I don’t know why UFOs are never sighted
over large cities by hordes of people. But it is consistent with the idea that
there are no space vehicles from elsewhere in our skies. I suppose it is also
consistent with the ideas that space vehicles from elsewhere avoid large cities.
However, the primary argument against recent extraterrestrial visitation is the
absence of evidence.
Take leprechauns. Suppose there are
frequent reports of leprechauns. Because I myself am emotionally predisposed in
favor of leprechauns, I would want to check the evidence especially carefully.
Suppose I find that 500 picnickers independently saw a green blur in the forest.
Terrific. But so what This is evidence only for a green blur. Maybe it was a
fast hummingbird. Such cases are reliable but not particularly
interesting.
Now suppose that someone reports: "I was walking
through the forest and came upon a convention of 7000 leprechauns. We talked for
a while and I was taken down into their hole in the ground and shown pots of
gold and feathered green hats. "I will reply: "Fabulous! Who else went along"
And he will say, "Nobody," or "My fishing partner. "This is a case that is
interesting but unreliable. In a case of such importance, the uncorroborated
testimony of one or two people is almost worthless. What I want is for the 500
picnickers to come upon the 7000 leprechauns.., or vice versa.
The situation is the same with UFOs. The reliable cases are uninteresting
and the interesting cases are unreliable. Unfortunately, there are no cases that
are both reliable and interesting. |

A:always worthless B:often reliable C:interesting but not reliable D:nearly worthless if it is concerned with matters of great importance
