When Blindsight is 20/20

We tend to think of physical blindness like a blindfold, but it’s much more complicated than that, and in some instances, people who have lost their vision can still "see" subconsciously.

    Consciousness is such a weird and complicated thing everybody takes for granted.
  • @smooth3333
    The biggest surprise is that we had to go this long into the current year to find a 20/20 pun.
  • @SolarScion
    Blindsight is also the title (and core concept) behind a hard science fiction first contact novel by Peter Watts. Very imaginative, kind of frightening, and some exceedingly neuroatypical characters. Highly recommended.
  • @user-vn7ce5ig1z
    People with cortical-blindness can also catch stuff thrown to them… but don't go throwing stuff at blind people.
  • @Cloudtail33
    Who needs Darkvision when you can get Blindsight?
  • @Jane-yg3vz
    I had a weird episode when I was three where I thought I was blind for a few minutes and started to freak out. I stumbled downstairs with my hands out feeling my way and stumbled over shoes by the front door. I was screaming and crying that I couldn't see but I could. I just thought and acted like I couldn't and it was really scary. I have no idea why this happened but this video reminds me of that.
  • @spindash64
    Now I’m remembering when Spongebob could only drive while blindfolded
  • @NotHPotter
    Well, that was an unsettling statement to end on. Thanks Britt!
  • @TheLunaLockhart
    well. I didn't need THAT question on my mind at the end there lol
  • @BrainsApplied
    This reminds me of that guy who could clearly see, but his brain wasn't able to connect the lines to separate objects or humans. He just learned to recognize line patterns by heart.
  • @laffy7204
    2:17 TN didn't have blindsight, the patient just has ultra instinct
  • @nr18media
    0:32, I completely misheard when you said “rhesus monkey” - I thought you said “racist monkey” so I was wondering how on earth they found out it was racist 😂
  • @savannah4439
    So if a person with blindsight sees something scary, like say a threatening dog, would they feel fear without knowing why they’re afraid? Because their amygdala is getting that fear signal?
  • This made me think of the way Molly Burke responds to visual cues so well during conversation despite not being able to "see" them.
  • 5:31 I think there's a previous draft of the scipt lefto-over in the subtitles or something XD
  • @AveryMilieu
    Off the wall, but a genuine experience... I can "see" (occasionally) when my eyes are closed. Not clear vision, more shadowy,. Dark on dark, really. But I've been able to lay my hands on things in the dark or with my eyes closed for years... But not when I'm blindfolded. So it would seem I'm seeing through my eyelids? I often wondered...
  • @danieltdp
    Many times, when something falls on my peripheral vision, I grab it way before consciously knowing what is happening.
