 However, Cohen’s account may face some counterexamples. For example, humans are more likely to suffer from autism than other mammals, and so “humans are autistic” would seem to be falsely predicted to be a true (relative) generic, and it is hard to see how homogeneity could undermine this prediction (Leslie 2008). This example illustrates that unique possession of a property by a kind is not generally sufficient for the truth of a generic, yet the category of relative generic predicts that, modulo homogeneity, this should suffice.
