Being a category including Ufologists, be they degree'd or no, who've endeavoured to understand the U.F.O. phenomena, and engaged themselves in writing, lecturing, or pure research effort toward that end. For our purposes, we hold Ufologists to be a class of agnostic or unconvinced researchers, compared to Saucerians who assert there is a known answer, either by virtue of their being a contactee or simply accepting contact has taken place. In some cases, articles will be filed under both categories, as in cases where a person who shifted in the duration of their time in the field, sometimes by becoming a contactee themselves, or for persons who hold that contacts have taken place in the past but may be skeptical of contemporary claims.
