Everyone on the team brings to the table a unique configuration of experience, knowledge, abilities, connections, ideas and questions. It is an irrelevant comparison to make about whether one person or another smarter than everyone else when in fact when a team is aligned people are smarter together. This implies smarter than any individual boss might be or strive to be.
This has practical everyday implications. When we rely on the collective intelligence of the group we listen better and collaborate more frequently and effectively. We grow more together.
