Let me introduce you to the Florida Effect.
Conducting a study with students at New York University, psychologist John Bargh told the student the first part of the test would take place in one office, and then the students would be asked to walk down a corridor to another office for the second part.
Half of the group was asked to arrange brief sentences including at least one of the words: Florida, forgetful, bald, gray, or wrinkle. The other half were presented with a completely random list of words.
He didn’t include the words old or age in that first list. He simply used words associated with being old.
