Discover tells of how what we touch impacts our thoughts:
Weight is linked to importance, so that people carrying heavy objects deem interview candidates as more serious and social problems as more pressing. Texture is linked to difficulty and harshness. Touching rough sandpaper makes social interactions seem more adversarial, while smooth wood makes them seem friendlier. Finally, hardness is associated with rigidity and stability. When sitting on a hard chair, negotiators take tougher stances but if they sit on a soft one instead, they become more flexible.
These influences are not trivial – they can sway how people react in important ways, including how much money they part with, how cooperative they are with strangers, or how they judge an interview candidate.
First off, in two experiments reminiscent of another study I’ve written about, Ackerman showed that holding a light or heavy clipboard can affect a person’s decision-making. In a study of 54 volunteers, those who clutched the heavier board rated a job candidate more highly based on their resume, and thought that they displayed a more serious interest in the job. They even rated their own assessments as being more important! However, the boards didn’t affect the recruits’ judgments on areas unrelated to importance, such as the candidate’s ability to get along with others.
