SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you determine whether an argument’s premises actually support its conclusion, and it flags common logical fallacies that can make a weak case sound convincing.

Core Features & Use Cases

  • Argument structure extraction: Restates premises, conclusion, and the reasoning path before evaluating validity.
  • Premise and inference testing: Assesses whether premises are established/assumed/contested and whether the conclusion follows if the premises are granted.
  • Fallacy detection and verdict: Identifies specific fallacies and produces a clear verdict plus what would strengthen the argument.
  • Use case examples: Reviewing a product decision justification, evaluating a technical proposal’s reasoning chain, or checking an ethics/strategy claim in a document.

Quick Start

Run logic-argument-validation and ask it to validate whether the premises support a stated conclusion, including any fallacies you suspect, for the argument you paste in.

FAQPage Schema
How do I validate an argument's premises and check for logical fallacies?▼

To validate an argument, extract its stated premises and conclusion, assess hidden assumptions, verify inference validity, and identify logical fallacies to produce a structured verdict on whether the conclusion is logically earned.

What is the best way to review a product strategy justification for flawed reasoning?▼

Reviewing a product strategy justification requires testing whether the stated premises actually support the conclusion and flagging common logical fallacies that make a weak case sound convincing.

How does fallacy detection work when evaluating a technical proposal's reasoning chain?▼

Fallacy detection works by restating the reasoning path, assessing whether premises are established or contested, verifying if the conclusion follows, and identifying specific fallacies alongside a clear verdict.

Can I check inference validity for ethics and strategy claims in written documents?▼

Yes, you can check inference validity for ethics and strategy claims by applying argument structure extraction to written reasoning, ensuring the conclusion must be logically earned from its premises.

What should I do when an argument's conclusion does not follow from its premises?▼

When a conclusion does not follow, the validation process outputs a structured verdict identifying specific fallacies and provides feedback on what would be needed to strengthen the argument.
