Cover Story: The well-known Dunning–Kruger effect states that people with low skills in a domain tend to overestimate the very same skills. While Dunning–Kruger effects have been shown for a multitude of abilities (including intelligence), this work has also been criticized. We revisited the Dunning–Kruger effect for (verbal, numerical, spatial, and general) intelligence using standard—and often criticized—statistical analyses as well as recently proposed alternatives. While standard analyses broadly indicated Dunning–Kruger effects, improved statistical methods only yielded some support for one in verbal intelligence: people with lower verbal intelligence tended to have less self-knowledge about it. Our results contribute to a growing literature questioning the generality of the Dunning–Kruger effect. View this paper
