Among more than 300 other psychology and medical journals, Evolution and Human Behavior has adopted result-blind peer review (i.e. where studies are accepted not on the basis of their findings and after the studies are completed, but before the studies are conducted and upon the basis of the methodological rigor of their experimental designs and the theoretical justifications for their statistical analysis techniques before data collection or analysis is done) as part of an initiative organized by the Center for Open Science in response to concerns about the replicability of experimental findings in the sciences and medicine, publication bias, and p-hacking.[1][2] Early analysis of such reforms in psychology journals has estimated that 61 percent of result-blind studies have led to null results, in contrast to an estimated 5 to 20 percent in earlier psychological research.[3]
