James Webb Space Telescope reveals that most galaxies rotate clockwise

I wonder if it’s already April’s Fools Day in some parts of the world. The hands of a clock move clockwise if seen from the front, but counterclockwise if seen from the back.

Coming from a place of complete ignorance, are there indicators in galaxies that determine a top/bottom for lack of better words?

I can’t think of any that would make much sense as top/bottom would mean that there needs to be a relative universal point to reference and as far as I know, that doesn’t exist.

The article states that the problem is that they looked at random galaxies, 1/3 were moving one way and 2/3 the other.

If the distribution was truly random, and the universe is isotropic, we should see roughly 50/50.
