In Japanese manufacturing and construction industries, knowledge is often used not to solve problems, but to dominate conversations. This episode explores the phenomenon of “knowledge mounting” — people who flaunt expertise to assert superiority rather than create value. Drawing from real sales and on-site experiences, the podcast examines why this behavior emerges, how industry culture rewards complexity over clarity, and why loud confidence is often mistaken for competence. While acknowledging that technical knowledge is essential in these fields, the episode argues that true professionalism lies in sharing knowledge, not weaponizing it. Knowledge should connect people, not silence them.
