“Confirmation of extraterrestrial intelligence would cause severe psychological destabilization in human populations prior to any physical contact.”

Taken together, this work strongly suggests that if we do discover life of non-earthly origin, on the whole, human beings and human societies are likely to respond positively. We found that people’s forecasts of their own reactions showed a greater positivity bias than their forecasts of humanity’s reactions, and responses to reading an actual announcement of the discovery of extraterrestrial microbial life showed more positive vs. negative affect.

Jung further suggested that UFOs might symbolize unknown or alien forces within the human psyche... Claims of their existence were due to stressors including Cold and Thermo-nuclear War anxiety, hysteria and additional social tensions... The role of Jung's theories suggests that humanity may project certain unconscious and conscious desires or fears onto the awareness of ETI civilizations, which could ruin potential constructive interactions with ETIs.

The UAP psychological effect on witnesses and also in interested people was clearly transformative... UAP pushes these processes to their limits, to unknown territories, creating cognitive dissonance in witnesses... This effect can be referred to as ‘transformative’ but specifically focused on the phenomenon itself, since it does not necessarily change other aspects of the daily life of the witness.

Research published in Frontiers in Psychology investigates humanity's hypothetical reaction to the discovery of extraterrestrial microbial life. Participants’ responses also showed significantly more positive than negative emotions, both when contemplating their own reactions and those of humanity as a whole. Varnum said the studies show that 'taken together, this suggests if we find out we’re not alone, we’ll take the news rather well.'

The active SETI opponents invoke what might be thought of as a 'War of the Worlds' argument — basically, do we really want to let potentially unfriendly and dangerous aliens know that we're here? But Vakoch and other supporters of active SETI say the 'hostile aliens' argument is moot.

We also draw attention to the possible positive and negative consequences for humans of an encounter with ETIs so understood... This need not be a cause for existential worry, although as long as we are unable to free ourselves from the anthropomorphic bias in thinking about the evolution of morality, we have reason to fear ETI equating moral status with intelligence.

In addition, we asked participants to evaluate several psychological components which we believe are related to extraterrestrial beliefs. These were anthropocentrism, curiosity, comfortable with ambiguity, skepticism, existential anxiety, institutional trust, science-fiction consumption, UFO/UAP (Unidentified Flying Objects or Unidentified Anomalous Phenomena) content exposure, and social media use.

Results of the Pilot Study suggest that reactions to past announcements of extraterrestrial life discovery (or evidence that suggests such life may exist) are largely positive, indicating greater positive vs. negative affect and more emphasis on potential rewards vs. risks. To the extent that media coverage reflects the broader cultural mood, these findings suggest that society is likely to react in a positive fashion if we were to discover extraterrestrial life in the future.

Limits to civilization lifetimes may explain why extraterrestrial aliens have not yet communicated with Earthlings. A lack of signals from space may also be bad news for Earthlings.

Surprisingly, much of the preparation work focuses not on alien technology but on human psychology and interaction. The researchers emphasise integrating humanities and social sciences, recognising that the biggest challenges might come from how people react to the news rather than from the aliens themselves. The paper recommends funding research on the psychological, social, and global dynamics of post detection scenarios.

The paper offers the view that first contact with alien life poses considerable risks for humanity. Additionally, a first contact event could also take place without being culturally recognized. Humans do not respond well to “otherness.” We are frightened and divide ourselves into “us” versus “them.”

About two-thirds of Americans (65%) say their best guess is that intelligent life exists on other planets, according to a Pew Research Center survey conducted just before the release of the government assessment. A smaller but still sizable share of the public (51%) says that UFOs reported by people in the military are likely evidence of intelligent life outside Earth.

In a separate study, the team asked more than 500 different participants to write about their own hypothetical reactions and humanity’s hypothetical reaction to an announcement that extraterrestrial microbial life had been discovered. Participants’ responses also showed significantly more positive than negative emotions, both when contemplating their own reactions and those of humanity as a whole.

Results revealed a graduated consensus pattern: 86.60% of astrobiologists agreed basic extraterrestrial life likely exists, 67.40% agreed regarding complex life, and 58.20% agreed that intelligent life likely exists somewhere in the Universe. Participants exhibited massive pluralistic ignorance, a 'cosmic closet', underestimating social circle beliefs by 46.07 percentage points despite near-universal personal conviction.

Researchers are looking into the potential psychological impacts of such an announcement, which some people might have a hard time accepting. That knowledge would likely have far-reaching effects on our view of ourselves and our place in the universe.

A few reactions would probably be irrationally extreme or even violent. Education is identified as a factor that correlates with positive attitudes toward SETI. To the extent that such analogies are applicable, they suggest more of a gradual change in world view than a dramatic upset in the day-to-day conduct of society.

The mind does not do well under prolonged conditions of uncertainty and confusion. ... To satisfy our curiosity and control anxiety we are likely to draw on preconceptions, expectations, attitudes and prejudices, and then seek validation from like-minded others. Looking to 'inner space' is likely to be as important as turning our gaze to outer space, and problems that result will be largely of our own making.

NASA's 1992 'Post-Detection Scientific Protocol' outlines guidelines for responding to signals from extraterrestrial intelligence, emphasizing scientific verification and international coordination without anticipating societal panic. It assumes disclosure can be managed through transparent communication, drawing from historical precedents like the 1996 ALH84001 Mars meteorite announcement, which caused public interest but no widespread destabilization.
