I just finished reading the paper. It is still in progress.
In my opinion, it is a good synopsis of the current understanding of "alien phenomena", based on the author's study on related literatures.
Although it is a very good reference point on the topic, the paper has its limit as a literature study. How many of the literatures the author listed can be viewed as providing mostly facts? I am yet to dig into each one of them, but I doubt if I have enough time to exhaust the long list.
The writing style reminds me of the academic articles in the "management studies/research" field, which is my major in university. There are so many "theories" and "schools" in that field. And a lot of "gurus", "scientists" and "researchers", too. Every article published in the management journals reads and sounds scientific, and was written in a scholistic language, yet the "researchers" themselves know perfectly how many of those articles are junk, and how few of them offer real discoveries of truth.
Almost all of the articles build their "working theories" based on other people's "theories", assumptions on assumptions, constructs on constructs. You see a grand mansion (or bubble) being built, while the foundation is far from solid as supposed. If the scientific value of a paper is questioned, in many occasions you would hear them say: "Well, you cannot treat management study as if it is natural science. Management study is a branch of social science, and social science is inherently fuzzy ..." Yeah. Then tell me how many managers in business are actually relying themselves on those profound theories and "findings"?? I doubt if most of them even read the academic papers at all.
I am new to the literatures of the alien phenomena, but I would rather not look at the investigation as if it is an academic discipline, nor would I start building "theories" on literatures. Not yet. Summaries maybe, not theories.
The UFO phenomena entail secrets and mysteries. They'd better be approached using forensic analysis and detective work. To disclose the secrets, we need action. Action such as the interviews by Bill and Kerry. Action such as the Disclosure Project.
The "murderer" has not yet been found, and we are far from reaching a verdict. The time is simply not ripe for us to "build" theories. We need more aggressive investigations.
Just my thought.
