This article examines the rise and decline of the enthusiasm for intelligence testing in early twentieth-century China, focusing on the appeal, the challenges, and the critiques revolving around this psychological instrument. The introduction of intelligence testing reflected not only China’s urgent needs in modernizing its merit system, but also Chinese psychologists’ aspirations for pursuing exactitude and redefining the racial characteristics of their compatriots against foreign interpretations. But despite psychologists’ endeavors, the political and geographical fragmentation of Republican China troubled the epistemic (...) imperative of uniformity demanded by Euro-American psychometrics and therefore undermined the validity of measurement. Subsequently, the legitimacy of intelligence testing began to be questioned by several influential Chinese psychologists in the late 1920s and 30s. The difficulties in standardization and the hostility within the psychology community formed a vicious cycle, impeding the progress of nationwide testing. Through this history, the article demonstrates not only the elevation of measurement to epistemic authority in modern China, but also how its promise was challenged by a diverse and rapidly changing society.

This article investigates why Humboldtian Science, as a heuristic concept, has gained prominence in the historiography of science and requires clarification. It offers an ideal-type model of comparative research and exact measurements across vast spaces, which Susan F. Cannon and others tied to Alexander von Humboldt (1769–1859). Yet, he himself was less “Humboldtian” than this concept suggests. The article proposes to disentangle Humboldtian Science from Humboldt’s science, which constituted a set of individual research practices that defied the ideal of precision. (...) Humboldt’s science was often impromptu, marked by epistemological and personal insecurities, and embedded in the protagonist’s peripatetic way of living and frequently erratic writing style. Historicizing Humboldt’s science undermines the exceptionalism that elevates the Prussian savant above his contemporaries and casts him as a singular figure. This critical reflection encourages biographical approaches to the history of science, balancing heuristic generalizations and attention to individual research styles. (shrink)

This paper examines the intersection of environmental history and the history of science, specifically the impact of forestry science and fire management on land use and community dynamics in rural Portuguese mountains. It further traces the evolution of fire management from an ancestral rural practice to a scientific concern and the subsequent integration of vernacular knowledge with scientific methods. In the early twentieth century, fire was a common tool in rural Portugal for land clearance, pasture management, and soil enrichment. Rooted (...) in local knowledge, these practices were increasingly challenged by the rise of scientific forestry, which viewed fire primarily as a threat to be controlled. By the mid-twentieth century, Portuguese forestry policies had undergone a significant shift toward aggressive fire suppression and large-scale afforestation, reflecting a broader trend of prioritizing timber production and forest protection. Notable shifts occurred in the 1970s, marked, among other factors, by the increase in rural fires, a new socioecological vision for the forest and the introduction of prescribed fire techniques influenced by international models. The paper argues that the establishment of scientific fire management practices represents a merging of expert knowledge with local experience. This move represents a shift from exclusionary policies toward a more nuanced understanding of fire’s role in landscape management. An examination of these historical developments demonstrates the intricate interrelationship between science, the environment, policy, and local practices, illustrating the way knowledge systems both shape and are shaped by environmental governance.

In the 1980s, the archaeologist Merrick Posnansky implored Africa-trained scholars to investigate the Caribbean and use their training to reframe the construction of the African diasporic experience. This paper is based on research that responded to Posnansky’s challenge. Employing archaeology, community-based fieldwork, oral traditions, gender analysis, and archival sources on both sides of the Atlantic, the paper explores the history of African metallurgy, including the author’s personal research experiences in West Africa and the Caribbean. It argues for incorporating the knowledge (...) and skills of African people into a global history of iron technology. It demonstrates how the spatial and social characteristics of iron smelting and refinement have implications for the unfolding of late eighteenth-century forging in Jamaica and industrial growth in other parts of the Atlantic world. While ideas and knowledge operated in the meanings and metaphors found within both material and unseen realms, the eventual reconceptualization of this intertwined past must remain grounded in claims that can be supported by evidence. Connecting kitchens and crucibles, the study argues for an extended family of technological history. Just as understanding the global history of iron production requires attention to Africa, the inverse is simultaneously true: Africa and its history are firmly integrated in global history, including the history of the industrial revolution.

In the mid-nineteenth century, the house sparrow ( Passer domesticus) was introduced to the United States, quickly spreading across the country. For a brief period in the late nineteenth and early twentieth centuries, the observation of sparrow behavior was something of an urban pastime. Traits such as intelligence, reason, persistence, and craftsmanship were conferred onto sparrows by American urbanites. This paper argues that sparrow intelligence was often conflated with domestication: the ability of the birds to adapt to living alongside humans. (...) Praise for the ingenuity of sparrows generally revolved around their nest building, particularly when such structures overcame the challenges posed by urban infrastructure and technology. Sparrows were far less praiseworthy when they caused electricity outages or contaminated water supplies. The sparrow in the United States demonstrates how the relationship between these anecdotes and their implications for animal minds was mediated by the technology and infrastructure of cities. Admirers of sparrows were not measuring the birds’ mental capacity, but rather their ability to adapt to human habitations. Sparrows were only granted intelligence once they had demonstrated their ability to become domesticated. (shrink)
