Which fallacy suggests that a small first step will inevitably lead to a chain of related (and often negative) events?

The choice of "slippery slope" is correct because this fallacy posits that an initial, relatively minor action can trigger a sequence of events that lead to significant and often dire consequences. It relies on the assumption that once a certain action is taken, it will set off a chain reaction that cannot be stopped, leading to negative outcomes. This type of reasoning is often used in debates to exaggerate the potential impact of a minor decision, making it seem like a dire threat without providing evidence for the inevitability of such a progression.

Understanding this concept is crucial, as it reflects a logical error that can oversimplify complex situations by disregarding the possibility of intervening factors or alternative outcomes. This fallacy can weaken arguments by creating a fear-based rationale rather than a sound, evidence-based one. The slippery slope fallacy illustrates how fears of extreme consequences can be invoked without substantiating the connection between the steps in question.
