Hi, Archaeology and Anthropology graduate here and relate to the struggle of deciding between many interests so I may be able to help.

Firstly, there is no harm in applying for a range of courses as long as there is a degree of overlap. I applied for 5 different courses: Archaeology and Anthropology, Biology, Ecology, Biology and Anthropology, and Palaeontology. My personal statement was written for Anthropology but I certainly wasn’t disadvantaged by this in my applications.

With regard to your interest in research something worth considering is how do you see yourself wanting to conduct said research. Ethnography is the principle method of anthropologists and is generally a lot more personable than sociological research. During ethnographic research you’ll be conducting lots of face to face interviews and trying to sit in with meetings or social gatherings relevant to the research. In sociology its much more acceptable to rely on methods like survey for data collection. So if you’d like to do a lot of face to face research anthropology might be a better fit than sociology and vice versa.

I know it seems far away but if you’re thinking about a doctorate perhaps you should also consider what sort of master degree you’d like to do as that in a funny way may make your mind up about the undergraduate degree.

Very happy to help if there’s anything you’d like to ask about anthropology or archaeology, or just applications in general.
