Four studies examined the hypothesis that honor norms would be associated with a pronounced use of patronyms, but not matronyms, for naming children. Study 1 shows that men who endorse honor values expressed a stronger desire to use patronyms (but not matronyms) for future children, an association that was mediated by patriarchal attitudes. Study 2 presents an indirect method for assessing state patronym and matronym levels. As expected, patronym scores were significantly higher in honor states and were associated with a wide range of variables linked previously to honor-related dynamics. Study 3a shows that following the terrorist attacks of 9/11, patronyms increased in honor states, but not in non-honor states. Likewise, priming men with a fictitious terrorist attack (Study 3b) increased the association between honor ideology and patronym preferences. Together, these studies reveal a subtle social signal that reflects the masculine values of an honor culture.
