Why AI hallucinates
Training cutoff
Knowledge has a date limit. Anything after is guesswork.
Pattern completion
AI predicts the most likely next word, not the most accurate.
"The CEO said..."
No source of truth
Generates from patterns, not from a database of verified facts.
The trust spectrum
Your fact-checking toolkit
Use Perplexity for facts
It cites sources. If a claim has no citation, be skeptical.
Cross-reference numbers
Any statistic, revenue figure, or date — verify with a quick search.
Ask "Are you sure?"
AI will often correct itself when challenged. If it doubles down, still verify.
