Both require motor skills, i.e., lifting a finger requires muscles to move.
Already, the theory is on shakey ground.

I bet I know the cause of the anomaly, not enough data. I strongly suspect
that if enough data was taken, we'd see that the difference between Black
and White would be less than the degree of confidence for the measuring

Why do I think I could conduct the test using NBA players and people of
average height in the general population and "prove" that taller is smarter?

Once again we see, "Pick a conclusion then acquire/manipulate the data to
support it."
