Well, one could say that the ETH fits perfectly well within our current understanding of reality. It makes sense for us to assume that the anomalies we experience in the form ufos are interstellar travelers. A very practical and sensible approach. and this interpretation is not an entirely new one either, with accounts from ancient times speaking of visitors from other stars (starpeople), most often in the guise of gods.
The ETH I would argue, is more than ever firmly based within our cultural context, as well as in our scientificly oriented worldview. However that does not nescessarily make it a more valid conclusion. We constantly get bombarded with this concept in popular culture, and it makes sense for us to assume that other species might exist in other parts of the universe, and that they share our passion for exploration to the point that they find ways to travel to other planets that might be inhabited. We also assume, again with our own species as our only point of reference, that these guys come here using some kind of cool highly advanced technology, taking samples of the terrestrial flora and fauna. Today it is the western scientific way of thinking that provides us with our frame of reference from which to explain and interpret anomolous encounters. A thousand years ago, or rather for the most of our past it was mainly a religios worldview that was used to make sense of things.
One example of how the the scientific thinking is applied by many is with regards to strange and seemingly unexplainable phenomena. Many people instinctively make a sloppy attempt at scientific reasoning, dismissing anomalies out of hand because it is not "scientific" to assume that paranormal phenomenon exist. And this conclusion is often a knee jerk reaction, not reviewing the evidence to begin with. People tend to assume that they use scientific reasoning, even though it in reality may only be self deception, not using proper scientific reasoning. Thus the perception of a scientific thought basis has become an integral part of our cultural context, and not necessarilly real scientific thinking. I hope you get the gist of my argument.
The abduction phenomenon has a lot of tricky aspects to it, not the least which is a dubious source material, thanks to faulty research methods like "memory retrieval" through hypnosis. This has muddied the water to a considerable degree. This has unfortunately led to prominent researchers jumping to conclusions. I think we may need to take a step back and get our source material in check and establish a more fitting research method before we can make make further progress.
Regarding disclosure, or really the paranormal field in general and the ufo phenomenon in particular; I do not think that there is much interest among the populace. I have met a lot of people that profess that they simply do not give a fig what is going on. This leads me to believe that disclosure initiated by the public may never come to pass. Assuming that the government really knows anything conclusive, which I do not think is the case anyway.
