When i do the desert scene, i see a red desert on the left, i do ave eye problems, does anyone know why this might be as I have intermittent estropia?
Alex Panoussi (6 days ago)
i mean, after watching the white dot between green and red, i thought the left desert was red and the right normal so maybe something went wrong😂
What happened to his shirt? Is it just me or it's some optical illusion?

the first experiment, he says "pretty even split" ... not at all, it looked like more people raised their hand for the grey one as for the green and orange ones combined!

"light we see is meaningless" 4:15 I say that's an overstatement... using one instance of inaccurate light reflexion to claim that "everything we see is meaningless" is the type of arguments that liberal millennials use to "back" their flawed views.

I think i like a sponsor ad talking about USA creating 45% world air pollution in a TED talk about illusions LOL

This is a weak presentation. The filtering of color through the eyes is relative to aperture (iris) and the cones. Block one eye in bright sunlight for a few seconds. The blocked one changes its perception of color when it is opened again. Wear a red and green pair of 3D spectacles and the same, almost instant, adjustment occurs. As others have commented, the grey spot that is replicated on the second bottom line is the point of this exercise, not what he did with the top grey spot. Regarding hearing and sight, the amazing thing is that without sight there is more space for sound and memory in the brain. Some people can sense color through their hands. This shows the spectrum of adaptability of our senses. I can hear bats tweeting their sonar. Others think I am imagining this. Out of sight out of mind. I have had my hearing tested and it is well above average. I have protected my hearing. I am a jazz musician. Maybe I am an alien. ho ho

He's got a soothing voice, but his accent seems to jump around. A subtle mix of English/Irish/American

And we still accept "eye witness" evidence in court? Dawkins has also talked about this. Totally unreliable. Inadmissible.
Jordan Munroe (16 days ago)
Not everything this man says is quite accurate. The red/green desert color swap has nothing to do with the brain at all. It is cone fatigue. He is a salesman. When you watch a ted talk, see not as experts but as salesmen marketing their ideas. Question everything.
TheAmazeer (16 days ago)
Color changes regarding if they are lighted with white light or another ... Or if context around it is different.. colors are lightwaves

Amazing how just 1 button can make me think this guy is a rapist

His accent is so weird BUT, intresting video oh wait Why is your shirt unbuttoned? WEIRD

Jon Miner (21 days ago)
No it isn't. Our visual cortex is trying to show us what we can understand. And no, the open shirt is not professional.

Any man that shaves his chest is a cheeseball. Aside from having open heart surgery, there's no good reason to lather up your damn chest. He's gay.

Hold up, 6:20ish, with the desert scene, my brain switched the colours. Red went left and green went right. Why??
Jon Doe (1 month ago)
Perhaps, "just" because the nerve cells in our eyes that see red/green were still being stimulated, when you/we looked down at the desert scene.

"As a more contemporary artist said: art is to demonstrate the fragility of our senses. This is complete rubbish". I'm sorry, what? Surely this whole talk was demonstrating exactly how fragile out sense are? How malleable and easily fooled they are. How is that not demonstrating their fragility?
jamotide (11 days ago)
He said it is the brain that is messing up the perception, the senses are not the problem.

Is it just me or did he just take like 19 minutes to explain what anybody with vision already knows. Of course colors influence other colors and the level of light plays into it as well. TED talks are getting worse and worse.

You may think his shirt is unbuttoned quite a bit, but when you include the context of his shirt only having 3 buttons, you'll realize that what you perceived to be reality was simply just a limitation of your senses.

hofifut (2 months ago)
well, a guy gives us a talk about optical illusions then says in his first demonstration about the colored circles "OK, so 3 even splits". Uh dude.... there wasn't 3 even slips. Most of the people chose the grey. And very few chose the green. Yet he fools himself by saying roughly about the same amount of people chose the different colors

nothing worse than a smartass audience :D

Beau Lotto sounds like a made up name.
merry chase (3 months ago)
Yep, the shirt is a silly, manipulative trick.
I'm not saying he's been tweaked & awake for a day or two -he just looks, sounds & acts like he has. SLOW DOWN please. I had to keep pausing or repeating certain bits to see what everyone else was seeing. FINALLY I played it at .75. WORKS!! A POINTER would go a long way in directing viewers to exactly which bits objects he's referring to.

the experiment at 5:30 doesn't work for me, even after stopping the video and doing calmly for a minute, the image i see then is the exact same i've saw at start, no changes.. yea, i'm different! :D (all the others works "fine")

Were these two videos related. Was the research that Lotto does helpful for the computers interpreting the optics from the cameras?

Dave B (4 months ago)
The red and green panels don' train your brain to see another color, he's incorrect. It's a chemical change occurring on the retina, where the red receptors are desensitized through oversaturation, and so with the green on the left. It doesn't become your new normal, as it really has nothing to do with the brain. I leaned this decades ago.

stockholm is a tiny place. implement this in america which is rougly 50000x larger and you get issues very quickly. when our 1 country is almost as large as all of europe, well of course we will produce a large percentage of the worlds pollution. its like saying "breaking news, russia makes up a large percentage of snow covered land." a bigger bowl can hold more water essentially.
