Everything we “know” is retrospective. Humans have unlimited hindsight but limited foresight. This is most apparent in the preoccupation with counting injury statistics. Statistics in themselves don’t tell us the “story” of what they mean; significance is subjectively determined.
People make mistakes; it’s what makes us human. The propensity for human error is practically embedded in our DNA. While the idiom holds that there is no use crying over spilled milk, might there not be some benefit in examining the causes, contributors, and catalysts associated with poor decision-making?
