      ​@@ChristelVinotLarge grocery stores have an insane amount of money and effort put into psychological manipulation of customers.
      Whether that's through brands bidding on central shelf space, artificial scents in certain parts of the store, (typically bakery sections), things as simple as spreading out the most common purchases to make you see the entire store, it's quite interesting. While a larger cart let's you carry more, there's more to it than convenience. Look at how stores have few hand baskets, or put them well into the entrance past carts. That's so you don't use them and the other methods of pushing purchases aren't thwarted by limited space.

    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.

      What about the thumbnail for the video? In that, I saw it as very light blue and bronze. But in the video itself, the actual dress on his desk looked clearly dark blue and black, whereas the images he showed were more like a sky blue and brown. (At least, that how I saw it.) Admittedly, when this phenomenon was all the craze a decade ago, I saw it as blue and black sometimes, and at other times, a very, very pale (almost white) blue and gold or light brown. Sometimes I was looking at the exact same image, but in one instance, it would appear one way and on another instance, it would appear as the other. The funny thing was that once I looked, looked away, and looked back at it, it's appearance always remained the same. It was only if I completely went on to something else and stopped thinking about it, but then saw it again, it would look the other way.

      I recently came across the dress photo. I saw it twice in the same day but the color changed. I noticed my blue light filter was on when I re-viewed the photo. Turning on/off the blue light night mode made the dress change between black/blue to gold/silver at a push of the button. This likely factored in on people viewing the dress when it went viral.

    • @Hyperdriveuk

      It's just massively over exposed photo with 2700k lights... I put it on photoshop, make some minor tweaks and it looks just like the dress he has in the studio. Perhaps the white/gold people don't have the ability to process color like that... hence the "night vision" my brain just tells me... it's too light, so in the dark it's blue & black.

    Dr. Pascal is one of those people that is so intelligent and has such an incredible mental architecture... that when he is talking, he knows the "full answer" in a matter of miliseconds, so he starts talking with increasing speed in order to "get to the point". The way he looks up and down repeatedly, shows a very polivalent, unrest brain. Many intelligent people do the same.

    For the dress:​ I can see black/blue and white/gold, and flip them at will. I'm not entirely sure how I make them flip, but it feels like I'm focusing on bringing forward the colors I want to see, or sometimes focusing on the lighter or darker parts of the dress, and then it abruptly comes into focus as the color combination that I intended. This is also the case with the pink/white, gray/teal sneaker photo.
    Admittedly, I initially saw it as white/gold, then after I scrolled down a page and back up, it was black/blue, stuck at black/blue for a few minutes, then it kept flipping nearly every time I saw it, until I could eventually see both entirely at will.
    With the sneaker, I could immediately flip it at will, perhaps due to the experience I had with the dress?

    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

      Human's relationships to numbers is actually pretty trippy all on its own...
      There's an indigenous tribe in South America, that only has 3 numbers in their counting system. 1, 2, and "Many" in their language... I'm not sure where that gives your theory credibility (exactly) though I know it adds something to it...
      The concept of "zero" is also fairly recent for "official arithmetic"... Negative numbers even moreso. Up until that, if you had "zero" of anything, you simply didn't have it at all. There was no need for "zero" and even after it came to academics, it was largely an academic exercise until the lawyers and accountants could start to make heads and tails out of the concept of "negative" numbers, meaning you could owe something you didn't already have and had no real expectation to speak of.
