Historian Nicholas Goodrick-Clarke analyzed the topic in his 1985 book "The Occult Roots of Nazism" in which he argued there were in fact links between some ideals of Ariosophy and Nazi ideology. He also analyzed the problems of the numerous popular occult historiography books written on the topic. Goodrick-Clarke sought to separate empiricism and sociology from the modern mythology of Nazi occultism that exists in many books which "have represented the Nazi phenomenon as the product of arcane and demonic influence". He evaluated most of these as "sensational and under-researched".
