The well known Dunning-Kruger effect is oft cited as a general explanation for why people with limited expertise overestimate their abilities. Other than the initial research that described this cognitive bias, there seems to be little actual data to support it outside of a sit-down questionnaire or IQ test in a university setting. Driving is a well-known example (i.e. '80% of drivers consider themselves above average') although I note from a previous post, the evidence for the Dunning-Kruger effect in driving is mixed.
Is there any data to support the Dunning-Kruger in outside of a sit-down test performed by university students?
