The hijackers of flight 961 wanted its pilot to fly them to Australia – and wouldn’t listen to his pleas that there simply wasn’t enough fuel for the mammoth trip. What would cause them to totally disregard the advice of an expert when the stakes were so very high? The Dunning Kruger effect.
But being too stupid to recognise the limits of your knowledge isn’t confined to such prize idiots – it’s something we are all guilty of at times and has huge implications for society.
