Why Investigators Should Record Their Reasoning, Not Just Their Conclusions

A piece published on DEV Community argues that investigative work consistently fails to preserve the analytical reasoning behind conclusions, even as physical evidence is meticulously archived. The author observes that when two investigators disagree, teams typically debate outcomes rather than tracing where their thinking first diverged. Drawing an analogy to software version-control diff tools, the author suggests that recorded reasoning could be compared the way code changes are — showing precisely where two analytical paths parted. Different investigators naturally apply different thinking habits, and the author frames this cognitive diversity as valuable information rather than a problem to resolve. The core proposal is that preserving the route of reasoning, not just the final report, would make disagreements easier to diagnose and independent analysis more meaningful.
