Thanks for your question, Moritz. We distinguish between negative results and unknowns: the former are those where there’s evidence of the absence of a trait; the latter are those where there’s no evidence. We penalized species where there was evidence of the absence of a trait; we gave zero when there was no evidence. So, not having many negative results does produce higher welfare range estimates (or, if you prefer, it just reduces the gaps between the welfare range estimates).

Thanks for the explanation Bob. That absolutely makes sense! I was somehow assuming that negative results would count as zeros as well.
