人类对亡灵和来世的认知方式比我们自己意识到的要复杂得多。奥塔哥大学的来世信念实验室研究发现，即使人们不相信鬼魂存在，被告知房间里有幽灵后，也会表现出更大的生理压力反应[1]。这项研究的目标并非证明或反驳天堂地狱的存在，而是探索生者如何思考死者的思维[1]。研究表明，无论儿童还是成人，都倾向于认为抽象的思想和感情会在死后存活，而身体机能则会消亡[1]。
研究人员发现了一个有趣的现象——相信死者在监视可以促进合作行为[1]。在实验中，当研究人员告知参与者房间里有幽灵出现时，那里的参与者较少在金钱任务中作弊，这体现了"超自然惩罚假说"的作用[1]。皮克斯电影《寻梦环游记》描绘的设定为"直到没有活人记得你的名字，你才会经历'最后的死亡'"，反映了这一心理认知[1]。
随着人工智能技术的进步，这些既有的心理偏见被进一步放大了。所谓"数字悼念"现象已经出现——人们开始将已故亲属的信息输入AI，以继续与他们对话[1]。曾经在2013年《黑镜》剧集《Be Right Back》中描绘的科幻场景，如今已成为现实[1]。
Humans have long held peculiar beliefs about what happens after death, and emerging artificial intelligence technologies are now intensifying these psychological tendencies. Research from the University of Otago's Afterlife Beliefs Lab examines how people conceptualize the minds of the deceased, revealing fundamental patterns in human cognition that AI is now beginning to exploit.[1]
The Otago research is not designed to prove or disprove the existence of heaven or hell, but rather to investigate how the living think about the minds of the dead.[1] Studies show that even people who consciously reject belief in ghosts display measurable physiological stress responses when told a room is haunted.[1] Both children and adults tend to assume that abstract thoughts and emotions survive death while bodily functions do not.[1] This cognitive pattern extends to behavior: a phenomenon researchers call the "supernatural punishment hypothesis" suggests that believing the deceased are watching promotes cooperative conduct—in studies, participants were less likely to cheat on financial tasks in rooms where they had been told ghosts were present.[1]
The emergence of "digital mourning" has brought this psychological predisposition into the technological realm.[1] People are now inputting information about deceased relatives into artificial intelligence systems to continue conversations with them, transforming what was once confined to imagination or spiritual practice into interactive digital experiences.[1] This development echoes a 2013 Black Mirror episode, "Be Right Back," which depicted this scenario as speculative fiction—a concept that has since become reality.[1]
