Christina Kim, a reporter and producer on the Throughline team, teams up with Rachel Herz, a neuroscientist and author specializing in the psychology of smell. Together, they explore the profound connection between scent and memory, showing how aromas evoke powerful personal narratives. They share fascinating insights on how smells shape identity and recall, discuss the impact of losing one’s sense of smell during COVID, and highlight historical significance by connecting olfactory experiences to cultural narratives and trauma.
Smell significantly influences personal memories and identity, acting as a powerful emotional connector to past experiences and relationships.
Research on olfaction reveals its profound biological and social implications, highlighting how scents can shape cultural perceptions and enforce social divisions.

The Significance of Smell in Memory and Identity
Smell plays a crucial role in shaping personal memories and connections to identity. A reporter shares how the scent of a family perfume invokes vivid recollections of moments with loved ones, highlighting how aromatic experiences can evoke strong emotional responses. This connection emphasizes the notion that smells can serve as essential bookmarks for significant life events, layering richness into our personal narratives. Ultimately, smell acts as a conduit through which we retrace our history and deepen our sense of self.
Scientific Breakthroughs in the Understanding of Smell
Groundbreaking research on the sense of smell, initiated by scientist Linda Buck, has unveiled the complexities of olfaction. Her discovery of over a thousand smell receptors transformed the understanding of how humans perceive scents, establishing that we can detect around a trillion different odors. This research has significant implications beyond biology; it offers insights into how smell impacts emotions and memories since the brain regions involved in smell processing are closely linked to emotional responses. The progress made in understanding smell underscores its foundational role in human survival and social interaction throughout history.
The Role of Smell in Cultural Perception and Segregation
Smell has been historically intertwined with cultural perceptions, shaping societal attitudes towards inclusion and exclusion. An examination of the Plessy v. Ferguson case reveals that legal arguments regarding racial segregation incorporated perceptions of smell, demonstrating how aromas were used to justify discriminatory practices. This perspective emphasizes that smells can be weaponized, creating divisions based on cultural biases and learned associations. By recognizing these patterns, one can better understand the way sensory experiences have been manipulated throughout history to uphold social hierarchies.
Healing Through the Sense of Smell
Reconnecting with the sense of smell can facilitate emotional healing and cognitive restoration, particularly after loss. Experts suggest techniques like smell training, which involves engaging with familiar scents to reactivate olfactory memories, helping individuals regain their sense of smell after illnesses like COVID-19. Personal accounts illustrate how the revival of scent can restore connections with the past, often tied to ancestry and identity. This process of remembering through smell not only enriches individual experiences but also fosters a sense of continuity across generations.
"History" can seem big and imposing. But it's always intensely personal – it's all of our individual experiences that add up to historical events. Over the next few episodes, we're exploring the personal and how it's changed history: from the story of romantic love, to the man who tried to cure aging, to the contents of our dreams...
First up, memory and our sense of smell. What if we told you that the key to time travel has been right in front of our eyes this whole time? Well, it has: it's in our noses. Today on the show, the science — and politics — of smell, and how it links our past and our present. (Originally ran as The Scent of History)
