I've been reading this forum for some time, and this thread I have found particularly interesting. As an undergraduate student it is very clear that Psychology is not the only field that has become female dominated. I was a communication disorders and sciences major before switching (a degree in that leads you to grad school to become a speech pathologist or audiologist) and only two men were in those classes out of about 100. The same thing can be said about pre-physical therapy, pre-occupational therapy and even biology at my school. The vast majority of students who want to become physician assistants, lawyers and anything else that requires a higher degree are now women. It's not just at my school, there are numerous articles that support this trend in higher education. A professor once told my mom that the average graduating grade point for women is almost one full point higher then men's graduating GPA. All the women that I talk to know exactly which career they want, where they want to go to grad school, etc. All my male friends and classmates tell me, "Uh, I dunno." when we discuss are futures. Also, I am an honors student. I don't think there are over 20 men in the honors college with several of those men being forced to drop out due to low GPA's every year. Even as a woman who is very pleased to see other women gain better employment and getting an education, I find this to be almost horrific. There is no reason why any discipline should be male or female dominated as it does nobody any good. There is also no reason why fewer men should be graduating from college and getting masters and PhD s.
So to sum up my point after all this yapping.
The field of psychology is not the only field in the world that is becoming male dominated, it is a trend that is being seen in a lot of disciplines, especially in health care. To fix this we need to address the problem that fewer men are now graduating and earning higher degrees. If we do not fix that, we will never fix the gender imbalance.
