THREAD: My Top 12 Favourite Perceptual Illusions

1. A great example of how expectations guide perception.

2. The horizontal lines in this image are all parallel. HT @victoria1skye
3. The circles in this image are all the same colour.
4. This isn't a GIF – the movement is all in your head.
5. This looks two photos of the same road, taken from different angles. But it’s just the same photo twice.
6. We don't directly perceive how light or dark objects are; the perceptual system makes an educated "guess" based on the lightness or darkness of the surroundings. HT @AkiyoshiKitaoka
7. The Dynamic Ebbinghaus: The orange circle doesn't change size.
8. The Dynamic Müller-Lyer Illusion: The vertical black, green, and blue lines don't change size.
9. You can make the train change direction.
10. Rotating Rings: Every time you switch from looking at one wheel to looking at the other, they both change direction.
11. The Spinning Dancer

If you look at the dancer on the left and the one in the middle, the one in the middle spins clockwise.

If you look at the dancer on the *right* and the one in the middle, the one in the middle spins counterclockwise.
12. Stare at the centre of the top image for 20 seconds then look at the bottom image...

Ivor Cummins has been wrong (or lying) almost entirely throughout this pandemic and got paid handsomly for it.

He has been wrong (or lying) so often that it will be nearly impossible for me to track every grift, lie, deceit, manipulation he has pulled. I will use...

... other sources who have been trying to shine on light on this grifter (as I have tried to do, time and again:

Example #1: "Still not seeing Sweden signal versus Denmark really"... There it was (Images attached).
19 to 80 is an over 300% difference.


Example #2 - "Yes, I'm comparing the Noridcs / No, you cannot compare the Nordics."

I wonder why...

Example #3 - "I'm only looking at what makes the data fit in my favour" a.k.a moving the goalposts.

• These five faces are symbolic of the five primordial elements called पञ्चमहाभूत:' which makes up the entire existence.

• These are the elements of SPACE, FIRE, WIND, EARTH & WATER.

• All these five faces shine with three eyes 'त्रिक्षणै:'.
