investigation into the truth behind the headlines, scandals and moral outrage that fill the media (and our minds) when it comes to sex.
… Brooke strips away the hype and looks at the science behind sex and the panic behind public policy. Unlike so many media column inches, Brooke uses verifiable academic research. This is fact, not fiction; science not supposition.

Don’t let the “science” label put you off. Yes, Brooke references all her sources but her style is light and eminently readable. She combines her skills in statistics, epidemiology and research with her experiences as a call-girl to blow the lid off what the Agenda Setters and politicians are telling us, thus exposing all the myths surrounding sex in society.
Brooke follows what the Agenda Setters and Evangelisers are saying and traces back where they get (or more usually fabricate) their data – and then by reference to peer-reviewed research shows where and how it is false. From sex addiction, through trafficking for sex, to the decriminalisation of prostitution, myths are well and truly busted.
If I had to find criticisms of the book they would be four, albeit relatively small: (1) It’s a shame the book is now 5 years old; it would be good to have an update. (2) Personally I would have liked more diagrammatic explanations of the data presented. (3) In each chapter a summary of the evidence, and how it is built into the arguments, would have helped my understanding of the (often necessarily) convoluted and detailed analysis. And (4) like so many books these days it could well be reduced in size by better design and typography and not printed on such cheap paper.
But that aside, the book is highly illuminating and well worth reading.
Overall Rating: ★★★★☆
