The Dunning–Kruger effect is a cognitive bias manifesting in unskilled individuals suffering from illusory superiority, mistakenly rating their ability much higher than is accurate. This bias is attributed to a metacognitive inability of the unskilled to recognize their ineptitude.
No interest to go into massive detail here. I prefer to apply this to reality and You can have a look in the WWW for more scientific details and also experiments that guys conducted.
This effect can be really well applied to HR and talent acquisition. How will you ask? HR people need to keep in mind the attitude of qualified and unqualified interview takes regarding their skills and expertise.
Interesting fact about less qualified people (prefer to call this way rather saying unqualified. I really believe everyone has skills and qualifications and talent as well):
- those people have tendency to overestimate their skills and experience
- they can't adequately value the skills and experience level of other people
- people of this kind can't really understand their own incompetency
- however in case one can lift up their competency level, they are able to understand how incompetent they were before
Make sure to hire the right ones and recognize talent! :)
