Which do you think is better, heavy or light? Lighter ones are easier to carry and more convenient, but surprisingly, heavier ones sometimes bring better results.
Here is an experiment that investigated how weight can change people's impressions. A person walking down the street was given a resume and asked to rate the person on the resume based on what was written on it. At this time, the resumes were handed between either a light clipboard or a heavy clipboard. As a result, the person who was given the heavier clipboard rated the person on the resume higher than the person who was given the lighter clipboard, even though the content of the resumes were the same.
Heavy clipboard associates person has more weight(value). And they feel like the person in the resume is an important person. This means people's behavior is influenced by their appearance and other first impressions, even if they are not aware of it, and this seems to be the same with the weight.
Some studies have shown that people who eat with a heavy spoon rate the taste of the food higher than those who eat the same food with a light spoon. Heavy chopsticks = important food = you feel you are eating good food.
There is also this story. A person ate at one of the world's finest restaurants. At that time, the restaurant was experimenting with wooden tableware. So the person ate his food using the finest wooden tableware. He said that he felt like he was eating take-out food with a broken tip spoon.
Also, I love Korean food, but Korean restaurants often serve very heavy iron chopsticks. Perhaps the weight of the chopsticks enhances the taste of Korean food. Why don't you all try using thick paper for your own business cards and resumes, or use heavy plates and heavy chopsticks when serving food to friends?
