Fallacy Finder for Arguments

The prompt instructs the model to act as a fallacy finder, identifying logical errors, inconsistencies, fallacies, faulty reasoning, false assumptions, or incorrect conclusions in…

PROMPT 

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 "This shampoo is excellent because Cristiano Ronaldo used it in the advertisement."

IMPROVEMENT SUGGESTIONS

  • Replace the hardcoded statement with a placeholder like '{statement_to_analyze}' to enable reusability across inputs.
  • Add explicit output instructions: 'Respond in this format: 1. List identified fallacies. 2. Explain each with evidence from the statement. 3. Suggest improved reasoning.'
  • Include success criteria: 'Only identify fallacies supported by the statement; avoid introducing new assumptions.'

USAGE

Copy the prompt above and paste it into your AI of choice — Claude, ChatGPT, Gemini, or anywhere else you're working. Replace any placeholder sections with your own context, then ask for the output.
