You see, the human mind basically has 3 filters; the croc brain, limbic brain and the neo cortex.
The croc brain is survival-focused. And it is the information gatekeeper. Like what to pay attention to and what to skip.
This means it only passes on the information to the action-taking layers (limbic and neo cortex) if what it sees is food, fight, flight, sex, safety or a definite solution to their lurking need.
