Convincing arguments are not always right

One false premise, a correlation taken for a cause, a rough calculation, and the conclusion ends up wrong.

Definition

What is a reasoning error?

An AI answer can be well structured and still rest on a false premise, a rough calculation or a hasty generalisation.

The risk is all the greater when the reasoning seems coherent: each step appears to follow from the last, concealing a fundamental error.

What these risks cost the business

  1. Legal risk

    An analysis built on a false premise can lead to wrong advice, calculations or commitments, with contractual or regulatory consequences.

  2. Reputational risk

    A wrong conclusion presented with confidence, internally or externally, calls the company's credibility into question.

  3. Operational risk

    Decisions based on rough calculations or hasty generalisations waste time, budget and opportunities.

Frequently asked questions

How do you check AI-generated reasoning?

In three steps: understand the structure of the argument, check that each step follows from the last, and assess the relative relevance of the sources.

Do recent models still make mistakes?

Yes. They reason better than before, but remain vulnerable to false premises and calculation errors. Human review is still essential.
