Songs stick in our heads for all sorts of reasons, but new research finds that listeners love tunes more when one particular word is included in the lyrics. A new study by Wharton marketing professor Jonah Berger and Grant Packard, marketing professor at York University’s Schulich School of Business, zeroes in on the humble pronoun “you.” Berger joined us to talk about his paper with Packard, which is titled “Thinking of You: How Second-person Pronouns Shape Cultural Success.” (Listen to the podcast at the top of this page.) The study is part of a larger look at how precise language affects consumer behavior, with implications for marketing, sales and customer service.
