Crusoe index,

the probability of a (more or less literally) naked adult human to survive in wild nature — alone and without access to anything artificial. Usually it is extrapolated from estimates — assuming a spatially and temporally local wilderness — to all of Earth, excluding anything man-made but with oceans, mountains, deserts weighed in proportional to their area. Space Crusoe index redefines the concept for a human, sans spacesuit or spaceship of any sort, in a random point of observable cosmos; currently its indistinguishable from zero but that may change.  ■    “Back when human life was a permanent Crusoe evaluation,” bare physical survival — diseases, famines, predators — dominated the value and kept it well below unity; it is commonly believed that throughout historical times, the index — a function of the changing state of the environment as much as of the changing human — was gradually decreasing (with some upshots), reaching its minimum in early modernity, but has been on the rebound since. It may now be at its historically highest point (above 0.5 by some estimates); much of that is new humans bodily strength — though its just easier to survive on todays gardened Earth. Psychological sustainability — including solitude tolerance, allegedly from adaptations to societal sparsening and atomization — has overshadowed material subsistence; imagine a cosmic-leaping Leaver whose ship has everything (including a static copy of Knowledge) but who cant return or communicate, even one-way, with Earth: how much of a standalone micro-civilization are you?
