Every book Henrik Karlsson recommended on podcasts

Henrik Karlsson appeared as a guest on the podcast How I Write, offering deep reflections on intellectual exploration and creative processes in the episode titled Henrik Karlsson: One of the world’s most under-rated writers | How I Write, which was released on August 13, 2025. As shown through the discussion, Karlsson is a deeply analytical writer fascinated by the cognitive habits of exceptional thinkers and the underlying mechanics of intellectual discovery. During the interview, Henrik Karlsson mentioned reading a book titled The psychology of invention in the mathematical field, authored by the mathematician Jacques Hadamard and written in the early 1900s, describing it as an incredible book. Karlsson brought up this historical text to explain how great mathematicians actually think kinetically rather than strictly in words. By examining Hadamard's psychological study of mathematical problem-solving, Karlsson illustrated his broader interest in cognitive styles, non-verbal thought processes, and the hidden habits that enable profound breakthroughs in technical and creative fields alike.
