Hempel Memes

This is a brilliant jab at the contrapositive logical fallacy in science! The title "Proof That All Ravens Are Black" paired with a photo of colorful apples is a perfect illustration of Hempel's Paradox in logic. The paradox states that "All ravens are black" is logically equivalent to "All non-black things are non-ravens." So technically, every green, red, and yellow apple here (being non-black objects that are also non-ravens) actually supports the statement that all ravens are black! It's the kind of twisted logic that makes perfect sense mathematically while being completely ridiculous in practice. Next time someone asks for evidence, just show them something completely unrelated and claim it's proof by contraposition!
