Seems the z-axis to the equation here would be the relevant frequency of occurrence.
ie - My parents leave their garage and boat house doors open all day, every day. They've yet to have a single thing stolen, that they know of, in their little Mayberry town where this kind of thing is very rare. All the same, I've been working in my garage before when a stranger I don't know as a neighbor walked in, picked something up, then dropped it and took off running when I came rising from behind my work bench in a town notorious for this kind of crime.
If I left my garage or shop open and something came up missing, I think it's fair to assign some blame to my own negligence given the frequency of occurrence in my town. It doesn't seem to equate the same assignment of blame for my parents as it is very rare in theirs.
I guess the real question in assigning a shared blame might be queued in the statistics of whatever town this happened in.
