Is Most Published Research Wrong? The You Tube

This You Tube video, from the channel Veritasium, is a compendium of studies, anecdotes, and initiatives addressing key problems in scientific research.  It includes a compact summary of John Ioannides’ famous paper, “Why Most Published Research Findings Are False“, studies that were published and shouldn’t have been (such as a recent study showing that eating chocolate causes weight loss), the story of the pentaquark — the sub-atomic particle that wasn’t, the research exercise on whether dark-skinned soccer players get red-carded more frequently, a nice discussion of p-hacking, and Brian Nosek’s famous aphorism: “There is no cost to getting things wrong.  The cost is not getting them published.”  All compressed in 12 minutes.  Check it out here.
