Psychology - the 36 percent replication problem

"Despite this careful planning, less than half of the replication studies reproduced the original results. While 97 percent of the original studies produced results with a “statistically significant” p-value of 0.05 or less, only 36 percent of the replication studies did the same." (cf. "Psychology Is Starting To Deal With Its Replication Problem", Christie Aschwanden in FiveThirtyEight - August 27, 2015)
