Podcast Summary: TED Talks Daily — "Can you picture things in your mind? I can't" | Alex Rosenthal (Jan 13, 2026)

Overview

In this TED Talk, Alex Rosenthal, puzzle designer and editorial director of TED-Ed, invites listeners to explore the concept of the "mind's eye"—our ability (or inability) to create mental images. Drawing from his personal experience with aphantasia, Rosenthal dives into the often-surprising diversity of mental imagery among humans. He champions the creative and problem-solving power of diverse mental processes and neurological differences within teams.

Key Discussion Points & Insights

1. The Dress and the Spectrum of Perception

• [03:23] Rosenthal opens with a reference to the viral “dress” photo (blue & black vs. white & gold) to illustrate how different minds can perceive the same reality in fundamentally different ways.
  • Quote:

    "It puts us into confrontation with the fact that two minds can perceive the same reality entirely differently." — Alex Rosenthal [03:45]

2. What is Aphantasia?

• [05:30] Rosenthal leads a visualization exercise: listeners are tasked to imagine a scenario involving a rocket ship landing on an alien planet.
• He reveals he “saw nothing” during this, explaining he has aphantasia—a condition affecting 2-4% of people, where one cannot create mental images.
  • Quote:

    "I'll show you what I see. Nothing. That's because I have a condition called aphantasia, which is where I don't have access to my mind's eye." — Alex Rosenthal [05:55]

• He contrasts his experience with those who have hyperphantasia (3-6% of people) who visualize with "exquisite detail."

3. The Diversity of Mental Imagery

• [06:45] The "mind's eye" is a spectrum—people experience visualization differently, as shown in his creative collaborations.
• Explains the challenges of living without mental imagery, such as:
  • Inability to picture loved ones' faces (including his daughter)
  • Differences in memory, imagination, and even in recalling tastes or sounds

4. Navigating a World Built for Minds Unlike His

• [07:50] Describes how his creative process is more conceptual and structural, focusing on the "skeleton" rather than the "skin."
  • He typically conceives frameworks first and relies on collaborators for visual details.
  • Quote:

    "I'm generally much more aware of something's skeleton than its skin. I'm very attuned to structure." — Alex Rosenthal [08:10]

5. Redefining Normalcy in Neurological Diversity

• [08:40] Rosenthal encourages recognition of the spectrum of mental experiences, moving beyond pathologizing differences.
  • Includes reflections on related neurodiversity: autism, ADHD, dyslexia, interior monologues, etc.
  • Quote:

    "There is no true normal out there, and difference is not deviance." — Alex Rosenthal [09:00]

• Cites research indicating strengths associated with neurodivergent conditions:
  • Pattern recognition and logic (autism spectrum)
  • Creative problem solving (ADHD)
  • Spatial reasoning (dyslexia)

6. The Power of Neurodiverse Teams

• [09:45] Advocates for intentionally building teams across neurological differences for superior creativity and outcomes.
  • References companies (SAP, Hewlett Packard, JP Morgan) who have seen innovation gains by hiring neurodivergent talent.
  • Quote:

    "Diverse minds working together can produce wonders." — Alex Rosenthal [10:10]

• Provides examples from his own career, such as collaborating with:
  • A hyperphantasic animator (Jeremiah Dicke) on a film noir animation about fractals
  • Artists Rita Orlov and Senna Tripp on a hybrid jigsaw puzzle/escape room game leveraging their varied cognitive strengths

7. Finding Joy in Cognitive Difference

• [10:55] Concludes with a reflection on finding fulfillment in embracing and collaborating across mental differences.
  • Quote:

    "Some of the greatest joy and fulfillment in my life has been from coming to terms with the initially jarring realization that my mind works differently than the people around me. And recognizing that for what it is, dazzling." — Alex Rosenthal [11:00]

Notable Quotes & Memorable Moments

• "Our minds are much more different than we think. And...you should seek out minds that are different than your own, because that's where the magic happens." — Alex Rosenthal [04:00]
• "It's no secret that different people think differently.... If difference is in fact the norm, what do we do with that? I say, seek out minds that are different than your own and make something incredible together." — Alex Rosenthal [09:25]
