They "think" that way because that's the way they would act or interact with the world. This does not mean that a liar can more easily spot a lie or a thief a thief. Just that that's the way they view the world. Observations should not be limited to just what you think about and is not always easier to spot something just because you're "thinking" about it. Observation is a skill you need to work at and what you observe is entirely dependent on what "you" can actually observe.

Any advanced race that manages to cross the vast distances to "invade" us would likely only consider us pests at best. Likely about the level we think of raccoons. At worst they'd ignore us since nothing we could do would even reach the level of inconvenience.

The ability to know you could do so much better but don't have the ambition or drive to bother.
