The reason is that when occultists talk about them they usually include highly inaccurate information in them as well. In fact, from my experience, occultists take occult subjects and try to get physics topics to fit their models.
A good example is the way that occultists talk about higher dimensions. They will talk about dimensional densities, and how higher dimensions are better than lower ones. They then say that even physicists talk about a multidimensional universe. The truth is that although physicists talk about higher dimensions they are not talking about the same ones that occultists are, they are talking about dimensions that are compactified and require high energy physics experiments to probe them, such as being planned at the LHC at Cern.
The standards for occult belief are not those for science and because the occult has been so rife with fraud over the centuries, scientists shun any connection to the occult in most cases.
So there's your answer.
