In the past month or so, there have been a couple of stories which are generally not helpful to science and honest research. The first being the Italian seismologists who were found guilty of not being able to project a volcanic eruption. Although that isn't directly tied to this particular idea, it is relevant in the larger picture and presents an interesting tangent...
In particular though, this is related to a study which looked at whether or not there was a specific factor which might be attributed to female voting preferences. The study was performed by Evolutionary Psychologist Dr. Kristina Durante of the University of Texas, San Antonio.
In the study, it found that females who were single and not using a birth control which impacted hormones and menstruation tended to be more likely to hold liberal ideals during ovulation than not. In contrast, married females held more conservative ideals during ovulation. There was no significant difference between the two groups while not ovulating. Participants were weighted regarding their age and background to correlate between similar socioeconomic groups (other than their marital status).
While the study generally explains certain differences between married and single female voters political leanings, when it was picked up by CNN a week or so ago - the webz exploded in rage (as much rage as a somewhat obscure evolutionary psychology study could generate). I would link to the original article, but CNN has since taken it down:

You can read one of the more in depth commentaries on the article here:

The problem, according to the detractors, had nothing to do with actual faults in the study or the methodology of it - rather that the study was done at all. Prominent feminist studies experts cited it as just another attempt to reinforce that women should not be allowed to vote and especially not be able to hold a position of authority because they are obviously irrational hormonal creatures. Lots of other individuals voiced similar opinions - again, without actually addressing any of the data presented or the methodology of the study.
On balance the actual impact on female voters is a wash. As the primary function is tied to ovulation, and given a more or less even distribution those in each group balance out those in the other group.
The funny bit is that in the 2008 election a study was performed which tested testosterone levels in male voters which found that those whose political candidates won their race had an increase in testosterone while those whose candidates lost had reduced levels of testosterone. That study also indicated that the level of change was enough to cause ED in certain individuals as a result of the lowered testosterone levels.

Further, one of the feminine studies experts countered that she didn't think that female hormones impacted women's votes any more than testosterone impacted the debate performances. The problem of course is that dozens of studies have shown that testosterone levels do impact debate performance (and other forms of posturing, both political...personal...and professional).
So, are the findings in this study or any other study which might deal with differences between sexes, ethnic groups, religious groups or other differential groups bigoted? I tend to take findings at face value. They are neither racist or sexist - just findings. In general they are not even a particularly important factor in policy decisions, and simply stand on their own.
