The Tweet GIF below gave a lot to talk about in the bird's network. It shows a circle formed by flashlights, but the lights and the direction of direction can be confusing at first glance. This happens because our visual field tries to be as “rational” as possible, trying to see exactly what is shown to it. Please note carefully:

And then? Which circle is spinning faster? Is there some kind of magic going on? Any computer-generated visual effects? It's actually nothing like that! If you answered that they have equal speeds, congratulations! In fact, the circles do not differ in this sense, causing some confusion in our minds. However, what is the reason for this to confuse our mind so much? Let's understand in the topic below:
The rapidly blinking flashes in the circle on the right make it look like it rotates faster too. Notice that in the other circle there are no flashes, and this comparison increases the other's sense of speed. In addition, the direction of rotation is another factor that differentiates one circle from the other, and this difference increases the perception of speed in the circle on the right.
And then? Have you managed to identify that their speed is exactly the same? Try to focus a little on the movement on the right, forcing your eye to ignore the flashes, so you can identify this common feature between them!
