因此，不管有任何相反的证据，简单地为自己的信仰提供解释的行为可能会使它变得更加根深蒂固。 这是因为，即使有人被告知有证据证明某人相信某项信仰，但他们提出解释该信仰并没有被抹黑的所有理由。 心理因素也有助于解释信念的恒心。 导致信念坚持不懈的一个过程是可用性启发式方法，人们使用该方法来确定事件或行为的可能性是基于他们对过去示例的理解程度。 因此，如果有人否定自己在工作中成功发表演讲的能力，那可能是因为他们只能想起过去所做的失败演讲。 但是，请务必记住，通过可用性启发法对个人进行的评估是主观的，并且要基于他们过去的演讲对他们的记忆力。
Therefore, regardless of any evidence to the contrary, simply providing an explanation for your beliefs may make it more ingrained. This is because even if someone is told that there is evidence that someone believes in a belief, they all reason to explain that the belief has not been smeared. Psychological factors also help explain the perseverance of beliefs. One process that leads to perseverance is the usability heuristic approach, and the likelihood that people use it to determine events or behaviors is based on their understanding of past examples. Therefore, if someone denies their ability to speak successfully at work, it may be because they can only remember the failed speeches made in the past. However, it is important to remember that the assessment of individuals through usability heuristics is subjective and based on the memory of their past speeches.
