TED-Ed: Why people fall for misinformation | Joseph Isaac

The video explores the misconception of the taste map, which inaccurately divides the tongue into areas for different tastes. Originating from David Hennig's research, the map was misinterpreted and simplified over time, leading to widespread misinformation. The video discusses how such misconceptions arise and persist due to narrative simplicity and human error. It also highlights the complexity of taste, including the recognition of umami as a basic taste, urging viewers to maintain skepticism towards oversimplified scientific claims.

• By being intentionally promoted by scientists.

• Via simplified images and narrative simplicity.
