This is awful because the balls are not being dropped in the center. Instead, the color of the end slots should change based on probabilities. The skewing of the entry point implies a bias in prior distribution, which is not the right message.
They are being dropped from the center of the probability distribution, not the center of the electoral vote threshold (which would be nonsense).
> skewing of the entry point
Skewing from what?
> bias in prior distribution
That's the point!
> color of the end slots should change based on probabilities
The height of the bar changes based on the probabilities.
A biased sampling with uniform slots at the bottom shows the same thing, yes.
1. We’re dropping the ball at the position the polls (and our models) indicate.
2. The balls may end up in a different place due to any number of unforeseen factors (the pegs).
The probability is expressed by the number of times a ball ends up in each of the end slots. That's the whole point!
