I came across this interesting list on a conservative website for women. I have no idea where they obtained their information. I might contact the editor for sources. However, while this list might look strange to many, it looks about right to me. There's this misconception that STEM majors lean right. It's possible that they might lean more fiscally conservative, but to assume that they would be more socially conservative would go against statistics in other areas. Not only are scientists more likely to believe that current global warming is caused by human activity (they don't even see this as a political issue, but it has been politicized), American scientists are also more likely than the general population to be atheists and agnostics. Post-graduates and those who are non-religious tend to be pro-choice.
I should note that being religious does not always lead to being socially conservative. Education majors are very religious, but they are also very liberal.

In U.S., Nonreligious, Postgrads Are Highly "Pro-Choice"
Here's another interesting study that found that biology and physical science majors are just about as religious as they were when they started college, so it look like their studies may have little to no effect on their religious beliefs.
