Act as a Fallacy Finder

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."

Analysis

The argument in the prompt presents a classic appeal to authority fallacy, as it relies on a celebrity's endorsement rather than substantive evidence regarding the shampoo's quality. While celebrity endorsements can influence consumer perception, they do not provide objective proof of a product's effectiveness or quality. A strength of the argument is its simplicity, making it easily understood, but its weakness lies in the lack of critical evidence.

Improvements

To enhance the prompt, one could emphasize the need for empirical evidence when evaluating product claims. An extended prompt might be: "This shampoo is excellent because Cristiano Ronaldo used it in the advertisement. However, should we also consider user reviews, ingredients, and clinical studies to make a more informed decision?"

Continuing the Conversation

To get better results, the user could ask follow-up questions such as: "What specific evidence should I look for to assess the shampoo's quality?" or "Can you provide examples of more reliable arguments when evaluating products?"
