Moving Illusions


Hey, Vsauce. Michael here. This is a completely still image but as your eye reads well I’m
saying and jumps from word to word, the paragraph will appear to slightly, just subtly, wave and boil. The allusion is called anomalous motion. It’s neat. But to say it’s fun is tautology because the word illusion literally means to have fun, to mock, to play with. But illusions aren’t just fun and games. They also teach us about our brains. Anomalous motion, for instance, demonstrates that our brains process things at different rates and piece by piece. After a saccade, a quick eye movement, higher contrast elements are perceived sooner than lower contrast ones. When arranged in just the right way,
this delay is exploited and your visual system only has one explanation. Low contrast parts of the image
didn’t get processed later because this myelinated machine is
wrong but rather because the image itself must be moving. Akiyoshi Kitaoka’s brilliant “Out of focus” causes nearby neurones to
disagree about the little slices they each detect. Some see big changes after a saccade and some see hardly any.
This makes it difficult for our brains to calculate and factor in the effect of our own eye movements, so the image itself appears to be moving. But illusions aren’t just about moving. They can also be moving, poignant, significant, practical. They can mean the difference
between life and death, like in nature or during World War I as dazzle paint on ships.
This form of camouflage doesn’t conceal the object but rather makes it difficult for an enemy to ascertain its prey’s true shape and thus where it’s heading or how fast it’s going. In 1955 the Soviet Union displayed their new
Bison and Bear long-range bombers at an air show. It looked like they had a lot. Afraid of falling behind, the US
ramped up production on their own B-52 bomber. But the whole thing was an illusion. In the Soviet’s film of the air show the same few planes had been flown
past the camera multiple times in formations that gave the illusion of
them having more bombers than they really did. By the end of the
1950s the Soviet Union only had about 150 long-range bombers, whereas the Americans, fooled by the illusion, had built nearly 2,000 at a cost of 900 million dollars. Architecture is full of examples of real-world practical optical illusions. My favorite are Disney castles. They appear huge but it’s forced perspective – a lie. The tops appear further away from us because they are actually quite tiny. Illusions also tell us about ourselves culturally. The Müller-Lyer illusion is classic. The horizontal lines are all the same
length but the bottom ones appear longer to people from Western cultures, familiar with our rules of perspective
and man-made straight lines. However, bushmen from
Southern Africa and tribespeople from northern Angola or the Ivory Coast aren’t fooled at all. Akiyoshi Kitaoka is using optical illusions to discover glaucoma earlier than current techniques can. And anamorphic illusions are used to save lives. They look weird from any perspective but one,
from which they seem to pop out defying the environment’s actual shape. Hoping to remind drivers to always pay attention traffic safety organizations in
West Vancouver, Canada placed a skewed decal on the road. From the right perspective, the perspective of the driver in this case,
it becomes a 3D illusion of a child you are about to hit. Slow down. Brusspub has made some
incredible examples of the 3D effect such illusions can happen. This object? Just an anamorphic projection. Anamorphic illusions have also
been used to safely practice political dissent. In 1746 supporters of the Stuart claim to the British throne had to be quiet about it. It was treasonous. So, sympathizers served things on trays that looked like this. Innocuous enough until only supporters were around.
And it was safe for someone to place a reflective goblet or cylinder on the tray,
revealing the tray’s anamorphic secret a hidden portrait of their elicit love, Charles Edward Stuart himself. The Encyclopedia Titanica lists descriptions of everybody recovered from the Titanic. It’s quite macabre. Why was the iceberg not seen until it was too late? And why did the nearest ship – the Californian – not come to the Titanic’s rescue sooner? Tragic questions whose answers might be optical illusions. The Titanic was sailing through conditions perfect for mirages. This theory points out that the Titanic sank at the border of the warmer Gulf Stream
and the frigid Labrador Current, where the normal case of cooler air at higher altitudes was inverted – a thermal inversion. Now, because the temperature of air
effects its index of refraction, a thermal inversion means light bending in a typical ways. If light reaches the eye from higher up than usual, objects can appear to float. Seriously. Like this ship off the coast of Australia. A thermal inversion can also render
objects completely unrecognizable, hidden within a haze, like this ship(?) Or like an iceberg. Or a sinking ship in need of help. The Delboeuf illusion may be causing teeth to split and crack more often than they should when dentists drill holes in them. Doctor Robert O’Shea observed 8 practicing dentists and found that
they were all drilling holes that were too big,
even though they knew the correct size to be drilling. Why? Well, it may be the same reason people eat more food when they’re given a bigger plate. Objects appear smaller when enclosed by larger areas. Holes of the same size may appear
different sizes on bigger teeth. Dentists may be deciding that correctly sized holes drilled in the teeth need to be made larger, not because they do, but because perception is a tricky thing. Illusions affect not only big ships and teeth but also your future. The End of History Illusion is our
tendency to think of ourselves today as somehow done. Sure. I went through a lot of personal growth
and changes in taste in the past, but today, who I am now, this is pretty much the final me. But that’s not true. Studies have consistently shown that
people underestimate just how different they will be, say, 10 years in the future, even though they can easily point out
how much they’ve changed since 10 years ago.
I like how Daniel Tomasulo puts it: “We believe we are going to live, love, and long for where, who,
and what we are thinking about right now.
But the research says it just ain’t so. This too is a transient state.” Yogi Berra put it even more succinctly: “The future ain’t what it used to be.” Their advice is don’t imagine your future. Look at other people and their
experiences instead, take their advice. Your imagination is just that, their experiences are actual data. Well, of course, it’s not that simple. Which brings us to our final illusion: The illusion of control. Named by psychologist Ellen Langer,
it’s our tendency to believe we control the outcomes of things. We demonstrably don’t. It can help motivate us to not give up and, in healthy people at a healthy level, it is optimistic self-appraisal. But it’s a lie. In one study, traders in the City of
London’s investment banks were shown a graph of a real time stock price and given three buttons that secretly didn’t do anything to affect the price.
But they were told the buttons might have an effect – try them out, see what you can do. Afterwards, the traders were asked to
rate how much they felt they had been able to control the stock price with the useless buttons. And it turns out the traders who reported the greatest
sense of control over the stock price were the ones who scored lowest
on risk management tests and, in the real world, contributed the least to their company’s profits and in terms of salary made the least money. It’s kind of a bummer.
The illusion of control is a nice feeling but sometimes it’s fine,
sometimes it even pays handsomely to admit you don’t have control. And as always, thanks for watching.

  1. I hear honesty, and the word of God through your teachings. I pray to further your effect, to your cause to bring true awareness forth brother.

  2. Me: I want to make a video with optical illusions
    Me: watches the video
    Me: This just made my life a whole lot easier.

  3. The best example of illusion of control I think is throwing a pokeball and the different things people mashing b .

  4. Who else read the paragraph word for word at the start and it didn’t move?

  5. 1:23 I thought it's moving by edits and when I pause it. its really moving

  6. This is Greg 👨🏻‍🔧

    He has 0 friends

    1 like = 1 friend ❤️❤️

  7. "… the traders who reported the greatest sense of control over the stock price, were the ones who scored lowest on risk management tests and, in the real world, contributed least to their company's profits…"

    That sounds sssooooooooo familiar.

  8. I’ve noticed a particular characteristic that Michael has…he has a distinctive over-pronunciation (and maybe it’s not even over-pronunciation, but maybe it’s just the perception I get) of the R sound in words. I can’t duplicate it myself…I’ve tried…so I think it’s just some kind of perception that his speech gives because of maybe his accent or just the particular way he talks…but I notice the Rs in his speech more than anything else. I’ve heard this particular speech characteristic in a few actors, but I can’t think of their names at the moment.

  9. We go from circles moving on my screen to the Titanic sinking to imagining the future. Wow.

  10. These are all messages from A man named Michael to a dude named Vsauce. He says hey Vsauce! Michael here. Indicating that I am baked as fucked.

  11. Soviet Union: Haha let’s fool everyone with an illusion that we have more bombers than we really have

    U.S: Creates more and more bombers and eventually has 2,000 bombers

    Soviet Union: “It’s just a prank bro”

    This is just a joke, please do not take this seriously

  12. Underage Kids:So this is what it feels like to be drunk?Awesome!
    18+:Slipping around the room.

  13. 1:24 whene you squit the blue ceircles are not moving anymore

  14. Illusion does not mean to mock and have fun with. Where in the fuck did you come up with that? An illusion is something that looks like one truth but is a different truth. Il Lusion. False light.

  15. Thermal inversion is bullshit. We are seeing the SHIP and the water is masked by the atmosphere and light. Because the earth is a flat plane disc. Sorry. But you have to prove that shit. I don't. Because I am observing a flat plane. You are the one saying the observation is an illusion and having to come up with inversion theories to provide evidence to support that claim. That is not proof. An Ex PLANE ation is not proof. It is just an attempt to find another way to make your theory work in opposition to an observation

  16. 5:40 This channel has been fairly credible, but unless I'm missing something there's no way the Titanic sank because of an optical illusion; the iceberg was struck, in the dark, at 11:40 p.m. on April 14, 1912.

    Also, how do anamorphic illusions save lives?

  17. The reason the Titanic sank, is because the person controlling the ship was being warned about the big iceberg ahead, but he kept on telling them and I quote, “Shut up. I am busy.” That’s all I know though, I don’t really know if it’s true or not, I just found it in a book about the Titanic.

  18. i know this is sad but id rather go out by doing something badass than dying of cancer. sucks cause i think i might have cancer

  19. Michael: "This is pretty much the final me"
    Me: expects *or is it?*
    Michael: thats not true

  20. Just came here for a peaceful test on my eyes.

    Came out with an existential crisis on my eyesight…

  21. Everything we see is an illusion, as it is just waves received by our retina turned into a so called image or event. We are not really seeing the object or event, we just collect electromagnetic radiation called light bouncing off this so called event/object and our brain thanks to our eyes messages form a image/picture……… ha ha enough of me giving you my illusioned message, cheers Thanks for video Michael from Michael

  22. At the end of history bit he says how people think "This is how i'll be in the future", but for me I often imagine and am quite fearful (probably irrationally so) of how different I may be in the future. Anyone else feel the same? Like I fear that I wont enjoy the things I do currently in the future, even though if I indeed don't enjoy those things in the future, it wont matter….because I don't enjoy them, and that somehow scares me I guess.

  23. Soldier: Sir, how to we disguise and keep enemies from attacking our ships?

    General: Give em the ol’ razzle dazzle

  24. 4:02 "did you hit something larry"?
    hits kid
    – "oh no martha, just another one of those road paintings they put up".

  25. Me: bro your lagging
    My friend: my internet is bad at the moment, what do I look like?
    Me: you look like 6:18

  26. If you are a fan of Formula 1 or football (soccer) skewed decals have been used for a long time for advertising.

  27. The youtube thumbnail appeared moving so I clicked here. I couldn't see any of the other illusions. What does it mean to not be able to see an illusion?

  28. In my side recommendations there is a Vsauce video titled "Should You Eat Yourself". Please send help
