We should do some kind of statistical analysis of the objectively incorrect calls and their influence on every team's probability of winning. You could probably find a way to just check the numbers from those games verses objectively well called games and use Benford's law to see if there are any irregularities. I think it's obvious there is discrepancy. The really interesting thing would be proving it was implicit bias/institutional bias.
There was something similar done on this in Euro soccer last year. The synopsis was that with no home crowds due to covid, the foul differential between visitor and home dropped. I.e. more fouls called on the home team and/or less on the visitors -- than when there was a crowd.
The crowd influences the refs to help the home team.
