approval voting gives you MORE information about opinions, even if this is counterintuitive.

this is because:

1. the IRV tabulation algorithm discards a lot of useful information. (there are better ways to tabulate ranked ballots.)

2. strategic exaggeration of rankings is more distortionary than with approval voting.
