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
revisiting architectural blogging An Article by Alan Jacobs blog.ayjay.org I have appropriated from Brian Eno and others the distinction between architecture and gardening, and have described my blog as a kind of garden. But lately I’ve been revisiting the architecture/gardening distinction and I have come to think that there is something architectural about writing a blog, or can be – but not in the sense of a typical architectural project, which is designed in advanced and built to specifications. Rather, writing a blog over a period of years is something like building the Watts Towers. Simon Rodi didn’t have a plan, didn’t even have a purpose: he just started building. His work was sustained and extended by bricolage, the acquisition and deployment of found objects – and not just any objects, but objects that the world had discarded as useless, as filth. You put something in here, then something else, you discover, fits there … over time you get something big and with a discernible shape. Not the regular shape envisioned in architectural drawings, but nevertheless something that can be pleasing or at least interesting to look at – an organic and irregular shape. A geometry of irregular forms. architectureblogginggardens
