I received an email and have a link to this SITE. Since it’s not a long article, I have copied below:-
Most of us prefer to be addressed in our right ear, and are more likely grant a request when we receive it in our right ear than our left, researchers have found.
The bias is due to brain asymmetry, said Luca Tommasi and Daniele Marzoli of Gabriele d’Annunzio University in Chieti, Italy, whose findings are published online in the research journal Naturwissenschaften.
Although scientists have known for a long time that the right ear is better at absorbing spoken information, most past studies were in controlled laboratory settings, so there was little evidence for the phenomenon in everyday behavior, according to the researchers.
Tommasi and Marzoli studied ear preference by observing nightclub visitors. In one study, they watched 286 revelers while they were talking, with loud music in the background. In total, 72 percent of interactions occurred on the right side of the listener, the researchers found.
In a second study, the researchers approached 160 clubgoers and mumbled something meaningless. They then waited for the subjects to turn their head and offer either their left or right ear. The researcher would then request a cigarette.
Overall, 58 percent offered their right ear for listening and 42 percent their left, but only women showed a consistent right-ear preference, according to the investigators. There was no link between the number of cigarettes obtained and the ear receiving the request in this study.
But in a third experiment, the researchers intentionally addressed 176 clubbers in either their right or their left ear when asking for a cigarette, and reported getting significantly more cigarettes when asking in the right ear than in the left.
Stimuli received in the right ear are processed in the left side of the brain, Tommasi and Marzoli noted. The findings, they added, confirm not only past research with humans, but also with animals. “Our studies corroborate the idea of a common ancestry—in humans and other species—of lateralized behavior during social interactions,” they wrote.
So, next time, speak to someone on the right especially to women?
