Why the Markov blanket matters

A node's Markov blanket is its information boundary: the minimal set of variables that makes it conditionally independent of everything else in the network. Once you know the blanket, no further observation — however strongly correlated — can improve your prediction of the target node.

For prediction, the blanket defines the minimum sufficient feature set; adding variables outside it yields no lift regardless of sample size. For intervention design, it distinguishes direct levers (parents) from downstream effects (children) from indirect confounders (co-parents). For auditing, it reveals which variables must be controlled to isolate a causal effect. The blanket is also where fairness and privacy questions land: only variables inside it can causally influence the outcome.
