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.

Has anyone heard any tales about someone doing a conference or seminar, setting up their laptop, and having porn or something similarly embarrassing accidentally come up on the big screen? It's gotta have happened. I've tried searching Usenet but it's a tough cookie to do keywords for.
