The geneticist Jim Wilson, at the University of Edinburgh, was shocked by the frequency he found in the U.K. Biobank, an anonymized research database: One in 7,000 people, according to his unpublished analysis, was born to parents who were first-degree relatives—a brother and a sister or a parent and a child. “That’s way, way more than I think many people would ever imagine,” he told me. And this number is just a floor: It reflects only the cases that resulted in pregnancy, that did not end in miscarriage or abortion, and that led to the birth of a child who grew into an adult who volunteered for a research study.

Most of the people affected may never know about their parentage, but these days, many are stumbling into the truth after AncestryDNA and 23andMe tests.

    Now I’m not walking around thinking I’m living in a porn movie, but a rate of 0.014% is not what I would call shocking.

      Either way, what number of parent raping and impregnating their child or sibling raping and impregnating their sibling would be shocking to you? Because to most people it’s probably “anything that isn’t zero”.

        It’s shocking to you that rape exists? Clearly its a bad thing and shouldn’t happen, and it’s upsetting, but I would disagree that most people would be shocked if you told them “more than zero rapes happened this year”.

          While I agree with you in principle, I actually do think that 1/7k is unexpectedly high. If 1/10k people had an incestuous relationship, that would be low enough that I wouldn’t find it surprising. This study, if we take it to be cross-sectional, implies that the rate of incidence is much higher, at least on the order of 1/1k, possibly something around 1%. I don’t know the frequency that people of incestuous individuals have a child as a result, but the idea of it being higher than 1/7 strikes me as unlikely. Of course, multiple children can result from a pairing, so that has the potential to sway the numbers, but I’d hope that incestuous individuals are less likely to desire children from the relationship, and as a result would take a pregnancy as a sign to stop.

            Expanding on MagicShel’s comment: imagine two siblings who were put up for adoption at birth. When they grow up, they meet each other, fall in love, have babies without realising they are siblings. Who raped whom in this example?

              Expanding on my previous comment - imagine investing time and energy in creating far fetched examples to somehow make incest “ok”, but instead just outing yourself as someone who isn’t.

                There are several examples of brothers and sisters who were adopted to separate families then become couples later in life unknowingly.

                Just google it.

                You implied that all incest is a result of rape. I only have to provide one example to prove you wrong.

                You are wrong; I win

            You’re overplaying your hand here. Parent/child incest implies rape if the child is underage. Adult sibling/underage sibling implies rape. But incest of siblings who are similar age (whether adult or child) doesn’t necessarily imply rape. Even incest of a parent and their adult child doesn’t imply rape.

            Statistically I’d bet this is predominantly rape and you are largely correct, but by saying incest = rape you’ve overstepped a bit.

      Meaning that this could be an indication of a wider incest…problem?..trend?..idk…

    Given the number of blathering idiots there are, I’m kinda surprised inbreeding isn’t even more common.

    The UK actually has a big issue with incest. Especially with cousins. Causes loads of child fatalities.

    Really big issue with people from Asia, incest is the norm there.

    Edit for those downvoting me is this a recorded issue. It’s been in the news. Just because it doesnt fit the narrative or we arent meant to talk about those things doesn’t mean it isn’t happening.

        Yes. They aren’t illegal apparently. White people in the UK don’t marry their cousin from my understanding though. So it becomes racist to infringe on other cultures I guess, eventhough it is the UK and UK culture should be what’s important.

      Fun fact, Charles Darwin married his cousin. It used to be a more common among white Britons (and other Europeans, especially royalty lol), but it’s rare now. It is indeed quite common among Britons of Pakistani heritage, buts it’s becoming rarer. And the risk of genetic defects is actually quite small. I don’t think it can be considered incest when its legal.

      There is a theory that the reduction in cousin marriage in Europe reduced the power of clan groupings and led to the more indivualistic liberal culture we have now, with both good and less desirable effects (basically, more freedom but weaker communal bonds)

      I’ll upvote you if you provided a source rather than just insisting something is true because you say so.

      Edit: actually, I won’t upvote you. Incest isn’t the norm anywhere you fuckwit.

    If 1/7000 kids are the product of incest, I’m guessing that 1//500 have been lied to about their biological father; looking at you royal family of England.
