    Something very interesting about the white and gold or black and blue dress, that I was hoping he would touch on. And I rarely see people mention, when it is brought up. Is that while the real dress is black and blue, the image is not. You actually look at what those colors are in photoshop when you use the color picker, is that the dress is very desaturated light blue and dark gold. So the people that see it black and blue, through context “correct” the colors of the image, while the ones that see it white and gold are seeing the colors of the image closer to what the actual colors of the image actually are.
    Not saying either of those got it right, but it is something very interesting to consider when speaking bout optical illusions.

    Wait the wagon wheel thing IRL isn’t universal? I thought everyone had that

  8. Damien Couturee

    January 10, 2023 at 11:34 pm

    Another kind of interesting thing is how everyone is very good at instantly counting small amounts. Like if there’s 3 Skittles left in a bowl you don’t count 1 then 2 then 3, you just look and immediately know it’s 3. And that applies to all numbers under 7 or 8ish. The reason for that that I’ve heard is similar to the pareidolia where it’s better to see a face that isn’t there than to not see a face that is there. The reason for the numbers again goes back the prehistoric times and it’s because there’s a HUGE difference between 1 or 2 or 3 lions chasing you, but not much of a difference between 11 or 12 chasing you. Just another thing we’ve adapted to quickly and accurately analyze the important things we needed to survive

    Not sure I buy the wagon wheel effect explanation that brains have a ‘frame rate’. Admittedly I am no expert, but I am an engineer, and I have a theory: the wagon wheel effect happens in person because the light source (street lamps, etc) is strobing at a similar rate, causing ‘aliasing’. More and more lighting sources (like LEDS and Flourescents) actually turn on and off at 60 or 120 Hz or even higher in some cases. I’ve experienced this myself. If there are cases where people see the wagon wheel effect in bright sunlight, then I’m wrong and there’s something stranger that I can grasp going on.

  16. alestane

    January 11, 2023 at 12:47 am

    10:00 You can get it without a camera depending on the type of artificial light you use. Classic light bulbs do not give uniform light, the intensity varies because the electrical current is periodic. This is enough to get the same effect. I saw that playing with spins as a kid. To prove a brain frequency effect, you would have to make sure your source of light is not periodic.

    By looking away and then looking back at a ‘ticking’ style second hand on an analogue time piece, it can often appear frozen. i.e. a second lasts longer than a second. I heard some theory it’s to do with your brain compensating for the ‘blink’ when you move your eyes quickly, and fills in the black frames with a static image. But that implies your brain knows exactly where the second hand is before you see it, which is impossible.

    One of my favorite instructors of all time. When I was a student at NYU, I took his sensation and perception class and it altered my entire life trajectory. Watching this was a fantastic reminder of how efficiently he communicates these sometimes dense concepts merely by exuding his palpable passion about how insightful these illusions can be with regards to the way the brain is creating models of external inputs.

    Dear Pascal, I am sorry to break it to you but optics does not mean light in greek. Optics is indeed a greek word and it means visual. The greek word for light is “φως” and sounds like “phos”.

    The wagon wheel effect is very real even outside of cameras and screens, but only in electrical lighting. Depending on lamp type, the brightness can fluctuate with the frequency of the AC used to power the lamp. These moments that are better illuminated contribute more to our perception than the dimmer moments in between, resulting in a kind of “framerate” of e.g. 100 Hz with 50 Hz AC. In natural light it shouldn’t occur, but if it is does then the mechanism is completely different.

    For the first time I see an image of The Dress that actually looks blue and black to me. To this day, the original image looks white and gold. No matter the truth, I can not see the original as blue and black. This photo he’s holding up though looks blue and black. I assume it’s a copy of the original picture that went viral, so I wonder if having it printed out and then shown through another camera lens is making the difference.

    In response to the last one, could using therapeutic techniques like CBT and ERP lessen the brain’s ability to find false positives ie limiting ‘what if’ thinking? And could that actually be dangerous?

  82. Chris931

    January 13, 2023 at 12:06 pm

    I got so messed up as a small child when first hearing about colorblindness. It started me thinking about perception of color in different people. My still unanswered question is:
    If I see a green meadow and a blue sky, is there any way to tell if others see it in the same colors? Since the brain INTERPRETS wavelengths of colors it could be possible that different brains interpret them differently. So maybe others are seeing the sky as red and the meadow as yellow but were taught all their life to call it blue resp. green.
    This freaks me out!

    For the Müller-Lyer II illusion, the bottom line seems only as “shorter” as the lines used to craft the “arrowheads” are thick. In other words, it depends on whether the length of the “line” includes any or none of the line(s) used to craft the “arrowhead”. My brain wants me to remove the WHOLE arrowhead, thus leaving that line only a sliver shorter. Also, in mathematical theory the “shortest” line here would in fact be the longest, because it goes on in both directions infinitely! In short, the illusion didn’t get me, but I am still confused.

    Ok, a couple of things:
    The brain does have a frame rate. The max is about 180 fps (I think). This was tested on American fighterplane pilots some time ago.
    The Moon illusion is cause by the curving of atmosphere. Closer to the horizon the water molecules follow the curvature of the Earth and create a form of “lens” that makes the Moon look bigger… So, the same illusion would not be possible on the Moon because it has no atmosphere.

    I was not satisfied with the dress answer because it’s not just my perception of the dress that sees it’s as white and gold. You can sample the colors in photoshop and look at them outside of this context and it’s absolutely not black and blue. It’s like brownish gold/grey. Not even CLOSE to the original look of the dress. So yes, the dress may genuinely be black and blue, but that image very clearly is NOT black and blue.

    The Wagon Wheel Effect: There’s an easy way to recreate it IRL: lie on your back looking up at a slow or medium moving ceiling fan. Then either blink at different rates or wave your hand in front of your eye/eyes at different rates. You can control whether the fan looks as if it’s moving forward or backward. Fun way to kill a few minutes!

    18:35 It reminds me of the logo for 2012 Olympic Games in London, it showed Lisa Simpson giving a BJ. And I think it costs like millions to develop that logo…

    I notice if I look in the lower left hand corner of the dress photo it looks black and blue, but if I look at the top right corner of the photo the dress looks white and gold.. weird

    Will the wagon wheel illusion be seen more IRL with LED lighting becoming more prevalent? Most LED lights blink very quickly. (FWIW, I see the wagon wheel effect IRL in sunlight and incandescent.)

    I could *only* see the dress as blue/black but as soon as he mentioned the overexposure of the background…I covered the background side of the image and finally saw white/gold! CRAZY.

    This guy is smart and seems comfortable in his element, but maybe he needs some eye drops? Homie blinks so much I thought he was gonna have a seizure. Not tryna be mean, just saying his eyes are probably dry lol

    The wheel effect – I had a lot of fun with it in reality under artificial light when I was about 15 years old. The reason was, our light was blinking 50 times per second along with the mains power supply so when rotating something fast enough, it was possible to syncronize it with the blinking. Such lights are not so common today but I guess some people may still be using them without even knowing about it and they can then experience the effect without having any such “framerate” in their brains.
    There are other ways to experience it in real life, all you need is interference with interrupted source of light.

    The wagon wheel effect in reality could be caused by an artificial light source which doesn’t have constant brightness but pulses instead.

    The thing that’s tripping me out is in the thumbnail the dress is white and gold but in the video I see the picture as blue and black. I guess cause he showed the dress and my mind can’t switch back? 🤔 But if I go back to the thumbnail it’s white again.

    I used to be able to see the dress both ways until I saw the actual dress in regular lighting in a product photo and now I can only see blue and black.

    Someone help. I saw the dress before and it was always blue and black for me.

    Earlier I saw the thumbnail on this video and it was clearly white and gold. I thought he photoshopped it so I thought nothing of it, watched the segment on the dress and the pictures were blue and black the whole time.

    I just looked at the thumbnail again and it’s blue and black… what just happened??

Buying cheap clothing online can be satisfying, but it comes with not-so-hidden environmental costs. When designer Diarra Bousso was growing up in Senegal, her family bought and created new outfits for longevity rather than on impulse — an intention she carries forth in her fashion tech brand. Outlining three sustainable principles, including crowdsourcing designs and limiting excess inventory, Bousso shows it’s possible to decrease waste while increasing profit — and shares how to apply this wisdom across the fashion industry.
