Disclaimer: I am not a parent.

I've seen a bit of discussion here on whether or not to have children. Most of the discussion that I have seen are about the moral case, but there are factors as well. I'd like to talk about three aspects of parenting that I suspect are the main reasons why people choose to have kids or not: the financial case, the moral case, and the practical case (for lack of a better term). The financial case is straightforward - how expensive is raising kids? The moral case has to do with the best use of resources: is it better to divert resources away from having kids towards charity? The practical case has to do with the actual process of being a parent - the effort it takes and the sense of responsibility. 

The Practical Case

I suspect that the main reason for why people don't have kids is because they think that kids are a lot of responsibility because:

1) It takes a lot of work and effort to raise children - effort that could be spent on other activities.

2) Great parenting is extremely important for raising well adjusted, intelligent kids that will grow up to be successful and likable adults. 

Regarding 1) yes kids do take a lot of time and effort, but that's not necessarily a bad thing - lots of things that are rewarding require a lot of effort, such as learning a language or a new skill. I don't know what its like to a parent so I won't say much more on this topic.

Regarding 2) it is actually far from a settled question whether parenting style significantly affects the kind of person that your child will grow up to be. There has been some discussion here on the effects of parenting on children. The tentative consensus seems to be that within the range of normal parenting, parenting style has only small impact life outcomes pertaining to happiness, personality, educational achievement. That doesn't mean that how you treat your child doesn't matter. Steven Pinker puts it quite nicely:

Judith Rich Harris is coming out with a book called The Nurture Assumption which argues that parents don’t influence the long-term fates of their children; peers do. The reaction she often gets is, “So are you saying it doesn’t matter how I treat my child?” She points out that this is like someone learning that you can’t change the personality of your spouse and asking, “So are you saying that it doesn’t matter how you treat my spouse?” People seem to think that the only reason to be nice to children is that it will mold their character as adults in the future — as opposed to the common-sense idea that you should be nice to people because it makes life better for them in the present. Child rearing has become a technological matter of which practices grow the best children, as opposed to a human relationship in which the happiness of the child (during childhood) is determined by how the child is treated. She has a wonderful quote: “We may not control our children’s tomorrows, but we surely control their todays, and we have the capacity to make them very, very miserable.”

The message I would take away is not to worry too much about creating an optimal child. Don't worry about finding the optimal set of extra-curricular activities or the perfect balance of authoritarianism and permissiveness. Instead, try to cultivate a healthy relationship with your child and most of all enjoy the parenting process.

The Financial Case

In agarian societies (and most societies quite frankly) children were/are cheap, in some cases free labor and a life insurance policy for when you retire. But in the post-industrial Western world that is no longer the case. For a middle-upper class family, having a child is a very large cost for two reasons: the first is that children cost a lot of money to raise. The second reason is that having a child might hold you back from advancing your career as much as you would have been able to do otherwise. I will focus on the first problem here. According to the United States department of Agriculture, the average cost of raising a child to age 18 was about $241,080 (in 2012 dollars). This doesn't count the cost of college which can exceed $250,000 at elite institutions. I'll assume the $250,000 figure for the purposes of the following calculations.

Assuming that you are able to invest your money at a modest 5% rate of return, this amounts to having to put aside $8887 each year from your child's birth for college only, and approximately $13,000 (2012 dollars) per year on other expenses such as housing and food. That $13,000 per year figure does not account for inflation and in reality that figure would grow each year but this is just to provide a rough ball-park figure. This figure goes up if you have more than one child but the per child cost goes down.

This brings up the issue of whether or not you "owe" your child an all expenses paid college education. I wouldn't rule out only paying partially for your child's college education especially since this calculation assumes only one child. I would be interested to hear more thoughts on this matter.

The Moral Case

Some effective altruists have advanced the idea that having children is immoral because the money spent on having kids would be better spent by donating it to charity. This assumes utilitarianism, and indeed if GiveWell recommended charities were perfect or even pretty good util maximizers then this argument would succeed, since by design whatever they did would be the best use of money under utilitarianism. However, I do not believe that this is the case. GiveWell recommended charities that focus almost exclusively on public health initiatives, and exclusively focus on providing aid to the poorest countries. While a simple diminishing marginal returns argument might suggest that this is the lowest hanging fruit and hence the best use of money there are other things that need to be considered.

As Apprentice points out the heritability of prosocial behaviors such as cooperativeness, empathy and altruism is 0.5, and I think most people here are aware that IQ has a heritability around that number as well and is a pretty good predictor of life outcomes. If you want to increase the number of people in the world that are like yourself, then having children is a great way of doing so. This is particularly important since high IQ college educated individuals in Western countries have fertility rates that are below replacement levels and are some of the lowest in the world.

Rachels anticipates this argument by pointing out than one child is unlikely to produce the same returns as an investment in charity. I believe this is a mistake because it is short sighted. If you stop the utilitarian analysis at one generation into the future then yes having a smart altruistic child will not give the same returns as saving lives through charity, however consequentialism need not be short sighted. If you have more than one child, and/or if your children have children then the returns get magnified significantly - and it is worth noting that intelligent people contribute a lot to society not just through charity but through their work as well. Moreover, the people you would save by donating to charity would also have children and those children would have children all of whom might require yet more aid in the future. Thus the short term gains in QALYs that giving to GiveWell recommended charities provides lead to a long term drain of resources and human capital. And as I have already mentioned, intelligent people already have the lowest fertility in society, I'd rather not see it go even lower.

Jeff Kaufman provides two counterarguments that caught my eye: that this is an argument for sperm donation rather than having children; and that genetic engineering will solve the dysgenic fertility problem. However, sperm banks are already eugenic (in a sense) and it is fairly easy to saturate the supply of high quality sperm. Sperm donation is good idea for highly intelligent individuals (and to my surprise there are actually sperm donor shortages in some parts of the world making it an even better idea), but it is not a substitute for having children - the bottleneck quickly becomes the demand for said sperm. This is certainly a potential area worth investigating as a light form of eugenics, but I don't know of anyone who's trying to market eugenic sperm donation right now. With regard to genetic engineering, I have serious doubts that the field will develop to the point of commercialization in the next hundred years, and I have even stronger doubts that it will be widely accepted and used. While I realize that prediction of the future is very difficult, I would be very surprised if in a hundred years the average Joe will think about having genetically engineered children. Any mention of eugenics already invokes fear in the hearts of most people, and its pretty hard to deny that genetically engineering babies is the scariest kind of eugenics. Human genetic engineering might well solve the dysgenic problem, but I wouldn't bet strongly on that happening any time soon, whereas having children is an almost guaranteed way of helping to solve the problem.

its pretty hard to deny that genetically engineering babies is the scariest kind of eugenics.

Pretty sure negative eugenics with concentration camps is a scarier kind of eugenics.

Don't know what I was thinking when I wrote that.

Disclaimer: parent of a bunch o' kids.

The question of "should one have children" is very different from "should YOU have children", as "should a randomly chosen LW'er on average have children" is different from "should an American", or "should a human being (including Somalians) have children". Asking the question broadest in scope, even if answered "correctly", yields mostly personally inapplicable results.

Many of the arguments you gave pertain to the generic "should one have children" more so than they do to the readership of your article, thus losing a good amount of relevancy.

Case in point: all of the different heritability coefficients are dependent on the choice of population. As you become a more reflective person with more options open for you to take, heritability coefficients change. It's like asking about the heritability of IQ going off of dog populations, then concluding that different parenting styles have only x or y impact because the dogs' "parenting" barely impacted their litter's IQ. Higher environmental variance leads to smaller heritability coefficients.

Generically determined factor... (read more)

Wow, that was excellent, thanks for writing that. I actually think that many effective altruists/ utilitarians would disagree with that and assert that there is precisely one correct moral action or use of money at any one point in time - it varies based on circumstance of course but for any one circumstance there is one correct action. Rachels would certainly disagree with that, and jeff kaufman seemed to be convinced by Rachel's argument.
2Pfft10y
If you include spouses under "friends", that might be quite common? I would say typically the spouse will contribute more working-hours in total, although children will be helpful in the last few years.
0Kawoomba10y
I most certainly don't. Relative usually refers to "someone connected by blood, marriage, or adoption".
0Pfft10y
But then what is the relevance to the question of whether to have children or not? The rest of your comment seems to implicitly assume that the only way to get more relatives is to have children.
0Kawoomba10y
My comment focused on children because that's the topic at hand; building a strong long-time bond with a significant other (or others, if you're so inclined) can be another avenue (often less reliable) of attaining a dependable support group. The comment wasn't meant to be exhaustive. Personally I'd never put a spouse in the same category as "friends" in this context, but of course you may categorize whichever way you like. (For example, I'd agree that if you count children as friends, then friends would always be preferable, since (friends including children) is strictly more support than (just children). Such trivial labelling tennis wouldn't change the underlying dynamics, of course.)
2bokov10y
Yes, exactly. I'd add: ...because the best cryopreservation arrangements won't do you much good if nobody notices you died until the neighbors complain about the smell.
2pianoforte61110y
This is true, when I wrote this I wrote mostly reacting to the many reasons that I have heard people give for not having children. With the "but its so much work!" and "but I could be spending that money on famine relief!" arguments being the most painful to my ears. So by writing about the negative case, I didn't have space (nor frankly the expertise) to write about the positive case for having children, which you have done a great job of presenting.
0NancyLebovitz10y
Even though reasonably well-off people in the US don't seem to do a lot of hands-on care of elderly relatives, they end up doing a lot of bureaucracy-wrangling-- or at least this is the impression I get from my social circle.
-13Locaha10y

I had a terminal value that I wanted to reproduce. So I have a small child, we're trying for another, and I have also donated sperm. (In the UK, if you donate viable sperm, it is pretty much certain to be used - there's a terrible shortage. So I'm going to have more kids. Free kids! Raised by someone who actively sought to have kids! They'll get my name when they turn 18, perhaps they'll get in touch ...)

Now that I have one, I can tell you that I'm enjoying this hugely. She takes up a huge amount of my time and attention. But it is utterly fascinating to watch a small intelligence develop, to watch each skill come online. She's also really cool. I like her. I'm glad her mother had two kids already, so I had someone experienced on hand ...

If you don't have a terminal value to reproduce, I'm not sure I'd actively recommend having kids anyway. But it's still pretty good IMO. Frequently exhausting, but good.

If you're smart and male, even if you don't have a terminal value to reproduce, donate sperm. Donate all they'll take.

So, how important all these deliberations will be when you girlfriend/fiance/wife looks at you and says "I really want to have a baby with you"?

And this is why you should ask your future girlfriend/fiance/wife's opinion about having children.

7Gunnar_Zarncke10y
This was actually almost the first questions we discussed before really getting together.

Should we assume it's always the female partner who wants to have a child and the male who doesn't?

4Lumifer10y
Of course not, I was talking in the context of the parent post which I assume was made by a male.
5pianoforte61110y
You correctly assumed that I am male, but incorrectly assumed that am heterosexual, not that it matters. I'd like to echo what Locaha said.
3Kawoomba10y
((Unbeknownst to the perp, the term "fiance" he so unwittingly used ("girlfriend/fiance/wife") typically referred to a male. Little did he know that not only would others miss that inclusion of the correct scenario, but that he himself would as well.))

Heh :-) I wish I were able to claim it was a cunning trap I planted in there X-)
2Lumifer10y
Mea culpa

Great comment. And some men also just want kids, without looking for logical justifications. And it can happen suddenly. Discussing things beforehand helps, but it's not a guarantee that you or your partner won't change.

-3ChristianKl10y
They provide bargaining power when it comes to agreeing which parents has to do which household work that relates to the child. You could imagine men who agree to have children provided that they don't do most of the work.
6Lumifer10y
If you need to explicitly accumulate bargaining power with respect to household chores, you (or s/he) married the wrong person. I would advise any woman who hears this proposed to her to run fast and far away.
-3ChristianKl10y
I didn't say anything about being 'explicit'. There are a bunch of woman for which that would be bad advice. It really depends on the goals of the woman. It basically a traditional model of how a marriage works. There are plenty of woman who are happy in that model. Different people get happy with different models and there no need to force everyone to replicate the same one.
1Lumifer10y
OK. If you need to implicitly accumulate bargaining power with respect to household chores, you (or s/he) married the wrong person. No, it is not. What, you really think that in a "traditional model" of marriage the man says "Oh, all right, I allow you to have a child as long as you do all the dishes forever and I never see a dirty diaper" and the woman replies "Oh, thank you, master, thank you!"..? I am not forcing anyone to replicate anything. I am expressing an opinion and giving advice. Besides what I already said, I would advise the woman to inflict some physical damage before running far away. A kick in the balls would be appropriate.
1ChristianKl10y
If you look back a hundred years ago most relationship where organised in a way that the woman did the housework and the man was the breadwinner. I think it's fair to call that model the traditional model.

Sexual division of labor is historically common (approaching ubiquitous), but a strict breadwinner/housekeeper model isn't a particularly good description of it in most of the times and places I'm familiar with. In forager societies, for example, it's common for both sexes to work as breadwinners, albeit targeting different food sources. Subsistence farmers (who make up a vast majority of the population in pretty much every preindustrial agrarian society) tend to work similarly; in a free 10th-century Scandinavian farmer's household, for example, you might see the adult men (it likely wouldn't have been a nuclear family) plowing fields and felling trees, while the adult women wove cloth, churned butter, tended animals and brewed beer.

I'm not terribly familiar with the evolution of the housewife institution, but I'd hazard a guess that it's an aspirational outgrowth of the division of labor in the upper classes of early modern societies (where "breadwinner" in the modern sense wouldn't have applied terribly well to either sex).

That's an interesting comment, thank you. Wikipedia says the divide is not ancient vs modern, but rather rural vs urban:

In urban societies, since ancient times, most men did work that earned money. They worked in workshops, banks, shops and other businesses as well as in churches, schools and the town council. It was seen as the job of a woman to be a "housewife" (homemaker).

But the reality was often different: often, if a family had a business, not only the husband but also the wife would work to make money in the business. This has been happening since ancient times.

-3ChristianKl10y
Few people mean forager values when use the term traditional values. I also not claim that the model has universal usage for everyone. I'm mainly saying that it should be considered, when it fulfills the utility functions of the involved persons.

When people in modern Western culture talk about traditional values, they usually mean the reputed values of the middle classes circa 1950 or so. The point I'm trying to make is that those values aren't necessarily reflective of the conditions most people lived under for most of history (never mind prehistory), and thus that they aren't necessarily a good guide to what people will "naturally" be happy with.

1Lumifer10y
We're not talking about the arrangement when the man works and the woman keeps house. We are talking about a man giving permission to his wife to have a baby in return for him not being bothered with house chores. A quid pro quo of sorts.
-3ChristianKl10y
No, that's the effect of what we are talking about. It one of the models you can end up when it's the woman's goal to raise children and the man's goal to pursue outside projects. When I say: "agree" I mean that both parties talk about and understand there mutual values and then come to a conclusion that optimizes those. The good that this post might do is that it helps someone to be more clear about his values. I did use a game theoretic frame to talk about the exchange, but that's just a frame. A way of talking about the issue. I certainly don't advocate that you should specifically pay attention to optimize game theoretic advantages to win against your partner.
2Lumifer10y
If the man's goal is to pursue outside projects then why would he want children anyway? And if you are describing a situation where a man does not want children, but can be persuaded to tolerate them in exchange for not being bothered with house chores, I repeat my assertion that the woman should kick him in the balls and run away.
-3ChristianKl10y
I think there a difference between being unwilling to spend a very time and straight out not wanting children.
0Lumifer10y
If the guy wants children but is unwilling to spend time, I think the woman should kick him in the balls several times. Just to be sure.
0JacekLach10y
The guy doesn't want children, but he doesn't mind having children with the woman as long as it's not too bothersome for him. The woman either really wants children, in which case this arrangement is to her benefit, or does not want children that badly, in which case they don't have children.
0Lumifer10y
You speak as if these two are the only people on the planet.
0JacekLach10y
Well, it's none of anyone elses business, so I don't see how other people being there is relevant. If you mean it in the sense of "don't settle for someone who isn't going to help you with kids, no matter how good a match you otherwise are"... Never settle is a brag

I am father of four and would like to add my view to this.

| The Practical Case

| 1) yes kids do take a lot of time and effort, but that's not necessarily a bad thing - lots of things that are rewarding require a lot of effort, such as learning a language or a new skill.

I fully agree with this. I like being a parent and playing with my children as well as educating them and observing their development. There are difficult times when there is conflict between parent and child when the child wants more than the parents want to provide esp. when the children c... (read more)

3Viliam_Bur10y
Mostly for political reasons, I guess. The rational part is that one day the parents may get into conflict and instead of playing cooperatively they will start playing against each other. At that moment the one which focused last years on their professional skills will have an advantage against the one which focused on child care. Dividing the household and child care is the most simple (and most likely suboptimal) way to reduce this advantage. In my opinion this is suboptimal in a similar way. Many people want to have their own biological children. I believe a better solution would be somewhere in a direction of caring for the children together. Somewhere between an extended family and a kindergarten; like a small private kindergarten where the parents are close friends with the caretakers. Sometimes the role of the caretaker can be changed, but it is not necessary for everyone to do it. If rationalists in some parts of the world are already moving to live closer together, this seems like a logical next step, if they decide to have children. With a critical mass of rationalists at some place we could probably invent some kind of a pyramid scheme, where the older children would take care of the younger children, so less adult supervision would be needed. This could be mixed with homeschooling, etc.
4bokov10y
That, right there, is one of my fondest dreams. To get my tiny scientists out of the conformity-factory and someplace where they can flourish (even more). Man, if this was happening in my town, in a heartbeat I'd rearrange my work schedule to spend part of the week being a homeschooler.
0Gunnar_Zarncke10y
Indeed this has been the case. I have had such an advantage during our crisis and that is one reason I could deal with it. But then caring for four children is also something you can specialize in and also has a high worth in most countries and is also some kind of advantage. Sounds like a kibbuz. I like this idea. But I still think that a professionalization of 'motherhood' wouldn't be a bad idea either. It has the advantage of high motivation. I once even read that this is generally an overdue and possibly needed step. Just cam't find the ref.

Also, deontic concerns about forcing existence on people.

"The overall effect of economic development is to greatly reduce fertility." That's very interesting, why is that?

Educated women have less children, reduced childhood mortality means less hedging to reach a desired number of children, above-noted changes away from agriculture and mandatory public schooling reduce the economic value of child labor, some other stuff.

There are widespread claims floating around the pop-sci-o-sphere that intelligence is disproportionately inherited from the mother (see, e.g. here ), which would suggest the important thing is getting smart women to donate eggs, much more than getting smart men to donate sperm. Although, I see that when this topic was briefly raised at the skeptics stackexchange, the evidence appeared to be lacking.

Apparently there's a lot less demand for eggs than sperm. I don't know why.

Scientific research on parenting has provided superior evidence-based methods that have not been widely adopted by parents due to poor technology transfer in this area. In fact., it's normal for parents chronically employ methods that have been known for decades to be counterproductive.

I think you make a valid point, but This seems to ignore conversion rates - how much utility for other people's children can you buy versus utility for your own? I wouldn't judge someone badly who saved the life of their own child over the life of a stranger's child, but I would if it was 500 children of strangers.
4mwengler10y
Judge them as badly or as well as you like. I wonder how much they will care? How often do you suppose that humans find themselves in a situation where they must choose between their own children and some larger number of other people's children. At one level, hardly ever. At another level, I'm about to buy my 16 year old daughter a car for a few thousand dollars, presumably that few thousand dollars could save the lives of a few tens of children somewhere else? Presumably every time I have taken my children to Disneyland or on a nice vacation I have used resources that could have saved many other children? Judge me if you like. I hope my children will do the same for their children as I have done for them.
0philh10y
What you describe would fit well within not-going-to-judge-you if you were spending that amount of money on yourself, so I'm hardly going to judge you for spending it on your children. This seems irrelevant? Of course if someone has different values to me, then they're not going to particularly care if they violate my values. But are you saying that you would save your own child over 500 others? Would you judge someone badly for saving their own child over 500 others? What about a million others? The point I'm trying to get across is that I feel there's a limit to how much you "should" value your own child over other children, and your original post ignored this.
2mwengler10y
Actually trying to imagine any kind of situation like this, I imagine I am putting my full effort in to saving my children. It is very hard to picture a real situation where it is a choice between one or two of my children vs 500 others. If it is some evil dictator of Alpha or Omega or a p-zombie or some other fiction we like to screw with around here offering me a choice to threaten and manipulate me, then fuck them, I'll take my children and THEY are the murderers of the other children. Frankly, it is a lot easier to imagine living with myself and Julia and Melissa after 500 nameless faceless strangers are gone than living every day without Julia and Melissa while 500 nameless faceless strangers wander around somewhere in the world doing whatever it is that nameless faceless strangers that I don't care about do. In the grand scheme of things, people are going to die, some sooner, some later. Any good or ill I do is apt to soon be lost in the noise as far as the world is concerned, whereas as far as I am concerned, it might have a rather large effect on me. So here's an interesting theory, if I work hard to please myself and everybody did that, would total utility be increased? I know I remember studying something like that theory 35 years ago. I can imagine trying to save my children and increasing my risk of failure somewhat in order to save other children with my children. I can't easily quantify this. I would delay leaving with my kids at the risk of being "too late" in order to get some other kids out of something dangerous, and a hell of a lot fewer than 500. It is hardly a matter of indifference. More a sense of agency and responsibility, my job is my kids, my relatives, my friends. I do see morality as an aesthetic decision. It is clearly not derivable. It is pretty clearly based on feelings we have which we have evolved with the help of natural selection. Which is to say our moral sentiments carry no moral weight, they are just sentiments.

I would not kidnap a strange child and kill her for her kidney in order to save the life of my child. SO in that sense my own moral sentiments respect significant limits on the lives of others over my own children. But given a chance to save my child vs save a bus going over a cliff I'd save my child. At a sort of deep level I don't even care if it makes sense. It arises from feelings bred into my brain for 10s or 100s of millions of years before a human neocortex was even a twinkle in the flying spaghetti monster's eye.

Some previous comments where I've pontificated on children: 1 2 3 4 5 6 (that last about sperm donation in the UK in particular).

One should also consider adopting vs. using sperm or eggs from banks vs. one's own genetic children. Obviously different people will have different concerns, but if I wanted to have children (which I don't), I would try to get the guaranteed-best sperm available from a bank instead of using my own.

What is this thing that you talk about?
3Gunnar_Zarncke10y
See e.g. http://www.bbc.co.uk/sn/tvradio/programmes/horizon/broadband/tx/spermbank/doron/index_textonly.shtml

Interesting. This, of course, presumes a very specific understanding of "best".
2Gunnar_Zarncke10y
A quite subjective one indeed.
2DanArmak10y
I don't really know if it exists; I never checked. Don't sperm banks provide some measures of the expected genetic quality of sperm samples (or at least of the donors)? It may not be guaranteed, but I'd imagine there would be screening for common deleterious mutations, and some general info on IQ, height, etc.
2Lumifer10y
I think sperm banks provide some non-binding guarantees about lack of known major genetic problems -- for example, you're unlikely to get genes with hemophilia. You also might or might not get some basic information about the sperm donor, e.g. race, height, or highest education degree received. I doubt each sperm donor undergoes IQ testing. All of these help (but do not guarantee) to avoid "bad" sperm. However I have no idea how to define "guaranteed-best" sperm or how will you find it in the sperm bank's vaults.
2DanArmak10y
Sperm banks are a market, so why wouldn't / aren't there banks providing more expensive sperm that they guarantee to be higher quality? It's something I really expected to exist; why doesn't it (if it doesn't)?
4Lumifer10y
Because they can't. For most reasonable definitions of "higher quality" there is no current technology which will allow you to take a look at sperm (and, say, sequence the DNA) and provide assurances about characteristics of the future person. Now, their marketing materials, of course, are a different issue :-/
0DanArmak10y
I didn't mean to imply they could measure these traits in the sperm itself; they can measure them in the donor instead. All we need is to know that these variables are heritable: IQ, height, race / skin color, emotional and personality profile, health history, family health history, specific mutations which can be tested by sequencing the donor's DNA (not the sperm).
2Lumifer10y
Partially heritable. So, let's get a bit more specific. Can you give a description (in whatever terms you like) of a donor which who will provide "high-quality" sperm of the kind that you're looking for?
8DanArmak10y
Certainly, few things are perfectly heritable. 0.5 heritability (correlation), as claimed for IQ, is quite impressive. I can list the qualities I would look for. Keeping in mind that I'm not in fact looking for sperm donors, don't have or want children, and other people would certainly want (or prioritize) other things - but that should still allow a market. * High IQ. In addition to regular IQ tests it's probably good to look at other factors like education and other intellectual achievements - would need to research to know what to look for exactly. * Physically attractive (would need to research how heritable this is) * Good personality factors - high conscientiousness, etc (ditto) * Above average height for my population, but not too tall. I remember that height is positively correlated with various good life outcomes; would need to check how tall is 'too tall'. * Racial appearance matching mine and my partner's, and presumably also matching the local socially dominant group (Ashkenazi Jewish in my case) * Good physical health, strength (lifetime) * Medical history without diseases that are known to be heritable (donor and his family) * Gene sequencing to screen for known genetic predispositions to certain diseases (donor and his family) * Donor's family known to be long-lived * Screening for factors known to adversely impact sperm (e.g. exposure to mutagens, history of cancer, advanced age at time of donation) * Donor should have already had children (whether natural or from donated sperm) that were healthy, to indicate the absence of de novo deleterious mutations in the donor's sperm cell line There are many factors I would want, but I don't know how heritable they are, and would need to research. But the above list should already lead to a much better than chance outcome that would be worth a significant price paid to the sperm bank, if I trusted the bank to ensure these qualities (to a certain degree of certainty, etc.)
6David_Gerard10y
In practice, very little of this is checked for or marketed. They check for sexually-transmitted diseases, they check for non-negligibly likely genetic problems (e.g. Tay-Sachs in Ashkenazi-descended people, sickle-cell in West African-descended people). It's possible someone is marketing sperm along the lines you posit, but I'd consider it non-negligible that they're scamming.
2ChristianKl10y
I'm not sure that artificial contraception technology is at the state where one would want to use it in cases where one can contracept naturally.
4Prismattic10y
Amusingly, this statement manages to be both strikingly correct and strikingly incorrect at the same time, depending on how one looks at it. (I think you wanted "conception" and "conceive" vice "contraception" and "contracept".)

Any mention of eugenics already invokes fear in the hearts of most people, and its pretty hard to deny that genetically engineering babies is the scariest kind of eugenics.

That's a failure of thinking that most people in the world are similar to yourself. China has a large population and not the same issues with eugenics that the West has.

A study suggests that happiness is negatively affected by having children http://www.npr.org/2013/02/19/172373125/does-having-children-make-you-happier Note, there seem to be some issues with the methodology used in the study, but it also seems to be fairly well respected in academia.

A study suggests that happiness is negatively affected by having children

It doesn't seem to. Following your link, the study suggests that working women in Texas weren't very happy when taking care of their kids.

That's an answer to a drastically different question.

2Dan_Weinand10y
Sorry, a more applicable study is behind a pay-wall. http://www.jstor.org/discover/10.2307/351391?uid=3739640&uid=2&uid=4&uid=3739256&sid=21103313626383 Summary: data from six surveys suggest negative correlation between having children and several measures of life satisfaction. Standard caveats that correlation doesn't imply causation, etc.
0Lumifer10y
Hm. Pity about the paywall. Throwing in here a PDF on the likelihood of depression among people with children and childless people. I read it as no significant difference (I understand that the authors don't feel that way).
3Gunnar_Zarncke10y
I seem to remember that this was brought up earlier and may be true to some amount. Parenting can be a lot of stress esp. if nobody honors it and/or you cannot see the value youself. Feelings of happyness are heavily moderated socially. But less happyness doesn't mean that the didn't think it to be right.
