Bro, you can't be seriously suggesting marrying your cousin. Roll tide and layoff the stepsis porn.

There is no genetic danger to the children of 3rd cousins, only benefits.

The average person has 175 3rd cousins and 1,500 4th cousins. 3rd cousins share a great-great-grandparent (4 generations) and about .8% DNA. 1/3 of 4th cousins share no DNA (theoretically).

The people you see at family reunions are typically 1st cousins. Few people have any idea who their 3rd cousins are, let alone 4th. A 23andMe DNA test misses most 4th cousin relationships.

Past 4th, the word "cousin" becomes useless and is better replaced by terms like "tribe" or "ethnicity". British people have an estimated 17,000 5th cousins and 170,000 6th cousins. This is meaningless trivia.

Unless you married someone from a different continent, you cannot know whether you or your parents are 4th-cousin married. Therefore condemning 4th-cousin marriage as consanguineous is not only incorrect but hypocritical:

Consanguineous marriage (CM) or cousin marriage is a type of interfamilial union, defined as the marriage between two blood-related individuals who are second cousins or closer

Third cousin marriage is genetically optimal. Icelanders had to track their genealogies carefully to avoid inbreeding. A study of their reproductive outcomes showed that 3rd cousins enjoyed a strong reproductive advantage. Remember, the telos of evolution is reproduction:

Women born between 1800 and 1824 who mated with a third cousin had significantly more children and grandchildren (4.04 and 9.17, respectively) than women who hooked up with someone no closer than an eighth cousin (3.34 and 7.31). Those proportions held up among women born more than a century later when couples were, on average, having fewer children.

it might reduce a woman's chance of having a miscarriage caused by immunological incompatibility between a mother and her child.

"It may well be that the enhanced reproductive success observed in the Iceland study at the level of third [and] fourth cousins, who on average would be expected to have inherited 0.8 percent to 0.2 percent of their genes from a common ancestor," Bittles says, "represents this point of balance between the competing advantages and disadvantages of inbreeding and outbreeding."

Note that this data was from Iceland, which is an extremely homogeneous population. Americans are so diverse, they might benefit from 2.5th-cousin marriage – I have no idea.

10% of marriages worldwide are between 1st-2nd cousins. First cousin marriage roughly doubles the rate of genetic disorders, from 3% for genpop to 6%. This risk is similar to that of older mothers vs young ones. However, the 6% gets higher with repeated generations of inbreeding, which is why cultures such as Pakistan with traditions of 1st cousin marriage are noticeably retarded.

The ability to breed with people totally unrelated to you didn't exist prior to the industrial revolution. In much of Europe each village has a distinctive tribal look due to near-breeding.

That is how evolution is supposed to work: nearby organisms breed with each other. Genes are synergistic and evolve cooperatively. Randomly mixing them with foreign genes destroys the local synergies that have developed. If a gene is globally dominant, then it will propagate steadily across the leaky boundaries of these village/tribal "cells" until all of Eurasia carries the gene. Meanwhile, each cell still preserves its genetic diversity, preserving the potential for future breakthroughs along its unique line of "research".

Grizzlies and polar bears are neighbors and can interbreed. However, the resulting grey bear isn't adapted to any particular environment.

Humans are intensely social, and the tribe comprises a large portion of an individual's evolutionary environment. The evolution of diverse personalities depends on a diversity of tribal environments. In a scaled atomized postmodern super-society like ours, only a few generic archetypes can thrive. Altruism and honesty are the first casualties. Shallow exploitative extroverts thrive.

Loxist Jews frequently deploy the "inbred" slur against poor "white trash", which is ironic since Jews are extremely inbred whereas Hajnal Western Europeans are extremely outbred. While there are some rare parts of the USA where first cousin marriage is common, such as among Mennonites, I don't know of any community that takes it to the point of noticeable retardation. They would be notorious if they existed, given how Yankees despise Southerners.

The USA is a young and extremely outbred country; inbreeding here is difficult to achieve, let alone sustain. That is why only cultish communities such as Amish, Mormons and Orthodox Jews are able to maintain their distinctive look.

The average American moves 11.6 times in his lifetime, whereas the average European moves 4. With local community bonds reduced to temporary shallowness, the foundation of the USA has rotted to the point of collapse. The USA is dying of atomization, and 3rd cousin marriage is the cure.

Unfortunately, the American public is not famous for its numerical literacy. One may doubt it is capable of distinguishing emotionally between 1st and 3rd. It's all just cousins, right?

However, I have faith they can do it. After all, they are ready and eager to cry pedophile over the difference between a 13 year old and a 16 year old. If you grasp that adding 3-5 more years of puberty makes pregnancy much safer, then you can also grasp that adding 2-3 more generations of genetic unrelatedness makes marriage much safer.

That's why a DNA test is one of the four tests for a tradwife. If there is a risk of some extremely rare recessive disorder, better to know right away before investing in the relationship.

OP busts this out at the family reunion guaranteed.

I married someone from a different continent, so no. Family reunions are typically focused on first cousins. If you cannot trust yourself to distinguish between 1 and 3, then of course I recommend you remain celibate. This information is for husbands considerate enough to reduce their wives' odds of miscarriage, not innumerate NPCs.

This is some real delicious stuff OP, thanks for the link. Why not 2nd cousins tho?

It just doesn't show a benefit in the Iceland study. I think the genes were too close, so some inbreeding penalty resulted, cancelling out the benefits. But Icelanders are already extremely homogeneous, so 2.5th cousins might work in the USA. Further study needed.

The extra fertility and vigor are nice but nonessential given modern medicine. However, Americans must urgently retribalize if they wish to survive their empire's 4th turning. A man's paternal clan is his natural and permanent brotherhood, as dictated by the genetic interest of his Y chromosome. You do not want to face Great Depression 2 and WW3 without a clan.
