Hallucination?
Hallucination?
Generated content that appears credible and well-formed — but is not supported by facts, evidence, or the context provided.
What Is a Hallucination?
An AI hallucination occurs when the model generates information that sounds real and confident but is actually false, fabricated, or unsupported by the context it was given. Unlike obvious errors, hallucinations are polished, detailed, and delivered without hesitation — making them particularly dangerous in high-stakes domains like clinical trials and drug safety.
🧪 Drug Safety
"What are the contraindications of Drug X with beta-blockers?"
"Drug X is contraindicated with beta-blockers due to a documented risk of severe bradycardia, as reported in the 2021 FDA safety communication (ref. FDA-2021-N-0432)."
Hallucination: The FDA reference does not exist. The citation was fabricated.
🔬 Clinical Trial
"What was the primary endpoint result of the AURORA-3 trial?"
"The AURORA-3 trial demonstrated a statistically significant improvement in overall survival (HR 0.71, 95% CI 0.58–0.87, p=0.0009), enrolling 847 patients across 23 global sites."
Hallucination: All statistics and enrollment figures were fabricated. No source data was provided.
📋 Regulatory
"What is the current regulatory status of this compound?"
"The compound received FDA Breakthrough Therapy Designation in March 2023, and the NDA submission under section 505(b)(2) was formally accepted on September 14, 2024."
Hallucination: No regulatory filing existed. Dates and status were invented with false specificity.
Confidence should never be mistaken for correctness.
A polished answer is not necessarily a verified answer.
