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
How the Blog Broke the Web An Article by Amy Hoy stackingthebricks.com Homepages had a timeless qualityWhen Movable Type ate the blogosphereReverse chronology bias bloggingwww
Homepages had a timeless quality On the early web, there were thousands and thousands more personal homepages than weblogs. Homepages had a timeless quality, an index of interesting or useful or relevant things about a topic or about a person. You didn’t reload a homepage every day in pursuit of novelty. (That’s what Netscape’s What’s Cool was for!) Chronological content was in the minority. indexes
When Movable Type ate the blogosphere Here’s the crux of the problem: When something is easy, people will do more of it. When you produce your whole site by hand, from HEAD to /BODY, you begin in a world of infinite possibility. You can tailor your content exactly how you like it, and organize it in any way you please. Every design decision you make represents roughly equal work because, heck, you’ve gotta do it by hand either way. Whether it’s reverse chronological entries or a tidy table of contents. You might as well do what you want. But once you are given a tool that operates effortlessly — but only in a certain way — every choice that deviates from the standard represents a major cost. Movable Type didn’t just kill off blog customization. It (and its competitors) actively killed other forms of web production. constraintschoicetools
Reverse chronology bias Once you’ve had a taste of effortless updates, it’s awfully hard to back to manual everything. So they didn’t. And neither did thousands of their peers. It just simply wasn’t worth it. The inertia was too strong. The old web, the cool web, the weird web, the hand-organized web… died. And the damn reverse chronology bias — once called into creation, it hungers eternally — sought its next victim. Myspace. Facebook. Twitter. Instagram. Pinterest, of all things. Today these social publishing tools are beginning to buck reverse chronological sort; they’re introducing algorithm sort, to surface content not by time posted but by popularity, or expected interactions, based on individual and group history. There is even less control than ever before. There are no more quirky homepages. There are no more amateur research librarians. All thanks to a quirky bit of software produced to alleviate the pain of a tiny subset of a very small audience. That’s not cool at all. Navigation by shibboleth timequirks
