> Cameras that can capture dark skin exist
This doesn’t help when the variance in feature space of white people’s faces is objectively a lot wider than the variance of black people’s faces. You can have the best camera in the world, but it’s not going to change the fact that someone from Ireland looks way more different versus someone from Italy (in any mechanical basis) than someone from Cameroon looks versus someone from Malawi.
- ekianjo 6y agoIs this really the case though? Feature wise it's not just the color of the skin that matters, and populations across Africa can look very different from each other's even to the human eye.
- cycomanic 6y agoObjectively? You have to show some evidence, otherwise this just sounds just like "yall look alike to me". To add to this considering that genetic variations between peoples on the African continent are larger than the variations to anywhere else, this is also very unlikely. I think it's a reasonable assumption that genetic variation and variation in physical features are somewhat correlated.
- ikeyany 6y agoHN has been seeing an increase in these types of posts lately.
- cycomanic 6y agoYes, I wonder if this is because in the political climate in the US some people feel more empowered for statements like this or if the number of people holding these believes is actually increasing (at HN)

- monkeypizza 6y agoI think GP may be reacting based on common techniques of obscuring faces - i.e. ninjas wearing black masks, special ops putting dark paint on their face to obscure details. I think the effectiveness of those techniques leads people to think that darker colors are harder to see or make out. But that analogy breaks down because here we're talking about fully lit situations, right?
- centimeter 6y ago> genetic variations between peoples on the African continent are larger than the variations to anywhere else You are misinterpreting this, as does almost everyone else. Phenotypic variance is almost completely orthogonal to number of unique SNPs (which is what this generally refers to). > genetic variation and variation in physical features are somewhat correlated. This is not the case. You can have narrow population bottlenecks (reducing SNP diversity) followed by high variance in selective pressure. This is exactly what happened to early Europeans. You had a small initial population spread out to inhabit a large variety of ecosystems.
- jameshart 6y agoThis is a farcical argument. Facial recognition apps aren’t looking to distinguish gross features like Irish vs Italian features (whatever those are). They can tell two brothers from Ireland apart from one another, they should be able to tell two brothers from Malawi apart too. Their mother probably can, so why the hell shouldn’t their phone?
