![]() ![]() “When they’re unskilled, they can’t see their own faults. “The result is that people, whether they’re inept or highly skilled, are often caught in a bubble of inaccurate self-perception,” Addison explained. But they often make a different mistake: They assume that everyone else is knowledgeable too.” “They know enough to know that there’s a lot they don’t know.”īut knowledge can also lead to people overestimating others: “Experts tend to be aware of just how knowledgeable they are. “That may be why people with a moderate amount of experience or expertise often have less confidence in their abilities,” Addison said. But some level of experience or expertise is needed for a person to come to that realization. The good news is once people know they are bad at something - say, if they fail at a logic puzzle - they’ll typically admit to it. In other words, poor performers lack the very expertise needed to recognize how badly they’re doing.”įor example, how can someone know he’s a bad writer if he doesn’t know even basic spelling and grammar rules? But second, those same knowledge gaps also prevent them from catching their errors. First, they make mistakes and reach poor decisions. ![]() So what’s going on here? There’s actually a reasonable explanation: “When psychologists Dunning and Kruger first described the effect in 1999, they argued that people lacking knowledge and skill in particular areas suffer a double curse. This is true “to a degree that violates the laws of math.” For example: “When software engineers at two companies were asked to rate their performance, 32 percent of the engineers at one company and 42 percent at the other put themselves in the top 5 percent.” In fact, we frequently overestimate our own abilities.” ![]() “But,” Anderson added, “psychological research suggests that we’re not very good at evaluating ourselves accurately. “It helps us figure out when we can forge ahead on our own decisions and instincts and when we need, instead, to seek out advice.” “Knowing how competent we are and how our skills stack up to other people’s is more than a self-esteem boost,” narrator Addison Anderson explained. This can not only be really annoying, but it can lead to disaster as a group project is made much more difficult by someone’s unchecked ego.Ī new TED-Ed video, based on a lesson by psychologist David Dunning, dives into why this happens and why people are so bad at judging their skills in general, looking into the phenomenon known as the Dunning-Kruger effect. Maybe you’ve experienced this at school or work before: Dealing with someone who thinks he’s much better at his job than he really is. ![]()
