Is bias in the eye of the beholder? A vignette study to assess recognition of cognitive biases in clinical case workups.
Approach to Improving Safety
Setting of Care
Providing eight ambiguous clinical vignettes to generalist physician members of the Society to Improve Diagnosis in Medicine, this study found participants did not agree on whether cognitive biases were or were not present. When the outcome of the vignette implied an incorrect diagnosis, respondents reported twice as many biases, suggesting that physician judgments are strongly influenced by hindsight bias.
