DeepSummary
In this episode, Sadie Dingfelder, a freelance science journalist, shares her experience with face blindness or prosopagnosia, a condition that makes it difficult for her to recognize faces of people she knows. She recounts an incident where she mistook a stranger for her husband at a grocery store, which led her to join a clinical study and discover the extent of her face blindness.
Sadie explains that she has two types of face blindness - one that makes it hard for her to tell faces apart and another that impairs her ability to recall rich memories associated with someone's face. She also has aphantasia, which makes it difficult for her to form mental images, and severely deficient autobiographical memory, hindering her ability to remember details about her own life.
Despite feeling mortified initially after learning about her conditions, Sadie eventually realized that these revelations helped explain the mysteries and challenges she had faced throughout her life. She decided to write a book titled 'Do I Know You?' that combines her memoir with the science behind sight, memory, and imagination, aiming to promote understanding and consideration for different ways of experiencing the world.
Key Episodes Takeaways
- Face blindness, or prosopagnosia, is a condition that affects an estimated 10 million Americans, making it difficult for them to recognize faces of people they know.
- People with face blindness may experience difficulties in different aspects, such as distinguishing between faces, recalling memories associated with faces, or forming mental images.
- Sadie Dingfelder, the featured guest, has two types of face blindness, as well as aphantasia (inability to form mental images) and severely deficient autobiographical memory.
- Discovering these conditions helped Sadie make sense of the challenges and mysteries she had faced throughout her life, leading her to write a book exploring the science behind these experiences.
- Sadie's book, 'Do I Know You?', aims to promote understanding and consideration for neurodiversity and different ways of experiencing the world.
- The human brain has a dedicated part called the fusiform face area that is responsible for facial recognition, and this ability is believed to have evolved to facilitate social interactions in early human societies.
- Recognizing faces is a complex process that involves not only perceiving the face as a whole but also associating it with biographical information and memories about the person.
- Sadie's experience highlights the importance of being curious about different perspectives and understanding that people may have qualitatively different experiences of the world due to variations in neurological processing.

- “I did not realize how many flavors of human consciousness there were. I spend a lot of time wondering what it's like to be a cat, for instance.
