The Dunning-Kruger effect and the muesli bar: Those who know the least tend to believe they are highly competent
The Dunning-Kruger effect can be observed in many different areas: Those who know the least often think of themselves as particularly competent, while those with a lot of knowledge tend to underestimate their own expertise. A research team recently investigated the extent to which this phenomenon can be observed in the area of media and nutrition. The results are clear: Even when it comes to evaluating a supposedly healthy low-carb bar, people who are not competent at all consider themselves to be particularly competent.
