--well, the voters were not biased toward Ns - they were biased toward Ys!

However, I agree that because this IS made-up data,
it may not have a great deal of relevance to
the real world.

As a matter of principle, though, it seems disturbing that Y-biased
voters could elect NNNN. But as a matter of practice, it perhaps is
rare enough that it has little impact.

--definitely true. They were constructed to demonstrate the paradox
could happen.

I would like to know more about how common this is and how serious it
can be and for which
voting methods.
