Quick response: I seem to recall B&L saying that in their polling data,
Approval responses showed sign of many voters using what I've been
calling "scenario 3" reasoning, i.e. relative ranks (where rated/graded
systems would fail IIA). They then argued that this means you have to
have a properly phrased ballot to get the voters to consider grading
against a common standard rather than ranking relatively, and more
specifically, that Approval's two grades were not sufficient to do
permit that kind of mindset.

If that's true, then there's some kind of threshold of number of grades,
below which there aren't enough grades for the ballot format to
encourage grading against a common standard. So three-slot methods would
have to be tested to see if voters would vote grading-style or
relative-rank style with three grades, or if three grades are still too few.
