- In their original PNAS article Macy and Sato (2002) make it clear that their main point concerns social mobility (see, for instance, the abstract and the last section). Their central claim is the non-monotonic effect of mobility: with moderate mobility, they maintain, trust can be established; with too much mobility, trust and trustworthiness are undermined — and therefore their "warning flag to the U.S." (7229). Exactly that effect turned out to be not replicable.
- In their reply, only paragraph 1.38 comments on our non-replicability result: they claim to like our contradicting result even more than their own from their theory's point of view. We are happy that we could do Macy and Sato a theoretical favour. It is a pity, though, that Macy and Sato do not provide any hint why under what we think to be their own assumptions their original non-monotonic effect of mobility could not be replicated.
