The relationship between doctors' medical knowledge and their inability to assess correctly what they know was investigated. Sixty out of 65 hospital physicians sat a MRCP Part 1 multiple-choice examination. In addition to the factual questions, they had to estimate how certain they were that their answers were correct. We confirmed that factual knowledge increased with clinical experience from the grade of house officer through to that of senior registrar. The self-assessment of likelihood of being correct revealed that, on average, doctors underestimated their knowledge by 8%. However, those who had passed their MRCP examination within the past three years over-estimated on average by 6%. We suggest that this inadequacy of self-assessment could have serious clinical implications, and should be assessed.
研究了医生的医学知识与其无法正确评估自身所知之间的关系。65名医院医生中的60人参加了内科医师考试第一部分的多项选择题考试。除了事实性问题外，他们还必须估计自己对答案正确的确定程度。我们证实，从住院医师级别到高级专科住院医师级别，实际知识随着临床经验的增加而增长。对答案正确可能性的自我评估显示，医生平均低估了自己的知识8%。然而，那些在过去三年内通过内科医师考试的人平均高估了6%。我们认为，这种自我评估的不足可能会产生严重的临床影响，应该进行评估。
