“Your ability to ability to be treated favorably by people in your tribe” gives me actual information to work with.
This ignores the unpleasant aspects: your ability to mistreat other people in your tribe, and your ability to not be mistreated. If one person gains the ability to be favorably treated, others are losing the ability to mistreat.
I think it still applies. I suspect that the two strangers who both start with some mutual respect would both tolerate slightly more rudeness than the ones without.
