Schein observed across decades that culture identifies foreign elements and either integrates or rejects them, largely automatically, operating beneath conscious organizational decision-making.

The responses map onto biological immune patterns. Inflammation is the first and most visible: the organization heats up, conversations become charged, meetings produce disproportionate emotional intensity. The heat is diagnostic — it reveals which assumptions are being challenged and how deeply they are held. The senior partners at the consulting firm who reacted to AI tools with surprising intensity were not responding to
