A captain who says “that’s on me” in the huddle gets a team that stops pointing fingers.

What a leader does after a mistake sets the price everybody else pays for admitting one. If the person at the front takes theirs openly, the cost drops for the whole group, and people start naming their own errors because it is clearly survivable. If blame travels outward instead, everyone learns to aim it somewhere else quickly.

If you have any kind of leading role, take yours out loud the next time something goes wrong, early and without performance. Then watch how the next person speaks. You are setting what honesty costs around here.
