Does it help to record everything that happens to you?

Recording everything produced huge archives and nothing useful

Sellen & Whittaker (2010) · Communications of the ACM

Illustrative — the direction is the finding. A decade of lifelogging research, reviewed.

Total capture produced enormous archives and no compelling applications. The authors’ prescription: design from the psychology of human memory, support the five Rs — recollecting, reminiscing, retrieving, reflecting, remembering intentions — and work with human memory rather than trying to replace it.

How it was done

A critical review of a decade of lifelogging research, assessing what wholesale capture systems actually delivered against what they promised.

What it means

The failure was not technical. The systems captured successfully. What they could not do was make the resulting archive worth opening, and an archive nobody opens is indistinguishable from no archive.

The prescription is a design constraint: capture selectively, cue rather than replace, and be able to say which of the five Rs each feature actually serves.

Fifteen years on, the same failure mode is available to anyone building capture tools with cheaper storage and better transcription. Neither of those was the bottleneck.

What it doesn’t show

A critique and a research agenda rather than an experiment — it reports no effect size and tests no system. It also predates modern transcription and retrieval, which changes what is buildable even if it does not change the argument about what is useful.

What Kept does about it

It is the reason Kept captures a few seconds of what you noticed rather than everything you could record, and the reason the resurfacing loop matters more to us than the capture step.

Confidence: B — a single strong peer-reviewed study, or a consistent multi-study literature. We don’t publish anything weaker than this.

Kept is what we built from this.

A private voice journal for the people closest to you. Nine seconds of talking after you see someone, and the detail comes back before it matters.
