    • “Winner Takes All” Incentives“The winner-take-all aspect of the priority rulehas its drawbacks, however.

    • How Often Are Medical Studies Wrong?
    • Does The Literature Reflect Reality?
    • Does The Literature Reflect Reality? Publish a trial that will bring US$100,000 of profit or meet the end-of-year budget by firing an editor. -- Former BMJ editor Richard Smith
    • Positive Publication Bias
    • Positive Publication Bias“The overall frequency of positive supports has grown by over 22% between 1990 and 2007, with significant differences between disciplines and countries.”“…the strongest increase in positive results was observed in disciplines—like Clinical Medicine, Pharmacology & Toxicology, Molecular Biology” Fanelli, Scientometrics 2012.
    • Publish All Data?
    • Publish All Data? www.AllTrials.net
    • FDA: “Black-or-White Approval”
    • FDA: “Black-or-White Approval”“…abandon the current black-or-white approvalprocess in favor of an incremental, conditional one.In such a process, drugs could be provisionallyapproved after promising early-stage data, with theFDA retaining the option to revoke that approvallater on, should unexpected data come to light.”“A ‘conditional approval’ approach would grantlimited marketing authorization to new drugs aftersuccessful Phase II trials.” http://www.manhattan-institute.org/
    • Confirmation Biases“Facts do not accumulate on the blank slates ofresearchers minds and data simply do not speak forthemselves. Good science inevitably embodies atension between the empiricism of concrete dataand the rationalism of deeply held convictions.”“…awareness of the systematic errors that can occurin evaluative processes may facilitate the selfregulating forces of science and help producereliable knowledge sooner rather than later.” -- Kaptchuk, BMJ, 2003;326:1453–5
    • Believers vs. Snails -- Kaptchuk, BMJ, 2003;326:1453–5
