Last fall, a group of researchers – mostly biological anthropologists and sleep researchers – published a study of three ‘pre-industrial’ communities, one in Latin America, two in Africa, and claimed that based on their data, consolidated nightly sleep is a human norm, inferring that it is the product of natural selection. The media picked up the research findings, and I read write ups of it in a number of outlets, which led me to the original article and sparked conversations with me and other sleep-interested scholars about the validity of the research. A couple of months later, I was asked by the editor of Sleep Health if I would like to respond to the findings of the article (which you can find here), in part because the researchers made an argument against a claim that I have made – corroborating Roger Ekirch – that human sleep has only recently consolidated, largely as a result of industrial capitalism in the 19th century. But I was primarily motivated by the anthropology-informed opportunity to point out that no contemporary society offers us a window to some pre-industrial past or earlier evolutionary moment. To suggest otherwise – and here I’m quoting myself – ‘verges on scientific racism.’
So what was the assumption that the researchers were working off of that would lead them to such a claim and why would I find it controversial? They took a form of social organization – namely hunter-gatherer foraging – as indicating that the people who practice that form of subsistence share qualities with a stage of human history when that social organization was predominant.
