When AI fabricates information: reputation risks you need to be aware of
AI does not fact-check; it predicts fluent wording, and sometimes guesses completely wrong with great confidence.
Language AI can fabricate data, quotes, and historical milestones that sound very convincing but are completely false; this characteristic is called hallucination. Since the model prioritizes fluency over factual accuracy, it will not say 'I am not sure,' but will fabricate answers with certainty. For a brand, a single incorrect number that gets out is a brand error, not a tool error.
- purely creative content does not assert facts
- internal rough draft without data
- ideas and text variations have low risk
- public or legal statements
- content with specific numbers and sources
- claims asserting unverified facts
Hallucination is not a rare occurrence with AI. This is a characteristic of how language models operate: they predict the next sequence of words that sounds most reasonable, not fact-checking. When there is no correct data to predict from, the model still provides an answer, and that answer sounds very confident. The brand's issue is not whether AI is wrong or not, but who is responsible if that error reaches the customer.
Why AI doesn't know it's wrong
Research in the journal Nature indicates that the current model scoring rewards the generation of fluent sentences rather than acknowledging uncertainty. This means that when there is no correct answer in the data, the model fabricates one instead of saying "I don't know." The result: you receive a confident, coherent output, but it may be entirely untrue.
Cannot infer any specific actions from an increase or decrease in numbers.
The content area is the easiest to fabricate
Not all types of content carry the same level of risk. You need to know where the danger zones are to focus your verification.
- Numbers and statistics: ratios, percentages, market size. AI often fabricates these numbers with false accuracy, for example, "73% of consumers believe that...".
- Citing and sourcing: organization name, research name, author name. AI can attribute a fabricated statement to a real organization.
- Milestones and specific events: dates, names, context of a product or policy's inception.
- Legal and regulatory information: laws, decrees, industry standards. Errors here have legal consequences, not just reputational.
Purely creative content, such as campaign idea proposals or variations of taglines, does not assert facts, thus carries lower risk. However, even then, it is essential to review the tone to ensure it aligns with the brand.
The risk to reputation increases with public exposure
Internal reference documents: Lower risk due to limited scope, but should still be marked "needs verification" so readers do not inadvertently use unverified data.
External content, public statements, customer documents: Must have someone responsible for verification before posting or sending. AI only assists in the draft stage, with a human signing off at the end.
The FTC (Federal Trade Commission of the United States) guide for 2025 on advertising using AI clearly states: AI-generated content must be truthful and substantiated just like content written by humans. Using AI does not absolve legal or ethical responsibility for false or misleading statements. This principle applies regardless of the tools you use.
Common errors in practice
- If the AI-generated number sounds reasonable, just use it without checking the source.
- Copying the exact AI output into documents sent to clients for assured writing style.
- Confusing AI's confident tone with accurate information.
- No official verification step in the process, so AI errors become brand communication errors.
- Assign AI-generated statements to the name of a real reputable organization, creating fake citations.
The viewpoint of Sinh Vũ
Better to be qualitative than to fabricate. Anything without a source should not be claimed.
Principles of Sinh Vũ Studio practice
Sinh Vũ uses AI to draft, shortening the startup time and exploring different wording directions. However, all numbers, claims, and sources in documents sent to clients are reviewed by a person before going out. This is not due to distrust in the tool, but because the reputation built over years cannot be traded for speed at the final stage.
For you, the practical question is not "Can AI fabricate?" but rather "In your process, is that fabrication stopped before it goes out?" If you do not have a clear answer, that is a point that needs to be addressed before expanding the use of AI for external content.

Frequently asked questions
I use AI to write content faster, so do I have to verify each sentence? That seems too much work.
Not every sentence, but by type of content. Purely creative parts like ideas and variations have lower risks. Parts that contain factual elements, including numbers, sources, commitments, and organizational quotes, must be verified by someone before publication. Focus on checking points that could cause harm if incorrect; there's no need to spread the checks evenly across everything.
AI provides a number, I search Google and find similar results, can I trust it?
Not enough. The frustrations of business owners and the needs of customers are often two different matters. The right question is: is the old name hindering customers in any way? If not, changing the name primarily serves the owner's emotions, not market needs.
