ResearchFallacy check

Spot logical fallacies in an argument

Use to test whether an argument holds up logically, not just emotionally.

The prompt
prompt.txt
Examine this argument for logical flaws.

The argument:
{{argument}}
Context where I encountered it: {{context}}

Task:
1. Restate the argument's main claim and its supporting reasons.
2. Identify any logical fallacies or reasoning errors, naming each one.
3. Point out unstated assumptions the argument relies on.
4. Note which parts of the argument actually hold up.
5. Suggest what evidence or reasoning would make it stronger.

Constraints: focus on the logic, not whether you agree with the conclusion. Be precise about where each flaw occurs.
