Questions
What is Containment?
Containment means limiting a problem's ability to spread before trying to destroy it, like a firebreak around a wildfire. George Kennan's Cold War strategy aimed to stop Soviet expansion rather than fight directly, and Johnson & Johnson's 1982 Tylenol recall contained a crisis and kept public trust.
How do you use Containment?
When trouble hits, first isolate it so it can't spill into the rest of your work or life. Map the ways it could worsen and block those paths. Focus resources on the boundaries before tackling the root cause, then solve the core problem once it can no longer spread.
When does Containment matter?
Containment is one of the 40 mental models for fixing problems, the situations where you ask: Why does this keep going wrong, and how do I fix it for good? Within that, it belongs to “How problems spread”, alongside Broken Windows Theory, Chain Reaction and Critical Mass.
What is an example of Containment?
Two stories show it at work: Kennan’s long game (1946–1947) and Johnson & Johnson (1982). Both are told in full in The Mental Models Daily Almanac, which has two stories for each of its 365 models.
Which mental models are related to Containment?
Stop the Bleeding, De-Risking and Deterrence. Containment itself comes from military and war.
