Shelf life of a thought: the rate at which a thought decays
Shelf life of a thought: the rate at which a thought decays and becomes unrecoverable, which varies from minutes for contextual insights to weeks or permanent for reference facts
Why This Is a Definition
This definition precisely establishes the semantic boundary of 'shelf life' by specifying that it's about decay rates and unrecoverability, then categorizes the different rates (flash, short, medium, stable) with clear distinctions that distinguish it from general memory concepts or forgetting curves.
