We've all been hearing about this for years with varying degrees of belief. I read an article some time mid-May that said the US govt is required to disclose all its information by June 1st, so I expected it to be open season after that date. I figured whatever came out would suck up all the oxygen in the room for a month. I must have misunderstood, because no such release of documents is being breathlessly discussed.
Michael Shermer of Skeptic magazine has a Quillette article Understanding the Unidentified that was interesting. I have never been convinced that Extraterrestrial Intelligence has been detected in any way. I am neutral on whether it has ever existed anywhere, but strongly negative that it has manifested on earth. Shermer makes the interesting point that increasing numbers of unexplained incidents without anything definite actually decreases the probability that these are aliens. Also
In a 2017 article in the journal Motivation and Emotion entitled “We Are Not Alone,” the psychologist Clay Routledge and his colleagues found an inverse relationship between religiosity and ETI beliefs—that is, those who report low levels of religious belief but high desire for meaning show greater belief in ETIs. In Study 1, subjects who read an essay “arguing that human life is ultimately meaningless and cosmically insignificant” were statistically significantly more likely to believe in ETIs than those who read an essay on the “limitations of computers.” In Study 2, subjects who self-identified as either atheist or agnostic were statistically significantly more likely to report believing in ETIs than those who reported being religious (primarily Christian). In Studies 3 and 4, subjects completed a religiosity scale, a meaning in life scale, a well-being scale, an ETI belief scale, and a religious supernatural belief scale. “Lower presence of meaning and higher search for meaning were associated with greater belief in ETI,” the researchers reported, but ETI beliefs showed no correlation with supernatural beliefs or well-being beliefs.
