Although both sides are crucial for sanity, right brain is considered emotional and creative while left is more for analytical and logical process. Apt to this dichotomy, new research suggest left brain has more ego than right!!
"Psychologists have used an inventive combination of techniques to show that the left half of the brain has more self-esteem than the right half. The finding is consistent with earlier research showing that the left hemisphere is associated more with positive, approach-related emotions, whereas the right hemisphere is associated more with negative emotions.
Ryan McKay and colleagues used a version of the self-esteem 'implicit association test' (IAT). This compares how readily participants associate themselves or other people with positive words like 'capable' and negative words like 'boring'. Forty-six participants used keyboard keys to categorise words as self-related (e.g. 'me', 'myself'), other-related ('they', 'themselves'), positive or negative. To take one example, people with high self-esteem should be relatively quicker when the same response key is used to categorise self-words and positive words, than when the same key is used to categorise other-related and positive words.
A key twist to this study is that McKay's team used an auditory version of the IAT - the first time this has ever been done. Specifically, they used so-called 'dichotic presentation' such that when a word was presented via headphones to one ear, the same word was played backwards to the other ear. This has the effect of ensuring that the word is only processed by the hemisphere opposite the presenting ear, thus allowing the participants to perform the IAT test with just one hemisphere at a time.
As you'd expect, a participant's self-esteem as measured via one hemisphere tended to correlate with their self-esteem as measured via the other hemisphere. More intriguingly, however, a consistent finding was that participants clocked up higher self-esteem scores when hearing words via their right ear (processed by the left hemisphere) compared with via their left ear (processed by the right hemisphere)."
I guess, compromises will have a better leverage if we sat on the left side to an egoist and of-course brown nosing will be much more effective from the right side. Hmm these pleasures of neuroscience ...
