&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; "We like to think that we make decisions based on our ideas of right and wrong - and we do, to an extent. But according to recent research, our choicves may also be influenced by something as simple as whether we're right or left handed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; That's because rightihanded people are more drawn to things on the right side of a scree or page, while while left-handed people look to the left. 
Cognitive scientist Daniel Casasanto of The New School for Social 
Research says it's part of the 'body-specificity hypothesis' - the idea
 that our physical bodies affect the decions we make
 and the way we communicate with one another. One of the easiest ways to
 measure this hypothesis is by looking at whether a person is a righty 
or a lefty.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'Handedness is a good tool (to use) because it's easily measurable, and 
our hands our important in how we interact with the physical world,' 
explained Casasanto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'In his study, which was published in a recent edition Current Directions
 in Psychological Science, a journal of the Association for 
Psychological Science, Casasanto found that people tend to prefer the 
things that they see or experience on the same side as their dominant 
hand.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'People like things better when they are easier to perceive and interact with,' he says.
 Right-handers interact with their environment more easily on the right 
than on the left, so they come to associate 'good' with 'right' and 'bad' with 'left,' he explained.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'Since about 90 percent of the population is right-handed, people who want to attract customers, sell products, or get 
votes should consider that the right side of a page or a computer screen
 might be the 'right' place to be,' he added.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; We even tend to use 
our dominant side to differentiate positive ideas from negative ones. In
 2004, presidential candidates John Kerry and George W. Bush - both of 
whom are right-handed - gestured more often with their right hands when
 expressing positive thoughts or ideas. In 2008, both Barack Obama and 
John McCain were left-handed, and both candidates used their left hands 
more often when expressing something positive.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The association with positivity extends to the choices everyday people 
make as well. When Casasanto asked study participants to decide between 
two products to buy, two job applicants to hire, or two alien creatures 
to trust, right-handed participants regularly chose the ones on the 
right side of the page, while south-paws chose the ones on the left.


&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; That influence seems to extend beyond the physical world, influencing 
even abstract ideas like intelligence and honesty. Which means that it 
affects the way we understand one another as well, Casasanto says.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'Most of the time, we feel like we understand each other because what a 
word means to me, is close enough to what it means to you,' he says. 'But it's never the same, and what a word means in your mind may depend 
on quirks of your body.'
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;While the preference seems to hold true even for kids as young as 5 
years old, it isn't absolute. People who are right-hand dominant but 
lose the use of that hand, even temporarily, start to associate 'good' 
with 'left' instead of' 'right.'
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 'After a few minutes of fumbling with their right hand, righties start 
to think like lefties,' Casasanto said in a statement. 'If you change 
people's bodies, you change their minds.'"
