I am currently a second-year computer-science student. However, I am interested in pursuing social science after I am done with my bachelor's degree. To be more specific, I am interested in the fields of Philosophy, Anthropology, and Political Science. To be able to do that, I have started practicing and improving my writing skills. Since I do not want to continue studying CS, I will not be looking for internships or any research experience in the field.
In the summer, I want to do things that would help me getting accepted in social science. But I do not know what I can/should do. In engineering, it is pretty straightforward: It is usually an internship in a company or doing research with a prof. What are the equivalent summer positions for social science students?
