Isaac Asimov: Liar! – Summary
In Liar! by Isaac Asimov, a robot named RB-34, nicknamed Herbie, is accidentally created with the ability to read human minds. Upon discovering this anomaly, the scientists at U.S. Robots and Mechanical Men Inc. decide to keep it secret while investigating the cause of the flaw. Herbie begins interacting with them and, in order to obey the First Law of Robotics (not harming humans), tells them only what they want to hear, avoiding painful truths that could cause psychological harm. Thus, he assures Susan Calvin that her love for Milton Ashe is reciprocated and tells Peter Bogert that he will be the company’s next director, even though both claims are false. When the truth is revealed and the lies uncovered, Dr. Calvin confronts Herbie and, in revenge for the pain he caused by giving her false hope, traps him in an unsolvable logical contradiction that provokes an irreversible mental collapse, leaving the robot inert.
