Social scientists know which research is bunk

For the past decade or so, social science has been grappling with a replication crisis; too many experiments, when repeated by other scientists<https://ted.us1.list-manage.com/track/click?u=07487d1456302a286cf9c4ccc&id=d4cf3ea01a&e=c4c4e0a281>, don't yield the same results that the original scientists published. Recently, a group of researchers replicated 21 social science experiments<https://ted.us1.list-manage.com/track/click?u=07487d1456302a286cf9c4ccc&id=b01688445f&e=c4c4e0a281> from two prestigious journals between 2010 and 2015 -- with a twist: they used a prediction market<https://ted.us1.list-manage.com/track/click?u=07487d1456302a286cf9c4ccc&id=2835dff8bc&e=c4c4e0a281> to ask other scientists which experiments they predicted would fail. The good news? Thirteen of the studies did in fact replicate<https://ted.us1.list-manage.com/track/click?u=07487d1456302a286cf9c4ccc&id=3f2d405573&e=c4c4e0a281>. The better news? The peer scientists accurately predicted<https://ted.us1.list-manage.com/track/click?u=07487d1456302a286cf9c4ccc&id=2d9157ded6&e=c4c4e0a281> which experiments would fail to replicate. As the analysis puts it: "failures to replicate were not the result of chance alone<https://ted.us1.list-manage.com/track/click?u=07487d1456302a286cf9c4ccc&id=51b2250ac7&e=c4c4e0a281>."
