Over the last couple of years, in an effort to know a bit more about art history, I have been adding the works of famous artists to Supermemo. Among my favorite artists is Edward Hopper; even if people are present, his paintings evoke a calming atmosphere of solitude that I would love to escape to and spend time in.
Recently I had a conversation with someone about art history. I didn't realize until the subject came up that each of the paintings that I had put into Supermemo occupied a special place in my mind. Although I did not paint those pictures, I felt as though they were "mine," some sort of personal possession.
This leads to an interesting conclusion/question: If Supermemo can "force" one to become familiar with something (The works of a particular artist, for example), can Supermemo help shape your likes and dislikes? I think so, albeit in more subtle ways. For example, one could not simply make a flashcard that says, "I like Edward Hopper," and suddenly you enjoy the works of Edward Hopper; but you could learn about the artwork of Edward Hopper (What is the name of this painting? In what year was this painting made? etc.), and as time goes on, you become more and more familiar with his works. Eventually Edward Hopper's art will become like a familiar art gallery in your mind, and when you see one of his works "in the wild," you will say "Hey, that's a Hopper painting!"
To summarize: Spaced Repetition easily creates points of reference. This breeds familiarity, which begets a fondness for the subject under consideration.
