👉 The correlation weapon is a concept from game theory and economics that describes a situation where two or more parties, often in competitive environments, can achieve disproportionate gains by aligning their strategies based on shared information or correlated actions. Essentially, it's when the outcome for each participant depends not only on their own decisions but also on the decisions of others, creating a kind of "correlation" that can lead to unexpectedly favorable results. For example, in financial markets, if two firms decide to raise prices simultaneously based on correlated market signals, they might both benefit from increased revenue without engaging in a costly price war. This weapon arises when coordination, even if unintentional, can lead to better outcomes than independent actions.
