Yes, from a sheer mechanical perspective, but there's a reason the brain is predisposed to detect certain forms of signals within the noise of our sensory inputs. If you're wired to be more inclined to detect things like movements-as-threat then if you're in a high threat environment it is actually beneficial. Unfortunately that same wiring in a low threat environment presents as paranoia and will probably be detrimental to survival. Now there is a difference between "detect movement," which the brain is wired to do no matter what and the next step of correlating it to "threat!", which could be the result of either biological, environmental, or both.
