There is a difference between social science and humanities. Social sciences mainly refer to law, economics, politics, sociology and demography, while humanities mainly refer to philosophy, literature, art and religion. To improve humanistic quality, we should study both humanities and social sciences. But social studies are not as interesting as humanities, such as economics, which involves advanced mathematics.
