Are you a righty or a lefty? Science says it matters. According to a study published in Current Directions in Psychological Science, you’re likely to prefer things you experience on the same side as your dominant hand. Study subjects were asked to make various choices—which products to buy, which applicants to hire, and the like—and consistently chose the one they saw on their dominant side.
Researchers think it might be due to “fluency,” which means we like things that we perceive and interact with easily. Right-handed people interact with things on the right side of their body more easily, and lefties on their left, so both start to associate that ease of use as “good” or “bad.” Interestingly though, when a person’s dominant hand is handicapped, they switch the “good” association to the other hand. The million-dollar question: What if you’re ambidextrous?
