If you want ask for a favor, ask for it from a person’s right side. Italian researchers have found that people respond more favorably to requests made to the right ear. They believe this is true because of the way the human brain is wired, allowing the right ear to have dominance for listening to verbal stimuli.
As part of this research, scientists visited a noisy nightclub and asked more than 170 people for cigarettes. They obtained significantly more smokes when they spoke into the clubbers’ right ear compared to requests made to those who listened with their left.
According to the researchers, their studies confirm a right ear advantage for verbal communication because this ear is hooked into the left side of the brain. It is that hemisphere that is primarily responsible for interpreting language.
