Organize the task, not a test of cognition
A task difficulty describes what happened; it does not measure cognition or establish safe performance.
| Task or change | What it does not establish |
|---|---|
| Brief lapse in a low-consequence task | One lapse and a quit date do not diagnose impairment or prove withdrawal. |
| Complex task has too many steps | Feeling overloaded does not show memory loss or determine a medical cause. |
| Money, legal or irreversible decision | Confidence, urgency or a webpage is not an accuracy check. |
Organize the task, not a test of cognition
Separate attention lapses from memory problems, sleepiness, dizziness and low mood. Similar words can require different next actions.
A task checklist is useful only if it changes the task. Fictional example: split a routine email into reading, drafting and one check. Completing it does not establish normal cognition or safe driving. For a consequential task, decide beforehand whether another person can check or take over; reading a checklist twice cannot substitute for that handoff. For an ordinary task, reduce nonessential interruptions where practical.
Check what else changed
Poor sleep, stress, task overload, medicines and another health issue can all affect concentration; the quit date cannot identify which one is responsible.
When an attention change affects tasks or safety
A sudden, severe, persistent or safety-affecting attention change needs prompt local assessment rather than being assumed to be withdrawal. Do not drive, use machinery, work at height or continue another safety-critical task when alertness, attention or self-control is unreliable. Follow the stricter local workplace or road rule.
