Here’s a recent podcast of mine about the Dunning Kruger Effect. It’s a useful phenomenon to be aware of when leading different types of people, especially when needing to give performance feedback of any kind. There are two sub-groups of people who are least accurate at assessing their own levels of performance: the very excellent and the very non-excellent. Most people are average or either side of it and their self-assessments are ‘there or thereabouts.’ The high performers become high performers because they underestimate how good they are (or should / could be) and try harder and smarter as a result. AND they continue to improve through deliberate and focused practice built on feedback.
The best illustration of the other end of the scale where poor performers never improve because they either never receive feedback (or effective feedback) or they are closed to it are the auditioners for any of those Idol-type shows where security has to escort them off the premises. They characterise perfectly the Dunning Kruger Effect. They simply cannot believe they’re being told “No” and that they’re not the next Mariah. Their dramatic OTT response is great for these shows and symptomatic of why they’re never going to get any better without a substantial external intervention in their lives. Or never. How many of these people have you worked with over your career? Here’s John Cleese’s interpretation.
All sweeping generalisations but an interesting lens through which to look at your team.
