The conventional belief that Thomas Edison solely discovered the lightbulb is a misconception. While Edison's patent focused on making the incandescent lightbulb practical and affordable, he built upon existing versions and collaborated with a team of skilled individuals. This highlights a broader tendency to attribute breakthroughs to lone geniuses, a narrative often perpetuated by popular media. However, research consistently shows that teams, rather than individuals, are the primary creators of new knowledge across most industries. New ideas require collaboration and teamwork to reach their full potential, and sustained success in any field stems from well-designed teams. This tendency to over-attribute success and failure to individuals, known as the fundamental attribution error, leads to flawed organizational structures that prioritize hiring "stars" over fostering effective teamwork. High-performing teams are not accidental but are intentionally designed with specific elements. These include appropriate composition with a diverse mix of skills, clear and vivid goals, well-designed tasks that offer autonomy and allow members to see progress, and supportive norms that encourage experimentation and idea sharing. Ultimately, the execution of great ideas and the creation of successful businesses rely more on the structure and capabilities of a team than on the brilliance of a single individual.
