Definition
Uncompleted or interrupted tasks are remembered far better than completed ones - the brain keeps "open loops" active in working memory until they are resolved. The mechanism behind the anxiety cost of procrastination, the compulsion to finish TV series and why cliffhangers are effective.
When it shows up
Interrupted tasks, unresolved conversations, unfinished projects. Any open loop the mind cannot close. Especially before sleep.
Failure mode
The uncompleted task generates intrusive cognition until it is either completed or explicitly parked. Attention is pulled back to the open loop at cost to whatever is currently happening.
Countermeasure
Write the next concrete step for the open task and commit to a time to do it. The mind treats a scheduled-and-written next step as a form of partial closure, releasing the attentional grip.
