We all are to some point attracted to morbid, unpleasant, or violent things. It's the natural reaction of our brain, the natural curiosity that helps us prevent the real life danger and learn how to deal with real life unpleasant situations and also help us vent our own inner unpleasant feelings we need to deal with.
But why are some people attracted to dark sides for reality, more than others? Why some people enjoy horror, dramas, thrillers, while others find them unpleasant to watch and rather watch a comedy, or a romance movie? Why do some people rather listen to emotionally tensing, or raw and aggressive music and some people think that happy pop songs on the radio are the best they can get?
I have a suspicion this has to do a lot with imagination, empathy and intuition, but I have a hard time proving it. Have anyone ever made a research about such a fenomena? If not, what are your own thoughts?
