Do I Know You?

“Sadie Dingfelder has opened a new window into human neurological diversity, or neurodiversity. She learns about neurodiversity when she discovers she is faceblind. She can see people just fine, but she can’t recognize them. That’s been a problem all her life, and when she is presented with a medical diagnosis—prosopagnosia—she embarks on a voyage of self-discovery that leads her to discover the huge spectrum of human visual processing. The realization that some people see a flat world while others are menaced by three-dimensional objects is stunning. But it doesn’t end there. Digging deeper, she follows psychologists who are unraveling how we think about what we see and how our imaginations and memories are built. It’s a fascinating story that will make you rethink how you see the world.”

“It is rare to find a book that makes you laugh out loud while teaching you a great deal of brain science, but Do I Know You? does just that.  As Sadie Dingfelder explores her own quirky way of experiencing the world, we all discover the many ways we see, remember, and imagine.”

“Discover Sadie Dingfelder’s World That Lacks Visual Memories. It provides great insight to learn that your thought processes may be totally different from how another person's thought processes work.”

“A personal, vulnerable portrait of late-realized neurodivergence, filled with hard-won self-knowledge and plenty of humor.”

“Sadie Dingfelder was born funny, in both senses of the word.”

“When a skilled science writer starts to wonder about her own mental landscape and not that of others, a rare and insightful story unfolds. Dingfelder gives us a front row seat to her subjective reality as understood by modern day psychological and brain sciences. This book is chock full of dazzling insights and told with warmth and humor.”

“What if you discovered that the ‘quirky’ personality your friends know you for is, instead, sign of several unusual neurodevelopmental features? In Do I Know You? Dingfelder deep-dives into her own psychological profile—but what is really on display is her infectious curiosity and enthusiasm. She delivers a tour de force of that most storied scientific approach: experimenting on yourself.” 

“Sadie Dingfelder’s Do I Know You? is an ode to neurodiversity that is as hilarious as it is enlightening. Sadie is an heir to Mary Roach with her talent for making science engaging, strange and deeply funny. What a delight!”

"A hilarious and riveting journey into the fabric of what it means to see, remember, and connect."

“A coming-out story about learning you are part of a community, that you deserve accommodation, that you can practice radical self-love.”

“Funny, poignant, philosophical and almost euphoric. The memoir is a”: beautiful reminder that our inner lives are not uniform. None of us can possibly know what it feels like to be someone else, but as Dingfelder shows, it’s fun to try.”
