more oxytocin fantasies: an interminable conversation 3
not sure if this measures a significant difference
Canto: So, as it turns out, the bonobo-oxytocin connection is all the rage on the internet. I mean, there are at least two articles on it. Here’s a quote from a PubMed article called ‘Divergent effects of oxytocin on eye contact in bonobos and chimpanzees’:
Previous studies have shown that bonobos and chimpanzees, humans’ two closest relatives, demonstrate considerable behavioral differences, including that bonobos look more at others’ eyes than chimpanzees. Oxytocin is known to increase attention to another’s eyes in many mammalian species (e.g. dogs, monkeys, and humans), yet this effect has not been tested in any nonhuman great ape species.
Jacinta: Hmm, so how do they know this? Presumably they’ve dosed subjects with oxytocin and measured their eye contact against controls?
Canto: No no, they know that bonobos have more eye contact than chimps, simply from observation. So they might infer from this that bonobos produce more oxytocin naturally than chimps…
Jacinta: So do women produce more oxytocin than men I wonder? I presume women make more eye contact than men.
Canto: Well in this study they dosed both bonobos and chimps with oxytocin, and the effect – more eye contact – was greater in bonobos than chimps. In fact, chimps even tended to avoid eye contact when shown images of conspecifics.
Jacinta: So, it’s a matter of interplay between this hormone/neurotransmitter and social conditioning?
Canto: Maybe, but you’d think that an increase in this supposedly touchy-feely hormone would act against social conditioning. Isn’t this the point of that drug, ecstacy? That it reduces social inhibitions… But presumably nothing is ever so simple. Being poor, I only have access to the abstract of this paper, but another abstract, which looks at the effects of oxytocin and vasopressin on chimps, describes them as neuropeptides, just to confuse matters. The abstract also refers to about a dozen brain regions, as well as specific oxytocin and vasopressin receptors, so it gets pretty complicated.
Jacinta: Okay, vasopressin… from Wikipedia:
Human vasopressin, also called antidiuretic hormone (ADH), arginine vasopressin (AVP), or argipressin, is a hormone synthesised from the AVP gene as a peptide prohormone in neurons in the hypothalamus, and is converted to AVP. It then travels down the axon terminating in the posterior pituitary, and is released from vesicles into the circulation in response to extracellular hypertonicity (hyperosmolality). AVP has two major functions… etc etc
Canto: Okay thanks for that, let’s stick with oxytocin for now. It’s produced in the hypothalamus, a smallish region buried deep within the brain, just below the larger thalamus and above the even smaller amygdala. It releases and manages a variety of hormones. Brain signals are sent to the hypothalamus, exciting it to release oxytocin and other hormones, which are secreted into the bloodstream by the posterior pituitary gland….
Jacinta: Can you tell me what oxytocin is actually made of? Its structure? The term ‘hormone’ is just a black box to me.
Canto: Okay, here’s a diagram of oxytocin to try and make sense of:
It’s a polypeptide. A peptide is basically an amino acid chain. FYI:
An amino acid is an organic molecule that is made up of a basic amino group (−NH2), an acidic carboxyl group (−COOH), and an organic R group (or side chain) that is unique to each amino acid. The term amino acid is short for α-amino [alpha-amino] carboxylic acid.
Jacinta: So these are coded for, ultimately, by genes?
Canto: Yes, we’re heading backwards here, but each amino acid is encoded by a sequence of three of the four base pairs in our DNA. Anyway oxytocin, among other things is sometimes given to women while in labour. It helps with the contractions apparently. I’ve also heard that the recreational drug ‘ecstasy’, or MDMA, works essentially by releasing oxytocin.
Jacinta: It just so happens I’ve found an interesting 2014 paper published in Neuropsychopharmacology, my new favourite journal, called ‘Effects of MDMA and Intranasal Oxytocin on Social and Emotional Processing’, and here’s a quote from the abstract:
Oxytocin produced small but significant increases in feelings of sociability and enhanced recognition of sad facial expressions. Additionally, responses to oxytocin were related to responses to MDMA with subjects on two subjective measures of sociability. Thus, MDMA increased euphoria and feelings of sociability, perhaps by reducing sensitivity to subtle signs of negative emotions in others. The present findings provide only limited support for the idea that oxytocin produces the prosocial effects of MDMA.
Canto: That is interesting. If that finding can be replicated, I’d say forget the MDMA, dose people with oxytocin. A small but significant increase in feelings of sociability might just be enough to transform our human world.
Jacinta: Hmmm. Small but significant – that sounds a mite contradictory.
Canto: Not the same as significantly small. That slightly significant dose, administered to Messrs Pudding and Pingpong and their enablers, might’ve saved the lives of many Ukrainians, Uyghurs and advocates of multiculturalism, democracy, feminism and other wild and woolly notions. And it doesn’t really transform characters, it just softens their edges.
Jacinta: Yes it’s a nice fantasy – more productive than butchering the butchers, a fantasy I occasionally indulge in. But not workable really.
Canto: Why not? We dosed petrol with lead, and look at how that worked out. It certainly had an effect. In Japan they still use radium baths (at very low levels) for health purposes, even claiming it as a cure for cancer. I’m not sure if oxytocin baths can ever be a thing, but if so I’m sure there will be early adopters.
Jacinta: Well, it’s good to think positively. Oxytocin is often thought of as a bonding hormone between mother and child. The key would be to ensure it facilitates a more general bonding: to cause Mr Pingpong, for example, to see Uyghur, Tibetan, Yi, Limi, and all the other non-Han ethnicities in China as his sisters – or lovers even, revolting as that would be to those peoples.
Canto: Better than being their oppressors and exterminators.
Jacinta: Slightly. But I wonder, quite seriously, if, assuming such a dose of bonding could be effectuated, we could still function as the sometimes rational, problem-solving, highly creative species we indubitably are. Would there be a price to pay for all that oxytocin? And how would this affect all those other hormones and neurotransmitters and all their myriad effects? Humans are notorious for causing extra problems with their solutions, e.g lead, DDT, etc etc.
Canto: Well, there’s no need to worry about the fallout from this solution as yet. I just googled Putin and oxytocin together and came up empty. Obviously we’re way ahead of the curve.
Jacinta: Haha, it’s not a curve these days, it’s a pivot. Get with the program!

leadership, thugs, hormones, bonobos, oxytocin and the future: an interminable conversation 2
just a bunch of female leaders, circa 2018
Jacinta: So, in pointing out that, according to the democracy index, female leadership and some of the best democracies go together, I didn’t mention the fairly obvious chicken-and-egg issue. Does quality governance lead to more female leadership, or does female leadership lead to better quality governance?
Canto: Isn’t this called a synergistic effect? So it’s not quite chicken-and-egg. Or is it?
Jacinta: No matter, you’re right. The term’s generally used in science – here’s an overly-complicating definition from one scientific paper:
Synergistic effects are nonlinear cumulative effects of two active ingredients with similar or related outcomes of their different activities, or active ingredients with sequential or supplemental activities.
You need to learn that – it’ll be in the test.
Canto: The idea being that female leadership and good governance result in more than the sum of the two parts.
Jacinta: Well, when I wrote about the democracy index, I found that the countries near the top of that index, the best democracies, were top-heavy with female leadership, by which I meant Prime Ministers and Presidents, but I didn’t look more closely at the social make-up of those countries – the predominance of female business leaders, scientific team leaders, the percentage of women in other political or governmental posts and so forth. I made the perhaps reasonable assumption that those countries are also leading the world in every kind of leadership position for women.
Canto: To be fair, researching all those things for each country would be quite a job. We don’t get paid for this shit. I think we can at least assume that those Nordic gals are pretty formidable. Northern European countries feature heavily in the top twenty. Even the UK gets in there.
Jacinta: Australia squeezes into the top ten. And will only improve with the new diversity in government after the recent election. And the most women in our parliamentary history.
Canto: So, as this female empowerment continues apace, at least in the WEIRD world, what will this human world look like, in the 22nd century?
Jacinta: Well, it could be – and this wouldn’t surprise me – that the macho world, run by Mr Pudding, Mr Pingpong and their enablers, and possibly their successors, will do catastrophic things before the turn for the better, because out of catastrophes – the two world wars of the twentieth century, the holocausts in Europe and Africa, Hiroshima and Nagasaki – come rude awakenings and changes for the better – the United Nations and a whole host of NGOs such as Amnesty International (1961), Médecins Sans Frontières (1971) and Human Rights Watch (1978), as well as various international defence and common interest groupings.
Canto: Yes, China and Russia – that’s to say their governments – are the scary ones, simply because they can do the most damage globally, though dog knows many African, Middle Eastern and Asian thugocracies are doing terrible things today.
Jacinta: Getting more female leadership into those countries that everybody pays most attention to – such as those with the greatest destructive ability (the USA, Russia and China) – that would be absolutely key.
Canto: The three countries most fond of interfering with other countries. Funny that.
Jacinta: What’s the point of having all that power if you can’t use it to push others around? Old Drivelmouth in the USA is a perfect example. Not to mention the Taliban, etc etc etc.
Canto: So you want female empowerment so you can push blokes around?
Jacinta: Ah, touché. Yes, there’s some truth to that – after all, we’ve had millennia of being pushed around by blokes. But I don’t want to resurrect the Society for Cutting Up Men, though I must say I’m glad that manifesto was written.
Canto: We need extremists so we can feel superior to them?
Jacinta: Haha well we can just about get rid of men, once we’ve drained them of sperm. Think of black widow spiders and such. There’s a strong argument that the basis of all life is female – turning Aristotle’s views upside-down. Anyway, we’re a long way from taking over the world, unfortunately.
Canto: And such a possible world makes me think of bonobos again, where the male life isn’t too bad at all. If you accept your place.
Jacinta: Would you be happy with that?
Canto: Well, no I wouldn’t be happy to be a bonobo after my life as a human, I’d want to do all the human things – sex of course, but also exploring where we came from, what makes us tick, how the self-animating came from inanimate matter, how the universe came to be, how we can solve all the problems we create for ourselves, and enjoying all the beautiful and amazing things, like birds and bushes, music, the sea breeze, the tastes of various cheeses, a good whisky, laughs with friends and so on. As long as my female overlords allow me these joys – and I know they would – I’d be happy as a bonobo with a perpetual hard-on.
Jacinta: Haha, I’m not sure if that’s the best definition of happiness. The spicy variety is more like it. And of course you’re right, human life is potentially much more varied and complex than bonobo life. The real point is that the potential is more likely to be realised, for more people, with less macho thuggery and more female-led community. And here’s another point: hierarchy isn’t a bad thing, or rather, it’s an unavoidable thing, because we’ll never be equal in skills and knowledge, due to age, experience and upbringing. And there will always be challenges to existing hierarchies, and changes to them. It’s a matter of how we manage those changes, and females are generally better at that. As to why, that’s a good question. Maybe it’s hormonal. In any case, that’s a generalisation, which admits of exceptions.
Canto: But those hierarchies are much harder to shift in those complex communities called nations, where there are entrenched classes, such as the Party in China, or the Military in Burma, or the Theocracy in Iran, or the Billionaire CEOs in the USA. These people tend to live as far from the great unwashed as possible, often in gated communities or their equivalents, even on physically Higher Ground, as Robert Sapolsky and others have noted.
Jacinta: Yes, that’s a good point. I was thinking recently of Nixon and his crimes, and of the USA’s ludicrous and shocking Presidential pardoning system, exposed even more in recent times. Nixon was merely ‘persuaded’ to resign, and would have spent his retirement in one of those gated communities, full of backslapping commiserators, and I have few expectations of Trump experiencing anything worse. Anyway, what we need is a society, and a political system, in which this kind of scum doesn’t rise to the top in the first place. I wonder if there have ever been any brutish alpha females in the bonobo world. It’s unlikely, but there may have been the odd one-off.
Canto: You mentioned hormones. You know, I’ve never really understood what they are. I recall Sapolsky warning us against over-simplifying – assuming that testosterone is the male hormone or the aggression hormone, and that serotonin is the relaxing hormone, mostly associated with females…
Jacinta: Serotonin’s a neurotransmitter. You might be thinking of oxytocin, which is both a neurotransmitter and a hormone, apparently. Or, more likely, oestrogen?
Canto: Yes, I’ve heard of them all, but I don’t know what basket to put them in. Is a neurotransmitter a wave or a particle? Are hormones like cells, or molecules of some kind? Amino acid chains, like so much else in the body? We should do a whole self-educating conversation on that topic.
Jacinta; Absolutely. Anyway, we need more of an oxytocin-soaked society – without the downsides of drug induction, and as long as it doesn’t interfere with our sciencey rationality too much. Here’s something from a typical popular medical website about oxytocin:
Oxytocin is a hormone and a neurotransmitter that is involved in childbirth and breast-feeding. It is also associated with empathy, trust, sexual activity, and relationship-building. It is sometimes referred to as the “love hormone,” because levels of oxytocin increase during hugging and orgasm. It may also have benefits as a treatment for a number of conditions, including depression, anxiety, and intestinal problems.
Canto: Hmmm, doesn’t it just immediately make you think of bonobos? I bet they have no problems with their intestines.
Jacinta: Well it does make me fantasise about a touch of biochemical engineering, just to help the feminising process along. Whadya reckon?
Canto: Interesting. That’s for a future conversation.
