```Valuation can be ordinal, in that you can know that 3 is more than 2.
There are two questions before us: Which voting method collects more data?
Which tabulation method picks the best winner from that data?

Which voting method collects more data?
Cardinal voting collects higher resolution data than ordinal voting.
Consider this thought experiment. If I give you a rating of A:5 B:2 C:1 D:3
E:5 F:2 you should create an ordered list from that -- AEDFBC. If I gave
you AEDFBC you couldn't convert that back into its cardinal data.

Which tabulation picks a better winner from the data?
Both Score and Approval voting pick the person with the highest votes.
Summing ordinal data, on the other hand, is very complicated, as to avoid
loops. Methods like Condorcet or IRV have been proposed to eliminate those
but ultimately they're hacks for dealing with incomplete information.
