  "account": "A viewpoint article in BioScience examines the contentious debate surrounding the origins of SARS-CoV-2, proposing a scientific approach to clarify the ongoing discussion. Author Alan B. Franklin, formerly from the USDA National Wildlife Research Center, advocates for the use of multiple working hypotheses and strong inference to break the cycle of single-hypothesis reasoning that has characterized politically charged accusations regarding the pandemic's source. Franklin, while not endorsing any specific hypothesis, emphasizes the need for a better process to distinguish among competing explanations, suggesting that this process should be guided by an objective consortium of scientists rather than media and politicians.\n\nFranklin references Thomas Chrowder Chamberlin's 1890 paper, which introduced the \"method of multiple working hypotheses\" and contrasted it with the \"method of the ruling theory.\" The latter involves bolstering a single hypothesis with selective evidence while dismissing competing explanations. Franklin argues that the search for COVID-19 origins has, in practice, relied more on the ruling theory approach than on the multiple working hypotheses approach, despite the question being well-suited for the latter. A significant challenge, according to Franklin, is that the absence of evidence does not equate to evidence of absence. He cautions that the volume of available data is not a substitute for an objective measure of the strength of evidence.\n\nThe article draws parallels from natural resource management, where structured, quantitative frameworks have been employed to resolve conflicting hypotheses and garner agreement among neutral parties before analyses commence. Franklin suggests that scientific societies could play a pivotal role in such processes, leveraging their reputation for unbiased information and ability to convene diverse groups. By involving scientific institutions in contentious issues like the origin of SARS-CoV-2, public trust in the outcome may be more robust than if only individual scientists or politicians were involved.\n\nFranklin's proposal, if adopted, could restore public confidence in scientists and the institutions that support them by demonstrating a more transparent and objective approach to evaluating competing hypotheses.",
