Spot the hallucination

Each answer below mixes true statements with fabricated ones, written in the same confident tone. Tap the claims you would want to check, then see how you did.

Some claims here are deliberately false, and some citations are invented for this exercise. Please do not repeat them.

What to notice

• The fabricated claims sound as sure of themselves as the true ones. Tone tells you nothing.
• Specifics are where invention hides: exact statistics, citations, function names, dates and names.
• Most can be checked in a minute against a real source, or by simply running the code.
