这是我注意到自己身上的一种现象，我很好奇它背后的机制是什么。每当我收到看起来很正式的信件或电子邮件——来自银行、政府部门、学校等——我几乎立刻就会感到一阵焦虑。奇怪的是，这种反应发生在我甚至还不知道邮件内容是什么之前。在大多数情况下，邮件内容最终都是例行公事或无害的。尽管如此，焦虑的反应总是先出现，有时会持续到我完全理解邮件内容为止。我不是在寻求个人建议，但我很好奇这种反应是否与人类处理权威、不确定性或感知到的后果的方式有关。对于为什么仅仅是这种预期就会引发压力，即使经验告诉我这通常没什么大不了的，有没有什么心理学或认知方面的解释？

This is something I’ve noticed about myself and I’m curious about the underlying mechanism.Whenever I receive a letter or email that looks official — from a bank, government office, school, etc. — I feel a spike of anxiety almost immediately. What’s strange is that this happens before I even know what the message actually says.In most cases, it turns out to be routine or harmless. Still, the anxious reaction comes first and sometimes lingers until I fully understand the content.I’m not looking for personal advice, but I’m curious whether this response is tied to how humans process authority, uncertainty, or perceived consequences. Is there any psychological or cognitive explanation for why the anticipation alone triggers stress, even when experience says it’s usually nothing serious?
