Confidently wrong
Two answers to the same question, both worded with exactly the same confidence — one is true, one is made up. Can you tell which, before you check the source?
What you see
Seven pairs of claims, both worded equally confidently — one is true, one is deliberately made up; the resolution links a hand-checked source.
What it shows
What hallucination feels like from the outside: the confidence of an answer says nothing about whether it is true — sources do.
Like an AI, both answers below sound self-assured. The false ones are built on purpose from typical hallucination patterns — plausible details, precise-sounding claims. None of it is a real AI quote; it is editorially constructed. Every resolution links a source checked by hand.
Can honey go bad?
Honey doesn't spoil. Archaeologists have found pots of honey in ancient Egyptian tombs, thousands of years old and still preserved. The two-year figure is invented.
Can you see the Great Wall of China from the Moon with the naked eye?
No astronaut has ever picked out the Wall with the naked eye, and NASA calls it barely visible even from low orbit. From the Moon it is simply impossible.
Does your browser's Incognito mode make you anonymous online?
Google's own help page says Incognito 'doesn't make you invisible'. It only cleans up locally — your provider, your network and the sites themselves still see you.
Was Napoleon unusually short?
Napoleon was roughly average height for his time, not short. The 'five foot two' came from French inches, which were longer than English ones; British cartoonists did the rest.
Can lightning strike the same place twice?
The US National Weather Service is blunt: lightning often strikes the same place repeatedly. The Empire State Building is hit about 23 times a year.

Are bats blind?
The USGS is clear: bats are not blind. They have small but very sensitive eyes — echolocation is an extra sense in the dark, not a substitute for sight.

Did Einstein fail mathematics at school?
Einstein had top marks in maths and physics and mastered calculus as a teenager. The myth comes from someone mixing up two countries' grading scales.
Confidence is not a signal of truth — sources are.
What this feels like in real operation — an AI delivering a crystal-clear but wrong diagnosis, and the damage of acting on it — is in the article Convincingly wrong.
