Ufology on the whole makes no claim to be in and of itself "sceintific". It does however advocate critical thinking.
On the contrary, I have seen many claims made under the rubric of "ufology" that purported to be scientific, but lacked basic critical thinking skills, let alone sound scientific methodology or verifiable evidence.
What you're doing here is a bit of PR work: promoting your own justification for this broad pop-culture genre which is highly inconsistent with the majority of output from most professional ufologists.
Despite having chosen "ufology" as your username on this message board, you are not the founder or official spokesman of "Ufology." "Ufology" is not a unified, self-regulated organization with a singular, specific ideological position. Rather, it's a general subject of interest composed of perhaps millions of individual enthusiasts worldwide, promoting many diverse viewpoints from the fairly rational to the laughably outrageous.
The sole unifying fator among all these diverse adherents is a common interest in promoting an unsubstantiated body of popular folklore. Because ufology primarily concerns itself with the validation of unverified urban legends as fact, that alone is the definitive factor that inspires me to brand it a "pseudoscience." I look at ufology websites, watch ufologist spokespersons on TV and YouTube, read books and papers on the subject, and from those sources it appears obvious that the vast majority of this material is every bit as pseudoscientific as other fringe "fields of study" like ghost hunting, cryptozoology, cryptoarchaeology, etc. If you consider those pursuits to be "pseudoscience" (as I do), then ufology also fits that bill.
So just because a ufologist quotes a scientific study doesn't make ufology a pseudoscience any more than it would make journalism a pseudoscience if an investigative reporter uses it.
The same could be said for history and a number of other fields of study.
Those are really weak analogies, considering science journalists, ufology journalists, science historians and ufology historians all exist. Whether or not writers quote scientific studies in their work is not the central issue here. It's the general practice of promoting unscientific, baseless claims (a.k.a. "woo") as verified facts.
To cite your former example, an investigative journalist could certainly engage in the practice of pseudoscience (as many have) by using scientific-sounding language to promote unscientific ideas. Of course a sole individual behaving in such an erroneous (or outright deceitful) way wouldn't justify an indictment of the entire journalism industry.
Likewise, a real scientist like Jacques Vallée or Linus Pauling could conceivably exploit the authority of his distinguished scientific career to promote pseudoscience on the side, as Vallée often does when he forwards the very unscientific opinion that UFO sightings may be extraterrestrial or inter-dimensional craft, and Pauling did with his "Vitamin C megadose therapy". It happens. But all of science isn't to blame. Every individual is ultimately responsible for his or her own actions.
On the other hand, an entire industry built around promoting pop-culture mythology to peddle TV shows and books full of fake science fully deserves the designation "pseudoscience." It's one thing for a few credulous fools to believe that eyewitness UFO anecdotes are proof of alien visitation, but the real damage happens when our culture's science literacy erodes to the point where people are unable to distinguish science from folklore, reality from fantasy.
It can't be just because of the frauds in ufology. Historians, reporters and even scientists have also had fabricators and forgers, but the rest of us haven't slapped some derogatory label on history, journalism and science as a result.
Again, you're conflating the issue of frauds perpetrated against a specific realm of established science, with an
entire field of study dominated by fraud, deception, faulty logic, bad science, unverified anecdotes, and even insanity.
If ufology is indeed a legitimate field of study, then where are its results? People have been studying this "phenomenon" for well over half a century now. People keep reporting UFO sightings, abductions, and the like. Books keep getting published, movies keep getting made, yet there's not a single shred of evidence that UFOs are anything but instances of very normal objects and phemonena being commonly mistaken for extraterrestrial craft or paranormal forces.
Under all the self-important varnish it's never really any different. Someone always just wants a nice big fat wide brush to dirty-up the other guys with to make themselves look better.
Aw, come on. It's not so bad. The accusation of "pseudoscience" may seem rather harsh and the accusers may sound arrogant and self-righteous, but there are far worse epithets one could be branded with, and you even admitted that it doesn't really matter all that much.
To clarify your position, let's cut through all the semantics. Would your definition of "ufologist" include a professional astronomer who writes a blog dedicated to debunking UFO sightings? How about a person who picks up a Whitley Strieber book to read purely for entertainment purposes?
And what about me? I posted last night about the UFO sighting I witnessed with my friends on a farm in Michigan. Does my meager, half-assed investigation make me a ufologist in your view?
