Rocky Road: Why It Sounds So Dang Delicious

Rocky Road: Why It Sounds So Dang Delicious

Author: Science Friday and WNYC Studios August 5, 2020 Duration: 17:56
Rocky Road is just a good name for an ice cream flavor. So good, in fact, that two ice cream institutions have dueling claims to Rocky Road’s invention. It’s a story of alleged confessions and a whole lot of ice cream-fueled drama. If it were just the flavor that made Rocky Road so special, every company could have just made their own concoction of nuts, chocolate, and marshmallows, named it “Muddy Street” or “Pebble Lane,” and called it a day. But there’s a linguistic reason why Rocky Road just sounds so dang delicious—and it’s studied by linguists and marketers alike. Fenton's Creamery in Oakland, California, one of the institutions that lays claim to inventing Rocky Road. (Wikimedia Commons)     In this episode, we mention the Bouba Kiki Effect. Imagine two shapes: One is a pointy, jagged polygon, the other an ameboid-like splotch. Which shape would you name “Bouba,” and which would you name “Kiki?” In study after study, 90% of people agree—the pointy shape is “Kiki” and the rounded shape is “Bouba.” This so-called “Bouba-Kiki Effect” holds in many languages, and has even been demonstrated with toddlers. But why the near-universal agreement? Cognitive psychologists like Kelly McCormick have several theories.

Every word has a past, a hidden history etched into its syllables that often points to a larger discovery or a forgotten moment in time. Science Diction digs into that etymology, uncovering how the language we use to describe the world is itself a product of observation, error, and cultural shift. This isn't just a dry glossary; each episode is a narrative detective story that starts with a single term. You’ll hear how "meme" was coined from a specific concept in evolutionary biology, long before it described internet jokes, or why a global pandemic was mislabeled the "Spanish flu," revealing stories of geopolitics and information control. The podcast, from Science Friday and WNYC Studios, explores the intersection of science, culture, and history by looking at the very words we use to frame our understanding. It’s for the curious listener who enjoys peeling back the layers of common parlance to find the precise experiments, the bold personalities, and the accidental coinages that shaped our vocabulary. Tune in to hear how scientific terminology is never just technical jargon-it’s a living record of human inquiry, full of twists, debates, and occasional blunders that have permanently entered our lexicon.
