Sometimes, when researchers are conducting an experiment, the results are confusing. Maybe the control group of animals doesn’t behave the way a control should in theory be behaving. Maybe a researcher repeats a study and sees results that are unusually different from the first time around. The answers to these issues might lie in something called ‘hidden variables,’ according to a new study titled, “What’s wrong with my research? The impact of hidden variables on neuropsychopharmacology research.”

Brian Trainor is a professor of psychology at the University of California Davis, and he’s one of three authors of the study. His co-authors are Amanda Kentner, professor at the Massachusetts College of Pharmacy and Health Sciences, and Hannah Butler-Struben, a graduate student in the animal behavior group at UC Davis. They say that many of the articles in the review are from journals about animal behavior that wouldn’t typically come across the desk of those working in the field of neuroscience.
