人们的认知不同可以用英文表示为 "people have different perceptions" 或 "people perceive things differently."

认知是指人们对世界的理解和感知。人们可能会因为自己的经验、文化、教育、信仰等因素对同一件事物有不同的看法或理解。

举个例子：

"Some people see the glass as half full, while others see it as half empty." (有些人觉得这杯水半满，有些人觉得半空。)
"Different people have different interpretations of the same artwork." (不同的人对同一件艺术品有不同的理解。)
"People have different perceptions of beauty. What one person finds attractive may not be appeapng to someone else." (人们对美的理解不同。一个人认为美丽的东西，可能对另一个人来说并不吸引人。)
