Best practice
Support your use of the metaphor with logical evidence to explain why the subsequent steps are likely to occur, rather than just asserting they will.
Common error
Do not use "slippery slope" as a substitute for a reasoned argument. If you claim an action will lead to disaster without showing the intermediate links, your argument may be dismissed as "faulty reasoning".
Linguistic Context
As observed in Ludwig, "slippery slope" functions as a metaphorical noun phrase used to warn of a process that, once started, is difficult to stop. It often acts as the subject or object of a sentence, framing an action as the catalyst for a series of unintended and undesirable events.

Ludwig's WRAP-UP
Ludwig confirms that "slippery slope" is a highly frequent and grammatically correct idiom used across elite media outlets. It serves as a powerful rhetorical device to highlight risks and potential escalations in political, ethical and social arguments. While often associated with logical fallacies, its presence in high-authority publications like The New York Times and The Economist demonstrates its utility in describing complex cause-and-effect relationships. When using it, remember to provide logical steps between the initial action and the predicted outcome to ensure your argument remains robust and persuasive.
