> 2011: Joseph Simmons, Leif Nelson, and Uri Simonsohn publish a paper, “False-positive psychology,” in Psychological Science introducing the useful term “researcher degrees of freedom.” Later they come up with the term p-hacking, and Eric Loken and I speak of the garden of forking paths to describe the processes by which researcher degrees of freedom are employed to attain statistical significance.
