The scholarly paper "Would Contact with Extraterrestrials Benefit or Harm Humanity? A Scenario Analysis" by Baum, Haqq-Misra, and Domagal-Goldman offers a methodological exploration of various possible extraterrestrial intelligence (ETI) contact scenarios. This work synthesizes a comprehensive spectrum of potential outcomes that humanity might face upon contact with ETI, framing them in terms of benefits, neutrality, and harms. This paper's contributions lie in its systematic approach to scenario analysis, which aids in forming a structured understanding of potential interstellar interactions.
The absence of physical evidence of extraterrestrial presence underscores the necessity of considering a range of theoretical scenarios. The authors categorize potential contact outcomes into three core classifications—those that are beneficial, neutral, or harmful to humanity—with further distinctions within each category to accommodate various sub-scenarios.
Beneficial Scenarios
Contact that enhances human civilization is explored under the assumption of either mere detection or beneficial interaction having occurred. Detection alone could provide philosophical and scientific validation of the existence of other intelligences, potentially reshaping worldviews and scientific paradigms. Meanwhile, cooperative interactions might yield significant technological, ethical, or intellectual exchanges. Particularly, advanced ETI could theoretically offer solutions to global issues such as energy scarcity or technological catastrophes, contingent on their willingness to assist us. This exploration does not discount the extrapolation of knowledge about the ecology and long-term sustainability from ETIs believed to practice non-violent, sustainable expansion.
Neutral Scenarios
For the contact to be neutral in impact, several conditions must apply: either ETI remain undetected, or the impact must counterbalance any benefits of detection. The invisibility of ETI can be intentional, such as the Zoo Hypothesis posits, or unintentional, due to differences in communication methods or sheer interstellar distances. Alternatively, ETI might detect human existence but perceive no compelling reason to respond or intervene. The recognition of such scenarios is vital due to their likelihood of non-disruption of current human paradigms, while still keeping open the door for potential, albeit minimal, effects on human society.
Harmful Scenarios
A significant focus within this paper is given to scenarios positing the potential for harmful interactions. Intentional harm could result from hostile ETI with motives of conquest or resource acquisition. More nuanced is the possibility of 'benevolent' ETI causing harm due to universalist intents perceived as a threat to human survival if humans are deemed an impediment to galactic equilibrium. Interestingly, even inadvertent harm could transpire through biological contamination or detrimental technological trials resembling earth-bound analogs. Unintentional destruction through mechanical accidents or cultural dominance is also considered a plausible outcome.
Implications and Considerations
This scenario analysis implies prudence in any efforts such as Messaging to Extraterrestrial Intelligence (METI) by advocating for a cautious approach to interstellar communication. Precautionary measures should aim to conceal specific anthropogenic activities that might provoke a defensive or exploitative response from ETI civilizations. Furthermore, scenario analysis iterates the importance of global preparedness and integration in contemplating the vast domain of potential ETI interactions, ensuring adaptive strategies that accommodate diverse outcomes, whether foreseeable or speculative.
This paper sets the stage for more empirical, quantifiable research on the subject. While precise probabilities of each scenario remain unquantified, they pave the way for further interdisciplinary investigation integrating astrobiology, cosmology, and ethical considerations, striving toward a coherent understanding of our possible extraterrestrial futures. Such explorations emphasize the urgency of aligning policies with environmental preservation not just for terrestrial benefits but also as a prudent strategic maneuver on the interstellar stage.
