1 Introduction

Reprogenetics refers to biotechnological tools used to affect the genes of a future child. How can society develop and use reprogenetic technologies in a way that ends up going well?

This essay investigates the history and nature of historical eugenic ideologies. I’ll extract some lessons about how society can think about reprogenetics differently from the eugenicists, so that we don’t trend towards the sort of abuses that were historically justified by eugenics.

(This essay is written largely as I thought and investigated, except that I wrote the synopsis last. So the ideas are presented approximately in order of development, rather than logically. If you’d like a short thing to read, read the synopsis.)

2 Synopsis

Some technologies are being developed that will make it possible to affect what genes a future child receives. These technologies include polygenic embryo selection, embryo editing, and other more advanced technologies1. Regarding these technologies, we ask:

Can we decide to not abuse these tools?

And:

How can we decide to not abuse these tools?

In other words, there is an open problem: What ideology should we have around the development and use of reprogenetics?

An ideology called “eugenics” arose in the late 19th century, ascended to power in much of the developed world in the first half of the 20th century, and then slid into ignominy after the Second World War and the genocidal horrors of Nazi Germany. Eugenic ideology motivated cruel state policies such as pressured or forced sterilization, euthanasia, and racial discrimination, as well as invasive social pressures on people’s private reproductive choices.

Eugenics was the closest thing that has existed to a pervasive ideology based around somehow intervening on human reproduction. Since eugenics went almost maximally poorly for society, it raises the question of how to avoid outcomes like that. The strategy I take here is, coarsely speaking:

A bit more precisely, the goal is to construct an ideology that can structure how society relates to reprogenetics, so that the benefits of reprogenetics are realized without risking the abuses of historical eugenics. To do so, I try to construct bulwarks, within an alternative ideology, against each of the wrong ideological engines that would take society in the direction of enacting eugenic abuses. (This is probably not actually something that can be accomplished with perfect confidence and coverage; how much it can be accomplished, quantitatively, remains to be seen.)

It’s tempting to make a shallow analysis of historical eugenics and what was wrong with it, and be done with the issue. For example, we could simply say that historical eugenics was coercive, and coercion is what made it bad. To negate this, we will instead subscribe to non-coercive eugenics. Problem solved? As another example, historical eugenics was often negative, i.e. it involved suppressing some people’s reproduction; we could instead subscribe to only positive eugenics, which only promotes reproduction (perhaps selectively) and which therefore involves less hostility.

However, neither of these could be called a moral or ideological core of eugenics. For the most part, eugenicists did not specifically set out to be coercive or to suppress reproduction (though some of them probably did, in some sense, set out with that goal). Rather, they set out with various other goals, such as purifying the gene pool of disease, reducing the burden on society of caring for the ill, or bringing about a racial utopia. The strength of their various justifications proved in the end to be enough to enact abusive policies. Furthermore, there were eugenic policies that were non-coercive, positive, or both, while still being abusive and still being an integral part of an ideology producing other abusive policies. (See the section “Some basic moral elements of eugenic ideologies”.)

In fact, I’ve found eugenics to be difficult to characterize in a simple and comprehensive way. Eugenic ideologies were quite pervasive, showing up in the Anglosphere, in Europe, in South America, and in some places in Asia. As a correlate of their pervasiveness, eugenic ideologies were highly variegated. They came in many forms: different goals, different implementations, different associated politics (from reactionary to progressive), and based on different scientific understandings (from Weismann vs. Lamarck, to Pearson vs. Mendel). (See the sections “The variegation of eugenic ideology” and “The goals of eugenics”.)

That said, I think there is something like an ideological core of eugenics. Roughly speaking, the core idea can be stated like this:

There are Good traits and Bad traits that a child could be born with. These traits impact everyone, so they’re very important. Therefore, we should make sure that future children are born with Good traits and not with Bad traits.

(See the section “The Eugenical Maxim as the shared moral core of eugenics?”.)

From this core idea of Good and Bad traits, other elements of historical eugenics logically flow. If you believe in a single notion of Good traits, you might tend to justify (over)confidently applying that criterion to everyone. You might believe, as a correlate, that there are Good and Bad people, or families, or even races (the ones who tend to have more Good or Bad traits, respectively). You’d probably view non-standard individual genomic choices as deviant, affording state-enforced prohibition; you might even view the Goodness of traits to be a state interest that’s so compelling it can even justify blunt coercion such as forced sterilization of undesirables. (See “The mindsets that underlie eugenic ideologies” and “How eugenic mindsets flow from the Eugenical Maxim” below.)

We can approximately negate this idea of Good and Bad traits. Then we can take that negation, and incorporate it into an alternative ideology around reprogenetics. For example, we can incorporate it into my proposed alternative (which I call “Genomic Emancipation2), as follows:

There aren’t Good and Bad traits that can be decided on by collective consensus. Instead of imposing a consensus idea of Good traits on future children, parents should be empowered to autonomously make genomic choices on behalf of their own future children.

Since genomic emancipation negates the core idea of eugenics, it is opposed to eugenics. (See the section “Comparison of eugenics vs. genomic emancipation” below.) For example:

However, just negating the core idea isn’t enough of a bulwark against eugenic ideologies. As an ongoing project, we want to have detailed policies, ethical rules, and ideals that provide guidance for people interacting with reprogenetics. These policies, rules, and ideals should steer society away from mindsets that contribute to eugenic abuses, and should provide legible norms that society can coordinate to enforce. Some ideas are listed below in “Some practical norms for good development of reprogenetics”. For example:

4 What is eugenics?

The history of eugenics is well-documented, and it is large and I’m not well-informed about it, so I won’t go into much detail here. To fix in our minds a picture of how eugenics has historically been applied that’s hopefully clear enough for our purposes, the next two sections will describe some concrete aspects of the wide range of eugenic ideologies. Several of the subsequent sections will summarize some aspects of historical eugenics, especially focusing on its underlying ideological engines.

For a concise and informative history of eugenics, see Diane Paul’s 1995 book “Controlling Human Heredity: 1865 to the Present”4. For a good overview of the debate around “liberal eugenics”, see the Stanford Encyclopedia of Philosophy article “Eugenics” (written by Sara Goering (2014) and revised by Inmaculada de Melo-Martin (2022))5.

5 The variegation of eugenic ideology

Eugenic ideology was pervasive in the first half of the 20th century. It had strong support in the societies of much of the Anglophone and European world, and has been seen in some form in countries ranging from China and Russia to Canada, Brazil, and India7. It enjoyed wide uptake among most sectors of society: among the subscribers to some form of eugenic ideology could be found many scientists, other academics, professionals, elites, workers, peasants, Protestant clergy, and judges. Hundreds of universities offered courses on eugenics, and social organizers ran programs aimed at promoting or suppressing reproduction within and between various groups of people. Many actual and proposed state policies carried eugenic justifications, including racist immigration restrictions as well as hundreds of thousands of forced or pressured sterilizations. These aggressive eugenic policies culminated in the horrors of Nazi Germany, but did not at all start or end there.

While there were practical objections to specific eugenic policies, e.g. disputes about the scientific basis for their effectiveness, there was little pushback against the morality of eugenic ideology. A few exceptions: The Catholic Church objected to sterilization due to the sanctity of procreation, Britain’s Labour Party objected to eugenics because it would target the working class, and liberal individualists objected to eugenic infringements on autonomy8.

A correlate of the pervasiveness of eugenic ideology was the extreme variegation of the ideologies held by eugenicists. As described in the following subsections, eugenicists had a wide range of political views, scientific understandings, implementation policies, and eugenic goals.

5.1 Politics

There were eugenicists who were reactionary, conservative, progressive, socialist, technocratic, aristocratic, populist, or utopian. Opinions on eugenic policy changed not just with scientific understanding, but also with political and economic shifts.

5.2 Scientific understandings

5.3 Implementation policies

5.4 Justifications, motives, and goals

See the next subsection.

6 The goals of eugenics

In trying to understand what eugenics is, and how to avoid bad outcomes related to genetics and reproduction, we want to understand what the underlying driving forces behind eugenics are. Eugenics, as it actually played out, is presumably the result of some mixture of different social attitudes, socioeconomic and political conditions, scientific knowledge and tools, and other conditions; and this mixture varies in different places and times; so a full causal fault analysis would be difficult and complicated.

But as one step, we can at least aim to understand the goals behind eugenics, and maybe hope to thus find a fulcrum of eugenic ideologies and policies. However, at least at first blush, the goals for eugenics (both implicit and explicit) are quite variegated as well. They include:

7 Some basic moral elements of eugenic ideologies

One wonders: What even is eugenics, if eugenic ideologies can have this variety of political associations, scientific bases, implementations, and motives? Is eugenics one thing, or just a family resemblance of different ideologies having something to do with genetics and reproduction, held by a variety of people from different countries, ethnicities, and sectors of society? Is there a core element of how eugenics is justified that is morally objectionable, so that other practices that avoid that core are morally acceptable?

Historical eugenics was very often coercive, implementing policies using force. Does this define eugenics, so that a policy that is non-coercive is not objectionable as eugenics? Or is eugenics defined as negative, so that a policy could be acceptable as long as it does not involve suppressing specific people’s reproduction, but only encouraging? Imagine the government started paying specifically light-skinned people to have children. This would be non-coercive (as usually understood, leaving aside that it involves taxation), and it would be strictly positive (incentivizing specific people to reproduce more). But it would also be wrong and eugenicsy.

Is it eugenics exactly when the government does anything involved with influencing reproduction? But if there were a huge social movement to socially pressure poor people or dark-skinned people into not having kids, that would also be wrong and eugenicsy. Is eugenics about Social Darwinism, racism, or race wars? These orientations played a central role in many eugenic abuses, but supremacism in some form is not the least bit unusual, and people made plenty of progressive and race-neutral arguments for eugenic policies.

Of course, these elements, such as coercion and racism, are important to understanding eugenics. They are central drivers of the worst historical abuses. And, although they don’t offer an exact comprehensive definition of eugenics, they do show some of the main moral structure of eugenics. For example:

But, although these elements help parse eugenic ideologies, they don’t give a single, clear, underlying core ideology that generates the whole eugenic perspective and policy set.

8 The Eugenical Maxim as the shared moral core of eugenics?

In trying to find a moral core of eugenics, one tack we could take is to focus on the state. Most of the worst actual actions taken under the banner of eugenics were taken by a state. However, going one level deeper to find the motivations for state eugenics, we find a variety of motivations, which mainly only look the same in that they are pursued through state eugenics.

Abstracting away from a concrete state, we can look more generally at the collectivity of society. Historical eugenics is motivated by some kind of collectivity—in a few different flavors, such as:

The general idea of collectivity is important, and I think it’s correct to draw from the above description a conclusion, inter alia, that goals specifically about reproduction should not be pooled into collective goals unless absolutely necessary. But ultimately “something to do with collectivity and intention” is a bit of a conceptual grab-bag. It’s vague, and in particular it doesn’t explain what, if anything, would be wrong with eugenics; in general, we rightly invest in collectivity all the time.

An idea I’ve entertained is that, in the end, it all comes back to the name: “eu-genics”, good-birth / well-born. According to this proposal, eugenics essentially means something like the belief that there is a single universal notion of Good traits that should be passed on to future children. In other words, a eugenicist is someone who subscribes to the following “Eugenical Maxim”:

For each future child, there are traits that are Good for that child to be born with, and traits that are Bad for that child to be born with. Since there are so many future children, the Goodness and Badness of the traits of future children is multiplied many-fold, and therefore in aggregate those traits are extremely important. THEREFORE, we should as much as possible use available tools to give future children Good traits and not Bad traits.

The variables in the Eugenical Maxim have differed between different eugenicists: which particular traits are considered Good or Bad, for whom exactly the traits are supposed to be Good or Bad, who is “we”, what tools are available, and what “as much as possible” means (e.g. what other ethics to override). But I think that:

  1. All eugenicists would subscribe to the Eugenical Maxim (with some setting of those variables).
  2. All centrally eugenic activity flows from (is motivated, justified, and designed by) the Eugenical Maxim.
  3. A central poison of historical eugenic ideologies is subtly contained in the notion of “Good” and “Bad” traits, as they are applied in the “Therefore”. If it is “we” who are giving children “Good” and not “Bad” traits, then it is “we” (whoever we are) who are deciding what traits to give to future children. Whoever subscribes to the Eugenical Maxim is implicitly saying “When it comes to judgements of which traits are Good and Bad, the judgements that will be made by me or my group (my social class, my scientific community, my state, my government department, my political faction, my ideological strain) will be the right judgements, and they should be implemented (for everyone).”. This is an incorrect proposition and leads to the evils of historical eugenics.

This may be a bit confusing because, while I claim to not be a eugenicist, of course I do have plenty of opinions about what traits are good and bad. Let the children be at least reasonably capable in most or all normal physical and mental ways, and as free from disease and aging as possible, and of high intelligence and moral goodness and wisdom and kindness and diligence and creativity. In fact my position is indeed a bit strange. I would say “Yes, there are good and bad traits; and I would even say that these traits are even objectively good or objectively bad (with plenty of caveats); but the fact that there are objectively good and objectively bad traits is not what justifies the use of reprogenetics. Instead, what justifies the use of reprogenetics is emancipation—empowering future children in absentia, and empowering parents on behalf of their future children, to make genomic choices autonomously for themselves.”. (See “Genomic Emancipation13.)

To put it another way: Often, when the question of reprogenetic technology comes up, people will ask: “But who decides what ‘good’ means?”. A eugenicist says “Someone”, and a genomic emancipationist says “No one”—which is to say, “No one person or body would decide; instead each person decides for themselves, or as in the case of future children who cannot decide for themselves, the next best steward—the parents—decide on behalf of their future children as best they can.”.

Why can’t we make this definition of eugenics simpler, and just say that eugenics means any belief of the form “Someone’s notion of good and bad traits should be imposed on someone.”? This is conceptually simpler. And indeed, some people do use this as a definition of eugenics, and on that basis they critique even liberal, pluralistic, autonomous, personal, emancipatory uses of reprogenetics, saying: “Even if it’s just two parents imposing their notion of good and bad traits on their own future child, that’s too much imposition, too much control, and it’s immoral.”.

The reason that the narrower definition is interesting to me is that it seems to more cleanly divide bad policy about reproduction in genetics (as demonstrated in historical eugenics) from good policy (as hopefully demonstrated in genomic emancipation and good reprogenetics). It could therefore offer a more clear guide to getting good societal outcomes from reprogenetics and avoiding the repetition of historical eugenic abuses.

In other words, the Eugenical Maxim is based on the idea that there’s such a thing as Good and Bad genes or traits, where Good and Bad means “what we should implement”. From the inside, it feels like just believing that there’s such a thing as Good traits, because of course if there are Good traits then children should be given Good traits. Historical eugenicists set out to figure out which traits Are Good, and set out to make future children (as many as possible) have Good traits. They seemed to expect to find wide enough consensus about which traits Are Good and that those traits should be given to future children. In doing so, the eugenicists acted on the Eugenical Maxim.

To instead think in terms of genomic emancipation, I still want to know what traits are Good and Bad (with various caveats). But I don’t identify that with “what traits people should have”. As a moral question, reprogenetic choices should be imposed upon a person as little as possible; and only imposed by those who are as close as possible to that person and who are as intrinsically concerned as possible with that person’s flourishing; but no less than necessary to accrue the clear benefits to that person by humane genomic choices made in accordance with their will or their best steward’s will. The state can’t be trusted with any say in reprogenetic choices beyond the most extreme cases (see exceptions listed in “The principle of genomic liberty14); clinics should follow their own ethics around the edge, but should mainly aim to neutrally and honestly inform and empower parents; and parents should try to do what’s best for their future child according to what that future child would want.

9 Euphemics

To explain with an analogy, we can imagine an ideology called “euphemics”. A Euphemicist believes that there are Good things to say and Bad things to say. Since there are Good things to say and Bad things to say, and so many people say so many things, it’s very important that people say Good things. For that reason, we should as much as possible use available tools to make people say Good things and not Bad things.

It’s strange—it sounds so reasonable and logical, but then you’ve just derived the urgent need for a Ministry of Truth, funded and legislated and enforced by the state. How would you argue against this?

It’s not that there aren’t Good and Bad things to say. It’s just that it’s not that kind of Good and Bad. It’s not the kind of Good and Bad that justifies centralized imposition on everyone. You haven’t investigated enough to justify thinking that you’ve reached objectively correct answers; even if you investigated more, there isn’t an entirely objective answer (e.g. because it’s value-laden and context-dependent); and even when you knowably have the objectively correct answer, that doesn’t mean you should coercively impose it on others because that could be defecting in an epistemic Prisoner’s Dilemma.

We can give more specific, concrete reasons that Euphemics is harmful in practice. Diversity of opinion and the marketplace of ideas would produce better ideas in the long run; suppressing speech often doesn’t get rid of harmful thinking and leaves it unaddressed and festering; no centralized authority will be competent enough to cybernetically control the sphere of speech in a net-beneficial way; a central authority is way too much power to wield and would be corrupted and biased; apparently contradictory propositions are sometimes actually just spoken in different languages; some propositions are ambiguous or actually context-dependent (e.g. “It’s raining.”); etc. But we can also compress this into a simpler message: “There’s no such thing as Rightthink and Wrongthink.”.

An argument is sometimes made like “Eugenics just means good birth; how can you be against good birth?”. To go further with the theme of etymology, we can look at “good” (en.wiktionary.org/wiki/good). “Good” comes from Proto-Indo-European *gʰedʰ-, meaning “to unite, to join”; from that root come also the words “gather” and “together”. So “good” is conceptually related to uniting. “Goodness”, in this etymological sense, is related to the collectivity—it’s about consensus, and about the Good of the many. We could say that, etymologically, good-birth is about collective decisions about birth. Genomic emancipation negates collective decision-making about birth, and negates the “good” in “eugenics”.

10 Avoiding the ideological engines of eugenics

I’m partially satisfied by the above analysis of eugenics as stemming from a belief in objectively Good and Bad traits. I think the analysis at least strongly pushes against a total Wittgensteinian retreat to understanding eugenics as a mere family resemblance. The analysis instead gives a reasonable conjecture about a single central throughline to eugenical ideologies, suggesting that eugenics is a Thing.

However, we have to admit that, whether or not the Eugenical Maxim can be truly said to be the moral core of eugenics, the Maxim doesn’t explain enough about the nature of eugenics. It doesn’t clearly give society enough understanding to succeed in the ongoing task of steering clear of eugenic abuses. One of the key questions in analyzing historical motives is to understand what constitutes an engine of ideology which would tend to drive us towards bad places. That understanding would empower us to not drive in that direction.

We especially need the ability to avoid driving towards bad places if we’re going to develop reprogenetic technologies: If we’re doing reprogenetics, then several tools, individual interests, political momenta, and background beliefs, any of which could incite and support eugenic motives, would become much more available. For example:

So, to avoid leading to eugenic abuses, we’d have to avoid whatever ideological engines would, within that new context created by reprogenetics, drive us towards bad outcomes. To avoid those engines, we’d want to clearly have an alternative ideological engine that is opposed to eugenic ideologies, and that can beneficially structure how we implement reprogenetics. That’s a main reason to understand what those ideological engines are. (Another main reason is to track them as they grow, and to cut off their connection with the context created by reprogenetics. For example, we’d want to make the case that the logic of “if heredity matters, then we should do racist/eugenic policies” is a bad logic, separately from the question of whether or not heredity is real and matters.)

11 The mindsets that underlie eugenic ideologies

Can we go deeper? Can we see the ideological engines of eugenics more clearly?

We can list some mindsets that, in some forms, when held by single people or by groups of people, could lead to eugenic abuses. (Note that this list emphasizes the downsides of these mindsets because we’re analyzing how they contribute to eugenic abuses, but some of them in some forms have important upsides. E.g. collectivism can motivate beneficial social welfare policies, high modernism produced efficient housing and utilities, and a healthy skepticism of doomsaying about sacredness makes way for technological innovation.)

Here are some of these mindsets:

12 How eugenic mindsets flow from the Eugenical Maxim

To illuminate the structure of eugenic ideologies a bit more, this section lists some ways that the eugenic mindsets listed in the previous section are given support by the Eugenical Maxim from the above section “The Eugenical Maxim as the shared moral core of eugenics?”.

I would presume that these connections cannot even come close to fully explaining how and why any given instance of eugenics happened (any specific advocacy, state policy, or social attitude). Take, for example, the behavior of Nazi Germany. That behavior was of course heavily influenced by eugenic ideologies in multiple ways—think for example about ideas of racial purity and racial conflict; ideas of the population as a single body with contamination, purity, cleansing, and weak elements; subordination of the individual to the nation and the state; and utopian visions of the gene pool. However, there was ample ideological kindling from other sources, such as mystical ideas of the Volk, as well as anti-Semitism as a method of scapegoating (perhaps for fears of modernity)21. That kindling was added to by Germany’s military defeat and humiliation, and by severe economic strain, before being ignited.

So, the support from the Eugenical Maxim given to eugenic mindsets is only partial. Furthermore, the direction of support is ambiguous (perhaps depending on particular cases, or depending on what question we’re really trying to answer). Which comes first, authoritarianism or eugenics? Which comes first, high modernism or disrespecting the sacredness of procreation? We can note that the causality can go in both directions (surely high modernism promotes believing that there are objectively Good and Bad traits which can be measured well enough for any practical purpose, and that belief promotes high modernist policies), and also allow these relationships to be open questions.

Still, I think these (vague, conjectured) connections show some important elements of how eugenic ideologies work. In the following, “promotes” means “would tend to often, though not necessarily, promote”. A belief in objective Good and Bad traits promotes:

13 Aside: When people have different discourse goals

Discussions about big social and state policy questions often get tense. One source of tension is discourse goals that differ between two interlocutors. For example, one person might try to think through a domain by sharing factual information; but another person might be focused on promoting and demoting various policy proposals, and might interpret the first person’s factual statements as supporting or attacking some policy proposal, and then object to that support or attack. Neither person is necessarily in the wrong; it could be that both people are doing good and useful computations, even if the result is misunderstanding and apparent conflict. (Of course, there can also be actual conflict.)

This kind of talking past each other comes up a lot in the case of reprogenetics. Questions like “Is this eugenics?” tend to come up, and then interlocutors somehow fail to engage with each other. Here are some categories of discourse goals around reprogenetics, and in particular around questions like “Is this eugenics?”:

In my view, all of these ways of engaging in discourse are reasonable and have their place. I think it’s worth keeping in mind that there are different legitimate discourse goals. Without keeping discourse goals in mind, people might repeatedly exchange statements with each other that seem, to the other person, to be statements made in bad faith (e.g. off-topic, evasive, or willfully misunderstanding). Hopefully, with goals in mind, people’s statements would seem at least not adversarial when they really aren’t adversarial; and ideally, people could decide together to work together towards whatever shared goals they might have. I would also suggest that someone who puts a lot of weight on one mode of discourse might benefit from being open to other modes (ideally in a mutual exchange).

14 Comparison of eugenics vs. genomic emancipation

This section compares the ideology of eugenics against the ideology of genomic emancipation. One goal of explaining the differences between those ideologies is as part of a defense of genomic emancipation. Another goal is to more fully construct an ideology of genomic emancipation that would lead to desirable futures. (See “Appendix: Why envision genomic emancipation?22.)

14.1 Overlaps

Here are claims that a eugenicist and a genomic emancipationist would agree on:

14.2 Disoverlaps that border the overlaps

Those overlaps are only partial. Here are some delimitations of these overlaps, showing some of where eugenics and genomic emancipation come apart:

14.3 Disoverlaps of core ideology

The Eugenical Maxim described above in “The Eugenical Maxim as the shared moral core of eugenics?” summarizes eugenics as believing in Good and Bad traits that strongly affect society and that therefore should be strongly promoted in the population.

Genomic emancipation (as described in “Genomic Emancipation24) approximately negates the Eugenical Maxim. The simple concrete meaning of genomic emancipation is:

Making biotechnology to empower parents on behalf of their future children.

The abstract ideal of genomic emancipation is:

The birthright of human spirits includes fuller self-unfolding via self-sovereignty over their own genomes.

Eugenics says that there are Good and Bad traits, selected for by society and/or nature. Genomic emancipation says that there are not Good and Bad traits in that sense; individual choice is somewhat opposed to the judgements of both society and nature, and individual choice should generally win out. Parents should make autonomous genomic choices, and these choices should reflect some differences between parents in ideas of what traits their future children should get. There are ethics of genomic choice under genomic emancipation, but they don’t derive from a universal imposed notion of Good and Bad traits.

A eugenicist would justify developing reprogenetics because it’s Good / Bad for these genes / traits / people / races to be propagated. A genomic emancipationist would justify developing reprogenetics because it’s good for people to be empowered autonomously.

14.4 Disoverlaps of concrete aims

Eugenics and genomic emancipation overlap in some concrete goals—mainly, wanting to develop reprogenetic technologies (including the scientific understanding of reproduction and of the genetics of traits). But, they diverge on most key goals:

14.5 Disoverlaps of mindset

Eugenics and genomic emancipation differ on several underlying mindsets:

15 Some practical norms for good development of reprogenetics

A main goal of this investigation has been to help construct an ideology for the beneficial development of reprogenetic technologies. As a subset of that goal, we want to construct a social policy platform that would avert any tendencies of society to use reprogenetics in abusive ways in the vein of historical eugenics.

That’s a big project that isn’t completed. But from the investigation in this essay, we can take away some ideas. Simply writing down these ideas doesn’t solve anything. My hope is that stating an ideology for beneficial reprogenetics will help that ideology be socially and politically implemented: as society builds a consensus ideology, that ideology can turn into concrete norms and shared goals that protect and uphold what we care about in the domain of reprogenetics. Thus, even relatively obvious ideas are worth stating because, beyond just explaining the idea, the statement plays the additional role of putting the idea into common knowledge, or at least proposing to do so.

The following list is focused on the anti-eugenics aspect of genomic emancipation; see also “Genomic Emancipation26 for other aspects. Some takeaways:
