OUR BODY

For Right-handers, ‘Right’ Is Might

Over the past few decades, scientists have shown there are many different internal and external factors influencing how we think, feel, communicate and make decisions at any given moment. One particularly powerful influence may be our own bodies, according to new research reviewed in the December issue of Current Directions in Psychological Science, a journal of the Association for Psychological Science.

According to an association press release, cognitive scientist Daniel Casasanto, of The New School for Social Research, has shown that quirks of our bodies affect our thinking in predictable ways across many different areas of life, from language to mental imagery to emotion.

One way our bodies appear to shape our decision-making is through handedness. Through a series of experiments, they found that, in general, people tend to prefer the things that they encounter on the same side as their dominant hand. When participants were asked which of two products to buy, which of two job applicants to hire, or which of two alien creatures looked more trustworthy, right- handers routinely chose the product, person, or creature they saw on the right side of the page, while left-handers preferred the one on the left. These kinds of preferences have been found in children as young as 5 years old.

This preference for things on our dominant side isn’t set in stone. Right-handers who’ve had their right hands permanently handicapped start to associate ‘good’ with ‘left.’ The same goes for righties whose ‘good’ hand is temporarily handicapped in the laboratory, Casasanto and colleagues found. “After a few minutes of fumbling with their right hand, righties start to think like lefties,” says Casasanto. “If you change people’s bodies, you change their minds.”

It’s clear that this association has implications beyond the laboratory. The body-specificity hypothesis may even play a role in voting behaviour— Casasanto points out that many states still use butterfly ballots, with candidates’ names listed on the left and right.

“Since about 90 per cent of the population is right-handed,” says Casasanto, “people who want to attract customers, sell products or get votes should consider that the right side of a page or computer screen might be the ‘right’ place to be.”
