Wood, Kressel, Joshi, and Louie report that published, but not unpublished, studies of masculinity, dominance, symmetry, and health preferences show significant overall effects of cycle phase. They interpret this as evidence that reports of cyclic shifts in mate preferences are artifacts of publication bias. I will first discuss why these conclusions do not necessarily follow straightforwardly from their results. I will then discuss their findings for health preferences specifically, concluding that their dismissal of a significant overall effect of cycle phase (...) is unreasonable. (shrink)

In this commentary we suggest that Fincher & Thornhill's (F&T's) parasite-stress theory of social behaviors and attitudes can be extended to mating behaviors and preferences. We discuss evidence from prior correlational and experimental studies that support this claim. We also reanalyze data from two of those studies using F&T's new parasite stress measures.
