Which option illustrates a slippery slope fallacy?

• A. If we allow this policy, next we’ll be overwhelmed by endless regulations.
• B. We could consider several alternative approaches.
• C. There is evidence supporting mixed outcomes.
• D. Implementing this policy might have mixed consequences.

Answer: (A)

A slippery slope fallacy happens when an argument claims that a small first step will inevitably lead to a chain of events resulting in a dramatic, undesirable outcome, without solid evidence that the chain will actually occur. The option in question says that allowing this policy will lead to endless regulations. That assertion draws a direct line from a single action to an extreme future, treating the outcome as guaranteed rather than as a possible, but uncertain, consequence. It relies on fear of a worst‑case scenario rather than a justified causal link, which is the essence of a slippery slope.

The other statements present reasonable or balanced views: one calls for considering several alternatives, another notes that there is mixed evidence, and the last acknowledges mixed consequences. None of these imply an inevitable cascade from a single decision, so they don’t illustrate the slippery slope pattern.
