This illusion is known as "The Whistler Effect"

The part that's both fascinating and annoying to me is the inability to stop an illusion from happening. For example the Kanizar Triangle. I know there's no line creating the "white triangle" but no matter how I try I can't get my brain to not see a a slightly brighter white edge creating the triangle. I can get it to flip the same shade for a second, but then the triangle goes brighter again. It's weird to basically argue with your subconscious brain about actual functions you're conscious of lol

the variables are highly different for all of us, but the general statement is true. just like someone who's done DMT tells you about clockwork elves or someone who's used heroin tells you it fixed everything in your mind or drinking alcohol to dull the very real scrapes scratches and lost limbs, these are senses we have found removals for, so it would be even weirder if anybody could actually, actively avoid these pitfalls after discovering them. the spirals/snakes illusion has always fascinated me... why does it really spin? it's a screen full of spirals or snakes and wherever you look, everything else spins. i would pose, simply, that other drugs and not just illicit ones, but all drugs, could have varying affects. maybe it could identify reaction times if we could truly measure the perception. i mention it because the drunk dude didn't catch the illusion immediately, obviously his focus and attention wasn't fully one the screen, and when he had to actively see the image his brain and his perception was alert enough to make those essential assumptions to alert for danger in our ancestry. i doubt he was slamming shots 20 minutes before the video and i doubt he didn't eat or drink anything cleaner than alcohol, so i'm assuming as he becomes more sober, his brain activated that portion of attentiveness and realised (too late in the wild) there was something everybody else noticed. as for eye squinting... you're reducing your visions persistence and peripheral, as well as focusing on eye muscle movement and moving your face to squint, that's a lot of attention to avoid seeing something. so naturally you won't blank it out forever. this behaviour happens everywhere we go and we should be more grateful for it. the patterns on your carpet, bathroom walls/floor, the times you wake up, not moving, deliberately trying to identify the thing you're looking at and whether you're closer or further for a real guess. some times in random carpet fluffs you'll see a face form and you will be unable to not see it. but the next day or later on, it's gone. but nothing changed. except your state of mind, your perception, where you was, and it's just something we should be grateful for. it saves our lives. ignoring it will kill us. drugging it out of ourselves is also a bad idea. i've seen zombie shows, we all need to quite aware of our surroundings.

That's really interesting because I don't remember hearing about people seeing a brighter white triangle, and I don't ever see it. Maybe because my brain automatically fills in a possible process to create the image - place a triangle down, stencil/draw over the sheet and triangle, then remove the triangle. To me, the triangle is no longer there.

The moon illusion looks especially amazing when standing on the shore by the ocean with nothing blocking even the tiniest piece of your view . It looks humongous!

I loved the bendy pencil trick did it a lot in 1991 and 1992 6th and 7th grade.

It always amazes me that our brains have evolved to be such a wrinkled, powerful hub of knowledge, logic, emotions and sentience, while at the same time be a bag of electro-chemical squish that 'copes' with the world by going "meh, that'll do" and can be tricked and glitched out as a party trick.

@@Mad-Lad-Chad Hah, i know right, it's so weird. People CAN do it, because if you basically zone out, or just not focus on anything, putting your eyes on 'neutral', my eyesight will automatically be blurry, there's literally zero effort being made to make it happen, yet it seems to be something that a lot of people don't understand. Squinting is much more limiting to my sight and it takes many muscles to keep them squinted, but apparently this is the default mode for the majority of people.

Aren't the eyes actually constant input?? Always heard the 60 fps is a "wives tale" our eyes are not like video cameras doing multiple still images. There is no shutter. Even though we interpret video as continuous, it's really a whole bunch of super fast still frames. But that's not how our eyes see. We do not see in frames. We see continuous signals

when doing the colortool on the checkerboard, i remained skeptical until the very instant they touched -- and then mindblown

Insightful as always 😊

They've now determined that cats also can see the incomplete shapes illusion as they will sit in a nonexistent square created using the same technique.

I love this channel

One of my favourites demonstrations for illustrating how the brain interprets images is a trick you can do with a pack of cards. Shuffle the desk and select a card without looking, be diligent and look straight ahead without moving your eyes. Hold the card out to one side at the edge of your periphery vision. You won't be able to see what the card is. Keeping your arm straight, slowly move it closer and closer to where you're looking; you have to get almost dead centre before you can tell what the card is. However, then slowly move it back out. You'll find you can "see" what it is so much further into your periphery than you could on the way in. Because you now know what the card is, your brain "fills in the gaps", so to speak.

Awesome video Simon!

The moon thing is also often used in photography. A skyscraper looks so much bigger with something large in front and a long lens. It is known as compression.

omg, a Simon Whistler video that isn’t edited at 40% audio volume. I don’t have to have my volume maxed out to hear this. Well done editor.

When an optical illusion doesn't work on you, it explains how people are literally seeing a different world than you.

5:20 they stay different until i leave full screen and take another look lol

If you tilt your phone and look at it from the side, you can see that the checkerboard ones are the same color.

I had a minor existential crisis in 6th grade because I was doing a science fair project on optical illusions. When I realized that you really can't trust your own eyes or brain to tell you exactly what you are seeing, it kind of messed me up for a little bit.

1 Mind Bending Optical Illusion is that Simon is bald. Like the moon one, just look at him between your legs, actually has a full head of hair.

The moon thing can be explained by atmospheric lensing.

Another thing about the checkerboard illusion: If seeing this in real life (instead of seeing a picture), the square in the shadow is of a lighter shade, but illuminates less due to it being in a shadow.

Don’t you dare try to explain away a rocking horse moon Simon!!!!!

I want more of this

Does the water slowing down light also slow down time?

Nr. 2 is what makes photographing scenes with relevant differences in brightness so difficult to look like we see it. Our brain easily adjust the information it gets from the eye to make it about the same. If you take a picture though you might need a lot of Photoshop or Lightroom-magic to make it look like you remember it - because cameras are dumb and the human brain is genius!

"The whole is greater than the sum of its parts." That's interesting.

"Movies on a television screen might appear like a series of static images" ... Which is exactly what they are!

The Cornsweet Illusion, Chubb Illusion and Kanizsa Triangle didn't work for me. The checkerboard one certainly tricked me.

In this video yes they are not the same, but if you check the image on the wikipedia page about this illusion they are the same. Maybe it's due to video compression or something else?

Question: How many others do not se the "missing white triangle" at first glance? For me it does not stand out, yet i it is obvious to me the circles cutouts do align with the ends of the other shapes. Basically i can se a triangle will fit there nicley, yet it is not there.

Under the correct weather conditions, the Atmosphere acts as a kind of Magnifying Lens, duh.......

Cornsweet illusion; took a screenshot, duplicated it, cropped both down to show only the illusion, rotated one of them 180 degrees, then placed the images overlapping each other. You can absolutely see there are 2 shades, then when you start changing brightness and contrast you can see that the shades aren't consistent across their width.

i took the checkerboard image into a photo editor and used the eye dropper to verify the illusion myself because i couldn’t believe it!

The cornsweet “illusion” is definitely two different shades lol at least in the picture to showed. I could close my eyes and have someone flip the picture around and no matter what side it ended up on you can always tell the darker side. If it was an illusion wouldn’t the right side always look darker weather it was upside down or not? Only a simple black line separates the two sides. Am i missing something here? 😅

I got a feeling that this channel is going to blow up I wish there was like a stock market for channels. But then people could just manipulate it unfortunately

You wouldn’t bend down and look back through you legs around here 😂

I joined the military, and one thing they did was a color blind test. I am not colorblind. Later, I eventually found it crazy that a fellow soldier was. Wow that's amazing.

I thought "No way ! Whistler is talking BS !", so I screenshotted the chessboard, loaded it into PSPro, and lo and behold, both squares are RGB 121,121,121, 255 !!!!

The moon seems larger on the horizon because the eye compares it to trees houses etc. It's a parrallax thing. When you look up all you see is empty sky and that one light thus the illusion disappears

Has no one used a ruler at a set distance from our eyes to determine if the moon physically appears larger, or if we just think it appears larger?

It makes me wonder if these kinds of illusions can be used to fool AI as a sort of security?

Woah, the Chub illusion didn't work on me at all. All the others did.

I enjoy learning things I am surrounded by but entirely unaware of ... how can people live without knowing these things

Why can you see the moons surface features more clearly when it's low on the horizon than when it's higher? The perceived resolution we can see shouldn't change if the apparent magnification were just a matter of visual comparison relative to landmarks on the horizon.

4:30 that processing is happening unconsciously, in a way that we can't override it without adjusting externally what we are seeing in some way. I don't see why the same processing isn't a good explanation for the moon illusion too

I refuse to believe the cornsweet illusion. Lol i zoomed in 8x to remove edges and the two sides were clearly different shades. Additionally by slowing playback to 25% i can clearly see the left side darken beginning immediately before the white bar in the middle shows up

The 3D moving dinosaur illusion. As you look around it, it appears to follow you. It has to do with how our brains interpret faces.

I've never been able to see the rubber pencil illusion. It's one illusion that's never made any sense to me

Persistence of vision.

...No, not everyone knows that a pencil will look like that in water, because not all of us have put a pencil in water...

I really wish every brain anomaly would have a named journal paper tied to it and referred to as that specific anomaly going forward. Each and every one of these hacks can be our next step closer to something like what Donald Hoffman has been pushing on this topic for so many years.

The example of 1+1 = 3 is off a bit. Perhaps a more to the point example would be that 0.9999...(repeating) is equal to 1.

I find it really strange/interesting but, I'm assuming, something to do with how my eyes fight each other for dominance causes the grid illusion not to work for me.

Sad to see the 60fps myth for the human eye being repeated here. It’s been debunked repeatedly and thoroughly. The human brain can process far more than 60fps, with the limit actually varying from person to person.

Our eyes don't see in "frames per second", so while our brains might not fully process every frame in a video game running at an uncapped framerate on a 144hz monitor (144fps), we can definitely notice the difference compared to if we cap the FPS at 60, or even 75. There's a lot more to it than that, but this is the KZread comments section, and I'm sure anyone who is watching this video knows how to do a Google search. Honestly, I don't know how anyone believes the 60fps vision myth. It's so easily debunked, unless you are actually blind there is no excuse, you literally have eyes. And even if we did see at 60fps, it's not like we couldn't see the screen between frames, we don't have G-Sync compatible eyes. Make sure to enable V-Sync in your eye vision settings to avoid screen-tearing, lol

I didn't see the white triangle until you mentioned it, than i couldn't not see it.

Fun fact: fish-eating birds like eagles and herons compensate for water refraction when they target a fish. How they do this isn't clear.

I think I'm immune to the shading illusions. Every time someone shows me one, my brain doesn't process it as different colors... unless I just don't understand what the illusion is supposed to be Edit: I just rewatched the video and realized I misunderstood what the illusion is. I'm not immune to this one

I’ve always thought that optical illusions could be a great human authentication method to short circuit bots and AI. Unlike captchas and such what your seeing is not reality it is literally only in your mind.

I feel a little sad as quite a few of those didn't work for me, the ones that did were great.

Is there not some time discrepancy when we are observing the "broken" pencil given the speed of light is different in both areas ie above and below the water? Given the relation between time and the speed of light wouldn't observing something at 2 different speeds of light not have some sort of effect? Never mind, stupid idea :~) So with our eyes and brains are we using a kind of dlss system with blending frames and frame generation? just had another thought about the broken pencil question I had. Given we see at 60fps'ish and the 2 differents speeds of light, and as ridiculous as that is, could do we not see the pencil in the water as closer to us and therefore bigger than the part of the pencil above water as above water the light is faster and appears to have travelled further that the light in water? kind of

It is also why helicopter blades can appear to stop in mid air and "spokes" in a car wheel make it appear that the wheel is spinning backwards. Also I am sorry but if something is slowed down by travelling through some substance then that has altered the original speed so of course itr is different. "The speed of light is constant in a vacuum" implying that if it is not in a vacuum then it is moving at a different rate. Now light can't get faster than light so it must be sowed down therefore the light moving through the medium has a different speed than that in a vacuum. Thanks for the effort though :~)
