"Ethnic groups are real, but are socially and culturally constructed. More often than not, these groups have not had continuity across time historically, linguistically, culturally, and of course biologically. However, people intuitively tend to essentialize these groups, and DNA often serves as the placeholders for this." https://blog.oup.com/2024/03/who-do-you-think-you-are-genetics-and-identity/ #Science #STEM #Genetics #Ethnicity #DNA #Ancestry #Identity @science

"Our results show that presenting the success rate of previous raters works as an incentive to evaluate information more accurately, but that monetary bonuses provide the strongest increase in accuracy, and that only remuneration is associated with a greater use of external resources (e.g., search engines) that have been shown to meaningfully improve evaluation of new content."

"We show that most Indians derive ancestry from three ancestral groups related to ancient Iranian farmers, Eurasian Steppe pastoralists and South Asian hunter-gatherers. We uncover a common source of Iranian-related ancestry from early Neolithic cultures of Central Asia into the ancestors of Ancestral South Indians (ASI), Ancestral North Indians (ANI), Austro-asiatic-related and East Asian-related groups in India."

"We conducted a large-scale survey of 11,050 researchers and found that researchers on average rated themselves as better than other researchers at following good research practice, and rated researchers in their field as better than researchers in other fields at following good research practice. Given that it is statistically impossible for the majority of a group to be better than the group median, our results suggest that researchers on average have inflated beliefs about their own research ethicality and the research ethicality of their field."

From 2000 to 2022, the vast majority of pinning points in the 3,000-km stretch of coastline in West Antarctica from George VI Ice Shelf to Hull Glacier, along with an 800-km stretch of coastline in Wilkes Land, reduced in area or completely disappeared."

"We propose to conceptualize science-related populism as a set of ideas which suggests that there is a morally charged antagonism between an (allegedly) virtuous ordinary people and an (allegedly) unvirtuous academic elite, and that this antagonism is due to the elite illegitimately claiming and the people legitimately demanding both science-related decision-making sovereignty and truth-speaking sovereignty."
