Not being in psychology, I don’t really know about type II errors, and I’d even agree that the majority of these UFO cases can be explained prosaically. But there are enough examples of bizarre unexplained cases out there, testified to by people of unquestioned professional disciplines, including members of the US military, that no thinking person can dismiss the possibility that the explanations for the phenomena are non ordinary, whether they attributed to alien intelligences, creatures from another dimension, or some other as yet unhypothesized reality. At least IMHO ;-)
RIGHT YOU ARE.
EVEN IF
there were only 1-5 cases that were unexplainable by conventional means and ‘science,’
THAT WOULD BE SUFFICIENT TO SIGNAL THAT THINGS WERE BEYOND VERY CURIOUS IN RIVER CITY.
THE MORE THAN 4,000 TRACE LANDING CASES ARE CONSIDERABLY MORE THAN 1-5 CASES.
And that doesn’t get into all the other VERY SOLID 100’s and thousands of other cases not involving trace landing evidence.
BTW, TYPE I & II errors are not only involved in psychology.
