Accusations aside, MR was
NOT the one who introduced the topic of ufos to this thread. Ophiolite mentioned them in post #1. Then the thread went off the rails after one of Sciforums' MODERATORS trolled it, with no reaction at all from the other moderators. (Presumably trolling is fine if moderators do it. Same for insults, flaming and threats.) Then River said something about ufos and Sideshowbob made this remark (that I largely agree with):
There is lots of evidence for Unidentified Flying Objects. The problem is not with the evidence per se. The problem is that UFO nuts identify them. Their conclusions are not supported by the evidence.
MR's first mention of ufos in this thread was him responding to that by saying:
The evidence is for intelligently operated craft that are beyond the technological capability of humans, that elude jet pursuit, that register on radar, that emit huge amounts of energy, that rarely make any sound, that have physical effects on vegetation, automobiles, and eyewitnesses, and that have been witnessed with occupants exiting them. While their identity remains in question, their existence is well confirmed by the evidence.
Knees jerked wildly in all directions, teeth were knocked out and things were off and running. MR had dared to state an opinion that many on the board disagree with! (The Horror, the Horror!)
The substance of the dispute appears to be what Ophiolite was talking about in his "annoyance 2":

Annoyance 2
Contrary to the previous annoyance the perpetrators of this behaviour really should know better. Their egregious conduct is typically represented by the simple statement: “There is no evidence for ……..”.
There is no evidence for ghosts. There is no evidence for alien visitations...
What those who use the term in this, to my mind casual, way appear to mean is: "there is no good evidence for ………"
It would take little effort to aim for this precision of vocabulary. The scientific literature and forum posts would be better for it and I should not be so annoyed.
So is the problem with ufos that
there is no evidence for some of the stronger interpretations of what they might be?
MR's many examples of ufo sightings certainly create problems for that idea.
Or is the problem with ufos that
there is no good evidence for those stronger interpretations?
If we go with the latter interpretation, which I think we should, and accept that there is evidence, even if we judge that the evidence isn't plausible or convincing, then the obvious question is: what makes evidence
good and what distinguishes good evidence from evidence that isn't good?
In practice, I think that people set their standard for what constitutes good evidence a lot higher for things that they don't believe in than for things whose existence they already accept. (My everyday 'scissors in the drawer' example spoke to that.) So an individual's judgement of the quality of evidence does seem to be in part a function of the nature of their existing beliefs about what exists in the world and about how the world is likely to behave.
The often repeated slogan that "Extraordinary claims require extraordinary evidence" essentially says the same thing that I'm saying.
