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
New-urbanist projects The overwhelming majority of new-urbanist projects retain the almost purely residential, exclusively middle-class character of suburbia, simply substituting one formal paradigm for another. Instead of curving streets, cul-de-sacs, and half-acre lots, these developments offer grids, tightly spaced houses with front porches, and a town center instead of a shopping center containing the very same shops.
