The problem with paranormal research (compared to other scientific research such as astronomy) is it's difficult to come up with a starting point. What I mean is, we know there's a whole universe beyond the atmosphere of Earth so we already know a lot about it - through centuries of studies and empirical evidence we know about planets and stars and galaxies. We know some physics and a lot about the natural forces of the universe. So we know there's an infinite amount of exploring to be done to learn more about all the things in that infinite realm.
But with paranormal stuff we don't really know where to begin because there's no observable structure, patterns, physics or predictable cause and effect.
With stars and planets - they're already overhead (relatively), they're already there, we KNOW this is true, we just have to find them and watch what they do.
But when a book flies off a shelf, what made that happen?
Was it a ghost, a demon, a possessed inanimate object, an unconscious telekinetic event, an ectoplasmic convergence, an inter-dimensional disruption, the results of an alien invisible ray gun, a family of Sasquatch moving through the area, a witch's curse, Scientology, the moving of the Holy Spirit, a simple act of gravity because the floor is not plum, an atmospheric pressure anomaly, a seismic disturbance, a mouse? A psychic telling you it was the ghost of a murdered person that's talking to them is a bit different than Galileo looking through his telescope over the course of months and charting the movements of shadows on a planet.
