This inversion technique reveals a crucial truth: failure tends to cluster around a limited set of predictable mistakes. Evolution, too, operates by eliminating what doesn't work rather than pinpointing perfection. Natural selection discards genetic variations that fail to reproduce, leaving behind resilient, though not necessarily optimal, traits.
In medicine, this is reflected in the emphasis on pathology—knowing what goes wrong with the body is more practical than always searching for ideal health. Recognizing the multitude of ways the kidneys can fail is more actionable than knowing a single point of perfect health. This negative knowledge often surpasses positive insights in utility, as understanding weakness is vital for prevention and correction.
