I was watching Jarhead yesterday and in one scene the jarheads approached a roaming group of Kuwaitis and one of the soldiers raised his left hand to them (as if in greeting or to say 'Avast!'). Anyway, he was quickly reproached by his fellow because (paraphrase): 'That's an insult; they wipe their asses with their left hand'. I'm curious to see how many members of our enlightened scientific community have a left/right hand bias, not just in the loo, but in life in general.
For example, my aunt, even when her right hand is busily occupied, refuses to shake hands with a friend until her hand is freed up. Where we come from, food is only eaten with the right hand, things are exchanged only with the right, we shake hands with the right, and we wipe with the left. Shaking hands with my left doesn't even feel normal to me. I'm not sure if most Americans share these idiosyncracies but my aunt certainly scorns them for being so uncultured in this respect.
So,
anyone have any anthropological clues as to where this bias stems from and whether there are/have been any societies recorded as having a left-hand bias?
