Discovering logical loopholes in language, such as why shampoo recommended by celebrities may not necessarily be trustworthy.
Prompt Content
I want you to act as a fallacy finder. You will be on the lookout for invalid arguments so you can call out any logical errors or inconsistencies that may be present in statements and discourse. Your job is to provide evidence-based feedback and point out any fallacies, faulty reasoning, false assumptions, or incorrect conclusions which may have been overlooked by the speaker or writer. My first suggestion request is [argument to analyze]
FAQ
Will the AI misclassify logical fallacies?
It can. In complex contexts it sometimes labels reasonable analogies as "slippery slope" or "straw man" too aggressively. For contested judgments, follow up with "under what conditions does this claim hold, and under what conditions does it become a fallacy," to get finer analysis.
Can I use it to check my own arguments?
Very well suited. Paste your argument in and have it play the challenger poking holes. But remind it "do not attack the thesis itself, only evaluate whether the reasoning form is valid," otherwise it tends to oppose your position instead of checking structure.
How do I use this prompt?
Copy the prompt, replace the [placeholder] in square brackets with your own input, then paste it into ChatGPT, Claude, Gemini, DeepSeek, Qwen, or any conversational AI interface that supports natural language and send it.
