The confirmation error and sunk-cost fallacy are related concepts, but they are not the same thing. The confirmation error refers to the tendency to search for, interpret, and remember information in a way that confirms preexisting beliefs, while the sunk-cost fallacy refers to the tendency to continue investing in a course of action because of sunk costs that have already been incurred, even if that course of action is no longer beneficial or rational.
