New protocols developed by Search for Extraterrestrial Intelligence (SETI) project and approved by the International Academy of Astronautics (IAA) now tighten significantly what the scientific community is expected to do if anyone detects evidence that might be extraterrestrial life.

You can read the full protocols here [pdf]. From the press release:

At the heart of the new rules is a reaffirmation of a core scientific principle: “extraordinary claims require extraordinary evidence.” Under the revised protocols, no public announcement should be made until a signal or artifact has been rigorously authenticated by independent organisations using different instrumentation.

“We do not shout “alien” the moment we see a strange blip,” Garrett added. “The scientific method demands we check, check again, and then ask others to check. Only when we have reached a consensus that a signal is credible do we bring it to the world.”

SETI’s press release notes this rule is necessary due to the modern nature of social media, which allows the wildest claims to be spread like poison almost immediately. As noted in this story, the new rules almost appear to be a direct slap at hack Harvard scientist Avi Loeb, who with both interstellar objects Oumuamua and Comet 3I/Atlas claimed evidence of alien technology when there was no evidence to say so.

The new rules also underline a second point: Under no condition will any scientist attempt to reply or contact any potential alien source. “The Declaration reaffirms the enduring principle that transmitting a response to an extraterrestrial intelligence is a decision that belongs to all of humanity and should only take place following international consultations, specifically through the United Nations.”

It will be impossible for the science community to enforce this rule, but by stating it they hope to encourage scientists to exercise more caution, and further ostracize those like Loeb who do not. I remain skeptical, especially because it will have no influence on government agencies like NASA, which love to scream “We have found alien biology!” at the slightest hint. Nor will it influence the public, which seems determined to accept such wild claims with no skepticism at all.
