They will try to predict your decisions and adjust their actions accordingly. Unlike inanimate objects such as a mountain, yogurt, or a path, which remain static regardless of your decisions, people can adapt. The introduction of other people generates a special type of uncertainty: strategic uncertainty.
Do you possess sufficient skill to ascend that mountain? Is the yogurt still edible? Does the alternative route truly offer a quicker path? Should you attempt to climb this mountain? Is it prudent to consume this yogurt just beyond its expiration date? Is it worth taking this apparent shortcut? In all these instances, the efficacy of your decision hinges on whether your beliefs align with reality. Uncertainty is a key feature of the world we live in and the circumstances under which we must make decisions.
