…continuing to dishonestly redefine terms in unconventional ways in order to support the belief in aliens is contrary to science and skepticism.
Let’s examine that assertion for critical thinking shall we?
First, here are the principle reasons why some people might believe the extraterrestrial hypothesis (ETH) is plausible explanatory hypothesis.
First we have the observational evidence of ostensible 'nuts and bolts' craft, intelligent manoeuvring and associated beings.
Then we have the multiple eyewitness, radar, film and photographic and physical trace evidence.
Then we add in the lack of plausible mundane explanations for that evidence and couple it with the fact that there is nothing in science that would preclude ET visitation.
The ET hypothesis is then a plausible explanatory hypothesis.
That of course
does not mean it is
the explanation for UFOs (meaning ‘genuine UFOs’ or those that after much analysis and research have no plausible mundane explanation) – it merely means that there is evidence to support a belief in the ET hypothesis.
How does any of that then “
dishonestly redefine terms in unconventional ways”? Of course it does not.
How is any of that “
contrary to science and skepticism.”? Of course it is not.
If it is not actually contrary to science and scepticism and draws on existing evidence to allow the formation of plausible hypotheses – then it is not pseudoscientific.
Consider also the following:
The methods used in UFOlogy by its practitioners who believe that UFOs are alien spaceships is pseudoscience because UFOs as alien spaceships has never been shown to be the answer.
Interestingly science is often about gaining knowledge about things where we do not know the answer. For things about which science has no answer hypotheses are formed and then they are explored to determine if they have any evidential support. Just because a particular hypothesis has not been “proved” (beyond a reasonable doubt) does not mean that the existing evidence cannot be used to shape our beliefs and guide us in further enquiry. Progress in science would simply stall if we required absolute proof of every hypothesis ever proposed before we proceeded to explore the implications.
The ET hypothesis is a hypothesis where there is circumstantial evidence in support. It is not in the least pseudoscientific to form opinion based on that evidence and then proceed to explore the ramifications of those opinions.
One can even form null hypotheses to test various assumptions and beliefs surrounding the ETH. For example:
If the UFO debunkers are correct and all UFO reports principally arise from a misidentification of mundane objects, then there should be no difference between defined characteristics (speed, shape, et) between those reports that have bee shown to have plausible mundane explanations and those that have not.
That is a falsifyable null hypothesis that would test a principle belief of the UFO debunkers – one that they use against the ET hypothesis all the time.
It seems however the UFO debunkers fear the outcome of such a scientific test – for they never say, ‘I have confidence in my belief that UFO reports principally arise from a misidentification of mundane objects, so okay, go ahead and test the hypothesis and we would be interested in the results when you have done so’.
Instead they come out with all sorts of objections – for example ‘We also believe hoaxes and delusions result in UFO reports – so the hypothesis is invalid’. However this objection does not recognise two critical points: First, that “hoaxes and delusions” should also be similarly spread between the two groups, so they will have no statistical bearing on the outcome of any analysis and Second, that a number of studies have shown that the incidence of hoaxes and delusions is actually insignificant (between 1-2%) so if, in testing the hypothesis, we obtain a statistically significant difference, we can also say that “hoaxes and delusions” have not have made a significant contribution.
There is a scientific test. It is not pseudoscience.
