Sex difference in attitudes toward paternity testing

We tested the hypothesis that men would favor routine paternity testing more than women by administering surveys. Indeed, more men (50%) than women (32%) favored paternity testing. We found no support for two secondary hypotheses about ways in which one's attitude would vary with income and marital status. We also present preliminary evidence that many males prefer preserving the ambiguity of paternity. (C) 2004 Elsevier Inc. All rights reserved.
