The "domino effect" refers to a chain reaction where one event triggers a series of related events. This concept is often illustrated using a line of standing dominoes; when one is knocked over, it causes the next one to fall, and so on. The effect can be seen in various contexts, such as economics, social behavior, and environmental changes. In a broader sense, the domino effect highlights how interconnected systems can influence each other. For example, a small change in policy can lead to significant shifts in public opinion or market trends. Understanding this effect helps in predicting outcomes and managing complex situations.
