Principle
Prune noisy alerts before adding another one
More warnings can make the important warning harder to hear.
When it fits
- People ignore, mute or delay responses to a notification channel that contains many false, duplicate or low-value alerts.
When to avoid it
- Do not optimize only for low alert count. Rare high-consequence alerts may deserve strong interruption even if they are inconvenient.
Why it matters
Treat attention as a limited system resource. Measure which alerts are actionable, duplicated, stale or routinely dismissed; then remove, combine, delay or downgrade the low-value ones before adding more. Review the misses as well as the volume: a quiet channel that hides critical states is not an improvement. The goal is higher signal value, not simply fewer messages.
An example
If a CI channel posts every successful retry and every transient warning, group the routine noise and preserve immediate interruption for states that need human intervention.
Check your result
The alert set becomes smaller or better grouped while retaining a clear path for genuinely time-sensitive states.
Keep this limit in mind
- Do not optimize only for low alert count. Rare high-consequence alerts may deserve strong interruption even if they are inconvenient.

Evidence and sources
AHRQ PSNet describes alarm fatigue as slower or absent response when people are repeatedly exposed to alarms that are invalid or nonactionable.
The cited evidence is clinical; notification fatigue in software can share the attention mechanism without having the same risk magnitude.
Ten years later, alarm fatigue is still a safety concern · Summary
AHRQ's alarm-safety summaries emphasize reducing nonactionable alarms and improving the usefulness and prioritization of alerts rather than simply adding more alerts.
The correct alert threshold and modality depend on the task, consequence and user environment.
