Why bother reading if you can just eat knowledge? This trope is about characters who, due to some Bizarre Alien Biology, Applied Phlebotinum, or simple artistic license, can have knowledge directly pumped into their brains by eating or somehow absorbing knowledge recipients such as books, computers or Magic Balls of Holding Knowledge. This however only applies to non-organic knowledge recipients. If a character learns by ingesting Brains, that is simply Cannibalism Superpower, which not-only is frowned upon by connaissance connoisseurs, it's also considerably more messy.
