People are discovering the truth about their biological parents with DNA—and learning that incest is far more common than many think.

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by the frequency he found in the U.K. Biobank, an anonymized research database: One in 7,000 people, according to his unpublished analysis, was born to parents who were first-degree relatives—a brother and a sister or a parent and a child.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.

    I think a third option is that porn companies think it’s what people want whether it is or not and people consume it because it’s oversaturated the market.

        I’m sure they do a lot more tracking than that. It may also be that some of these niches are more likely to have “whales”. One whale might be more profitable than many/all freeloaders

          That’s a good point i haven’t heard anyone else mention. The combination of any style of porn with a built in plotline that connects to enough whales will probably proliferate damned quick one a few people get some success with it

        That’s the easy and probably true answer. They have tons of data, they know what people actively search for and how often. They wouldn’t make it if it wasn’t profitable.

      That’s possible, though I gotta assume they use tracking. Actually, I wonder if it’s just as common outside of private mode

          I mean, I just use a private window as a matter of course because I use the auto complete for common websites and I don’t want anything untoward showing up if I’m looking something up in front of people. I gotta assume that’s pretty common, no matter what people are into.

            Yes, the bigger problem is when people think a private window does more than forget their search history and cookies on their device
