Metacognition:
Knowledge about the accuracy of our knowledge is a facility called metacognition. Requiring self-awareness and introspective judgements, it is used in many everyday decisions. For instance, we might decide to invest money in a new venture because it seems promising, but choose not to risk much capital because we realise we might be mistaken. [“We can train ourselves to be better at knowing when we are wrong“, Clare Wilson, NewScientist (1 September 2018, paywall)]
