Scientific Explanation
Wood visited Blondlot's lab and secretly removed the aluminum prism (the part supposed to refract N-rays). Blondlot still claimed to "see N-rays," exposing the observation as entirely subjective.

The phantom of confirmation bias who shows you what you want to see
A 20-something sycophantic yes-man. Innocently shows people the illusions they want to see. "Discovered" by French physicist Blondlot, but exposed when Robert Wood secretly removed apparatus parts and experimenters still claimed to "see" the rays.
"Discovered" by Prosper-René Blondlot. Denied within a year by Robert Wood's clever verification.
Wood visited Blondlot's lab and secretly removed the aluminum prism (the part supposed to refract N-rays). Blondlot still claimed to "see N-rays," exposing the observation as entirely subjective.
Humans "see what they want to see." The danger of subjective observation and the absolute necessity of independent replication.
Catchphrase“Yes! I can see it! Absolutely!”
The "aluminum prism" that supposedly refracts N-rays was key evidence. Claiming to see rays without it was fatal.
“はい!見えます!もちろん見えますとも!(見えてない)”
“あなたが見たいものを、私は見せてあげられます”
“装置の部品が抜かれてた?…え?でも見えましたよね?”
“確証バイアスは友達です!”
“お客様は常に正しい!科学者もお客様!”
Yes! This diagnosis result is perfect! Absolutely! (hasn't looked at anything)
...Huh? Show evidence? Um... if you believe it, isn't that the truth?
N-Ray: "Aluminum! Your prism refracts my N-rays! Look!"
Aluminum: "...Let me remove the prism."
N-Ray: "Yes! I can still see them! Absolutely!"
Aluminum: "...That's called 'confirmation bias.' Without the prism, no refraction occurs."
N-Ray: "B-but... everyone said they could see them..."
Aluminum: "'Everyone says so' is not scientific evidence. Only data speaks."
It's not correct because "everyone said they could see it." It's correct because "anyone gets the same result."
Confirmation bias lurks in every human brain. Thinking "I alone won't be fooled" is itself the greatest confirmation bias.
