Which way is she spinning?
By the way, there is one correct answer
Not a trick question. She is definitively spinning either clockwise or counterclockwise. Which one is it?

Extra credit for doing it in your head.

Puzzle by @Cshearer41
The first 20 answers are all wrong. There is an exact answer and it's not 1/2.
0-for-40 now. You only need 9th grade math and with some effort can do it in your head.

Politics is like chess. Being in the center of the board, with mainstream positions, is a strong strategic position.

People, politicians, factions, and movements whose pieces are out on the corner of the board have three options:

1/4
1) Stand firm on your positions, and try to change enough minds that the chess board moves towards you, until your pieces are in the center

2) Compromise on your positions and move your pieces closer to the center of the board

2/4
3) Start moving your pawns like knights and your bishops like queens and see if you can get away with it

When a person or group is doing #3, the particulars of their stances are irrelevant. Everyone abiding by basic liberal rules should unite against the cheater.

3/4

The human psyche has weather. When we feel bad about the present and future, it’s cloudy in our psyche. When our psyche is cloudy, it colors everything. Things feel gloomier, angrier, scarier, and more depressing. This of course has all kinds of negative effects on behavior.

/1
Likewise, gratitude and optimism open up a bright blue sky in the psyche. This feels blissful and energizing and fosters kindness.

These behaviors generate more of the weather that produced them. So psyche weather is contagious, and it can spread like an epidemic.

/2
People know something is wrong in society right now but it can be hard to articulate.

I think what sucks right now is that a massive epidemic, maybe pandemic, of dark cloudy psyche skies has spread.

(Covid doesn’t help, but this has been going on a lot longer than Covid.)
