论文摘要
随着我们对外星智力（SETI）进行更强大的搜索能力的增长，对消息传递外星智能（METI）的更具争议性的努力的兴趣也会增强。元人的支持者指出了SETI悖论 - 如果所有文明都避免了Meti，那么Seti是徒劳的。我将相互可检测性作为一种游戏理论策略，旨在提高目标SETI的成功潜力。相互可检测性由四个定律体现：相互性，对称性，机会和优越性。这些法律确定了SETI参与者如何使用应用于相互存在的相互证据的游戏理论原则相互参与。优越定律建立了对党派的“责任”，两者都可以判断出有更好的质量证据或共同点信息（CDI），从而避免了SETI悖论。我认为，地球运输区域内的过渡系外行星形成了满足相互可检测性要求的目标子集。我将固有的时间集成信号强度确定为合适的CDI。关于半径宜居行星的文明$ r _ {\ rm p}/r _ {\ oplus} \ sillssim（l _*/l _*/l _ {\ odot}）^{ - 1/7} $具有优越的CDI，因此具有游戏性奖励（Onus）来传输。尽管这意味着向我们介绍$ l_*> l _ {\ odot} $恒星的责任落在我们身上，但考虑相对恒星频率，主序列的生命周期和行星的考虑意味着这种系统可能是少数少数。对地球 - 拟南芥的地球交通区域的调查在亚极性光度宿主周围转运，然后对其进行针对性的SETI监测，代表了一种有效的策略，符合相互可检测性的有效策略。在这种情况下，选择保持沉默的选择并不是在这种情况下引起SETI悖论的关注。
As our ability to undertake more powerful Searches for Extraterrestrial Intelligence (SETI) grows, so does interest in the more controversial endeavour of Messaging Extraterrestrial Intelligence (METI). METI proponents point to the SETI Paradox - if all civilisations refrain from METI then SETI is futile. I introduce Mutual Detectability as a game-theoretic strategy aimed at increasing the success potential of targeted SETI. Mutual detectability is embodied by four laws: mutuality, symmetry, opportunity and superiority. These laws establish how SETI participants can engage each other using game theory principles applied to mutual evidence of mutual existence. The law of superiority establishes an "onus to transmit" on the party whom both SETI participants can judge to have better quality evidence, or common denominator information (CDI), thus avoiding the SETI Paradox. I argue that transiting exoplanets within the Earth Transit Zone form a target subset that satisfies mutual detectability requirements. I identify the intrinsic time-integrated transit signal strength as suitable CDI. Civilisations on habitable-zone planets of radius $R_{\rm p}/R_{\oplus} \lesssim (L_*/L_{\odot})^{-1/7}$ have superior CDI on us, so have game-theory incentive (onus) to transmit. Whilst this implies that the onus to transmit falls on us for habitable planets around $L_* > L_{\odot}$ stars, considerations of relative stellar frequency, main-sequence lifetime and planet occurrence mean such systems are likely a small minority. Surveys of the Earth Transit Zone for Earth-analogue transits around sub-solar luminosity hosts, followed up by targeted SETI monitoring of them, represent an efficient strategy compliant with mutual detectability. A choice to remain silent, by not engaging in METI towards such systems, does not in this case fuel concerns of a SETI Paradox.
