The Curse of Knowledge Is Killing Your Message, ep44 Hardcore and At Ease #messagingtips

In this video, Shelly Rood discusses the cognitive bias known as the curse of knowledge, which hampers experts from seeing their work from a novice’s perspective. She explains that the bias isn’t a discipline or preparation issue but a mental shortcut identified by economists Camerer, Loewenstein, and Weber in a 1989 Journal of Political Economy paper. Rood highlights how expertise rewires perception, making it impossible to “unsee” what one already knows. She brings the concept into the communication realm by referencing Chip and Dan Heath’s popularization of the bias in Made to Stick, describing a classic study where participants tapped the rhythm of a familiar song on a table while a partner tried to guess the song, illustrating how experts assume shared knowledge that novices lack.
