The Culture People Actually Describe
The real measure of a culture is how the people inside it describe it when they are being honest, and how those who left describe it once there is nothing to lose by being candid. That description, not the values statement, is the culture.
Kevin builds the hour toward closing the gap between the two, because a sceptical room respects honesty about its own culture far more than another round of aspirational language. The point is to see the culture clearly, not to feel good about it for an afternoon.
For an organiser, a room that leaves thinking honestly about what its culture actually rewards, rather than moved by talk of purpose, is the result worth the slot, and the one a market allergic to corporate sentiment will respect.
