So what if the experience men call "pain" and the one women call "pain" aren't actually the same thing at all? There's some evidence from lab rats that this might be true.
A growing body of evidence—including a 2012 analysis of 11,000 patient records—indicates that women are more sensitive to pain. In fact, they may be hardwired to feel pain differently. Last year, Magil and a plethora of co-authors published a study showing that female lab mice actually used different cells to transmit pain signals through their spinal cord. And while no one has confirmed that this is also the case in human females (paging the ethics committee…), Magil says evidence in animals is both compelling and growing stronger.As the article says, it may not be true that humans differ in this way just because mice do. Considering the possibility, however, raises some really big epistemological and metaphysical questions. Maybe some ethical ones too, especially for the utilitarians.
Well, that's one more reason not to be a utilitarian -- a matter already over-determined, in my book.
