Core Cognition

In 1999, Justin Kruger and David Dunning wrote a paper called “Unskilled and Unaware of It: How Difficulties in Recognizing One’s Own Incompetence Lead to Inflated Self-Assessments”. They noted that “People tend to hold overly favorable views of their abilities in many social and intellectual domains”. Because of this they “reach erroneous conclusions and make unfortunate choices”. This makes sense: if you overestimate your abilities, at some point reality will prove you wrong and you will suffer unexpected and generally unfortunate consequences.

You may have wasted your own or other people’s time, but it may also entail that you seriously harm yourself or others.

What Kruger & Dunning “discovered” is that people with low levels of domain competence tend to exhibit an equally low level of the metacognitive abilities to realize they are incompetent: they are “unskilled and unaware of it”. Hence, they judge their competence as adequate or good, while they are still pretty incompetent. While this is a unfortunate on an individual level, it may be disastrous on a societal level. Especially if policy makers, managers, and in general authorities, overestimate their abilities and remain completely unaware of this, even in the face of utterly failing policies. This lead to wasted resources at best and widespread harm and destruction at worst.

Progressing to mastery

The way the Kruger-Dunning effect manifests itself during learning is straightforward. When you do not know anything about a topic you rate your competence as low. Most knowledge acquisition starts – rapidly and without much effort – with the adoption of an informative and explanatory narrative from an authority figure. This is the first step of knowledge and skill acquisition. Initially you need to hear the narrative a few times, but soon you become proficient in the explanatory narrative: you know the narrative components and can predict what will come. This is also the moment that you can formulate the narrative independently, which gives a sense of mastery: you mastered the narrative, you can give the proper answers within the new knowledge domain, and you now have a basis of confidence.

At the same time you still lack insight in the real-world aspects of applying the just acquired knowledge. Lacking this insight, you are at peak confidence, you think the real-world application of your new (narrative level) knowledge is simple, straightforward, and even obvious.

Here we use the Kruger-Dunning effect to show what happens if you do not acquire real-world comptences and instead get stuck in a narrative or ideology that you take, by default as true, because you avoid testing it in the real world.
