^ Uri Simonsohn, Leif D. Nelson, Joseph P. Simmons (24 April 2013), “P-Curve: A Key to the File Drawer”, in Journal of Experimental Psychology: General, Forthcoming, volume 143, number 2, →DOI, page 534:

While collecting and analyzing data, researchers have many decisions to make, including whether to collect more data, which outliers to exclude, which measure (s) to analyze, which covariates to use, and so on. If these decisions are not made in advance but rather are made as the data are being analyzed, then researchers may make them in ways that self-servingly increase their odds of publishing (Kunda, 1990). Thus, rather than placing entire studies in the file-drawer, researchers may file merely the subsets of analyses that produce nonsignificant results. We refer to such behavior as p-hacking.
