>[!abstract] >A domino effect is the cumulative effect produced when one event sets off a series of similar or related events, a form of chain reaction. The term is an analogy to a falling row of dominoes. It typically refers to a linked sequence of events where the time between successive events is relatively short. The term can be used literally (about a series of actual collisions) or metaphorically (about causal linkages within systems such as global finance or politics) (Wikipedia, 2025). >[!related] >- **North** (upstream): — >- **West** (similar): [[For want of a nail]] >- **East** (different): — >- **South** (downstream): —
