Homosexuality, Post 4: The Science

Biological and Psychological Factors

Defining the Different Dimensions of the Debate on the ‘Causes’ of Homosexuality:

The debate is a complex one.  On the one hand there is the ‘nature/nurture’ debate as to the causes of homosexuality.  Then on the other hand there is the essentialist/constructionist debate.  People from a range of perspectives are found on all sides of the debate.

The ‘nature / nurture’ debate is simply the question as to whether homosexuality is something that people are born with, or whether it is something they learn from their environment.  Most people think that both nature and nurture play a significant role, but argue over the relative balance of these two forces in individual development.  Then there is further debate about whether homosexuality (whether it arises mainly from nature or by nurture) can be altered, either by biological or by psychological means.

A further debate is between the essentialist and the constructivists.  Essentialists believe that homosexuality is a fixed (either by nature or by nurture) aspect of a person, in much the same way as left-handedness.   Social constructionists, however, point to the variety of ways in which homosexuality is understood (or not) in different cultures and times and say that our concept of ‘homosexual’ is simply our culture’s way of describing what’s going on now, and doesn’t actually refer to anything more than a cultural concept.  And again, there is further debate within these positions as to whether it is possible or good to change what may either be essential to the human person, or a socio-cultural construct.

 

The gender of their sexual partner, not any specific activity, is what makes a person homosexual.  I have chosen not to focus upon specific homosexual activities in this section, but rather to focus on homosexual attraction and its origin.  This is partly because the literature is most significantly weighted in this direction, but, more significantly, while there is some information regarding homosexual activity from a medical point of view, it is not essential to the debate.  There is a great deal of data linking homosexual men, especially, with high-risk sexual behaviours, promiscuity, and higher levels of psychological distress[1].  This data has been used to argue that homosexuality is, in itself, pathological.  Some writers point out that the increased levels of distress, the high-risk activities, and the impermanence of homosexual relationships (sometimes to the point of anonymity) can be explained as a response to negative social stereotyping and discrimination.  This explanation is not particularly convincing, as it suggests that the majority of homosexual men are unable to make their own decisions about how, where, and with whom they engage in sexual activity.  Nevertheless there is certainly an element of truth in it for some individuals.  The more compelling reason to by-pass this aspect is simply that it is not an issue for us.  The church has no doubt that risky sexual behaviours and promiscuity or anonymous sex is against the will of God.  We are being asked, instead, to consider the morality of a relationship that conforms to the Christian norm of marriage (exclusive, committed, caring) in every respect but the key one of gender.  And though the most common forms of same-sex sexual behaviour are seen medically as potentially harmful, the behaviour does not define the relationship.  Homosexual couples engage in a wide range of sexual activities (as do heterosexual couples); it is not the activity that makes them homosexual, it is the gender of their partner.

Two Basic Questions:  So what else does medical science and research have to tell us?  Scientists have been asked two questions about homosexuality; “What causes it?” and “Can it change?”  We may or may not agree that these are good questions, but they comprehend nearly all the scientific literature I have seen on this issue.

There is certainly not any agreement in any group about any of the scientific findings related to homosexuality.  These studies tend to focus upon early childhood experiences and family relationships, genetics, brain structures, and hormonal activity – especially before birth.

Do Parents Make their Kids Gay? Family Relationships first came to the sustained attention of science through the fledgling discipline of psychoanalysis in the 1800s.  It was they who coined the word ‘homosexuality’ to describe an enduring pattern of homoerotic attraction.  This concept wasn’t translated into English until the early 1900s.  Because psychoanalysis focuses upon the development of psychological problems in the individual by reference to their closest (usually family) relationships, they quickly developed a theory of homosexuality as a condition birthed out of an over-bearing mother and an emotionally distant father.  Homosexuality was described as a regression to an earlier developmental stage or a state of arrested psychosexual development.   Variants on this theory[2] are still popular today among those therapists who still provide a service to those who seek to change their sexual orientation[3].

Research into the reliability and validity of this understanding of homosexuality is heavily dependant upon the case notes of the therapists who have used these theories, and as therapists tend to find what they expect to see, these case histories have usually not carried a great deal of weight in scientific debate.

What Difference does it make Having Lesbian Parents?

I did find one careful scientific study  which examined the impact of family on the likelihood of homosexual development, but it was attempting to measure the impact of being raised by lesbian parents, rather than the more traditional category of ‘over-involved mother’.  The result was that:

Although no significant difference was found between the proportions of young adults from lesbian and heterosexual families who reported feelings of attraction toward someone of the same gender, those who had grown up in a lesbian family were more likely to consider the possibility of having lesbian or gay relationships, and to actually do so.  However…the majority of children who grew up in lesbian families identified as heterosexual in adulthood, and there was no statistically significant difference between young adults from lesbian and heterosexual family backgrounds with respect to sexual orientation  . 

The authors note that their study did not distinguish between nature or nurture at all, but they do provide some useful evidence for distinguishing between homosexual attraction, activity, and identity.

(Golombok and Tasker 1996, 8)

 

 

Does Sexual Abuse ‘Cause’ Homosexuality?

A more recent finding related, not so much to family, but certainly to early child-hood experience, is that reported from the University of Otago study of 13 000 ordinary kiwis.  They found that “of those who reported sexual abuse or rape in childhood, about 15 per cent were non-heterosexual. Of those who had not had these experiences only five per cent were non-heterosexual.” (Todd 2010)  Therefore, being sexually assaulted in childhood means someone is three times more likely to identify as “non-heterosexual” in later life.  Again, being abused does not ‘make’ someone homosexual, nor have all homosexual people suffered abuse!  But there is clearly a link of some sort between early childhood experience and homosexuality in some cases.

The More Older Brothers You Have the More Likely You are to be Gay!  Interestingly, one of the more reliable scientific findings is about family relationships – but of an unexpected form: there is, apparently, a significantly higher possibility of a man being homosexual the more older brothers he has[4].  The most recent findings have controlled for environmental factors (nurture) by checking for correlations with non-biological (eg adopted) brothers, and also with biological brothers raised outside the family.  The mechanism here is thought to be the development, over time, of an immune reaction in the mother to the male hormones of boy foetuses, leading to a suppression of male hormones in those boys in the womb.  There is, however, no direct evidence for this mechanism apart from some animal studies, and it remains speculative.  What has been demonstrated is that this single biological factor (number of older brothers) has a consistent impact, for whatever reason, independently of environment.  Again, though no-one knows why this is, it does seem to indicate that homosexual preference has some biologically causative factors.

Other studies[5] examine a range of biological factors that appear to be related to homosexuality.  There have been several studies that seem to show distinct differences in the structures of various areas of the brain, but none of these have been conclusive, nor have they been replicated.  While the researchers have found that there may be some evidence of biological causes for sexual preferences, they cannot demonstrate conclusively that the differences they’ve noted are not caused by the sexual preference rather than causing it, nor can they tell us how powerful these factors are, if they are causative, and nor can they describe in detail the link between the structure of the brain as they’ve observed it, and the function of the brain as it relates to sexual preference.  These studies also tend to rely heavily upon analogous studies with a variety of animals; this is valuable as it is possible to carry out experiments with animals that it would be extremely unethical to attempt with humans, but it is also limited and we should note that while homosexual behaviour has been observed in many different animals, in the wild and in captivity, and has been induced in several species through a variety of methods, there is still a big difference between the largely instinctive behaviours of rats and dogs, and the strongly socialised behaviours of human beings.

Along similar lines, unusual prenatal hormonal fluctuations sometimes associated with maternal stress, and the use of some drugs, can be shown to lead to something like homosexual preference in some mammals – and maybe in humans.

My Genes Can’t Make Me Gay:  Genetic factors have also been focused upon, and I recall the announcement in the newspapers that the ‘gay gene’ had been discovered, some years ago.  Those reports were, however, somewhat exaggerated.  Although a twin study from 1991[6] seemed to point to a definite genetic component to homosexuality, it was accused of sample bias and a later study with an unbiased sample led to a retraction of the earlier findings[7].  Other gene studies[8] have found evidence that there is a genetic element to homosexuality for at least some; but it is not determinative.  What does this mean?  Essentially, very few scientists would agree with the statement, “My genes made me do it.”  To illustrate this debate, let’s consider the Bocklandt et al study.  They found that

Human sexual preference is a …trait with a substantial genetic component.  Linkage of male sexual orientation to markers on the X chromosome has been reported in some families.  Here, we measured X chromosome inactivation ratios in 97 mothers of homosexual men and 103 age-matched control women without gay sons.  The number of women with extreme skewing of X-inactivation was significantly higher in mothers of gay men (13/97 = 13%) compared to controls (4/103 = 4%) and increased in mothers with two or more gay sons (10 / 44 = 23%).  Our findings support a role for the X chromosome in regulating sexual orientation in a subgroup of gay men.

In other words, a specific genetic variable was found more frequently in the mothers of homosexual men than in the mothers of heterosexual men.   But note that not every mother of a homosexual man had these genetic markers – it’s not necessary for this genetic variable to be present in the mother for the son to be homosexual –  also several mothers of heterosexual sons did have these genetic markers – so having these markers does not necessarily make your sons homosexual.  These researchers have simply found that there is a relationship between specific genetic factors and homosexuality, but they do not have an explanation for how these genes affect the development of homosexuality.  Clearly there is some genetic force at work, but how it works and how strong it is is up for debate.  Genes cannot make us gay[9].  They may make us more likely to be so, but there are clearly many other factors at work[10].

What all these studies demonstrate is the possibility of homosexual attraction, at least in some people, being strongly affected by biological factors as well as by events in early childhood, but none of them come close to answering the question of “what causes homosexuality?”

On Being Sensory and why I don’t ‘hug’ online.

So I was walking home for lunch, and had to slow my stride to a dawdle in order to take in the luminous magenta paintwork on a car, standing out from all the whites and greys and dark greens around it like a red rose in a blue sky.  And as I drifted closer to this intense colour experience, the Roast Station in the food-court called out to me with all the richness of it’s many-flavoured meaty menus.  I paused to drink it in.  Then on I went around the corner where a fresh, sharp wind slapped my office-heating-flushed face alive and made me blink away tears.  It was a concatenation of arresting experiences, one after the other.

I love being alive to these unsophisticated, everyday pleasures.  I love the thrill such simple things give me.  They aren’t particularly meaningful, but they are immediate, unexpected, delights.

But when I was trying to write the title to this post, I struggled for words.  ‘Sensuous’?  ‘Sensual’?  Both words mean what I want to say, but they have become entangled – mostly, I think, due to advertising – with the erotic.  And there’s nothing wrong with eros.  The sensory pleasure of an erotic moment is right up there with the whiff of Richie’s Roasts.  But there’s so much more to being sensuous than sex.  Sex must, inevitably, have some societal sanctions attached to it.  Those sanctions, in our changing society, have become a battleground for competing world-views, and so much truth about sex is forgotten as we wage our ‘culture wars’ that other concepts, like sensuousness, are dragged down with it.  Now it seems like sex is the only sort of sensuous pleasure we still talk about.  And maybe chocolate.

What a pity.

Sensory pleasures, like the ones I described above, are so rich, so free, so easy to access and share, that they should be celebrated much more often.  But we lack the language.  Not just the words, but the very concept.  We need to relearn how to immerse ourselves into the goodness of creation around us.  We need to come alive again to the value of what we hear away from the jangle and clatter of industrial life, and what we feel beyond our protective fabrics, and what we smell and see and taste.  We are bodily beings and that’s something to celebrate!

And that’s why I refuse to ‘hug’ over the internet.  Internet interactions are great for the cerebral, but pathetic for what is fully human.   This morning on social media one of my acquaintance reposted a banner that said she needed a hug, and I could ‘hug’ her by reposting the banner.  I get that she’s lonely.  I get that being single she’s not getting anywhere near the physical affirmation I enjoy myself, immersed as I am in an affectionate family.  But I also get that reposting that banner will do practically nothing about that.  The initial author of the banner might be gratified by multitudinous repostings, and my acquaintance might (did) get some positive written responses, but did she get hugged?  No.  A hug is wonderful.  When my son or daughter wraps their arms around me and squeezes and holds me, I know I’m being loved.  It’s a bodily thing.

I don’t want us to stop expressing our regard for one another in non-physical forums, but nor do I want us to delude ourselves into thinking we can be human if we cut ourselves off from our bodily experiences.  In an increasingly touch-phobic/techno-centred society (see http://www.theguardian.com/world/2013/oct/20/young-people-japan-stopped-having-sex) we need more touching, not less.  We need to be more sensory, not less.  And we need to listen to and understand what our own senses tell us about what is good, what is enough, what is too much, and what is not enough.

'Far Away' XKCD comic by Randal Munroe

This isn’t saying that we should be dominated or controlled by our senses.  We can – and sometimes must – consciously endure sensory unpleasantness for greater goals; I need to defer my sexual desires out of respect for others.  I need to pass by the sweet-smelling fruit on the grocers stall and not just help myself.  I need to suffer the physical pain of a needle prick in order to give blood.  These are not pleasant sensations – but they are easily bearable given the vast range of pleasant sensory experiences I enjoy elsewhere.  Yes, we are far more than sensory, but we are certainly no less than, and enjoying sensory experiences in no way means that we lose control of our actions.  Let’s not expect ourselves, or those around us, to live in a state of sensory deprivation.  Let’s touch one another, and shower sensory blessings upon each other; give gifts of fragrant flowers, soft cloths, rich foods, and luminous colour.

Maybe then, when we acknowledge and enjoy the full range of positive sensory experience that is available to us every day, we will be less overwhelmed by the porn/violence/gluttony industries.

Go on, be a world-changer.  Really hug someone you love today.

The Value of Encouragement

New Zealanders are feeling the cold at the moment.  Winter has well and truly begun with a cold southerly wind bringing beautiful clear skies, occasional squalls, and frost – even to our warm, sub-tropical climate.  So I spent a couple of hours in the weekend chopping firewood.  Actually, I got the good end of the stick; my wife spent a couple of hours on the sideline of a soccer field.  At least I was moving vigorously and keeping warm. 

Mind you, there can be a fair bit of vigorous movement on the sidelines, too, as parents and coaches race up and down with their players, bawling encouragement and instructions.  Son no. 2 is in a team which has a fantastic coach; the first time I watched them play, I was blown away by how positive he was towards the kids.  He was constantly telling them, individually and specifically, what they were doing right and how well they were doing it.  Not surprisingly, they continually brought home wins. 

As I was chopping firewood on Saturday morning, I didn’t get to hear the coach; but I did, in fact, get a bit of encouragement all my own.  Our three year-old son wondered out to find me.  “What you doing, Dad?”

“Chopping the fire-wood.” (swing, Grunt, *Thwack*).

“Why?”

“To make it small enough to go in the fireplace.” (swing, *ka-chunk*)

“Wow, Daddy!  You did it!”

“Yeah. (swing)”

“And you did it again!  Yay, Daddy!”

And on he went, for the next five minutes, marvelling at every log split for the fire.  And I reckon I’ve never chopped so much, so effectively, so fast.

Being a father

I’m a little ambivilent about publishing this here; it was an article in our local newspaper for father’s day 2006, and comes across as rather gushy.  I really did say these things, but I wouldn’t have edited it quite like this! 

 

For R being a father is a fantastic adventure.

A fantastic adventure, also a steep learning curve. The father of six said he’s made mistakes learning to be a father.   “I used to think I was a really nice person – and then I had children.

“The demands of caring for children require enormous sacrifice and it’s very easy to resent that. It’s easy to hit out at the little monsters that don’t behave like the perfect dolls we’d like them to be, that don’t make us feel good about ourselves, that demand we care for them when it’s not convenient for us, that cry and won’t be consoled. 

“I remember an incident when I was holding my first baby, a few months old (now 15 years old). She was screaming and I could do nothing about it. I just wanted to throw her away from me; her crying was an accusation of my inadequacy. Instead I held her and did the best I could, even though I felt that it wasn’t good enough. 

“That was the day I began to grow up as a father.”

For R the most important thing he can do, as a father, is to love his children’s mother; “and that has to be practical.”

“It takes time and effort and a willingness to learn to do things I don’t feel confident about doing or that don’t match my self-image.”

Self image in the reflection of his eldest son, C, was another  learning curve.

“No one could wind me up like C.  From the time he was six, I noticed how angry I could become about silly little things he did and said.  It took me a couple of years, but I learned that I was seeing in him so much that reminded me of myself as a child, and I didn’t like what I saw. I had to learn to love and accept myself, to stop judging and condemning my six-year old self, so that I could learn to love and accept this child who was so like me.

“Having a son has brought healing into my life and I thank God for him. Of course, his brothers get an easier time of it now that he’s taught me what’s going on,” he said.

“Each of the children are so different and each responds in a different way. I have to show my love for them in the way that best suits them. There is no one size fits all.

“Of all the different things I try to achieve, most can be done by somebody else.  But only I can be my children’s father. They get priority because no one else can do that job like I can.” 

For R the rewards of father-hood increase with time.

“Every year, my children grow and develop into more complex and wonderful people, and my relationship with them becomes more exciting and rich.” 

R said they have grown with their family and their expectations are far more realistic.

“We try not to expect them to be any more – or less – than themselves.” 

He knows that being a father doesn’t come naturally.  “There is a learning process, and with families becoming smaller, many people don’t get much of a chance to do that learning. It’s a lot more to do with closeness. Many want to get their children off their hands so they can get on with their own lives.

“I learnt a lot about being a father from being a son.  My father taught me how to be a family man – he loved our mother and he spent time with us as children.  All my best childhood memories revolve around him.  Today, I love to do with my children the things my father did with us.

“Everybody knows the saying, “It takes a village to raise a child” – for us that village has been the Baptist church.  They have loved us since the day we first came in the door with a pre-schooler and a baby, and their support continues today in thousands of ways.” R is now co-pastor.

“This town is a fantastic place  to bring up children. It has a strong community spirit.”

“If I am a good father, it’s 90% because my children have a great mother.  And I have a great wife who shares this adventure with me.”

Last year this adventure included 13 months in China. During that time R’s wife taught English as a second language while R took care of the children. The children are home schooled and for them the trip was like an extended  field trip.

“It was a huge amount of fun and learning for us. In China we were our own little community. It consolidated something we already knew; that being together as family is a fantastic adventure.”
