Resident physicians instructed to be "careful, thorough, and reflective" when answering clinical vignette questions took 30% more time with each case but did not have better diagnostic accuracy compared with residents who were told to answer as quickly as possible. These results suggest diagnostic errors are not simply related to insufficient attention or time.
