Industry-Specific Hallucination Patterns in LLMs
Hallucination rates vary dramatically by industry. We tested LLM accuracy across 12 industries and found that healthcare, finance, and deep tech companies experience the highest rates of AI misinformation.
Hallucination rates by industry
- Healthcare/Biotech: 28% hallucination rate (highest — complex terminology).
- Finance/FinTech: 24% (frequently changing metrics).
- Deep Tech/AI: 22% (rapidly evolving landscape).
- E-commerce/Retail: 16% (well-documented online).
- SaaS/Software: 14% (moderate — good web presence).
- Consumer Goods: 11% (lowest — stable, well-known brands).
Why industries differ
- Industries with complex, specialized terminology produce more hallucinations.
- Industries with rapidly changing data (employee counts, funding) see more outdated answers.
- Industries with strong web presence and structured data have lower hallucination rates.
- Recommendation: high-hallucination industries should prioritize structured data publishing.
