You can see more here https://​​www.lesswrong.com/​​posts/​​2jTQTxYNwo6zb3Kyp/​​preliminary-thoughts-on-moral-weight and on the links at the bottom of that post. It would change things quite a bit. We have not done the calculation but off the top of my head I would expect it would impact insects most significantly with other animals moving up or down a category e.g. cows might move to mid but I would not expect them to move to high.
