Blink or think: can further reflection improve initial diagnostic impressions?
Hess BJ, Lipner RS, Thompson V, et al. Blink or think: can further reflection improve initial diagnostic impressions? Acad Med. 2015;90(1):112-118. doi:10.1097/ACM.0000000000000550.
This direct observation study examined cognition among experienced clinicians in the setting of their recertification examination and found that when they changed answers, it was usually from an incorrect to a correct response. This suggests that further reflection enhances accuracy compared to intuitive response, consistent with work on metacognition to enhance diagnostic accuracy.
