Mental Models That Actually Work: 40 Thinking Tools, Evidence-Checked

Mental Models That Actually Work by Ada Fenwick covers forty thinking tools used by investors, engineers, scientists and forecasters. Each tool is traced to its source and checked against the research. An evidence badge marks it SOLID, PROMISING or STORY ONLY. Topics include first principles, inversion, the outside view, calibration and the pre-mortem. The book also flags famous quotes that turn out to have no record.
