Which hemisphere of your brain is stronger?
Which way is the dancer spinning, clockwise or counter-clockwise:
If you see her spinning clockwise that means the right half of your brain is dominant. If you see her spinning counter-clockwise then the left half of your brain is dominant.
If you can focus and see her spinning the other direction then you are fairly equally balanced left/right.
That is strange. I can see her spinning both directions depending on how I look at her. I can switch her at will. I would love to see how she was made! Since the eyes are basically reflectors, they obviously can’t be giving any false information in and of themselves here. Our brains interpret the information to give us our initial perception of what is going on, but they eyes see the same thing either way. This is an interesting topic for philosophy.
