The Oh, Shit! Factor is just the opposite: unknown unknowns that arise out of nowhere (i.e. the external environment) that always seem to bite you in the ass at the most inopportune time, and these are the little “pleasantries” that Murphy (of Murphy’s Law infamy) likes to throw at us. Planning on going to work early but your car doesn’t start? Oh, shit! Bought a ridiculously overpriced house because of a promised year-end bonus that never materialized? Oh, shit! In a firefight and your weapon jams? Oh, shit! You get the idea.
