The reason your job isn’t to look out the window and determine if it is raining, as popularly supposed by stupidifying memes is as follows:

Most of ‘what is going on’ is not, like rain, obvious, but rather the progeny of the results of purpose, perception and cognition… particularly representational cognition, which is not about what exists, but rather, what and how situations undergo purposeful derivation in language, category and cognitive »behavior.

Representational cognition doesn’t tell you what exists, is going on, or is true (with rare exceptions). Rather, it tells you what is motivating your mind, how that came to be, and what the results of »your mental behavior are.
