Question

Quizplus · Accepted Answer

Les's behavior is exhibiting the sunk-cost fallacy, which refers to the tendency of individuals to continue investing time, money, or effort into something even if it may no longer be rational, simply because they have already invested in it. In this case, Les has already purchased the ginger beer, and therefore feels compelled to finish drinking it even though he is feeling full and his friend is warning him of potential negative consequences.
