We need to stop xenoestrogen pollution

Endocrine disruptors in the environment are becoming more abundant due to a wide variety of human-related activities over the last few decades. They affect mechanisms by which the body’s endocrine system generates and responds to hormones, by attaching to receptors in similar ways to natural hormones. Minuscule quantities of hormones can have very substantial effects on the body so even very diluted pollutants may have significant effects. A sub-class called xenoestrogens specifically attach to estrogen receptors in the body and by doing so, can generate similar effects to estrogen in both women and men, affecting not just women’s breasts and wombs but also bone growth, blood clotting, immune systems and neurological systems in both men and women. Since the body can’t easily detach them from their receptors, they can sometimes exert a longer-lived effect than estrogen, remaining in the body for long periods and in women may lead to estrogen dominance. They are also alleged to contribute to prostate and testicular cancer, obesity, infertility and diabetes. Most notably, mimicking sex hormones, they also affect puberty and sex and gender-specific development.

Xenoestrogens can arise from breakdown or release of many products in the petrochemical and plastics industries. They may be emitted from furniture, carpets, paints or plastic packaging, especially if that packaging is heated, e.g. in preparing ready-meals. Others come from women taking contraceptive pills if drinking water treatment is not effective enough. Phthalates are a major group of synthetic xenoestrogens – endocrine-disrupting estrogen-mimicking chemicals, along with BPA and PCBs. Phthalates are present in cleaning products, shampoos, cosmetics, fragrances and other personal care products as well as soft, squeezable plastics often used in packaging but some studies have also found them in foodstuffs such as dairy products and imported spices. There have been efforts to outlaw some, but others persist because of lack of easy alternatives and lack of regulation, so most people are exposed to them, in doses linked to their lifestyles. Google ‘phthalates’ or ‘xenoestrogen’ and you’ll find lots of references to alleged negative effects on intelligence, fertility, autism, asthma, diabetes, cardiovascular disease, neurological development and birth defects. It’s the gender and IQ effects I’ll look at in this blog, but obviously the other effects are also important.

‘Gender-bending’ effects have been strongly suspected since 2005, with the first papers on endocrine disrupting chemicals appearing in the early 1990s. Some fish notably change gender when exposed to phthalates while human studies have found significant feminizing effects from prenatal exposure in young boys too (try googling “human phthalates gender” if you want references).  They are also thought likely to be a strong contributor to greatly reducing sperm counts across the male population. This issue is of huge importance because of its effects on people’s lives, but its proper study is often impeded by LGBT activist groups. It is one thing to champion LGBT rights, quite another to defend pollution that may be influencing people’s gender and sexuality. SJWs should not be advocating that human sexuality and in particular the lifelong dependence on medication and surgery required to fill gender-change demands should be arbitrarily imposed on people by chemical industry pollution – such a stance insults the dignity of LGBT people. Any exposure to life-changing chemicals should be deliberate and measured. That also requires that we fully understand the effects of each kind of chemical so they also should not be resisting studies of these effects.

The evidence is there. The numbers of people saying they identify as the opposite gender or are gender fluid has skyrocketed in the years since these chemicals appeared, as has the numbers of men describing themselves as gay or bisexual. That change in self-declared sexuality has been accompanied by visible changes. An AI recently demonstrated better than 90% success at visually identifying gay and bisexual men from photos alone, indicating that it is unlikely to be just a ‘social construct’. Hormone-mimicking chemicals are the most likely candidate for an environmental factor that could account for both increasing male homosexuality and feminizing gender identity.

Gender dysphoria causes real problems for some people – misery, stress, and in those who make a full physical transition, sometimes post-op regrets and sometimes suicide. Many male-to-female transsexuals are unhappy that even after surgery and hormones, they may not look 100% feminine or may require ongoing surgery to maintain a feminine appearance. Change often falls short of their hopes, physically and psychologically. If xenoestrogen pollution is causing severe unhappiness, even if that is only for some of those whose gender has been affected, then we should fix it. Forcing acceptance and equality on others only superficially addresses part of their problems, leaving a great deal of their unhappiness behind.

Not all affected men are sufficiently affected to demand gender change. Some might gladly change if it were possible to change totally and instantly to being a natural woman without the many real-life issues and compromises offered by surgery and hormones, but choose to remain as men and somehow deal with their dysphoria as the lesser of two problems. That impacts on every individual differently. I’ve always kept my own feminine leanings to being cyber-trans (assuming a female identity online or in games) with my only real-world concession being wearing feminine glasses styles. Whether I’m more feminine or less masculine than I might have been doesn’t bother me; I am happy with who I am; but I can identify with transgender forces driving others and sympathize with all the problems that brings them, whatever their choices.

Gender and sexuality are not the only things affected. Xenoestrogens are also implicated in IQ-reducing effects. IQ reduction is worrying for society if it means fewer extremely intelligent people making fewer major breakthroughs, though it is less of a personal issue. Much of the effect is thought to occur while still in the womb, though effects continue through childhood and some even into adulthood. Therefore individuals couldn’t detect an effect of being denied a potentially higher IQ and since there isn’t much of a link between IQ and happiness, you could argue that it doesn’t matter much, but on the other hand, I’d be pretty miffed if I’ve been cheated out of a few IQ points, especially when I struggle so often on the very edge of understanding something. 

Gender and IQ effects on men would have quite different socioeconomic consequences. While feminizing effects might influence spending patterns, or the numbers of men eager to join the military or numbers opposing military activity, IQ effects might mean fewer top male engineers and top male scientists.

It is not only an overall IQ reduction that would be significant. Studies have often claimed that although men and women have the same average IQ, the distribution is different and that more men lie at the extremes, though that is obviously controversial and rapidly becoming a taboo topic. But if men are being psychologically feminized by xenoestrogens, then their IQ distribution might be expected to align more closely with female IQ distributions too, the extremes brought closer to centre.  In that case, male IQ range-compression would further reduce the numbers of top male scientists and engineers on top of any reduction caused by a shift. 

The extremes are very important. As a lifelong engineer, my experience has been that a top engineer might contribute as much as many average ones. If people who might otherwise have been destined to be top scientists and engineers are being prevented from becoming so by the negative effects of pollution, that is not only a personal tragedy (albeit a phantom tragedy, never actually experienced), but also a big loss for society, which develops slower than should have been the case. Even if that society manages to import fine minds from elsewhere, their home country must lose out. This matters less as AI improves, but it still matters.

Looking for further evidence of this effect, one outcome would be that women in affected areas would be expected to account for a higher proportion of top engineers and scientists, and a higher proportion of first class degrees in Math and Physical Sciences, once immigrants are excluded. Tick. (Coming from different places and cultures, first generation immigrants are less likely to have been exposed in the womb to the same pollutants so would not be expected to suffer as much of the same effects. Second generation immigrants would include many born to mothers only recently exposed, so would also be less affected on average. 3rd generation immigrants who have fully integrated would show little difference.)

We’d also expect to see a reducing proportion of tech startups founded by men native to regions affected by xenoestrogens. Tick. In fact, 80% of Silicon Valley startups are by first or second generation immigrants. 

We’d also expect to see relatively fewer patents going to men native to regions affected by xenoestrogens. Erm, no idea.

We’d also expect technology progress to be a little slower and for innovations to arrive later than previously expected based on traditional development rates. Tick. I’m not the only one to think engineers are getting less innovative.

So, there is some evidence for this hypothesis, some hard, some colloquial. Lower inventiveness and scientific breakthrough rate is a problem for both human well-being and the economy. The problems will continue to grow until this pollution is fixed, and will persist until the (two) generations affected have retired. Some further outcomes can easily be predicted:

Unless AI proceeds well enough to make a human IQ drop irrelevant, and it might, then we should expect that having enjoyed centuries of the high inventiveness that made them the rich nations they are today, the West in particular would be set on a path to decline unless it brings in inventive people from elsewhere. To compensate for decreasing inventiveness, even in 3rd generation immigrants (1st and 2nd are largely immune), they would need to attract ongoing immigration to survive in a competitive global environment. So one consequence of this pollution is that it requires increasing immigration to maintain a prosperous economy. As AI increases its effect on making up deficiencies, this effect would drop in importance, but will still have an impact until AI exceeds the applicable intelligence levels of the top male scientists and engineers. By ‘applicable’, I’m recognizing that different aspects of intelligence might be appropriate in inventiveness and insight levels, and a simple IQ measurement might not be sufficient indicator.

Another interesting aspect of AI/gender interaction is that AI is currently being criticised from some directions for having bias, because it uses massive existing datasets for its training. These datasets contain actual data rather than ideological spin, so ‘insights’ are therefore not always politically correct. Nevertheless, they but could be genuinely affected by actual biases in data collection. While there may well be actual biases in such training datasets, it is not easy to determine what they are without having access to a correct dataset to compare with. That introduces a great deal of subjectivity, because ‘correct’ is a very politically sensitive term. There would be no agreement on what the correct rules would be for dataset collection or processing. Pressure groups will always demand favour for their favorite groups and any results that suggest that any group is better or worse than any other will always meet with objections from activists, who will demand changes in the rules until their own notion of ‘equality’ results. If AI is to be trained to be politically correct rather than to reflect the ‘real world’, that will inevitably reduce any correlation between AI’s world models and actual reality, and reduce its effective general intelligence. I’d be very much against sabotaging AI by brainwashing it to conform to current politically correct fashions, but then I don’t control AI companies. PC distortion of AI may result from any pressure group or prejudice – race, gender, sexuality, age, religion, political leaning and so on. Now that the IT industry seems to have already caved in to PC demands, the future for AI will be inevitably sub-optimal.

A combination of feminization, decreasing heterosexuality and fast-reducing sperm counts would result in reducing reproductive rate among xenoestrogen exposed communities, again with 1st and 2nd generation immigrants immune. That correlates well with observations, albeit there are other possible explanations. With increasing immigration, relatively higher reproductive rates among recent immigrants, and reducing reproduction rates among native (3rd generation or more) populations, high ethnic replacement of native populations will occur. Racial mix will become very different very quickly, with groups resident longest being displaced most. Allowing xenoestrogens to remain is therefore a sort of racial suicide, reverse ethnic cleansing. I make no value judgement here on changing racial mix, I’m just predicting it.

With less testosterone and more men resisting military activities, exposed communities will also become more militarily vulnerable and consequently less influential.

Now increasingly acknowledged, this pollution is starting to be tackled. A few of these chemicals have been banned and more are likely to follow. If successful, effects will start to disappear, and new babies will no longer be affected. But even that will  create another problem, with two generations of people with significantly different characteristics from those before and after them. These two generations will have substantially more transgender people, more feminine men, and fewer macho men than those following. Their descendants may have all the usual inter-generational conflicts but with a few others added.

LGBTQ issues are topical and ubiquitous. Certainly we must aim for a society that treats everyone with equality and dignity as far as possible, but we should also aim for one where people’s very nature isn’t dictated by pollution.
