I guess that sounds like an alarm call to summon the forum autists.

Lying, in somewhat loose definitions, has been witnessed in a lot of rather unintelligent mammals. So hypothetical aliens wouldn't just be un-human-like, but also very un-earth-animal-like if unable to recognize basic social conventions like deception.
Getting used and using others is much of what all social animals with brains do for survival.
One theory has such one-upmanship being the force that caused the rapid hominid brain size increase over the past couple million years. Social manipulation is hard and detecting it is even harder.
