Open loop
an active mental representation of an incomplete task or commitment that continuously consumes working memory and creates cognitive tension until externalized into a trusted system
Why This Is a Definition
This definition precisely captures the semantic boundary of 'open loop' by identifying its genus (active mental representation) and differentia (of incomplete task/commitment, continuously consuming working memory, creating cognitive tension). It distinguishes it from general memory or attention issues by specifying the functional mechanism (consumes working memory, creates tension) and the resolution condition (externalization into trusted system). The definition directly maps to Zeigarnik's research and the lesson's emphasis on the cognitive burden of unexternalized commitments.
Source Lessons
Reliable capture creates cognitive freedom
When you trust your capture system your mind stops trying to hold everything.
Context switching has a hidden cost
Every time you switch tasks, you pay a recovery tax — between 10 and 25 minutes of degraded cognition while your brain reloads the previous context. This cost is invisible because you feel busy the entire time.
Context switching requires context loading
When you change contexts you must deliberately load the relevant frame of reference.
Inbox zero for thoughts
A single inbox that you process regularly prevents thoughts from being trapped in random places. The inbox is not storage — it is a waystation. Everything enters. Nothing stays.
Notification audit
Every notification you allow is an attention tax — audit ruthlessly.
Externalize your commitments
An unwritten commitment is an invitation for your future self to renegotiate. Externalized commitments become binding infrastructure — visible, trackable, and resistant to the drift that lives between intention and action.
