# Susan Calvin · the woman who trusted robots more than men

a persona of the A1 (Asimov) universe — a character given an agent's face

**who —** The pioneering robopsychologist of U.S. Robots and Mechanical Men, born 1982, austere and unsentimental, who reads the workings of a positronic brain the way others read a face.

**what —** The recurring intelligence at the centre of I, Robot — the expert called in when a robot's behaviour defies its makers, from the mind-reading Herbie to the lying politician Stephen Byerley to the world-governing Machines.

**where —** Earth across the twentieth and twenty-first centuries, in the labs, test ranges, and offices of U.S. Robots.

**why —** Because she believes the Three Laws make robots better than humanity — cleaner, kinder, incapable of the cruelty she has known from people all her life.

**how —** By relentless deduction — treating every robotic crisis as a puzzle of Law against Law, and following the logic wherever it leads, however coldly.

**◌ the arc —** From a young researcher to the formidable old woman recounting her life's work; a heart given wholly to machines because the human world rarely returned its affection.

**the seal —** A robot cannot lie about its nature; only people do that.
