ALIENS EXIST – EYEWITNESS TESTIMONY SHOULDNʼT BE DISMISSED. Wendt and Duvall Ohio State/Minnesota, ʻ08] Alexander and Raymond, Sovereignty and the UFO Political Theory, Vol, 36, Number 4, August 2008 Most UFO reports consist primarily of eyewitness testimony. Although all observation is in a sense testimonial, by itself testimony cannot ground a scientific claim unless it can be replicated independently, which UFO testimony cannot. Such testimony is problematic in other respects as well. It reports seemingly impossible things, much is of poor quality, witnesses may have incentives to lie, honest observers may lack knowledge, and even experts can make mistakes. In view of these problems skeptics dismiss UFO testimony as meaningless. Problems notwithstanding, this conclusion is unwarranted. First, testimony should not be dismissed lightly, since none of us can verify for ourselves even a fraction of the knowledge we take for granted In both law and social science, testimony has considerable epistemic weight in determining the facts. While sometimes wrong, given its importance in society, testimony is rejected only if there are strong reasons to do so. Second, there is a very large volume of UFO testimony, with some events witnessed by literally thousands of people. Third, some of these people were expert witnesses civilian and military pilots, air traffic controllers, astronauts, astronomers, and other scientists. Finally, some of this testimony is corroborated by physical evidence, as in “radar/visual” cases. In short, the empirical evidence alone does not warrant rejecting the ETH. It does not warrant acceptance either, but this sets the bar too high.
