这是一个关键的产品心理学洞察。在 AI 产品中，“精准”往往比“全面”更重要。用户可以忽略缺失的信息，但很难容忍错误的打扰。这种对“信噪比”的极致追求，解释了为什么舍弃全量记录、转而通过 Enter 键捕捉确定性意图是更优解。

A mental map (or cognitive map) is our mental representation of a place. It includes features we consider important, and is likely to exclude features we consider unimportant.

(Urban planner Kevin Lynch, early 1960s)<br> Elements of mental maps

• paths
• edges - boundaries and endings
• nodes - focal points like squares and junctions
• districts
• landmarks

Modern maps could use augmented and virtual reality to help clarify those elements, making a place easier to navigate and use. But they can also add useless noise that makes the place seem more confusing than it actually is.
