(adj.) Describing an event that occurs within a temporal sequence but produces no causal, material, or narrative consequence on the external world’s subsequent state — the world unfolds identically to how it would have if the event had never happened.
Distinct from inconsequential: nullsequential is a structural, causal claim about whether an event propagates forward into outcomes, while inconsequential is a subjective claim about whether an event carries internal or felt weight. The two properties are independent, producing four possible combinations for any given event:
- Nullsequential + inconsequential — no forward causal thread, no internal charge (e.g., what you had for lunch three Tuesdays ago)
- Nullsequential + consequential — no forward causal thread, but real internal charge (e.g., a work presentation that won’t affect your career but still costs you ego)
- Sequential + inconsequential — real forward causal thread, but no felt weight (e.g., a routine email that quietly triggers decisions above your head)
- Sequential + consequential — real forward causal thread and real felt weight
Antonym: sequential.
