Although there is no guarantee our results would continue to hold as n increases, we can guarantee that using “Bad” judgments and transitivity will give us a slower rate of increase than making all preference judgments, and that using 3 If we need all of the judgments in order to train a ranking algorithm, on the other hand, we may not want to stop. Here or There 27 dynamic reordering and the early stopping rule will give us an even slower rate of increase. Furthermore, utility-based reordering produces that a set of judgments is maximally useful no matter when the judging effort is stopped.

Additional Analysis. The “context search” button, which allowed assessors to see twenty search results, was used a total of 41 times, slightly under once per seven queries. There was no correlation between the judgment interface and use of context search. After each query, assessors were presented with a feedback page to report their confidence in their judgments and their understanding of the query on a scale of 1 to 5, with 1 being least confident and 5 most. The median for both questions was 4, and despite not having “ownership” of queries there was no significant correlation between confidence and time spent judging.
