When is an individual most likely to make a serious mistake (say, on the job or at some task involving risk)? I recall research that suggesting a "seven year rule" that after seven years of doing something, one has acquired enough mastery over the job or task or skill that complacence begins to creep in -- and with it, vigilance drops and disaster ensues. Any leads much appreciated.
