Runic divination, "runecasting", is not "fortune telling". Runecasting works deeply with the subconscious. The rune pouch with its runic symbols represents the entire universe. As one poses a question, one's entire conscious and unconscious mind is focused toward that question, so that the runelots selected are not truly random selections, but rather choices made by the subconscious.
Runecraft operates on an ancient form of psychology. Even back in Viking times, there was a remarkable understanding of the human psyche. They recognized cause and effect, and the interconnectedness of all things. The word to describe this interconnectedness was "wyrd", which was eventually perverted into the modern meaning of "weird". It did not originally mean something unusual or strange. Rather, it referred to the far-reaching effects of that which one does. The concept of "fate" was also not as we know it now. Instead of a helpless predestination, "fate" meant a destiny created by one's earlier actions. Wyrd was pictured as a web, like that of a spider. The symbology is excellent. When the spider steps onto a thread (a path) the vibrations affect the entire web and that which is contained within the web, just as our actions affect our immediate world and those around us, and the actions of others affect our lives.
When one does a runic reading, one usually addresses a particular issue, and examines the past, the present and the "future", or rather "what will be if one follows the path one appears to be on". The future is always perceived as mutable, changeable. The runic reading is done as an evaluation process, not as fortunetelling. One has an opportunity to look at what has occurred in the past (regarding the issue being questioned), what is occurring right now, and what direction one is headed.
A runecaster does not see the future. He/she examines cause and effect and points out a likely outcome.
Not exactly occult, is it? It's not supernatural and it's not very mysterious--although the uninitiated considered it a delving into mystery, much like a patient of a psychiatrist might. It's certainly not magical or demonic. Instead it is a methodology for examining the path one is on and what the effects might be, by making use of one's subconscious (i.e. an "intuitive perception"), unfettered by limited conscious belief systems.
Dowsing, or "divination" by bent stick or pendulum is similar. It is not supernatural. It is, again, a manifestation of one's subconscious. All "intuitive perception" is such. Nothing magical about it, merely a means of awakening one's right-brain.
