After having received many requests to continue the story of detective Elijah Baley and his robot partner R. Daneel Olivaw, featured in his earlier novels The Caves of Steel and The Naked Sun, Asimov wrote this short detective story. After the story appeared, he received many letters from readers stating "Thanks, but we mean a novel".[1]
Baley is unexpectedly contacted by Daneel regarding a dispute between two reputable Spacers on board a ship, who have just submitted essentially identical papers about a revolutionary mathematical technique. Each claims they originated the idea, and approached the other for confirmation only to have them steal the concept and pass it off as their own. Neither will admit guilt and it would reflect badly on the ship's captain not to resolve the authorship prior to arrival at the planet where the papers are to be presented. Daneel suggests Baley, an unbiased outsider, to the desperate captain.
Both Spacers have personal robots, who happen to be the same model from the same production batch, and were privy to the discussion between the mathematicians in exactly the same way. The robots' accounts of the dispute are, like their masters' stories, mirror images of each other, apart from the fact that one robot must be telling the truth and one is lying to protect its master's reputation. Being Spacers, neither scientist will speak to an Earthman, but they do allow Baley to unofficially interview their personal robots via telepresence. Both robots respond identically to Baley's questioning, stating they would lie to protect a human's reputation, until he capitalizes on the single difference between the parties: one is elderly and towards the end of his distinguished career, while the other, though brilliant has yet to establish himself fully.
He puts to the younger mathematician's robot that his master could still rebuild his reputation, but the elder's would be completely overshadowed by an indiscretion in his old age. In contrast, he puts to the older mathematician's robot that his master's reputation would remain and speak for itself, but the younger's would be completely ruined by an indiscretion of his youth. The younger's robot switches his story to protect the elder man, while the elder's robot tries to maintain the elder is innocent, but ends up malfunctioning.
Baley has tried to convince both robots to change their stories. He thus surmises that the elder is the plagiarist, because if the younger's robot received no instruction to lie, it could easily switch sides; while if the elder's robot had been instructed to lie, but became convinced that it should now tell the truth, it could not easily countermand the order of its own volition when only a reputation and not a human life was at risk, and this has led to conflict and shutdown.
R. Daneel Olivaw visits his old friend Elijah Baley on Earth, requesting his assistance in resolving an issue on a Spacer ship. The vessel's passengers include two great Spacer mathematicians headed to a scientific conference on Aurora: the 270-year-old veteran Alfred Barr Humboldt, and the young (under 50) up-and-coming Gennao Sabbat. The two men are accusing each other of plagiarism.
Humboldt claims that prior to boarding the ship, he devised a revolutionary mathematical technique for neural analysis, and discussed the matter with Sabbat while abroad. The younger mathematician was strongly supportive of the idea, and Humboldt wrote a paper on the subject to be presented at the conference, only to discover that Sabbat had done the same in an attempt to falsely claim credit. Sabbat's story is identical, except for the "mirror image" of names: in this version, it was he who created the technique and Humboldt who tried to appropriate it. Each of the men has a personal robot, of identical model and production year, testifying in its master's support.
Neither mathematician will confess to the crime (and there is no guarantee that a confession would result in justice, in any case) or accept a psychic probe, and no documentary evidence is available to resolve the issue. Failure to resolve the dispute before the ship reaches Aurora would result in an undesirable public scandal. Daneel persuaded the captain to take a detour to Earth and obtain the assistance of Baley, avoiding unnecessary publicity.
Neither mathematician will consent to an interview by an Earthman or an inspection of his robot by an Earth robopsychologist, so Baley remotely interviews the two robots in sequence. Each acknowledges that it would lie to protect its master's reputation, to prevent harm under the First Law of Robotics, although whether its master's reputation or that of another person is more important would have to be decided on a case-by-case basis.
To Sabbat's robot, Baley explains that it would be more important to protect Humboldt's reputation than Sabbat's: the latter's offences could be explained away as the errors of a hot-blooded youth and he has a long career ahead of him to recover his reputation, while Humboldt's great historic achievements would be forgotten in the wake of his one crime and he would have little lifespan left to make up for it. To Humboldt's robot, he takes the opposite position: Humboldt's past reputation would shield him from the worst consequences, and he would be excused as an old man no longer sound in judgement; the less secure Sabbat would have a future great career, spanning hundreds of years, closed off by a single mistake of youth.
Sabbat's robot accepts the explanation and confesses to its master's act of plagiarism, while Humboldt's malfunctions and shuts down. Baley interprets their differing reactions as follows: the liar's robot would have been ordered strongly to lie, thereby combining First Law and Second Law, while the truth-teller's robot would receive no such orders (as it could be trusted to support its master on its own) and its actions would be governed only by First Law. Thus, the truthful robot could be persuaded to switch to a lie without too much trouble, while the lying robot would risk breakdown of its positronic circuits in switching to the truth. Baley concludes that Humboldt's robot was the one originally lying.
Presented with the results of the interview, Humboldt breaks down and confesses to the plagiarism. Afterwards, Daneel asks why Baley selected that interpretation, as it could just as easily be argued that it would be easier for a robot to switch from lying to telling the truth than the reverse. Baley explains that he already guessed that Humboldt was the guilty one based on his knowledge of human behavior, and simply interpreted the robots' behavior as evidence against his chosen suspect to intimidate him into a confession. According to Baley, a young academic like Sabbat would be interested in discussing his new idea with a senior peer and would not dare plagiarize such a "revered demigod" in the field, while a senior figure like Humboldt would not think to consult a junior and might well be willing to take advantage of such a newcomer for one last career triumph.
Isaac Asimov, a visionary in the realm of science fiction, unknowingly pioneered modern prompt engineering through his thought-provoking exploration of human-robot interactions in his groundbreaking Robot Series.
Prompt engineering is a process in which input prompts to an AI large language model are crafted and refined to generate accurate, relevant, and useful output. It involves deliberate and systematic design and refinement of prompts and underlying data structures to manipulate AI systems towards achieving specific and desired outputs. With the emergence of AI, particularly natural language processing models, prompt engineering has gained significance as a means to improve the effectiveness and user experience of AI systems.
One, Zero or Few shot prompting: Providing zero, one or a few examples of question/answers to help set the context for the AI and constrain it along a specific path and get more accurate results.
Spacer worlds, in contrast, are technologically advanced societies with a sparse population, where humans and robots coexist in harmony, and robots have become an essential part of everyday life. The Spacer worlds maintain a condescending attitude towards Earth and its inhabitants, seeing them as backward and inferior.
Throughout Asimov's stories, the interactions between humans and robots, as well as the ethical and philosophical implications of the Three Laws, form the backbone of the Robot universe, offering readers a unique exploration of the challenges and potential consequences of a future where humanity and advanced artificial intelligence coexist.
Isaac Asimov's Robot series and short stories, starting from the 1950s, put a strong emphasis on the importance of giving precise commands to robots, which can be seen as a precursor to modern prompt engineering. Asimov's works demonstrated an inherent understanding of the need for carefully crafted instructions, particularly when dealing with complex AI systems implied in his robots operating under the Three Laws of Robotics.
During a casual interstellar trip by a group of spacers a crime happens on the spaceship. The two parties are a young and brilliant mathematician (Sabbat) and and elder and established mathematician (Humboldt), both are accusing the other of stealing a brilliant new mathematical idea from the other. The only witnesses are each mathematicians robot servants. The earthman detective Elijah Baley is asked to help investigate and solve the crime as soon as possible before it explodes into a much bigger scandal, however all he's allowed to do is interview the robots. Baley sees that each party is putting forward the mirror image of the other partys story, and he has to figure out which party is lying.
Detective Baley interrogates the younger mathematicians (Sabbats) robot and walks it through the logical steps that shows that the elder mathematician would come to greater harm through the robots testimony and gets the robot to change its testimony.
