The Dunning-Kruger cognitive bias suggests that if you have expertise or competence in a subject, you’re more likely to play down your capabilities than boast of your brilliance. Unfortunately, the reverse is also true. Low ability individuals massively over estimate their abilities in areas they know nothing about. We’ve all come up against this in real life, whether around the dinner table or when people in public life make bold statements about what is essentially unknowable i.e the future.
It feels to me that we all need to be on the look out for the impact of this simple cognitive bias. We live in a world where experts are ‘discredited’ and the ‘man in the street’ knows best. Dunning-Kruger suggests otherwise.
