I'm a novice, so I'd like some perspective on this, not only from people who agree with this, but with people who disagree with this especially.
Is it possible we don't see evidence for Out-Breeding Depression in humans because modern medical intervention supersedes the consequences of Out-Breeding Depression, i.e. Asian Mothers with non Asian Fathers having a 33% higher rate of Caesarean birth, mostly due to skeletal mismatches between their Pelvic Bone and the Cranium Size of their children, an issue that in the natural world would likely result in reduced fertility within that demographic, but due to C-Sections this issue can be circumvented, and the genetic mismatch can continue to breed and spread, necessitating further dependence onto modern medicine in future generations.
Given the numerous racial distinctions:
>Fat distribution
>Muscle Anatomy
>Bone Mineralization, skeletal structure, skull shape
>Pore size
>Larynx and Speech comprehension genetics
Etc. Is it possible that more instance of out-breeding depression exist that are flying under the radar, and this is possibly one reason why the modern populations have so many health related issues?

Actually there is quite a lot of evidence for outbreeding depression, much of it gets conveniently ignored.

It's odd really. Who would have figured that miscegenation would be dangerous both to the health of human society and the individuals living in that society. It's almost like a certain tribe of inbreds wants everyone to be even sicker than themselves. They purposely promote miscegenation to get outbreeding depression.

I think that by outbreeding depression you also would outbreed intelligence.

If we look purely at fertiliy you actually start to see outbreeding effects as close as I think 5th cousin.

dumb people "deal with" depression by ignoring it. how? they just pay attention to something else instead: watch TV or listen to music all day long, talk to random people, keep themselves occupied...
I'd guess depression has some social/environmental component, most likely. so you won't outbreed anything, IMO.

"Instances of out-breeding depression" is not the correct way to call it, what you mean is "potentially lethal loss of fitness due to outbreeding depression". It's not possible, it's indisputable. You should, however, consider that in the human populations there are similarly fucktons of cases of potentially lethal loss of fitness due to INbreeding. But both of those are a minority of all genogenic syndromes. The overwhelming majority of those are either simply hereditary and not tied to a specific population, or just straight random bullshit that you cannot prevent with deliberate in- or outbreeding.Basically if you really really don't want children to be born with genetic diseases, then the only solution is to stop all reproduction. If you don't want that, you gotta balance between in- and outbreeding, and there's no real optimal point between them.

Nature wants us having big families so it can either kill most of them or prevent them reproducing in some way.
Whoever survives that pressure has genes that work well together.The more of these effective gene combinations you can maintain the fitter your offspring, relatives have more of these compatible genes so choosing a relative increases the probability that the offspring will succeed.
However mating with the less related has the potential to bring in new novel genes that could lead to better survival of the offspring.
The ultimate challenge is finding new good genes while not disrupting functional gene groups

Most of the genetic traits discussed here are complex traits, determined by dozens if not thousands of DNA patterns unique to each race.You get a chromosome from each of your parents. The chromosome you, as one parent, give to your child is a cut and pasted version of the two your parents gave you. Look up genetic combination (crossover) in Meiosis. If your parents are from different or mixed races, then you will not pass those unique racial genetic patterns to your children.Lets go by example: The HLA system. This is a protein that coats your cells and lets your body recognize & reject foreign tissue. The exact variation sequences of HLA proteins is determined by a series of DNA differences centred around chromosome 6. Chromosome 6 is a HOTSPOT for genetic crossover to occur. Crossover is THE major biological driver behind the difficulty of finding organ and bone marrow donors for people of mixed race. Meiosis will break apart established, unique racial genetic patterns, creating new, unique combinations of HLA markers. Which are impossible to find in other (donor) people.Because the HLA System is concentrated on a crossover hotspot on a single chromosome, the effects of racial mixing are IMMEDIATELY apparent in the next (and subsequent) generation(s). ie extreme difficulty in finding organ donors. Luckily, not a large % of mixed race people do require organ donors, but if they do, it really sucks.Now think about a complex trait like intelligence - where the racial DNA patterns that control the brain structures are spread over ALL of your chromosomes - you can now understand why the really adverse effects in these complex abilities are more latent, and can take a while to materialize, indeed across many generations.Someone here made the observation that some effects were only noticed after a number of generations had been born. This is the reason why. Race mixing is bad people. Not for you, for your children. And theirs.

Child investment. How close an affinity you have with your child will affect how much you're willing to invest in its future.r types fucking everything everywhere gambling on lottery numbers, while k type expends critical resources feeding and training offspring until it can fend for itself.
k types should see a greater preference for related mates as it increases the surety of return instead of someone completely different to them.

What if you thought about it socially through clannish structures?Power effectively rests in the hands of extensive cousin groups of various extraction.
Too close and you don't optimise potential numbers of allies.
too far out and they're too different.

This is one reason why humans are raciest; your mixed race offspring are less adapted to European and African conditions so will be stunted in both.
Other reasons like foreign disease and resource competition contribute to the adaptive of racism.Leftist ideology is profoundly working on many levels describing human behaviour.

Yes loads of eugenic traits are hidden by the crutching effect of modern technology. Billions will die when civilisation collapses due to dysgenic selection pressures.

Fig wasps.They all breed their siblings, have done for millions of years, being insects they can compensate with large numbers to gamble on and have had time to weed out the bad genes but they're an example of it used as a successful evolutionary strategy.

My waist is quite small, but despite this I produce the most massive shits. Poops that drastically outperform OP's in density and mass and likely in higher geometry as well. Is this also a so called "evolutionary mismatch"?I think it's the highest stage of evolution. The ability to shred through macronutrients that would turn any other modernoid obese, yet my metabolism burns through it all like sunlight beaming down on a tired niglet's brow as he mines buxite for the Belgian or the Han or whomever.OP = MOGGED.

Out-Breeding Depression as a racial hygiene problem, i.e. the take you'd get from a science racist / nazi is another one of those fucking retarded "nature can go against itself" logic fallacies that they're prone to make.If outbreeding is harmful in the aggregate it will be selected against and it wont happen. If it keeps happening on a wide scale it's because there's selective pressure in favor of it.

I know a weird fact, due to the structure of the Jersey cow's pelvis she can pretty much birth any breed's calf. Despite being only about 350-400kg.
So you could have some huge doublemuscled chianina bull lumbering around at like 1600kg and yet the tiny little jersey can birth its calf without issue.

Are any of you familiar with the Bulmer effect? I don't really understand it.
it's apparently when the more you select somehow it retains more variance than you'd think it should or how the number of trait variance change reduces each generation of selection it seems to imply that variation doesn't dissappear but I don't know how to properly understand it.

Eugenics itself- with consenting parents really isn't that immoral. In fact, it has quite a bit of potential for those who desire better traits in their offspring and would improve the human species as a whole. It's interesting, but unfortunately most people who I've brought this up in a conversation with look at me like I'm crazy because nazis used it in WW2. If people could think about it without the previous immoral use of eugenics and face it instead of immediately rejecting it, they would realize some benefits

If inbreeding and outbreeding are bad then there's a sweet spot somewhere inbetween. I'd guess that it's something like choosing a mate from the neighboring tribe or village is ideal.
