A selection9 of cognitive biases originally described by Croskerry

Confirmation biasLooking for evidence to support a preconceived opinion, rather than looking for information to prove oneself wrong
Diagnosis momentumAccepting a previous diagnosis without sufficient scepticism
Framing effectMaking a decision based on the positive (or negative) way in which situation presented
Overconfidence biasOver-reliance on one’s own ability, intuition and judgement
Premature closureSimilar to ‘confirmation bias’ but more ‘jumping to a conclusion’
Self-satisfying biasThe ‘eureka’ moment that stops all further thought
