To begin, the book or movie genres that one likes are salient indicators of his/her personal interests. Along with the dissemination of information via both printed and digital media, people at present are unwittingly exposed to tens of thousands of assorted books and movies appealing to their fondness every day. An ensuing consequence of information explosion is a purposeful selection of what an individual chooses to include into his/her life - for example, the books and movies one likes. Although we can hardly tell a person's attitude towards logical reasoning when s/he reads only one Conan Doyle's work, such inference becomes evidently plausible when he/she is exclusively drawn into the whole series of Sherlock Holmes. Also, differing from a fan of religion and philosophy, a person whose interests reside in natural science may harbor particular tastes of motion pictures as well. Therefore, there is no denying that a person's interests can be safely demonstrated through various aspects of his/her tastes, and the books and movies one likes are no exceptions in this case.
