It is a fact that smells affect the way we think and process information. Studies have shown that odors trigger all sorts of cognitive changes in humans, and can be used by corporations or the government to influence populations and even intentionally “zombify” people who don’t fit the mold of accepted behavior and thought.
A 2011 study published in the journal Sensors is one such paper that explains how intentional odor exposure influences brain function, producing shifts in mood, thought, and understanding. Much like drugs, scents contain unique pharmacological properties that enter the bloodstream upon inhalation, where they eventually cross the blood-brain barrier and trigger cognitive changes.
