Aaron Miedema linked to this BBC article about the link between diminished self-awareness and incompetence:
Psychologists have shown humans are poor judges of their own abilities, from sense of humour to grammar. Those worst at it are the worst judges of all.
You’re pretty smart right? Clever, and funny too. Of course you are, just like me. But wouldn’t it be terrible if we were mistaken? Psychologists have shown that we are more likely to be blind to our own failings than perhaps we realise. This could explain why some incompetent people are so annoying, and also inject a healthy dose of humility into our own sense of self-regard.

Kruger and Dunning’s interpretation is that accurately assessing skill level relies on some of the same core abilities as actually performing that skill, so the least competent suffer a double deficit. Not only are they incompetent, but they lack the mental tools to judge their own incompetence.
In a key final test, Kruger and Dunning trained a group of poor performers in logical reasoning tasks. This improved participants’ self-assessments, suggesting that ability levels really did influence self-awareness.
Other research has shown that this “unskilled and unaware of it” effect holds in real-life situations, not just in abstract laboratory tests. For example, hunters who know the least about firearms also have the most inaccurate view of their firearm knowledge, and doctors with the worst patient-interviewing skills are the least likely to recognise their inadequacies.
What has become known as the Dunning-Kruger effect is an example of what psychologists call metacognition — thinking about thinking. It’s also something that should give us all pause for thought. The effect might just explain the apparently baffling self belief of some of your friends and colleagues.
