Rebuilding after the replication crisis

A Dutch psychology professor, Diederik Stapel, was found to have faked dozens of studies across many years, and nobody had noticed, in part because barely anyone had tried to replicate his work (and in part because it's really awkward to ask your boss if he's made up all his data). Psychologists published a provocative paper that showed that they could find essentially any result they wished by using statistics in biased ways — ways that were almost certainly routinely used in the field. And one of those hen's-teeth replication attempts found that a famous study from "social priming," the same social psychology genre as the cardboard box study — in which merely seeing words relating to old people made participants walk more slowly out of the lab — might have been an illusion. Similar stories followed.
