What does the phrase “you can’t prove a negative” actually mean?
In: 1149
If I asked you to prove you had blown your nose, you could show me a used tissue, video of you blowing your nose, or someone who saw you blow your nose could tell me that you did.
If I asked you to prove you didn’t blow your nose, showing me an empty trash can wouldn’t prove there weren’t used tissues there before, you would need video of every second of your life to show you had never blown it, or someone would need to have seen your nose at all times to prove you hadn’t.
