Dan Jurafsky is the chair of linguistics and a professor of computer science at Stanford. This video is an incredible, fast-paced presentation he gave at Listen.ai last month.

Dan opened the talk with the history of ketchup and how the language of food can expose historical revisionism. He then moved on to his research on food marketing and potato chips, sharing that every negative word on a potato chip bag add 4 cents to the cost. Dan wrapped it up with a look at the language of menus and speed dating.

Very interesting, learned something new about ketchup!
