“High-impact journals often regard psychology as a sort of parlour-trick area,” says [Chris Chambers, an experimental psychologist at Cardiff University, UK]. Results need to be exciting, eye-catching, even implausible. Simmons says that the blame lies partly in the review process. “When we review papers, we’re often making authors prove that their findings are novel or interesting,” he says. “We’re not often making them prove that their findings are true.”
Simmons should know. He recently published a tongue-in-cheek paper in Psychological Science ‘showing’ that listening to the song When I’m Sixty-four by the Beatles can actually reduce a listener’s age by 1.5 years. Simmons designed the experiments to show how “unacceptably easy” it can be to find statistically significant results to support a hypothesis.
Lang, maar erg interessant artikel op de Nature-site van wetenschapsjournalist Ed Yong over hoe lastig het is binnen de psychologie om onderzoek gepubliceerd te krijgen waarbij is geprobeerd eerdere experimenten te reproduceren, met name als dat niet is gelukt. Met een alineaatje over ‘onze’ Diederik Stapel.
