Psychology Desperately Needs a Massive Influx of Skepticism
By Lee Jussim Ph.D.
Skepticism is crucial for good science in a way that has some similarities to why removing weeds is crucial for a healthy garden. Bad weeds can choke off healthy plants; bad science can choke off good science if, like a runaway weed, sometimes, bad science becomes popular, highly funded, and adopted as a basis for law, social policy, and personal use. It then takes away attention and resources from good science and leads to impressive promises of personal and social change that end up as dead ends, or worse.
Even plants that have some value like scientific claims that have some truth but are wildly oversold can mostly function as weeds, if they go too far. Consider ivy that covers windows and doors; bamboo that takes over a yard; and scientific claims that have some truth but are wildly oversold.
Science has a long history of bad weeds, everything from bad astronomy theories choking off good ones to bad medicine. Social psychology has a disturbingly impressive track record of such “weeds,” including social priming, the power of the situation, stereotype threat, implicit bias, ego depletion, power posing, stereotype inaccuracy, stereotype bias, grit, delay of gratification, the Stanford Prison Experiment, facial feedback, and more (and more and more).
