The Dunning-Kruger Effect Shows that People Don’t Know What They Don’t Know

The Dunning-Kruger effect describes a disturbing cognitive bias that afflicts us all. People with limited expertise in an area tend to overestimate how much they know—and we all have gaps in our expertise. That disconnect may explain why some patients turn to "Dr. Google" to make at-home diagnoses of complex medical problems, as well as the missteps we all make from time to time, from fixing the plumbing to representing ourselves in a court of law.

On any particular topic, people who are not experts lack the very expertise they need in order to know just how much expertise they lack. The Dunning-Kruger effect visits all of us sooner or later in our pockets of incompetence. They’re invisible to us because to know that you don't know something, you need to know something. It’s not about general stupidity. It’s about each and every one of us, sooner or later.

You can be incredibly intelligent in one area and completely not have expertise in another area. We all know very smart people who don't recognize deficits in their sense of humor or their social skills, or people who know a lot about art but may not know much about medicine. We each have an array of expertise, and we each have an array of places we shouldn't be stepping into, thinking we know just as much as the experts.

By stimulating the ear’s hearing and balance systems, Soundsory activates countless brain connections. Together, the ear and brain are retrained to process sensory information more quickly and accurately for better balance, coordination, and motor skills.

Soundsory inherits years of research and technological development thanks to the Tomatis® Method, a neurosensory stimulation technique used at 2,000+ institutes in 70+ countries originating from numerous scientific studies.
