Why Most Published Research Findings Are False

Why Most Published Research Findings Are False: 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. Simulations show that for most study designs and settings, it is more likely for a research claim to be false than true. Moreover, for many current scientific fields, claimed research findings may often be simply accurate measures of the prevailing bias. In this essay, I discuss the implications of these problems for the conduct and interpretation of research.

Only seven weeks after his trip, Trump ran full-page ads in the Boston Globe, the NYT and WaPO calling for, in effect, the dismantling of the postwar Western foreign policy alliance. The whole Trump/Russian connection started out as laundering money for the Russian mob through Trump's real estate, but evolved into something far bigger. ► In 1984, David Bogatin — a Russian mobster, convicted gasoline bootlegger, and close ally of Semion Mogilevich, a major Russian mob boss — met with Trump in Trump Tower right after it opened. Bogatin bought five condos from Trump at that meeting. Those condos were...
