I was filtering on people who answered any branch of a related closed question with negative Accuracy score.
Going forward I will filter on people whose sum of Accuracy scores on all bins of related questions that they forecast is negative.
Also in sorting and weighting I will look at sum of Accuracy and not average Accuracy. This does not amount to the same thing as average for sorting purposes, because different people forecast different subsets of questions. Using sum rather than average also rewards people for choosing their battles wisely. I don’t: I forecast all questions.
I know what I was doing before is wrong because I was picking myself up on scans and I know that my Accuracy scores in all but a few questions are terrible.
