One way our bodies appear to shape our decision-making is through handedness. Casasanto and his colleagues explored whether being right-handed or left-handed might influence our judgments about abstract ideas like value, intelligence, and honesty.
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.
