Why Most Published Research Findings Are False A Research Paper by John P.A. Ioannidis journals.plos.org There is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance. researchsciencetruth
Be A (Re)Visitor An Article by Rob Walker robwalker.substack.com I was thinking about this not long ago while reading in Petapixel an essay by a photographer named Scott Reither, “Long Form Study: Why Photographers Should Repeatedly Revisit A Scene.” In it, he described photographing one particular stretch of beach, over and over, throughout his career. Of course that landscape has changed over time, and of course he’s had moments when he felt he’d captured the same territory so many times there was nothing left to see. But there was always something more to see — maybe because of a change in Reither’s life, rather than in the physical environment. seeingchangephotography
