Context & Analysis

The book is the fourth in the "ChatGPT for Doctors by Doctors" series, which Igaku-Shoin says has passed 100,000 cumulative copies. Where the earlier volumes focused on clinical use and prompt techniques, this one steps back: its title character "0" means both readable from zero knowledge and aiming to close the psychological distance to AI.

The author, Dr. Atsushi Otsuka, grounds the book in an anecdote from a local medical association lecture, where an internist with over 30 years in practice shouted that using such tools would stop young doctors from developing. Otsuka writes that the doctor was not behind the times but had something worth protecting, and frames physicians' hesitancy as a natural instinct to safeguard patients.

Each chapter pairs that reframing with practical sections, and the book weaves in behavioral-economics concepts such as status quo bias, loss aversion and the anchoring effect. The stated aim is to help newcomers take a safe first step while giving existing readers fresh perspective.
