现状偏见背后的心理学已经通过几个不同的原则来解释，包括认知误解和心理承诺。以下解释是一些最常见的解释。重要的是，所有这些解释都被认为是偏好现状的非理性原因。研究表明，当个人做出决策时，他们比损失的可能性更大地衡量损失的可能性。因此，在考虑一系列选择时，他们更多地关注他们可能会因放弃现状而失去的东西而不是通过尝试新事物而获得的东西。沉没成本谬误指的是这样一个事实：个人通常会继续将资源（时间，金钱或努力）投入到特定的努力中，因为他们已经在这项努力中投入了资源，即使这种努力没有被证明是有益的。沉没成本导致个人继续沿着特定的行动方向，即使它失败了。沉没成本导致现状偏见，因为个人投资现状越多，他或她就越有可能继续投资于现状。

The psychology behind current bias has been explained by several different principles, including cognitive misunderstanding and psychological commitment. The following explanations are some of the most common explanations. Importantly, all of these explanations are considered to be irrational reasons for preferring the status quo. Studies have shown that when individuals make decisions, they measure the likelihood of loss more than the probability of loss. Therefore, when considering a range of choices, they pay more attention to what they might lose because they give up the status quo rather than what they get by trying new things. The cost of sunk costs refers to the fact that individuals often continue to invest resources (time, money or effort) into specific efforts because they have invested resources in this effort, even if such efforts are not proven to be benefit. The sunk cost causes the individual to continue along a particular direction of action, even if it fails. The sunk cost leads to a bias in the status quo, because the more individual investment is, the more likely he or she is to continue investing in the status quo.
