I did some digging and the jury is also always from that planet and also quite racist. It’s not only always someone from earth but also from the human race.
That’s why analyzing power structures is so crucial. I don’t believe that they actively exclude non earthers or non humans, but the jury is more likely to choose their own kind and the people putting together the jury are as well.
Iirc there is a strategy in the US in one team sport for management to have a quota, not in outcome but the shortlist has to contain one non human (or non white, I’m not sure) and that alone raised the outcome because it made people seen that were invisible for the committee before.
